SSM 入门案例：

基于我们配置好了SSM环境后，

1、编写请求端：

<html>
<body>
<h2>Hello World!</h2>
<a href="<%=request.getContextPath()%>/account/login.do?id=1&name=zhangsan"> delete </a>
</body>
</html>

编写controller：

package com.xingxue.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.xingxue.service.UserService;

@Controller
@RequestMapping(“/user”)
public class UserContrller {

@Autowired
public UserService service;

@RequestMapping("/delete.do")
public String delete(int id){
    this.service.delete(id);

    return null;
}

public String login(String account, String pwd){

    this.service.login(account,pwd);
    return null;
}

}

编写service
package com.xingxue.service.impl;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.xingxue.dao.UserMapper;
import com.xingxue.service.UserService;

@Service(“service”)
public class UserServiceImpl implements UserService{

@Autowired
public UserMapper mapper;
@Override
public void delete(int id) {

    this.mapper.deleteByPrimaryKey(id);

}
@Override
public void login(String account, String pwd) {

    this.mapper.login(account, pwd);

}

}

利用mybatis逆向工程生成mapper、dao、实体类然后导入项目

这里写图片描述
然后运行即可
