In the previous article we analyzed the Arouter routing jump, this article we analyze the Interceptor interceptor. First, the interceptor also produces the corresponding file during the IDE compilation process. (See Arouter source Analysis 01-Compile the generated file) public class arouter$ $Interceptors $ $app implements Iinterceptorgroup { @Override public

SpringMVC-detailed interceptor process, use and customize interceptor First, let's look at what the interceptor does: 1. Logging: records the request information logs for information monitoring, information statistics, and calculation of PV (PageView. 2. Permission check: for example, if logon is detected, go to the processor check to check whether or not to log

First, Interceptor method The EJB3 can intercept and overwrite bean methods through interceptors. This is somewhat like the around in AOP. The around method of AOP can modify the return value, parameter value of the blocked method, and even cancel the execution of the blocked method. EJB3 interceptors can be used in stateless session beans, stateful session beans, and message-driven bean (MDB) methods. The easiest way to implement interceptors is to

When configuring a package, you can specify the default interceptor for it. Once a default interceptor is specified for a package, if the action in the package does not explicitly specify the interceptor, the default interceptor will take effect. Note: once an interceptor is
