java - Spring MVC : RequestMapping both class and method

Question

这可能吗？

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

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

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

}

访问 localhost:8080/projectname/login 时出现 404 错误，但在 localhost:8080/projectname/login/error 中却没有。

这是我的 web.xml 项目名称

<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>

您不需要方法映射中的 /。只需将其映射到 "".
