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。

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 findUserByParams(User user);
void createUser(User user);
void deleteUser(User user);
void batchDeleteUser(List userIds);
void updateUser(User user);
}
and user_id = #{userId}
and user_name = #{userName}
and age = #{age}
INSERT INTO t_user(user_name, age) VALUES (#{userName, jdbcType=VARCHAR}, #{age, jdbcType=INTEGER})
DELETE FROM t_user
DELETE FROM t_user
where user_id in
#{userId}
UPDATE t_user
user_name = #{userName, jdbcType=VARCHAR},
age = #{age, jdbcType=INTEGER},
where user_id = #{userId}
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 userIds);
void updateUser(User user);
}
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 userIds) {
userDao.batchDeleteUser(userIds);
}
@Override
public void updateUser(User user) {
userDao.updateUser(user);
}
} 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 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;
}
package com.wrpys.ssm.common;
import java.util.List;
/**
* @author wrp
* @Description com.wrpys.ssm.common.PageInfo
* @Date 2017/1/13
*/
public class PageInfo {
private Integer pageNumber;
private Integer pageSize;
private Long total;
private List 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 getRows() {
return rows;
}
public void setRows(List rows) {
this.rows = rows;
}
}
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。
