交友项目【集成环信Api】

1：自动装配

在项目中集成环信API，完成即时通信等

自动装配模块：

pom文件相关依赖

<dependency>
    <groupId>com.easemob.im</groupId>
    <artifactId>im-sdk-core</artifactId>
    <version>0.5.2</version>
</dependency>

yml文件中配置相关信息

huanxin:
  appkey: ****************
  clientId: ****************
  clientSecret: ****************

读取yml文件中的配置

@ConfigurationProperties(prefix = "tanhua.huanxin")
@Data
public class HuanXinProperties {

    private String appkey;
    private String clientId;
    private String clientSecret;

}

创建封装类以及需要用到的方法

package com.czxy.tanhua.autoconfig.template;

import cn.hutool.core.collection.CollUtil;
import com.alibaba.fastjson.JSON;
import com.czxy.tanhua.autoconfig.properties.HuanXinProperties;
import com.czxy.tanhua.autoconfig.vo.HuanxinMessageVo;
import com.easemob.im.server.EMProperties;
import com.easemob.im.server.EMService;
import com.easemob.im.server.model.EMTextMessage;
import lombok.extern.log4j.Log4j;

import java.util.Set;

@Log4j
public class HuanXinTemplate {
    private EMService service;

    public HuanXinTemplate(HuanXinProperties properties) {
        EMProperties emProperties = EMProperties.builder()
                .setAppkey(properties.getAppkey())
                .setClientId(properties.getClientId())
                .setClientSecret(properties.getClientSecret())
                .build();
        service = new EMService(emProperties);
    }

    /**
     * 创建环信用户
     * @param username
     * @param password
     * @return
     */
    public Boolean createUser(String username,String password) {
        try {
            //创建环信用户
            service.user().create(username.toLowerCase(), password)
                    .block();
            return true;
        }catch (Exception e) {
            e.printStackTrace();
            log.error("创建环信用户失败~");
        }
        return false;
    }

    /**
     * 添加联系人
     * @param username1
     * @param username2
     * @return
     */
    public Boolean addContact(String username1,String username2) {
        try {
            //创建环信用户
            service.contact().add(username1,username2)
                    .block();
            return true;
        }catch (Exception e) {
            log.error("添加联系人失败~");
        }
        return false;
    }

    /**
     * 删除联系人
     * @param username1
     * @param username2
     * @return
     */
    public Boolean deleteContact(String username1,String username2) {
        try {
            //创建环信用户
            service.contact().remove(username1,username2)
                    .block();
            return true;
        }catch (Exception e) {
            log.error("删除联系人失败~");
        }
        return false;
    }

    /**
     * 发送消息
     * @param username
     * @param huanxinMessageVo
     * @return
     */
    public Boolean sendMsg(String username, HuanxinMessageVo huanxinMessageVo) {
        try {
            //接收人用户列表
            Set<String> set = CollUtil.newHashSet(username);
            // 将消息内容转换成json
            String content = JSON.toJSONString(huanxinMessageVo);
            //文本消息
            EMTextMessage message = new EMTextMessage().text(content);
            //发送消息  from：admin是管理员发送
            service.message().send("admin","users",
                    set,message,null).block();
            return true;
        }catch (Exception e) {
            log.error("删除联系人失败~");
        }
        return false;
    }
}

在引导类中进行声明封装类，将相关的工具类交给IOC容器管理

/** 自动装配类
 * @description
 */
@EnableConfigurationProperties({
        SmsProperties.class,
        OssProperties.class,
        AipFaceProperties.class,
        HuanXinProperties.class
})
public class TanhuaAutoConfiguration {

    @Bean
    public SmsTemplate smsTemplate(SmsProperties smsProperties) {
        return new SmsTemplate(smsProperties);
    }

    @Bean
    public OssTemplate ossTemplate(OssProperties ossProperties) {
        return new OssTemplate(ossProperties);
    }

    @Bean
    public AipFaceTemplate aipFaceTemplate() {
        return new AipFaceTemplate();
    }

    @Bean
    public HuanXinTemplate huanXinTemplate(HuanXinProperties properties) {
        return new HuanXinTemplate(properties);
    }
}

在resources目录下创建META-INF文件夹，在此文件夹下创建spring.factories文件，该文件声明引导类位置，springboot启动时会加载该文件中声明的引导类完成工具类的自动装配。

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
  com.czxy.tanhua.autoconfig.TanhuaAutoConfiguration

2：查询用户环信账户

接口地址： http://192.168.136.160:3000/project/19/interface/api/85

app-server模块：

controller层：

@RestController
@RequestMapping("/huanxin")
public class HuanxinController {

    @Resource
    private UserService userService;

    @GetMapping("/user")
    public ResponseEntity<HuanXinUserVo> user() {
        HuanXinUserVo huanXinUserVo = userService.findHuanXinUser();
        return ResponseEntity.ok(huanXinUserVo);
    }
}

service层：

    public HuanXinUserVo findHuanXinUser() {
        // 查询
        User user = userApi.findById(UserHolder.getUserId());
        if(user == null) {
            return null;
        }
        // 封装
        return new HuanXinUserVo(user.getHxUser() ,user.getHxPassword());
    }

3：环信ID查询用户信息

app-server模块：

controller层

    @GetMapping("/userinfo")
    public ResponseEntity userinfo(String huanxinId) {
        //查询
        UserInfoVo userInfoVo = messageService.findUserInfoByHuanxin(huanxinId);
        //返回
        return ResponseEntity.ok(userInfoVo);
    }

service层：

    /**
     * 通过环信id查询详情
     * @param huanxinId
     * @return
     */
    public UserInfoVo findUserInfoByHuanxin(String huanxinId) {
        //1 通过huanxinId查询用户信息
        User user = userApi.findByHuanxin(huanxinId);

        //2 查询UserInfo信息
        UserInfo userInfo = userInfoApi.findById(user.getId());

        //3 封装数据UserInfoVo
        UserInfoVo userInfoVo = new UserInfoVo();
        BeanUtils.copyProperties(userInfo, userInfoVo);
        if(userInfo.getAge() != null){
            userInfoVo.setAge(userInfo.getAge().toString());
        }
        return userInfoVo;
    }

通过huanxinId查询用户信息的接口

    @Override
    public User findByHuanxin(String huanxinId) {
        QueryWrapper<User> queryWrapper = new QueryWrapper<>();
        queryWrapper.eq("hx_user", huanxinId);
        return userMapper.selectOne(queryWrapper);
    }

通过userid查询用户的接口

    @Override
    public UserInfo findById(Long userInfoId) {
        return userInfoMapper.selectById(userInfoId);
    }
