SpringMVC访问不到路径

[艾比利夫]

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping(value="/add")
    @ResponseBody
    public String addUser(HttpServletRequest request,User user) {
        userService.addUser(user);
        request.setAttribute("user",user);
        return "hello";
    }
}

访问localhost:8080/user/add 报404 新人初学 求教

[lewis219]

localhost:8080/工程名称/user/add 试试

[S117]

你的路径少了工程名

学习了

还是不行啊 后台tomcat报这个 2014-05-23 11:15:40 040 [] [DEBUG] org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:843) - DispatcherServlet with name 'dispatcher' processing GET request for [/ifr_status/] 2014-05-23 11:15:40 040 [] [WARN] org.springframework.web.servlet.DispatcherServlet.noHandlerFound(DispatcherServlet.java:1118) - No mapping found for HTTP request with URI [/ifr_status/] in DispatcherServlet with name 'dispatcher' 2014-05-23 11:15:40 040 [] [DEBUG] org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:991) - Successfully completed request 2014-05-23 11:15:42 042 [] [DEBUG] org.springframework.web.servlet.DispatcherServlet.doService(DispatcherServlet.java:843) - DispatcherServlet with name 'dispatcher' processing GET request for [/user/add] 2014-05-23 11:15:42 042 [] [WARN] org.springframework.web.servlet.DispatcherServlet.noHandlerFound(DispatcherServlet.java:1118) - No mapping found for HTTP request with URI [/user/add] in DispatcherServlet with name 'dispatcher' 2014-05-23 11:15:42 042 [] [DEBUG] org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:991) - Successfully completed request

类不需要加@requestMapping()注解吧。 方法上面加注解，应该是这样子的吧@RequestMapping("/xxx.do")

Controller可以加@requestMapping()注解的，表示这个控制器里面的方法前面都+这个/user

[疯狂的玖号]

看看你的web.xml

我刚才试验了一下 注释掉

<!--配置spirngMVC-web的静态资源，不配会当成控制器-->
    <mvc:resources mapping="/assets/**" location="assets/"/>
    <mvc:resources mapping="/codefans.net/**" location="codefans.net/"/>
    <mvc:resources mapping="/Css/**" location="Css/"/>
    <mvc:resources mapping="/font/**" location="codefans.net/"/>
    <mvc:resources mapping="/Images/**" location="Images/"/>
    <mvc:resources mapping="/Js/**" location="Js/"/>
    <mvc:resources mapping="/Menu/**" location="Menu/"/>
    <mvc:resources mapping="/Node/**" location="Node/"/>
    <mvc:resources mapping="/pages/**" location="pages/"/>
    <mvc:resources mapping="/Public/**" location="Public/"/>
    <mvc:resources mapping="/Role/**" location="Role/"/>
    <mvc:resources mapping="/User/**" location="User/"/>

注释掉这一部分就可以了。。。但不知道原因

[一路记忆]

我也碰到过这个问题，在web.xml添加 <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>/resources/*</url-pattern> </servlet-mapping> 里面配置这个，替代spring配置文件里的 <mvc:resources mapping="" location=""/> 就可以解决。

[铁铲]

原因：<mvc:resources mapping="/assets/**" location="assets/"/> 这些导致 @Controller失效 所以报404 解决：加上<mvc:annotation-driven />就没有问题了 或者像楼上说的也许

[imdongrui]

<mvc:annotation-driven />不是表示mvc使用注解进行配置么，如果不配置这个的话，你在Controller里写的那些注解都无效，它应该是默认使用xml进行配置的
