java - SpringMVC : No mapping found for HTTP request

Question

请查看我的控制台中记录的第一行和最后一行。第一行声明 /SpringMVC/welcome 映射到 helloController 但日志中的最后一行显示其他情况!

背景:我直接从 MyKong 获取源代码并试图逃跑。除了将 @RequestMapping("/welcome") 更改为 @RequestMapping("/SpringMVC/welcome") 之外，我没有更改任何配置。提供完整源代码here

Controller 代码:

package com.mkyong.common.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

@Controller
@RequestMapping("/SpringMVC/welcome")
public class HelloController {

    @RequestMapping(method = RequestMethod.GET)
    public String printWelcome(ModelMap model) {

        model.addAttribute("message", "Spring 3 MVC Hello World");
        return "hello";

    }

}

Answer 1

是的。您的 Controller 方法已映射到

/SpringMVC/welcome

相对于您的上下文路径。

也就是说，如果您的上下文路径是

/SpringMVC

，那么请求需要发送到

/SpringMVC/SpringMVC/welcome
