后台用户管理功能设计（个人博客）

后台用户管理功能设计（个人博客）

1、编写dao层

@Mapper
public interface UserMapper {
    @Select("select * from user where username=#{username}")
    User getByName(String username);

    @Update("update user set password = #{password},nickname = #{nickname},avatar = #{avatar}" +
            "where id = #{id}")
    int updateUser(User user);

    int deleteByPrimaryKey(Long id);

    int insert(User record);
    
    List<User> selectAll();

}

2、编写绑定配置文件

<?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.pang.dao.UserMapper" >
  <resultMap id="BaseResultMap" type="user" >
    <id column="id" property="id"/>
    <result column="username" property="username"/>
    <result column="password" property="password"/>
    <result column="nickname" property="nickname"/>
    <result column="avatar" property="avatar"/>
  </resultMap>
  <delete id="deleteByPrimaryKey" parameterType="java.lang.Long" >
    delete from user
    where id = #{id}
  </delete>
  <insert id="insert" parameterType="user" >
    <selectKey resultType="java.lang.Long" keyProperty="id" order="AFTER" >
      SELECT LAST_INSERT_ID()
    </selectKey>
    insert into user (username, password, nickname, 
      avatar)
    values (#{username}, #{password}, #{nickname}, 
      #{avatar})
  </insert>
  <update id="updateByPrimaryKey" parameterType="user" >
    update user
    set username = #{username},
      password = #{password},
      nickname = #{nickname},
      avatar = #{avatar}
    where id = #{id}
  </update>
  <select id="selectByPrimaryKey" resultMap="BaseResultMap" parameterType="java.lang.Long" >
    select id, username, password, nickname, avatar
    from user
    where id = #{id}
  </select>
  <select id="selectAll" resultMap="BaseResultMap" >
    select id, username, password, nickname, avatar
    from user
  </select>
  <select id="login" resultMap="BaseResultMap" >
    select id, username, password, nickname, avatar
    from user
    where username = #{username}
    and password = #{password}
  </select>
</mapper>

3、编写service层

@Service
public class UserService {

    @Autowired
    private UserMapper userMapper;

    public List<User> selectAll() {
        return userMapper.selectAll();
    }
    public int updateUser(User user) {
        return userMapper.updateUser(user);
    }
    public User getByName(String username){
        return userMapper.getByName(username);
    }
    public int deleteUser(Long id){
        return userMapper.deleteByPrimaryKey(id);
    }
}

4、编写controller层

	@RequestMapping("/toUpdUser")
    public String toUpdateUser(Principal principal, Model model){
        User user = userService.getByName(principal.getName());
        model.addAttribute("user",user);
        return "admin/users-update";
    }

    @RequestMapping("/admin/updUser")
    public String updUser(User user){
        userService.updateUser(user);
        return "redirect:/logout";
    }

    @RequestMapping("/admin/deleteUser/{id}")
    public String deleteUser(@PathVariable("id") Long id){
        userService.deleteUser(id);
        return "redirect:/admin/toUser";
    }

5、绑定前端页面

 		<table class="ui celled table">
            <thead>
            <tr>
                <th>编号</th>
                <th>用户名</th>
                <th>个性名称</th>
                <th>头像链接</th>
                <th>操作</th>
            </tr>
            </thead>
            <tbody>
            <tr th:each="user:${pageInfo.list}">
                <td th:text="${user.id}"></td>
                <td th:text="${user.username}"></td>
                <td th:text="${user.nickname}"></td>
                <td th:text="${user.avatar}"></td>
                <td>
                    <a th:href="@{/admin/deleteUser/{id}(id=${user.id})}" class="ui mini red basic button">删除</a>
                </td>
            </tr>
            </tbody>
            <tfoot>
            <tr>
                <th colspan="6">
                    <div class="ui mini pagination menu">
                        <a class="icon item" th:href="@{/admin/toUser(pageNum=${pageInfo.hasPreviousPage}?${pageInfo.prePage}:1)}" th:unless="${pageInfo.isFirstPage}">上一页</a>
                        <a class="icon item" th:href="@{/admin/toUser(pageNum=${pageInfo.hasNextPage}?${pageInfo.nextPage}:${pageInfo.pages})}" th:unless="${pageInfo.isLastPage}">下一页</a>
                    </div>
                </th>
            </tr>
            </tfoot>
        </table>
