Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the specific embodiments of the present invention with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
Some noun explanations used in the present invention:
1. spring Boot: is a brand new framework provided by the Pivotal team, and is designed to simplify the initial building and development process of new Spring applications. The framework is configured in a particular manner so that developers no longer need to define a templated configuration.
2. Spring Cloud: is an ordered set of a series of frames. The development convenience of the Spring Boot is utilized to skillfully simplify the development of the infrastructure of the distributed system, such as a service center, a configuration center, service registration, service discovery and the like, and the development style of the Spring Boot can be used for one-key starting and deployment.
The service center is also called a registration center, and manages various service functions including registration, discovery, fusing, loading, degradation and the like of the service; the configuration center refers to that all public configurations are stored in the same code warehouse git or svn, then the configuration center can read the configurations from the code warehouse and issue the configurations in the form of restful, and then other services can acquire configuration information through calling interfaces; service registration: registering the service instance to a service center when the service instance is started, and canceling the instance when the service instance is stopped; service discovery: when a current service instance requests another service instance, the service center is first addressed and then the request is sent to the available instance.
3. XML: refers to an extensible markup language (Extensible Markup Language) designed to transfer and store data, such as configuration to be loaded at system start-up, etc.
4. YAML: is a recursive abbreviation for "YAML Ain't a Markup Language" (YAML is not a markup language). YAML's grammar is similar to other higher-order languages and can simply express the data morphology of a manifest, hash table, scalar, etc.
The first embodiment of the invention provides a public component configuration method, which improves the prior art, reduces development cost and improves migration transformation efficiency.
Embodiment one:
FIG. 1 is a schematic diagram of a prior art component initialization API, which is seen to be either redis, ftp, resend or simpletimer, which has the common feature that the parameters of the API need to explicitly specify the loading path, i.e., the absolute path, of the XML file.
FIG. 2 is a schematic diagram of a prior art configuration process for a common component, including the steps of: (1) According to the XML configuration file node hierarchical structure, writing a YAML configuration file; (2) The XML configuration file is read before the common component is migrated, and the YAML configuration file is read after the common component is migrated.
Since after migration, the Spring Cloud configuration center cannot directly load and parse the XML file, the XML configuration file used by the components in the old project must be uniformly transformed into the YAML file, but after the configuration file is changed into the YAML file, the common components must be changed in code layer to meet the requirement of reading the YAML file, once the number of project reference components is large, the more the place the code needs to be changed, the longer the migration needs, and when some common components are used in one project, the upgrade components may affect the operation of other projects.
Fig. 3 is a flowchart of a method for configuring a public component according to an embodiment of the present invention, as shown in fig. 2, the method may include the following steps:
s1: the method comprises the steps of filling configuration contents, based on a Spring Cloud configuration center, filling XML configuration contents required to be loaded by a component into a YAML file based on the fact that component codes are not modified, specifically compressing the XML configuration contents into a row of characters, filling the characters into values of the YAML file, and assuming that N parameters required to be configured by a certain component exist, N rows of configuration nodes of the YAML file exist, but one row of YMAL file is used for storing one XML compressed content, only one configuration node exists in the configuration items, and therefore the conversion of the multi-node configuration items into single-node configuration items can be realized.
S2: and (3) performing component configuration, entering a JAVA adapter mode, namely automatically loading an adapter for converting YAML configuration into an XML file, acquiring the name of the component, completing the configuration of the component according to the configuration content of the YAML file in the step S1, specifically, generating a corresponding XML configuration file according to the configuration content of the corresponding component in the acquired YAML file, taking the absolute address of the XML configuration file as an entry, transmitting the entry to the component, and calling a component API to complete the configuration of the component.
The multi-node configuration item is converted into a single-node configuration item in step S1 as follows:
a: examples of multi-node configuration:
b: converted single-node configuration example:
in step S2, the specific operation of the adaptive component calling the API by using the JAVA adapter mode is as follows:
firstly, extracting component configuration item content from a YAML file, and acquiring compressed component configuration content through a component KEY, namely, an XML content as a Value is exemplified as follows:
taking Redis component as an example, JAVA reads YAML configuration item code as follows:
String redisConfigContent=Environment.getProperty(“common.component.redis”);
at this time, the value of the variable redisConfigContent is the XML configuration content of the Redis component.
Then a component XML configuration file is generated, such as an ftp component generates ftp.xml, a Redis component generates redis.xml, and so on, for example, the generated Redis component is configured as follows:
<?xml><redis><ip>10.153.2.12</ip><port>21</port>…</redis>
in the prior art, if implemented according to the multi-node configuration item scheme, a component must add an API in the original RedisHelper class to initialize the YAML file, for example, the Redis helper. InitYamlConfig (parameter is a YAML file path), each configuration item corresponding to a YAML file node needs to add a code line to parse and assign to a designated member variable, and if the component has more configuration items, more codes are involved.
In this embodiment, only one adapter is needed, which is specially responsible for generating an XML file from the extracted XML configuration content, and then transmitting the file path as a parameter to the original component API, so that the modification of the interior of the component is not needed, and only one adaptation is made on the outer layer of the component.
Fig. 4 is a specific flowchart of a common component configuration process of the present embodiment, including the steps of:
1) The boot load adapter: when the service is started, an adapter for converting YAML configuration into an XML file is automatically loaded;
2) Acquiring corresponding configuration content, namely Value, from the YAML configuration file according to the current component name, namely the key name;
3) Returning the configuration content of the current component, namely Value;
4) Generating an XML configuration file according to the component configuration content acquired from the memory, and taking the name of the component Key as a file name, wherein the extension name of the file is XML;
5) The method comprises the steps of inputting a parameter XML configuration file address, calling a component API, and initializing a component;
6) The current component configuration is completed;
7) And (5) performing circulation traversal, loading other components, and completing component configuration.
In the embodiment, the common component configuration is classified, compressed, stored and read according to the component name, so that the conversion from multi-node configuration to single-node configuration is realized, unified and centralized configuration of XML file contents in the YAML file is realized, the XML content format is not influenced, a JAVA adapter mode is used, modification of common component codes is avoided, and the self-adaptive component can call an API, thereby shortening the development test period, accelerating the migration progress of the project and ensuring the quality of the project to a certain extent.
In a second embodiment of the present invention, as shown in fig. 5, a configuration device for a public component is provided, which is a block diagram of the configuration device for a public component in this embodiment, and includes: filling configuration content device: the XML configuration content required to be loaded by the component is filled into the YAML file; component configuration means: and the Java adapter is used for entering a JAVA adapter mode, acquiring the name of the component and completing the configuration of the component according to the YAML file.
In addition, the invention also provides a control device for the configuration of the public components, which comprises:
at least one processor; the method comprises the steps of,
a memory communicatively coupled to the at least one processor; wherein,
