How to use MyBatis interceptors?

The method of using MyBatis interceptors is as follows:

1. Create an interceptor class that implements the Interceptor interface. This interface specifies four methods: intercept, plugin, setProperties, and getProperties.
2. Implement custom interception logic in the intercept method. This method receives an Invocation object, which can be used to obtain information such as the target method and parameters, and execute custom logic at the appropriate time.
3. Wrap the target object in the plugin method and return a proxy object. The wrap method of the Plugin class can be used to achieve wrapping, which takes three parameters: the target object, an interceptor, and property arguments. The proxy object returned will intercept method calls to the target object and execute the logic of the interceptor.
4. Configure interceptors in the MyBatis configuration file. Use the tag to add the interceptors to the tag, multiple interceptors can be configured.
5. Option: Implement the `setProperties` method in the interceptor class to receive the configured properties as parameters. These parameters can be accessed through the `properties` attribute of the Interceptor interface.
6. Optional: Implement the getProperties method in the interceptor class to return the configuration properties of the interceptor.

By following the above steps, you can create custom interceptors and use them in MyBatis. Interceptors can be used for functionalities such as logging, performance monitoring, and access control.
