JFinal Approval Implementation Guide

To implement the approval function, you can use interceptors in the JFinal framework. First, you need to create an approval interceptor class that extends the JFinal Interceptor class and overrides the intercept method, which will be called before the request reaches the Controller.

In the approval interceptor class, you can write approval logic such as checking if the current user has approval permissions. If they do, allow the request to pass through. If not, block the request and return the appropriate error message.

Next, in the configuration class of JFinal, you can add the approval interceptor to the global interceptor list through the addInterceptor method, or use the @Before annotation in the Controller to add the approval interceptor to a specific Controller or Action.

By following the steps above, approval functionality can be implemented in the JFinal framework. When a user requests an interface that requires approval, the interceptor will intercept the request and execute the approval logic, thus achieving approval functionality.
