一步一步带你搭建后台管理系统之SSM框架整合

一步一步带你搭建后台管理系统之SSM框架整合README：本文后端采用 SpringMvc、MyBatis、Spring由于mybatis最新包对pagehelper会有错误，所以本文未采用最新的依赖。

到此SSM框架整合完毕。接下来新建一张表进行基本增删改查的测试。
用户表（t_user）：

CREATE TABLE `t_user` (
`user_id` bigint(20) NOT NULL AUTO_INCREMENT,
`user_name` varchar(64) DEFAULT NULL,
`age` int(11) DEFAULT NULL,
PRIMARY KEY (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=18 DEFAULT CHARSET=utf8;

在model包下新建类实体类User：

package com.wrpys.ssm.model;

/**
* @author wrp
* @Description com.wrpys.ssm.model.User
* @Date 2017/1/13
*/
public class User {

private Integer userId;

private String userName;

private Integer age;

public Integer getUserId() {
return userId;
}

public void setUserId(Integer userId) {
this.userId = userId;
}

public String getUserName() {
return userName;
}

public void setUserName(String userName) {
this.userName = userName;
}

public Integer getAge() {
return age;
}

public void setAge(Integer age) {
this.age = age;
}
}

在dao包下新建接口UserDao;

package com.wrpys.ssm.dao;

import com.wrpys.ssm.model.User;

import java.util.List;

/**
* @author wrp
* @Description com.wrpys.ssm.dao.UserDao
* @Date 2017/1/13
*/
public interface UserDao {

List<User> findUserByParams(User user);

void createUser(User user);

void deleteUser(User user);

void batchDeleteUser(List<Integer> userIds);

void updateUser(User user);

}

在model.mybatis包下新建mapper文件User.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.wrpys.ssm.dao.UserDao" >

<sql id="inc_whereClause" >
<where>
<if test="userId!=null">
and user_id = #{userId}
</if>
<if test="userName!=null and userName!=''">
and user_name = #{userName}
</if>
<if test="age!=null">
and age = #{age}
</if>
</where>
</sql>

<insert id="createUser">
INSERT INTO t_user(user_name, age) VALUES (#{userName, jdbcType=VARCHAR}, #{age, jdbcType=INTEGER})
</insert>

<delete id="deleteUser">
DELETE FROM t_user
<include refid="inc_whereClause"/>
</delete>

<delete id="batchDeleteUser">
DELETE FROM t_user
where user_id in
<foreach collection="list" item="userId" open="(" close=")" separator=",">
#{userId}
</foreach>
</delete>

<update id="updateUser">
UPDATE t_user
<set>
<if test="userName!=null">
user_name = #{userName, jdbcType=VARCHAR},
</if>
<if test="age!=null">
age = #{age, jdbcType=INTEGER},
</if>
</set>
where user_id = #{userId}
</update>

<select id="findUserByParams" resultType="com.wrpys.ssm.model.User">
SELECT user_id as userId, user_name as userName, age as age
from t_user
<include refid="inc_whereClause"/>
</select>

</mapper>

在service新建接口UserService：

package com.wrpys.ssm.service;

import com.wrpys.ssm.common.PageInfo;
import com.wrpys.ssm.model.User;

import java.util.List;

/**
* @author wrp
* @Description com.wrpys.ssm.service.UserService
* @Date 2017/1/13
*/
public interface UserService {

void findUser(PageInfo pageInfo, User user);

void createUser(User user);

void deleteUser(User user);

void batchDeleteUser(List<Integer> userIds);

void updateUser(User user);

}

在service.impl包下新建类UserServiceImpl：

package com.wrpys.ssm.service.impl;

import com.alibaba.fastjson.JSON;
import com.github.pagehelper.Page;
import com.github.pagehelper.PageHelper;
import com.wrpys.ssm.common.PageInfo;
import com.wrpys.ssm.dao.UserDao;
import com.wrpys.ssm.model.User;
import com.wrpys.ssm.service.UserService;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
* @author wrp
* @Description com.wrpys.ssm.service.impl.UserServiceImpl
* @Date 2017/1/13
*/
@Service
public class UserServiceImpl implements UserService {

Log logger = LogFactory.getLog(UserServiceImpl.class);

@Autowired
private UserDao userDao;

@Override
public void findUser(PageInfo pageInfo, User user) {
logger.info("findUser pageInfo:"+ JSON.toJSONString(pageInfo));
Page<?> page = PageHelper.startPage(pageInfo.getPageNumber(), pageInfo.getPageSize());
pageInfo.setRows(userDao.findUserByParams(user));
pageInfo.setTotal(page.getTotal());
}

@Override
public void createUser(User user) {
userDao.createUser(user);
}

@Override
public void deleteUser(User user) {
userDao.deleteUser(user);
}

@Override
public void batchDeleteUser(List<Integer> userIds) {
userDao.batchDeleteUser(userIds);
}

@Override
public void updateUser(User user) {
userDao.updateUser(user);
}

}

在ctroller包下先建类UserCtr：

package com.wrpys.ssm.controller;

import com.wrpys.ssm.common.Constans;
import com.wrpys.ssm.common.PageInfo;
import com.wrpys.ssm.common.ResultBean;
import com.wrpys.ssm.model.User;
import com.wrpys.ssm.service.UserService;
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.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import java.util.List;

/**
* @author wrp
* @Description com.wrpys.ssm.controller.UserCtr
* @Date 2017/1/13
*/
@Controller
@RequestMapping(value = "user")
public class UserCtr {

@Autowired
private UserService userService;

@RequestMapping(value = "list", method = {RequestMethod.GET, RequestMethod.POST})
@ResponseBody
public PageInfo findUser(PageInfo pageInfo, User user) {
userService.findUser(pageInfo, user);
return pageInfo;
}

@RequestMapping(value = "add", method = {RequestMethod.GET, RequestMethod.POST})
@ResponseBody
public ResultBean add(User user) {
ResultBean rb = new ResultBean();
userService.createUser(user);
rb.setFlag(Constans.SUCCESS);
return rb;
}

@RequestMapping(value = "delete", method = {RequestMethod.GET, RequestMethod.POST})
@ResponseBody
public ResultBean delete(User user) {
ResultBean rb = new ResultBean();
userService.deleteUser(user);
rb.setFlag(Constans.SUCCESS);
return rb;
}

@RequestMapping(value = "batchDeleteUser", method = {RequestMethod.GET, RequestMethod.POST})
@ResponseBody
public ResultBean batchDeleteUser(@RequestParam(value = "userIds") List<Integer> userIds) {
ResultBean rb = new ResultBean();
userService.batchDeleteUser(userIds);
rb.setFlag(Constans.SUCCESS);
return rb;
}

@RequestMapping(value = "update", method = {RequestMethod.GET, RequestMethod.POST})
@ResponseBody
public ResultBean update(User user) {
ResultBean rb = new ResultBean();
userService.updateUser(user);
rb.setFlag(Constans.SUCCESS);
return rb;
}

}

用到的一些公共类：
静态变量Constans：

package com.wrpys.ssm.common;

/**
* @author wrp
* @Description com.wrpys.ssm.common.Common
* @Date 2017/1/16
*/
public class Constans {

public final static Integer SUCCESS = 1;
public final static Integer FAIL = 0;

}

分页信息PageInfo：

package com.wrpys.ssm.common;

import java.util.List;

/**
* @author wrp
* @Description com.wrpys.ssm.common.PageInfo
* @Date 2017/1/13
*/
public class PageInfo<T> {

private Integer pageNumber;

private Integer pageSize;

private Long total;

private List<T> rows;

public Integer getPageNumber() {
return pageNumber;
}

public void setPageNumber(Integer pageNumber) {
this.pageNumber = pageNumber;
}

public Integer getPageSize() {
return pageSize;
}

public void setPageSize(Integer pageSize) {
this.pageSize = pageSize;
}

public Long getTotal() {
return total;
}

public void setTotal(Long total) {
this.total = total;
}

public List<T> getRows() {
return rows;
}

public void setRows(List<T> rows) {
this.rows = rows;
}
}

返回结果ResultBean：

package com.wrpys.ssm.common;

/**
* @author wrp
* @Description com.wrpys.ssm.common.ResultBean
* @Date 2017/1/16
*/
public class ResultBean {

private Integer flag;

private String msg;

private Object data;

public Integer getFlag() {
return flag;
}

public void setFlag(Integer flag) {
this.flag = flag;
}

public String getMsg() {
return msg;
}

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

public Object getData() {
return data;
}

public void setData(Object data) {
this.data = data;
}
}

到此t_user表的基本操作已经写完，启动项目，进行测试。

到此对增删改查的接口测试完毕。后端的SSM框架搭建完成。过程可能会出现各种个样的报错，希望耐心查询资料或者留言，有时间会过来帮忙解答。接下来篇章将进行前端插件的引入及其封装。
