This article provides you with Spring MVC Framework configuration skills to help you manage multiple instances of Spring-based web applications. This configuration governance topic is often ignored by academia, but this is especially important for practical Web development. This topic is not directly related to any specific technology. Therefore, we will describe

Introduction to Web MVC 1.1, the request-response model in Web development: In the Web world, the steps are as follows: 1, Web browsers (such as IE) initiate a request, such as access to http://www.cnblogs.com 2. The Web server (such as Tomcat) receives the request, processes the request (for example, the user adds it, saves the user), and finally produces a response (typically HTML). 3. After the Web serve

easier.Iv. what features does Spring boot offer? 1. No need to manually manage versions of dependent jar packagesSpring boot manages all dependent versions that it provides through the Spring Boot starter project, and these dependent versions are upgraded when spring boot is upgraded. You do not need to specify a version number, but you can also override the def

@RequestMapping (value = "/user/save", method = Requestmethod.post) Public Modelandview Saveuser (httpservletrequest request, HttpServletResponse Response,usermodel user) throws Exception { Modelandview mv = new Modelandview ("/user/save/result");//default to Forward mode Modelandview mv = new Modelandview ("Redirect:/user/save/result");//redirect mode Mv.addobject ("message", "Save user success!") "); return MV; } And after

management, you do not need to explicitly provide log dependencies. For example, if you are creating an application context, the Dependency injection configuration for Maven is as follows:org.springframeworkspring-context4.1.1.RELEASERuntimeIt is important to note that if you do not want to compile with the spring API , scopes can be declared as runtime.
