2. 编写配置文件
代码语言：javascript
复制# 服务器
server.port=8081
#json的时间格式:
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
#模板引擎
spring.thymeleaf.mode=HTML5
spring.thymeleaf.cache=false
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.encoding=UTF-8
# 静态资源的释放
spring.mvc.static-path-pattern=/static/**
#文件上传的大小
spring.servlet.multipart.max-file-size=2MB
# 定义 加载 开发环境下的 配置文件
#spring.profiles.active=dev
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/job?useUnicode=true&characterEncoding=utf-8&serverTimeZone=GMT
spring.datasource.username=root
spring.datasource.password=sorry
mybatis.mapper-locations=classpath:/cn/javabs/job/mapper/*.xml
#pagehelper分页插件配置
pagehelper.helperDialect=mysql
pagehelper.reasonable=true
pagehelper.supportMethodsArguments=true
pagehelper.params=count=countSql
pagehelper.pageSize = 10
#热部署
spring.devtools.restart.enabled=true
3. 编写实体类
代码语言：javascript
复制package cn.javabs.job.entity;
import lombok.Data;
/**
* 用户实体类设计
* 1. 应聘者: 学生
* 2. 招聘者: 公司人力资源
*/
@Data
public class User {
// -----------------定义常量:--------------------
final int USER_SEX_MAN = 1; // 性别 男
final int USER_SEX_WOMAN = 2; // 性别 女
final int USER_SEX_UNKONW = 0; // 性别 未知
final String DEFAULT_HEAD_IMGAE = "common/default_img.jpg"; // 默认的用户头像
final String DEFAULT_WORK_EXP = "应届毕业生"; // 默认是应届毕业生
final String DEFAULT_DEGREE = "其他"; // 默认是其他、专科、本科、研究生
// -----------------变量:--------------------
private int userId;
private String username; // 用户名
private String password;// 密码
private String email;// 邮箱地址
private String headPic = DEFAULT_HEAD_IMGAE; // 用户头像
private String workExp = DEFAULT_WORK_EXP; // 工作经验，默认是应届毕业生
private String degree = DEFAULT_DEGREE; // 学历，默认是其他
private int sex = USER_SEX_UNKONW ;// 用户性别 默认是未知
private int type ; // 用户类别， 0-学生（应聘者）；1-（公司的HR）招聘者
private String mobile ; // 手机号码
private String selfDescription ; // 自我描述
}
4. 编写数据持久层接口
代码语言：javascript
复制package cn.javabs.job.mapper;
import cn.javabs.job.entity.User;
import org.springframework.stereotype.Repository;
import java.util.List;
@Repository("userMapper")
public interface UserMapper {
/**
* 后端获取所有用户的信息
* @return 返回的集合
*/
List<User> findAllUserList();
/**
* 按照邮箱查询用户的信息
* @param email
* @return 返回的对象
*/
User findUserByEmail(String email);
/**
* 按照条件(用户名或者性别或者学历)查询用户信息 返回的集合
* @param condition
* @return
*/
List<User> findUserByCondition(String condition);
/**
* 按照用户id查询用户信息
* @param userId
* @return 返回的对象
*/
User findUserByUserId(int userId);
/**
* 用户登录
* 根据用户名和密码及用户类型执行 登录
* @param user
* @return
*/
User login(User user);
int addUser(User user);
int delUser(int userId);
int editUser(User user);
}
5. 编写持久层映射文件

6. 编写业务逻辑层接口
代码语言：javascript
复制package cn.javabs.job.service;
import cn.javabs.job.entity.User;
import java.util.List;
public interface UserService {
List<User> getAllUserList();
User getUserByEmail(String email);
User getUserByUserId(int userId);
List<User> getUserByCondition(String condition);
User userLogin(User user);
int deleteUser(int userId);
int editUser(User user);
int addUser(User user);
}
7. 编写业务逻辑层接口的实现类
代码语言：javascript
复制package cn.javabs.job.service.impl;
import cn.javabs.job.entity.User;
import cn.javabs.job.mapper.UserMapper;
import cn.javabs.job.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import javax.annotation.Resource;
import java.util.List;
@Service("userService")
@Transactional
public class UserServiceImpl implements UserService {
@Resource
@Qualifier("userMapper")
private UserMapper userMapper;
@Override
public List<User> getAllUserList() {
return userMapper.findAllUserList();
}
@Override
public User getUserByEmail(String email) {
return userMapper.findUserByEmail(email);
}
@Override
public User getUserByUserId(int userId) {
return userMapper.findUserByUserId(userId);
}
@Override
public List<User> getUserByCondition(String condition) {
return userMapper.findUserByCondition(condition);
}
@Override
public User userLogin(User user) {
return userMapper.login(user);
}
@Override
public int deleteUser(int userId) {
return userMapper.delUser(userId);
}
@Override
public int editUser(User user) {
return userMapper.editUser(user);
}
@Override
public int addUser(User user) {
return userMapper.addUser(user);
}
}
8. 编写控制器类
代码语言：javascript
复制package cn.javabs.job.controller;
import cn.javabs.job.entity.User;
import cn.javabs.job.service.UserService;
import com.github.pagehelper.PageHelper;
import com.github.pagehelper.PageInfo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import javax.annotation.Resource;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
/**
* 后端用户管理的控制器
*/
@Controller
@RequestMapping("/admin/user")
public class UserController {
@Resource
@Qualifier("userService")
private UserService userService;
@Value("${pagehelper.pageSize}")
private int pageSize;
@RequestMapping("userList")
public ModelAndView userList(@RequestParam(value = "pageNum",defaultValue = "1") Integer pageNum){
PageHelper.startPage(pageNum,pageSize);
List<User> userList = userService.getAllUserList();
PageInfo<User> pageInfo = new PageInfo<>(userList);
ModelAndView mv = new ModelAndView();
mv.addObject("userList",userList);
mv.addObject("pageInfo",pageInfo);
mv.setViewName("user");
return mv;
}
}
9. 编写页面，模板引擎
代码语言：javascript
复制<!DOCTYPE html>
