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

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

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。 新增： ![20170118000944136][] ![20170118001020958][] 修改： ![20170118001150983][] ![20170118001234677][] 分页查询： 测试数据： ![20170118001639585][] 结果： ![20170118001729255][] ![20170118001817851][] 删除： ![20170118001925867][] ![20170118001929476][] 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。 源码地址：http://pan.baidu.com/s/1eSEAsuu [20170117234308209]: /images/20220610/eac98da67b9d47e49670f011fbd1c783.png
