No mapping found for HTTP request with URI [/myappname/] in DispatcherServlet with name 'appServlet'

问题

I have got error No mapping found for HTTP request with URI [/myappname/] in DispatcherServlet with name 'appServlet' when I was starting my project on JBoss. This is issue has occurred after resolving another issue described here: "No Session found for current thread" after changing access method to the session

Before everything was working fine. I am using Apache Tiles 2. I am reading few similar questions but I can't find working solution.

This is my DispatcherServlet Context file without Hibernate configuration:

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/mvc"
         xmlns:tx="http://www.springframework.org/schema/tx"

    <beans:property name="viewClass" value="org.springframework.web.servlet.view.tiles2.TilesView" />
</beans:bean>

My web.xml whole file:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</context-param>

</servlet>

<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>

And this is my IndexController:

@Controller
public class IndexController {

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String index(Model model, Principal principal) {
        return "index";
    }
}

What is wrong with my configuration at this moment?

回答1:

I think your are missing <mvc:annotation-driven/> which is required to read the @Controller and @RequestMapping annotations. You can read more on this here and here.

回答2:

The solutio is to keep in DispatcherServlet Context file both annotation-driven tags like here:

<annotation-driven />
<tx:annotation-driven />

I haven't found similar solution so I am gooing to leave it here.

回答3:

Have this in your spring servlet.xml file

xmlns:mvc="http://www.springframework.org/schema/mvc
xmlns:tx="http://www.springframework.org/schema/tx"

and

http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.5.xsd

and

<mvc:annotation-driven />
<tx:annotation-driven />

In your controller class, use

 @Controller
 public class IndexController {..}

and it works!

回答4:

I was facing the same exception and was trying all above solutions but nothing helped but I did get a pointer the issue was because the class was not generated in the target class folder and it was due to incorrect Maven Project Structure which was leading to no compilation of Java controller class.

Check if you have below structure and then if class is generated in target->class folder then only try above suggestions.

Project
  src
    main
      java
      resources
    test
      java
      resources

回答5:

Make sure that your .java file is under src/main/java instead src/main/resources
