Spring MVC: RequestMapping both class and method

Question

Is this possible?

@Controller
@RequestMapping("/login")
public class LoginController {

    @RequestMapping("/")
    public String loginRoot() {
        return "login";
    }

    @RequestMapping(value="/error", method=RequestMethod.GET)
    public String loginError() {
        return "login-error";
    }

}

I got a 404 error when accessing localhost:8080/projectname/login but not in localhost:8080/projectname/login/error.

Here's my web.xml project name

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>

<servlet>
    <description></description>
    <servlet-name>projectname</servlet-name>
    <servlet-class>
        org.springframework.web.servlet.DispatcherServlet
    </servlet-class>
</servlet>

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

Answer 1

You don't need the / in the method's mapping. Just map it to "".

Answer 2

You don't need to "/" and you need to also add the request method.

@RequestMapping(method = RequestMethod.GET)
public String loginRoot() {
    return "login";
}

Consider using spring mvc tests to make the process of testing these scenarios easier:

Answer 3

Yes that is possible. The path in @RequestMapping on the method is relative to the path on the class annotation.

With your current setup, loginRoot() will handle requests to

localhost:8080/projectname/login/

Assuming you don't have anything else in your configuration preventing this.
