浏览器输入http://localhost:8081/dianping/index时，出现HTTP Status 404 – Not Found

Question

源生活老师，您好！

程序正常启动，http://localhost:8081/dianping会出现 Hello World!页面。

但是输入http://localhost:8081/dianping/index时，出现HTTP Status 404 – Not Found

controller代码如下：

@Controller
@RequestMapping("/index")
public class IndexController {
    public String init(){
        return "/system/index";
    }
}

我怀疑是不是我开发环境设置不正确？

打扰了，问题已经解决。

@Controller
@RequestMapping("/index")
public class IndexController {
    @RequestMapping
    public String init(){
        return "/system/index";
    }
}

第二个 @RequestMapping 忘记写了 笨啊
