The previous blog introduced the concept of interceptors and some of the basics of Struts2 and custom interceptors, but how exactly is the interceptor applied in the actual project, perhaps you are still confused, then this blog we will come up with actual combat, but also a summary of the interceptor and application practice. When we are doing any information management system, we can not avoid to control

Today to learn and understand, filter and SPRINGMVC of the difference between the interceptor, learned a lot of things, has always thought that the interceptor is a filter to achieve, now think of is really a mistake ah, and look at the relatively superficial, not a global and meticulous understanding, due to the late night, time reason, I will take some of the points of view of netizens, we carefully look
Struts2 dynamic call + Servlet filter + struts2 interceptor, struts2servlet On weekends, it's really hard to get bored ...... This article is based on the complete s2sh project. If you are not familiar with the construction of the s2sh project, please refer to the following articles:In eclipse, the struts2 project is built based on tomcat-7.0.82. In eclipse, the struts2 project is built based on the Integrated spring + hibernate. The configuration of

In Struts2, the Interceptor is the essence of the frame, while the two-time parameter Interceptor Paramsprepareparamsstack has a good processing mechanism for solving the problem of data echo and object modification property loss.The following sections are available in the default interceptor configuration in Struts-default.xml (self-locating source code, usually
The Interceptor is triggered when ajax initiates an action, and ajax initiates an action interception. A problem occurred during project creation. When ajax initiates an action and triggers the interceptor, the returned value will not initiate a jump if it does not receive the same result, the pos form t can be used for submission. After a long struggle, I have found a method that is not very scientific. I
Struts2 custom interceptor and struts2 custom Interception The first is the two main files in the struts2 framework: one is the interceptor class and the other is the struts. xml configuration file. To put it simply, one is to explain what to do, and the other is to explain where to do it. Interceptor class Package com. test.
Custom interceptor of Struts2 Login. jsp To customize the Interceptor, you must implement the com. opensymphony. xwork2.interceptor. Interceptor interface. Package struts2.example. interceptor; import com. opensymphony. xwork2.ActionContext; import com. opensymphony. xwo
The interceptor system is an important part of struts2. For the struts2 framework, it can be understood as an empty container. It is precisely a large number of built-in interceptors that have completed most of the operations of the framework. Because the interceptor of the struts2 framework is dynamically configured (instead of being written to the Framework source code in hard coding mode), all developers
The difference between filters and interceptors: ① interceptors are based on the reflection mechanism of Java, and filters are based on function callbacks.The ② interceptor is not dependent on the servlet container, and the filter relies on the servlet container.The ③ interceptor only works on action requests, while filters can work on almost all requests.The ④ interce
Quick learning of AngularJs HTTP Response interceptor and quick learning of angularjs At any time, if we want to add global functions for the request, such as identity authentication and error handling, we can intercept the request before it is sent to the server or when the server returns it, is a good means of implementation. AngularJs provides a global approach for processing through the interceptor. Fou

Today's project encountered the need to parse the data received from the push into a structured data type problem required by the application layer, because of the wide variety of push message types, the number of structured data types that are waiting to be parsed, and some that require a few steps of the parse process, and because of the project's historical reasons, Use Protocal Buffer (the data for push is passed in bytes). In the middle of trying the agent, decoration and other modes, have
Struts2 custom interceptor DevelopmentIntroduction In the previous article has talked about the basic concepts of interceptor (http://blog.csdn.net/xlgen157387/article/details/45951163), below we implement a custom interceptor together.Interceptor Interface public interface Interceptor extends Serializable { /**

1, interceptors are based on the reflection mechanism of Java, filter is based on function callback2. Interceptors are not dependent on the servlet container, and the filter relies on the servlet container3. Interceptors can only work on action requests, and filters will work on almost all requests4. The interceptor can access the action context, the object in the value stack, and the filter cannot5, in the life cycle of the action, the
Interceptors are programmed on a tangent plane to call a method before your service or a method, or invoke a method after the method, such as a dynamic proxy is a simple implementation of the Interceptor, the filter is in the Java Web, you incoming request, Response filter out some of the information in advance, or set some parameters in advance, and then pass into the servlet or struts action for business logic, such as filtering out illegal URLs (no
