Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

Fig. 1 is a schematic diagram of a main flow of a method for implementing an annotated configuration according to an embodiment of the present invention, which may include:

step S101, reading the configuration file to realize environment setting.

Step S102, creating a component factory class and loading a component definition.

Preferably, the component employed in the present invention is a Bean, and the component factory class is Bean factory. Further, a BeanFactory may be created, and the Bean definition may be loaded.

Step S103, executing the container post processor, then synchronizing the configuration information, and further creating the component object.

Preferably, if the component employed is a Bean, the container post processor is executed and then synchronizes the configuration information, thereby creating the Bean object.

In a further embodiment, when executing the container post processor and then synchronizing the configuration information, this may be done by:

and analyzing the @ ConfigPath and the @ ConfigKey to obtain a Key Value and a Value corresponding to the @ ConfigPath and the @ ConfigKey respectively.

And connecting a remote configuration center, and judging whether a Key Value and a Value respectively corresponding to the @ ConfigPath and the @ ConfigKey exist.

And according to the judgment result, if the Value exists, acquiring the Key Value and the Value of the @ ConfigPath of the remote configuration center, and the Key Value and the Value of the @ ConfigKey to update to the local. And if the Value does not exist, adding the Key Value and the Value of the @ ConfigPath and the Key Value and the Value of the @ ConfigKey after parsing in the remote configuration center.

In a further embodiment, annotations may be added to the Key Value, Value of parsed @ ConfigPath, and the Key Value and Value of parsed @ ConfigKey.

It should be further noted that before updating the configuration information of the remote configuration center (i.e. Key Value and Value of @ ConfigPath, and Key Value and Value of @ ConfigKey of the remote configuration center) to the local, the character string form of the configuration information may be converted into a Value of the data type corresponding to the Key by PropertyEditor of the Spring framework.

As another reference embodiment of the present invention, as shown in fig. 2, this embodiment implements an annotated configuration based on a characteristic of Spring, and the method for implementing the annotated configuration may include:

in step S201, property sources and profiles are parsed to complete the setting of the environment.

Wherein, the configuration file can be read by analyzing the property sources and the profiles.

In step S202, component factory classes are created to build containers.

For example, an IOC (inversion of control) container may be obtained by creating a Bean factory (Bean factory class). Wherein, the IOC (inversion of control) is a law for reducing program coupling.

In step S203, the component definition is loaded.

Wherein the component definitions are for example: the Bean definition (i.e., Bean definition) is used to describe an instance of a Bean, including: attributes, constructors, parameters, and other Bean-related information.

Step S204, executing the container post processor, and synchronizing the configuration information so as to make the configuration information of the local configuration center consistent with that of the remote configuration center.

In the embodiment, the synchronization of the configuration information is performed after the container postprocessor is executed, so that the configuration information is in the latest state when the service logic is executed, the synchronization of the configuration information is perfectly decoupled from the service logic, and the synchronization of the configuration information with the configuration information of the remote configuration center is ensured. The specific implementation process comprises the following steps:

the method comprises the following steps: parsing @ ConfigPath and @ ConfigKey to obtain the Key Value, Value of @ ConfigPath, and the Key Value and Value of @ ConfigKey.

Step two: connecting a remote configuration center, judging whether a Key Value and a Value of the @ ConfigPath after the analysis and a Key Value and a Value of the @ ConfigKey after the analysis exist, if so, executing a third step, and if not, executing a fourth step.

Step three: and acquiring a Key Value and a Value of @ ConfigPath and a Key Value and a Value of @ ConfigKey of the remote configuration center to update to the local.

Preferably, after the configuration information of the remote configuration center is obtained, a character string form of the configuration information may be converted into a value of a data type corresponding to Key through a PropertyEditor (for completing conversion between the data type and the character string) of a Spring framework (which is a design level framework of open source code). The configuration information is Key Value and Value of @ ConfigPath of the remote configuration center, and Key Value and Value of @ ConfigKey.

Step four: and adding the Key Value and the Value of the parsed @ ConfigPath, and the Key Value and the Value of the @ ConfigKey to a remote configuration center.

It is worth mentioning that the remote configuration center can be monitored to monitor the Key Value and the Value of @ ConfigPath and to monitor the Key Value and the Value of @ ConfigKey after either step three or step four is executed.

In step S205, a component object is created, which defaults to a singleton.

For example, a component when a Bean may call the Bean's constructor, creating an instance of the Bean, to create the Bean object.

It should be noted that, in the present invention, since the configuration information is static, when the configuration information needs to be referred to, it can be directly used (i.e. accessible):

class name attribute name

As a further embodiment of the present invention, annotations are added to the Key Value and Value of @ ConfigPath and the Key Value and Value of @ ConfigKey, so that lower intrusiveness to the service can be achieved, that is, compared with the traditional configuration information synchronization mode, the purpose of logical decoupling from the service is achieved by encapsulating the logic of configuration information synchronization into the annotation and container post-processing.

Where @ ConfigPath may indicate that this class is a configuration class, corresponding to a path in the remote configuration center, for example: value "/yanglikun", i.e. configure Path. In addition, the @ ConfigPath has a corresponding read-write permission value, and the method supporting the spring placeholder loads the key under different operating environments according to the profile. For example: readToken ═ $ { ucc. yanglikun. readToken } ", i.e., read the key. writeToken ═ $ { ucc. yanglikun. writeToken } ", i.e., write a key.

Where, the @ ConfigKey may represent specific configuration information (Key, Value), and the default field name is the Key of the remote configuration center, which may also be customized, for example: @ ConfigKey ("custom _ key _ name"), i.e., specifying field values, default field names.

Fig. 3 is an apparatus for implementing the annotated configuration according to an embodiment of the present invention, and as shown in fig. 3, the apparatus 300 for implementing the annotated configuration includes a setup module 301 and a configuration module 302. The setting module 301 reads the configuration file to implement environment setting; create component factory classes, and load component definitions. Thereafter, the configuration module 302 executes the container post-processor and then synchronizes the configuration information, thereby creating the component object.

As a further embodiment, the configuration module 302 executes a container post-processor, and then the specific implementation process of synchronizing the configuration information includes:

And connecting a remote configuration center, and judging whether a Key Value and a Value respectively corresponding to the @ ConfigPath and the @ ConfigKey exist. And according to the judgment result, if the Value exists, acquiring the Key Value and the Value of the @ ConfigPath of the remote configuration center, and the Key Value and the Value of the @ ConfigKey to update to the local. And if the Value does not exist, adding the Key Value and the Value of the @ ConfigPath and the Key Value and the Value of the @ ConfigKey after parsing in the remote configuration center.

Preferably, annotations are added to the Key Value and Value of the parsed @ ConfigPath, and the Key Value and Value of the parsed @ ConfigKey.

It should be further noted that before acquiring the Key Value and Value of @ ConfigPath, and the Key Value and Value of @ ConfigKey of the remote configuration center, the PropertyEditor of the Spring framework converts the string format of the configuration information into the Value of the data type corresponding to the Key. The configuration information is Key Value and Value of @ ConfigPath of the remote configuration center, and Key Value and Value of @ ConfigKey.

It should be noted that, in the implementation of the apparatus for implementing the annotated configuration according to the present invention, the details have been described in the above method for implementing the annotated configuration, and therefore, the repeated contents are not described herein.
