import java.util.HashMap;
import java.util.Map;

public class Message {
private Integer code ;// 状态码 200 代表成功 500 代表失败
private String msg ;
private Map maps = new HashMap() ;

/**
 * 成功
 * @return
 */
public static Message success() {
    Message message = new Message() ;
    message.setCode(200);
    message.setMsg("成功");
    return message ;
}

/**
 * 失败
 * @return
 */
public static Message error() {
    Message message = new Message() ;
    message.setCode(500);
    message.setMsg("失败");
    return message;
}

/**
 *
 * @param key
 * @param value
 * @return
 */
public Message add(String key,Object value) {
    this.getMaps().put(key,value);
    return this;
}

public Integer getCode() {
    return code;
}

public void setCode(Integer code) {
    this.code = code;
}

public String getMsg() {
    return msg;
}

public void setMsg(String msg) {
    this.msg = msg;
}

public Map getMaps() {
    return maps;
}

public void setMaps(Map maps) {
    this.maps = maps;
}

}

2.编写控制器
package com.edu.controller;

import com.edu.bean.Customer;
import com.edu.bean.Message;
import com.edu.service.CustomerService;
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;

/**

• 这是用户controller*/
  @Controller
  br/>*/
  @Controller
  public class CustomerController {@Autowired
  br/>@Autowired
  private CustomerService customerService;

  /**

  • 用户登录的控制器
  • @param customer
  • @return*/
    @ResponseBody
    br/>*/
    @ResponseBody
    @RequestMapping("/login")
    public Message login(Customer customer) {
    Customer cust = customerService.loginByUserNameAndPwd(customer.getUserName(),customer.getUserPwd());
    if(null == cust) {
    return Message.error();
    }
    return Message.success();
    }

  /**

  • 用户注册的控制器
  • @param customer
  • @return*/
    @ResponseBody
    br/>*/
    @ResponseBody
    @RequestMapping("/reg")
    public Message reg(Customer customer) {
    try {
    customerService.save(customer);
    return Message.success();
    } catch (Exception e) {
    e.printStackTrace();
    return Message.error();
    }
    }
    }

3.编写service
package com.edu.service;

import com.edu.bean.Customer;

public interface CustomerService {
// 用户登录
Customer loginByUserNameAndPwd(String userName, String userPwd);
// 用户注册
void save(Customer customer);
}
4.编写service的实现类
package com.edu.service.impl;

import com.edu.bean.Customer;
import com.edu.bean.CustomerExample;
import com.edu.mapper.CustomerMapper;
import com.edu.service.CustomerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import java.util.List;

@Service@Transactional
br/>@Transactional
public class CustomerServiceImpl implements CustomerService {@Autowired
br/>@Autowired
private CustomerMapper customerMapper;@Override
br/>@Override
public Customer loginByUserNameAndPwd(String userName, String userPwd) {
CustomerExample example = new CustomerExample() ;
example.createCriteria().andUserNameEqualTo(userName).andUserPwdEqualTo(userPwd);
List customers = customerMapper.selectByExample(example);
if(customers.size()>0) {
return customers.get(0) ;
}
return null;
}

@Override
public void save(Customer customer) {
    customerMapper.insertSelective(customer);
}

}

5.编写mapper
使用反向引擎生成的mapper
6.编写页面

ssm+easyui+bootstrap+ajax 完成用户的登录和注册
