Serialization and deserialization are techniques commonly used in the computer arts.

And the deserialization is a serialized inverse process and is used for analyzing the serialized data to obtain the attribute value of the object and assigning the attribute of the object to be reconstructed according to the attribute value.

Detailed Description
The present deserialization method is explained below by way of an example.
User is a class representing a User, User is an object of a User class, i.e. an instance of the User class, and User has attributes: and the user ID, wherein the attribute value of the attribute user ID is 0001, and the attribute value 0001 of the user is converted into serialized data through serialization, such as data in a json format: { "userID": 0001 "}
The process of deserialization is: firstly, obtaining the attribute of the user in a reflection mode: and then obtaining an attribute value corresponding to the attribute by analyzing the serialized data, for example, matching the attribute userID obtained by reflection with the serialized data to obtain an attribute value 0001 corresponding to the attribute userID, and assigning a value to the attribute userID according to the obtained attribute value 0001 to realize the deserialization of the attribute userID. And when all the attributes of the user are assigned, the user of the object is reconstructed.
However, when the attribute of the user is obtained by reflection, more hardware resources are usually occupied, and thus the deserialization efficiency is low.
In addition, this approach has the following problems: because some programming languages do not support obtaining the attributes of the object to be reconstructed in a reflection mode, deserialization may not be achieved; since the serialized data may exist in a plurality of formats, such as an xml format or a json format, different program codes need to be written for different formats to assign values to the attributes of the object to be reconstructed.
The embodiment of the application provides a deserialization method and device, which do not need to obtain the attribute of an object to be reconstructed in a reflection mode, so that hardware resources are saved and deserialization efficiency is improved.
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, an embodiment of the present application provides a method embodiment of a deserialization method, which includes:
101: serialized data is obtained, the serialized data including a first attribute of an object to be reconstructed.
In this embodiment, the serialized data may be data in xml format or json format. For example, the serialized data may be data in json format:
{“userID”:“0001”}
wherein the userID is the first attribute.
The serialized data also includes a first attribute value, and the first attribute has a corresponding relationship with the first attribute value.
102: the serialized data is parsed to generate a first key-value pair.
In this embodiment of the present application, the serialized data may be parsed to generate the first Key-Value pair, where the first Key-Value pair includes first Key information (Key) and first Value information (Value), and the first Key information and the first Value information have a corresponding relationship. Wherein the first key information is used for representing the first attribute, and the first value information is used for representing the value of the first attribute.
For example, if the serialized data is data in json format:
{“userID”:“0001”}
the first key-value pair generated may be:
{User.userID＝0001}
user id is the first key information, and 0001 is the first value information.
103: and assigning the first attribute to the first value information corresponding to the first key information according to the preset corresponding relation between the first key information and the first attribute.
In this embodiment of the present application, since the object to be reconstructed has the first attribute, which is an inherent feature of the object to be reconstructed, the application does not need to obtain the attribute of the object to be reconstructed in a reflection manner, but can preset a correspondence relationship between the first attribute of the object to be reconstructed and the first key information, and assign the first attribute as the first value information corresponding to the first key information according to the correspondence relationship. The first key information may be regarded as a path of the attribute value of the first attribute, and the application actually finds the attribute value of the first attribute, that is, the first value information, using the path, thereby assigning the first attribute using the first value information.
For example, if the first key information is: the user id is 0001, and the correspondence between the first attribute user id and the first key information user is preset, so that the user id may be assigned to 0001 corresponding to the user.
According to the technical scheme, after the serialized data is obtained, the serialized data is analyzed to generate the first key value pair, wherein the serialized data comprises the first attribute of the object to be reconstructed, and the first key value pair comprises the first key information and the first value information which have the corresponding relation. Since the object to be reconstructed has the first attribute, which is an inherent feature of the object to be reconstructed, in this embodiment of the application, the attribute of the object to be reconstructed does not need to be obtained in a reflection manner, but a corresponding relationship between the first attribute and the first key information is preset, so that the first attribute can be assigned as the first value information corresponding to the first key information according to the corresponding relationship, and deserialization of the first attribute of the object to be reconstructed is achieved. Therefore, the attribute of the object to be reconstructed is not required to be obtained in a reflection mode in the embodiment of the application, so that excessive hardware resources are not required to be occupied, and the deserialization efficiency is improved.
In addition, because the application does not need to obtain the attributes of the object to be reconstructed in a reflection mode, the problem of unsupported programming language no longer exists, and the method embodiment of the application is suitable for various different programming languages, such as Java, C # and the like. And the first key value pair is generated according to the deserialized data, and then the first attribute is assigned according to the first key value pair, so that even if the serialized data has different formats, such as an xml format and a json format, the assignment of the first attribute can be realized only by the same program.
In the embodiment of the present Application, the deserialization data may also be obtained by calling an Application Programming Interface (API). Specifically, 101 in the present embodiment includes: calling an API corresponding to the object to be reconstructed; and acquiring return data for calling the API, and taking the return data as the serialized data.
In the above embodiment, only the deserialization process of the first attribute is described, and if the object to be reconstructed further includes other attributes besides the first attribute, the deserialization of the other attributes may be performed in a similar manner. For example, the object to be reconstructed may have at least two attributes, then 102 may analyze the serialized data to generate a key value pair list, where the key value pair list includes at least two key value pairs, and key information and value information in each key value pair have a corresponding relationship, and 103 searches for corresponding value information through the key information in the key value pair list, and assigns the value information to the corresponding attribute of the object to be reconstructed. The following embodiments are described taking as an example that the object to be reconstructed includes two attributes.
Referring to fig. 2, another method embodiment of the deserialization method is provided in the embodiment of the present application, which includes:
201: serialized data is obtained, the serialized data including a first attribute and a second attribute of an object to be reconstructed.
For example, the serialized data may be data in json format:
{“userID”:“0001”，
“userAddress”:“address01”}
the first attribute is an attribute 'userID', and the second attribute is 'userAddress'.
The serialized data also includes a first attribute value and a second attribute value, the first attribute having a correspondence with the first attribute value, the second attribute having a correspondence with the second attribute value.
202: parsing the serialized data to generate a key-value pair list, the key-value pair list comprising a first key-value pair and a second key-value pair.
The first key-value pair comprises first key information and first value information, and the first key information and the first value information have a corresponding relation. The second key-value pair includes second key information and second value information, and the second key information and the second value information have a corresponding relationship. Wherein the first key information is used for representing the first attribute, and the first value information is used for representing the value of the first attribute. The second key information is used for representing the second attribute, and the second value information is used for representing the value of the second attribute.
For example, if the serialized data is data in json format:
{“userID”:“0001”，“userAddress”:“address01”}
the generated list of key-value pairs may be:
{User.userID＝0001，User.userAddress＝address01}
user id is the first key information, 0001 is the first value information, user address is the second key information, and address01 is the second value information.
In the java language, the list of key-value pairs may be stored in a map object.
203: and assigning the first attribute to the first value information corresponding to the first key information according to a preset corresponding relationship between the first key information and the first attribute, and assigning the second attribute to the second value information corresponding to the second key information according to a preset corresponding relationship between the second key information and the second attribute.
For example, if the first key information is user.userid, the second key information is user.useraddress, and the first attribute "userID" and the first key information "user.userid" are preset to have a corresponding relationship, and the second attribute "userAddress" and the second key information "user.useraddress" are preset to have a corresponding relationship, so that the "userAddress" may be assigned to 0001, that is, the "userAddress" may be assigned to 0001, and the "userAddress" may be assigned to address01, that is, the "userAddress may be assigned to address 01.
It should be further noted that, in the present application, the first key value pair is generated according to the deserialization data, and then the first attribute is assigned according to the first key value pair, instead of being directly assigned according to the deserialization data, which also has a technical effect of reducing the number of times of parsing the deserialization data. For example, if the serialized data is data in json format:
{“userID”:“0001”，
“userAddress”:“address01”}
the object to be reconstructed has two properties: and if the two attributes are directly assigned without generating the first key value pair, analyzing the deserialized data at least twice, wherein the first analysis is as follows: matching the attribute userID with the deserialized data to obtain an attribute value 0001 corresponding to the attribute userID, and analyzing for the second time as: and matching the attribute useradaddress with the deserialized data to obtain an attribute value of address01 corresponding to the attribute useradaddress. And if the deserialization method provided by the application is adopted, no matter how many attributes the object to be rebuilt has, the deserialization data only needs to be analyzed once to generate a key value pair list, and then the attributes of the object to be rebuilt are assigned according to each key value in the key value pair list. Therefore, the data to be serialized do not need to be analyzed for multiple times, and the workload is reduced.
In this embodiment of the present application, the first attribute may be a simple type or a complex type, which are described below.
Simple type means that the first attribute has no sub-attribute, i.e. the first attribute is a direct attribute of the object to be reconstructed. For example, the deserialization data is data in json format:
{“userID”:“0001”}
the userID is a direct attribute of the object user, so that the userID belongs to a simple type.
For a simple type, 103 may assign the first attribute as the first value information directly.
For example, the first key-value pair generated may be:
{User.userID＝0001}
user id is the first key information, and 0001 is the first value information.
The first attribute may be assigned by the following Java code:
user.setuserID(map.get("User.userID"))；
the code table shows a correspondence relationship between a preset first key information user. The map object stores the first key-value pair.
And in the code, the user ID and the user are both of character string types, so that type conversion is not needed. If the user id is a character string type and the user id is another type, for example, an int type, data conversion is required, and the first attribute may be specifically assigned by the following Java code:
user.setUserID(Integer.valueOf(map.get("User.userID")))；
the complex type means that the first attribute has a sub-attribute. For example, the deserialization data is data in json format:
{"vpcAttributes":{"NatIpAddress":"Address02"},
and the NatIPaddress is a sub-attribute of the first attribute vpcAttributes.
In this embodiment of the present application, if the first attribute is a complex type, this embodiment of the present application may further include: establishing a first sub-object of the object to be reconstructed; wherein the first sub-object is actually the first attribute. 103, assigning the first attribute to the first value information corresponding to the first key information according to the preset correspondence between the first key information and the first attribute, including: and assigning the attribute of the first sub-object to the first value information corresponding to the first key information according to the preset corresponding relation between the first key information and the sub-attribute. The following examples are given.
Still taking the data in json format as an example, the first key-value pair generated may be:
{User.VpcAttributes.NatIpAddress＝Address02}
wherein, user.vpcatributes.natipaddress is the first key information, and Address02 is the first value information. Wherein the first key information corresponds to the first attribute and a sub-attribute of the first attribute.
The child object vpctatributes may be built by the following Java code:
VpcAttributes vpcAttributes＝new VpcAttributes()；
the attributes of the sub-object vpctatributes can be assigned by the following Java code:
vpattatributes. setnatipaddress (map. get ("user. vpattatributes. natipaddress")); the code table shows a correspondence relationship in which the first key information user vpcatributes NatIpAddress and the child attribute NatIpAddress are set in advance.
In this embodiment of the present application, the first attribute may also be in a collection format, and at this time, the first attribute may be assigned in a round-robin manner. Specifically, the method further comprises: establishing a second sub-object of the object to be reconstructed, wherein the second sub-object is of a set type; 103, assigning the first attribute to the first value information corresponding to the first key information includes: assigning the attribute of the second sub-object to the first value information corresponding to the first key information in a circulating manner to obtain the attribute value of the second sub-object; and assigning the first attribute as the attribute value of the second sub-object. The Set format may be a list format, a Set format, or an array format. The collection type may be a list type, a Set type, or an array type, etc.
The above-described cyclic assignment is exemplified below.
The deserialization data may be data in a josn format:
{"InnerIpAddress":
["10.165.103.41"，"10.165.103.42"]}
wherein InnerIpAddress is the first attribute, and the first attribute is in a set format.
The first key-value pair generated may be:
{User.InnerIpAddress[0]＝10.165.103.41}
wherein user. lnneripaddress [0] is the first key information, and 10.165.103.41 is the first value information. Wherein the first key information can indicate that the first attribute is in an aggregate format and can indicate that the first value information is located at a position of the first attribute in the aggregate format. Lnneripaddress [0] for example, indicates that the first value information is the 0 th bit of the first attribute.
The second child object lnneripaddress may be established by the following Java code:
List<String>innerIpAddress＝new ArrayList<String>()；
the second child object lnneripaddress may be assigned by the following Java code:
the first attribute may be assigned by the following Java code:
user.setInnerIpAddress(innerIpAddress)；
and the user is the object to be reconstructed.
Corresponding to the above method embodiment, the present application further provides an embodiment of an deserializing device, which is specifically described below.
Referring to fig. 3, an embodiment of the present application provides an apparatus embodiment of an deserializing apparatus, which includes: an acquisition unit 301, a generation unit 302 and an assignment unit 303.
The acquisition unit 301 is configured to acquire serialized data, which includes a first property of an object to be reconstructed.
In the embodiment of the application, the serialized data may be data in an xml format or a json format.
The serialized data also includes a first attribute value, and the first attribute has a corresponding relationship with the first attribute value.
The generating unit 302 is configured to parse the serialized data to generate a first key-value pair.
In this embodiment of the application, the generating unit 302 may analyze the serialized data to generate the first key-value pair, where the first key-value pair includes first key information and first value information, and the first key information and the first value information have a corresponding relationship. Wherein the first key information is used for representing the first attribute, and the first value information is used for representing the value of the first attribute.
The assigning unit 303 is configured to assign the first attribute to the first value information corresponding to the first key information according to a preset correspondence between the first key information and the first attribute.
In this embodiment of the present application, since the object to be reconstructed has the first attribute, which is an inherent feature of the object to be reconstructed, the application does not need to obtain the attribute of the object to be reconstructed in a reflection manner, but can preset a correspondence relationship between the first attribute of the object to be reconstructed and the first key information, and assign the first attribute as the first value information corresponding to the first key information according to the correspondence relationship. The first key information may be regarded as a path of the attribute value of the first attribute, and the application actually finds the attribute value of the first attribute, that is, the first value information, using the path, thereby assigning the first attribute using the first value information.
As can be seen from the foregoing technical solutions, after the obtaining unit 301 obtains the serialized data, the generating unit 302 analyzes the serialized data to generate a first key value pair, where the serialized data includes a first attribute of an object to be reconstructed, and the first key value pair includes first key information and first value information that have a corresponding relationship. Since the object to be reconstructed has the first attribute, which is an inherent feature of the object to be reconstructed, in this embodiment of the application, it is not necessary to obtain the attribute of the object to be reconstructed in a reflection manner, but a correspondence between the first attribute and the first key information is preset, so that the assigning unit 303 may assign the first attribute to the first value information corresponding to the first key information according to the correspondence, thereby implementing deserialization of the first attribute of the object to be reconstructed. Therefore, the attribute of the object to be reconstructed is not required to be obtained in a reflection mode in the embodiment of the application, so that excessive hardware resources are not required to be occupied, and the deserialization efficiency is improved.
In addition, because the application does not need to obtain the attributes of the object to be reconstructed in a reflection mode, the problem of unsupported programming language is avoided, so that the device embodiment of the application is suitable for various different programming languages, such as Java, C # and the like. And the first key value pair is generated according to the deserialized data, and then the first attribute is assigned according to the first key value pair, so that even if the serialized data has different formats, such as an xml format and a json format, the assignment of the first attribute can be realized only by the same program.
In the embodiment of the present application, the deserialization data may also be obtained by calling an API. Specifically, the obtaining unit 301 in this embodiment is specifically configured to: calling an API corresponding to the object to be reconstructed; and acquiring return data for calling the API, and taking the return data as the serialized data.
In the above embodiment, only the deserialization process of the first attribute is described, and if the object to be reconstructed further includes other attributes besides the first attribute, the deserialization of the other attributes may be performed in a similar manner. For example, the object to be reconstructed may have at least two attributes, the generating unit 302 may analyze the serialized data to generate a key value pair list, where the key value pair list includes at least two key value pairs, and key information and value information in each key value pair have a corresponding relationship, and the assigning unit 303 searches for corresponding value information through the key information in the key value pair list and assigns the corresponding attribute to the object to be reconstructed.
For example, the serialized data also includes a second property of the object to be reconstructed. The serialized data further comprises a second attribute value, and the second attribute value have a corresponding relation.
The generating unit 302 is further configured to parse the serialized data to generate a second key-value pair, where the second key-value pair includes second key information and second value information, and the second key information and the second value information have a corresponding relationship. The second key information is used for representing the second attribute, and the second value information is used for representing the value of the second attribute. The first key-value pair and the second key-value pair may form a list of key-value pairs. In the java language, the list of key-value pairs may be stored in a map object.
The assigning unit 303 is further configured to assign the second attribute to the second value information corresponding to the second key information according to a preset correspondence between the second key information and the second attribute.
It should be further noted that, in the present application, the first key value pair is generated according to the deserialization data, and then the first attribute is assigned according to the first key value pair, instead of being directly assigned according to the deserialization data, which also has a technical effect of reducing the number of times of parsing the deserialization data.
In this embodiment of the present application, the first attribute may be a simple type or a complex type, which are described below.
Simple type means that the first attribute has no sub-attribute, i.e. the first attribute is a direct attribute of the object to be reconstructed. For a simple type, the assigning unit 303 may assign the first attribute as the first value information directly.
The complex type means that the first attribute has a sub-attribute. In this embodiment of the present application, if the first attribute is a complex type, the apparatus of this embodiment of the present application may further include: a first establishing unit, configured to establish a first sub-object of the object to be reconstructed; the assignment unit 301 is specifically configured to: and assigning the attribute of the first sub-object to the first value information corresponding to the first key information according to the preset corresponding relation between the first key information and the sub-attribute.
In this embodiment of the present application, the first attribute may also be in a collection format, and at this time, the first attribute may be assigned in a round-robin manner.
