I'm trying to set up a skeleton Spring 3 MVC project but i'm having difficulties getting the views to render. I have followed the structure as described in the mvc-basic sample project and at http://blog.springsource.com/2009/12/21/mvc-simplifications-in-spring-3-0/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Interface21TeamBlog+%28SpringSource+Team+Blog%29 to set up the web.xml, app-config.xml and mvc-config.xml files. The controller gets called but when it reaches the point of finding the view and rendering it i get a 404 error. The files are as follows:
web.xml:
<?xml version="1.0" encoding="UTF-8"?>

In "Java Resources : src" -> com.myProject -> HelloWorldController.java i have:
package com.myProject;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping(value="/helloworld")
public class HelloWorldController {
@RequestMapping(method=RequestMethod.GET)
public ModelAndView helloWorld() {
ModelAndView mav = new ModelAndView();
mav.setViewName("helloworld");
mav.addObject("message", "Hello World!");
return mav;
}
@RequestMapping(value="/Second", method = RequestMethod.GET)
public ModelAndView Second(){
ModelAndView mav = new ModelAndView();
mav.setViewName("Second");
mav.addObject("message", "Hello World!");
return mav;
}
}
and in WebContent/WEB-INF/views i have:
WebContent (folder)
WEB-INF (folder)
views (folder)
helloworld (folder)
helloworld.jsp (.jsp view)
helloworld.jsp (.jsp view)
welcome.jsp (.jsp view)
The views have straighforward html in them. When i request http://localhost:8080/projectname/app i correctly get the the views -> welcome.jsp page. However when i request http://localhost:8080/projectname/app/helloworld or http://localhost:8080/projectname/app/helloworld/ execution hits the correct controller actions but i get HTTP Status 404 - /projectname/WEB-INF/views/helloworld.jsp
Can anyone advise as to what is wrong?
Thanks
The Spring Web model-view-controller (MVC) framework is designed around a DispatcherServlet that dispatches requests to handlers, with configurable handler mappings, view resolution, locale and theme resolution as well as support for uploading files.
React + Spring Boot Microservices and Spring The View is responsible for rendering the model data and in general it generates HTML output that the client's browser can interpret. The Controller is responsible for processing user requests and building an appropriate model and passes it to the view for rendering.
Creating Spring MVC Application in STS or Eclipse Step 1: Create New Spring Project from the menu. Step 2: In the new project window, give the name as “SpringMVCExample” and chose template as “Spring MVC Project”. If you are using this template for the first time, STS will download it from SpringSource website.
There are a few issues. The first one is that you only dispatch /app/* urls to Spring in your web.xml:
<url-pattern>/app/*</url-pattern>
That's fine if the request mapping was /app/helloworld, but means that /helloworld doesn't even get to spring. What you're probably wanting to do is to use a urlrewrite filter to map requests into the /app/* space.
Take a dependency on tuckey and then add this to your web.xml:
<filter>
<filter-name>UrlRewriteFilter</filter-name>
<filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>UrlRewriteFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
Then add a file called urlrewrite.xml in your WEB-INF directory, containing:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.0//EN" "http://tuckey.org/res/dtds/urlrewrite3.0.dtd">
<urlrewrite default-match-type="wildcard">
<rule>
<from>/images/**</from>
<to>/images/$1</to>
</rule>
<rule>
<from>/scripts/**</from>
<to>/scripts/$1</to>
</rule>
<rule>
<from>/styles/**</from>
<to>/styles/$1</to>
</rule>
<rule>
<from>/**</from>
<to>/app/$1</to>
</rule>
<outbound-rule>
<from>/app/**</from>
<to>/$1</to>
</outbound-rule>
</urlrewrite>
After that, a request to /helloworld should go to the correct place. You'll probably want to change the root view controller too:
<mvc:view-controller path="/" view-name="welcome"/>
