1、通用设置

1.1 需求分析

1.1.1 需求分析

通用设置，包含探花交友APP基本的软件设置功能。包含：

设置陌生人问题：当平台其他用户想进行在线交流时需要回答陌生人问题。

通用设置：包含一些APP通知设置

黑名单：对于不感兴趣的用户设置黑名单屏蔽骚扰

1.2.2 代码实现

vo对象


@Data@NoArgsConstructor
@AllArgsConstructor
public class SettingsVo implements Serializable {

    private Long id;
    private String strangerQuestion = "";
    private String phone;
    private Boolean likeNotification = true;
    private Boolean pinglunNotification = true;
    private Boolean gonggaoNotification = true;

}


SettingsController

在​​tanhua-server​​​工程创建​​SettingsController​​完成代码编写


@RestController@RequestMapping("/users")
public class SettingsController {

    @Autowired
    private SettingsService settingsService;

    /**
     * 查询通用设置
     */
    @GetMapping("/settings")
    public ResponseEntity settings() {
        SettingsVo vo = settingsService.settings();
        return ResponseEntity.ok(vo);
    }
}


SettingService

在​​tanhua-server​​​工程创建​​SettingService​​完成代码编写


@Servicepublic class SettingsService {

    @DubboReference
    private QuestionApi questionApi;

    @DubboReference
    private SettingsApi settingsApi;

    @DubboReference
    private BlackListApi blackListApi;

    //查询通用设置
    public SettingsVo settings() {
        SettingsVo vo = new SettingsVo();
        //1、获取用户id
        Long userId = UserHolder.getUserId();
        vo.setId(userId);
        //2、获取用户的手机号码
        vo.setPhone(UserHolder.getMobile());
        //3、获取用户的陌生人问题
        Question question = questionApi.findByUserId(userId);
        String txt = question == null ? "你喜欢java吗？" : question.getTxt();
        vo.setStrangerQuestion(txt);
        //4、获取用户的APP通知开关数据
        Settings settings = settingsApi.findByUserId(userId);
        if(settings != null) {
            vo.setGonggaoNotification(settings.getGonggaoNotification());
            vo.setPinglunNotification(settings.getPinglunNotification());
            vo.setLikeNotification(settings.getLikeNotification());
        }
        return vo;
    }
}


QuestionApi

在tanhua-dubbo中的​​QuestionApi​​​和​​QuestionApiImpl​​补充方法


@Overridepublic Question findByUserId(Long userId) {
    QueryWrapper<Question> qw = new QueryWrapper<>();
    qw.eq("user_id",userId);
    return questionMapper.selectOne(qw);
}


SettingApi

    Question question = questionApi.findByUserId(userId);
    //3、判断问题是否存在
    if(question == null) {
        //3.1 如果不存在，保存
        question = new Question();
        question.setUserId(userId);
        question.setTxt(content);
        questionApi.save(question);
    }else {
        //3.2 如果存在，更新
        question.setTxt(content);

    if(settings == null) {
        //保存
        settings = new Settings();
        settings.setUserId(userId);
        settings.setPinglunNotification(pinglunNotification);
        settings.setLikeNotification(likeNotification);
        settings.setGonggaoNotification(gonggaoNotification);
        settingsApi.save(settings);
    }else {
        settings.setPinglunNotification(pinglunNotification);
        settings.setLikeNotification(likeNotification);

1.3.2 分页查询

vo对象

​​tanhua-domain​​工程的配置分页vo对象


package com.tanhua.domain.vo;import lombok.AllArgsConstructor;import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;
import java.util.Collections;
import java.util.List;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class PageResult implements Serializable {

    private Integer counts = 0;//总记录数
    private Integer pagesize;//页大小
    private Integer pages = 0;//总页数
    private Integer page;//当前页码
    private List<?> items = Collections.emptyList(); //列表

    public PageResult(Integer page,Integer pagesize,
                      int counts,List list) {
        this.page = page;
        this.pagesize = pagesize;
        this.items = list;
        this.counts = counts;
        this.pages = counts % pagesize == 0 ? counts / pagesize : counts / pagesize + 1;
    }

}


SettingsController


/** * 分页查询黑名单列表 */
@GetMapping("/blacklist")
public ResponseEntity blacklist(
        @RequestParam(defaultValue = "1") int page,
        @RequestParam(defaultValue = "10") int size) {
    //1、调用service查询
    PageResult pr = settingsService.blacklist(page,size);
    //2、构造返回
    return ResponseEntity.ok(pr);
}

/**
 * 取消黑名单
 */
@DeleteMapping("/blacklist/{uid}")
public ResponseEntity deleteBlackList(@PathVariable("uid") Long blackUserId) {
    settingsService.deleteBlackList(blackUserId);
    return ResponseEntity.ok(null);
}


SettingService


//分页查询黑名单列表public PageResult blacklist(int page, int size) {    //1、获取当前用户的id
    Long userId = UserHolder.getUserId();
    //2、调用API查询用户的黑名单分页列表  Ipage对象
    IPage<UserInfo> iPage = blackListApi.findByUserId(userId,page,size);
    //3、对象转化，将查询的Ipage对象的内容封装到PageResult中
    PageResult pr = new PageResult(page,size,iPage.getTotal(),iPage.getRecords());
    //4、返回
    return pr;
}

//取消黑名单
public void deleteBlackList(Long blackUserId) {
    //1、获取当前用户id
    Long userId = UserHolder.getUserId();
    //2、调用api删除
    blackListApi.delete(userId,blackUserId);
}


BlackListApi


@Overridepublic IPage<UserInfo> findByUserId(Long userId, int page, int size) {    //1、构建分页参数对象Page
    Page pages = new Page(page,size);
    //2、调用方法分页（自定义编写 分页参数Page，sql条件参数）
    return userInfoMapper.findBlackList(pages,userId);
}

@Override
public void delete(Long userId, Long blackUserId) {
    QueryWrapper<BlackList> qw = new QueryWrapper<>();
    qw.eq("user_id",userId);
    qw.eq("black_user_id",blackUserId);
    blackListMapper.delete(qw);
}


UserInfoMapper


public interface UserInfoMapper extends BaseMapper<UserInfo> {    @Select("select * from tb_user_info where id in (\n" +            "  SELECT black_user_id FROM tb_black_list where user_id=#{userId}\n" +
            ")")
    IPage<UserInfo> findBlackList(@Param("pages") Page pages, @Param("userId") Long userId);
}


MybatisPlusConfig

​​tanhua-dubbo-db​​引导类开启mybatis-plus分页插件支持


@Beanpublic MybatisPlusInterceptor mybatisPlusInterceptor() {    MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
    interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.MYSQL));
    return interceptor;
}


使用mybatis-plus的分页：

  • 创建分页对象：Page，指定当前页和每页查询条数
  • 基础查询：mapper.selectPage(page,查询条件)
  • 自定义查询：Ipage 方法名称（Page对象，xxx查询条件）
