(二) ssm -- spring-mvc.xml

spring-mvc.xml 代码

web.xml 代码

        xmlns="http://java.sun.com/xml/ns/javaee"

</web-app>

配置完成后 创一个controller 测试

package com.taotao.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class Test {
    
    @RequestMapping("/index.do")
    public String test(){
        System.out.println("测试。。。。。。。。。。。。");
        return "index";
    }
}

注意 jsp 文件在webapp/views 里
