spring mvc interceptor annotation example

In fact, in the mvc:interceptors tag, there are two types of configurations, one that directly configures a bean (bean and ref), and the other to configure the blocked path and the excluded path. The directly configured Bean represents the interception of all requests, while for Mvc:interceptor there is finer control. The Mvc:interceptors attribute, Path-matcher, is to configure a custom Pathmatcher, which is mainly used to handle the matching rules of the path, with the default Pathmatcher antp

Interceptors are for mapping. The corresponding interception can be configured under mapping. Because of the common Mvc:annotation-driven configuration mapping and adapter, the interceptor is configured here with Mvc:interceptors. 1, a single mapping interceptor A, the definition of interceptors.

Spring MVC's Interceptor Interceptor interception request is done by implementing the Handlerinterceptor interface. Next, take an example:Through the interceptor to complete a user rights authentication function-the user must log in to access other pages of the site, if not logged in to access, will be intercepted by t

following aftercompletion The Interceptor method can only be called if the return value of the Prehandle method of the currently-owned class is true. The Posthandle method, as the name implies, is executed after the current request is processed, that is, after the controller method call, but it is called before the view returns to render Dispatcherservlet. So we can manipulate the Modelandview object after controller processing in this method. The Po

Overview Following a major upgrade of Spring 2.0 to Spring MVC, Spring 2.5 introduced the annotation driver for spring MVC. Now you don't have to let Controller inherit any interfaces,

annotation interceptor is implemented to add an annotation to the required interception method @accessrequired Examples of usages in the Spring MVC controller /** * Annotation Blocker method * @return */@RequestMapping (value= "/

The order in which the Servlet filter and Spring interceptor are executed is the filter in order? How do we control the order in which filter is executed? Through Tomcat code analysis, the servlet is called after filter execution is complete, and if multiple filter controls the order of execution, the first thing to do is to configure a parameter in the Web.xml, like order, but find out, the servlet does no

This article is based on spring MVC annotations and lets spring run. Not logged in, do not allow access to the pages within the background folder, how to determine whether to log in. Background is the key directory, and each person who operates the directory needs to write in the log table, how to implement it. Interceptors are one of the implementation scenarios
