基于Maven搭建ssm项目

1  新建Maven工程（不在这描述）

2  修改pom.xml配置文件如下

配置环境就搭建完成了以下是目录结构：

             

６　编写controller 完成测试

package com.m.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class UserController {
	@RequestMapping("/hello")
	@ResponseBody // responseBody 返回字符串 去掉此注解  根据返回值 跳转到想应的页面
	public String say(){
		return "hello";
	}	
}

7 在页面输入http://localhost:8080/manager/hello完成环境搭建测试

8 修改UserController类如下：

package com.m.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class UserController {
	@RequestMapping("/hello")
	public String say(){
		return "hello";
	}	
}

9 界面运行如下：跳转到hello.jsp

至此ssm环境搭建就完成了，下篇完成前端的数据交互
