### 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![a30ab413f6ad494f825bde929a4f5e42.png][]

1.2.1 接口文档

![66198f49df7a46dfaaf4af75df35668f.png][]

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

@Service
    public 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

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

SettingApi

在tanhua-dubbo中的`SettingApi`和`SettingApiImpl`补充方法

//根据用户id查询
    public Settings findByUserId(Long userId) {
        QueryWrapper<Settings> qw = new QueryWrapper<>();
        qw.eq("user_id",userId);
        return settingsMapper.selectOne(qw);
    }

#### 1.2 陌生人问题 ####

对数据库表进行操作：如果存在数据，更新数据库。如果不存在数据，保存数据库表数据

1.2.1 接口文档

![a2f9be76a66d4cc4971c39e1ae30d009.png][]

1.2.2 代码实现

SettingsController

/**
     * 设置陌生人问题
     */
    @PostMapping("/questions")
    public ResponseEntity questions(@RequestBody Map map) {
        //获取参数
        String content = (String) map.get("content");
        settingsService.saveQuestion(content);
        return ResponseEntity.ok(null);
    }

SettingsService

//设置陌生人问题
    public void saveQuestion(String content) {
        //1、获取当前用户id
        Long userId = UserHolder.getUserId();
        //2、调用api查询当前用户的陌生人问题
        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);
            questionApi.update(question);
        }
    }

QuestionApi

`tanhua-dubbo`工程中的`QuestionApi`和`QuestionApiImpl`中添加保存和更新方法

@Override
    public void save(Question question) {
        questionMapper.insert(question);
    }
    
    @Override
    public void update(Question question) {
        questionMapper.updateById(question);
    }

        boolean pinglunNotification = (Boolean) map.get("pinglunNotification");
        boolean gonggaoNotification = (Boolean)  map.get("gonggaoNotification");
        //1、获取当前用户id
        Long userId = UserHolder.getUserId();
        //2、根据用户id，查询用户的通知设置
        Settings settings = settingsApi.findByUserId(userId);
        //3、判断
        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);
            settings.setGonggaoNotification(gonggaoNotification);
            settingsApi.update(settings);
        }
    }

SettingsApi

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

@Override
    public 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

@Bean
    public 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）
