eladmin仿微信pc聊天实现后台聊天（java后台）及数据库

之前做了前端得版本，今天正好把后端也放上，明后天还会开发点击查询后可以多人添加群聊还有一些辅助功能。

Controller

/**
* <p>
* 聊天
* </p>
*
* @author 啦啦
* @since 2023-02-22
*/
@Api(tags = "仿微信聊天")
@ApiSupport(order = 1, author = "啦啦")
@ApiRestController("weChatChat")
@RequiredArgsConstructor
public class ClientController extends BaseController{

    private final ClientService clientService;

    @GetMapping("/insertSendOut/{imputOn}")
    @ApiOperation(value = "聊天-新增", tags = ApiVersion.VERSION_1_0_0)
    public ResultWrapper<Integer> insertSendOut(@PathVariable String imputOn){
        return ResultWrapper.ok(clientService.insertSendOut(imputOn));
    }

    @GetMapping("/getSendOut")
    @ApiOperation(value = "聊天-查询", tags = ApiVersion.VERSION_1_0_0)
    public ResultWrapper<List<ClientVO>> getSendOut(){
        return ResultWrapper.ok(clientService.getSendOut());
    }

    @GetMapping("/getUserId")
    @ApiOperation(value = "聊天-查询当前用户返回用户id", tags = ApiVersion.VERSION_1_0_0)
    public ResultWrapper<String> getUserId(){
        return ResultWrapper.ok(clientService.getUserId());
    }


}

Service

/**
* <p>
* 仿微信聊天 服务实现类
* </p>
*
* @author guoliang
* @since 2022-04-03
*/
@Service
@RequiredArgsConstructor
public class ClientService extends MyServiceImpl<ContractMapper, ContractDO> {

    private final ClientMapper clientMapper;

    /**
     * <p>
     * 聊天-新增
     * </p>
     *
     */
    public int insertSendOut( String imputOn ) {
        Date date = new Date();
        SimpleDateFormat dateFormat= new SimpleDateFormat("yyyy-MM-dd :hh:mm:ss");
        String data = dateFormat.format(date);
        return clientMapper.insertSendOut( SecurityUtils.getCurrentUserId(), imputOn, data );
    }

    /**
     * <p>
     * 聊天-查询
     * </p>
     *
     */
    public List<ClientVO> getSendOut( ) {
        return clientMapper.getSendOut();
    }

    /**
     * <p>
     * 返回当前用户id
     * </p>
     *
     */
    public String getUserId( ) {
        return String.valueOf(SecurityUtils.getCurrentUserId());
    }


}

Mapper

/**
* <p>
* 仿微信聊天
* </p>
*
* @author guoliang
* @since 2022-04-03
*/
public interface ClientMapper extends MyBaseMapper<ContractDO> {

    /**
    * <p>
    * 聊天-新增
    * </p>
    */
    int insertSendOut( Long UserId, String imputOn, String data );

    /**
     * <p>
     * 聊天-查询
     * </p>
     */
    List<ClientVO> getSendOut();

}

XML

    <insert id="insertSendOut" >
        INSERT INTO keyan_user_chat (user_id, content, content_time) VALUES (#{UserId}, #{imputOn}, #{data});
    </insert>

    <select id="getSendOut" resultType="com.keyan.modules.client.vo.ClientVO">
        select t.id, user_id, content, content_time, y.nick_name, y.avatar_name from keyan_user_chat t LEFT JOIN sys_user y on t.user_id = y.id Order By content_time asc
    </select>

/**
* <p>
* 聊天
* </p>
*
* @author guoliang
* @since 2022-04-03
*/
@Data
@TableName(value = "user_chat", autoResultMap = true)
public class ClientVO implements Serializable {
   @ApiModelProperty(value = "ID")
   private Long id;

   @ApiModelProperty(value = "说话人")
   private Long userId;

   @ApiModelProperty(value = "内容")
   private String content;

   @ApiModelProperty(value = "时间")
   private String contentTime;

   @ApiModelProperty(value = "当前人Id")
   private String beforeOneId;

   @ApiModelProperty(value = "说话人名称")
   private String nickName;

   @ApiModelProperty(value = "头像地址")
   private String avatarName;

}

数据库

数据库里面有个列表页就是左侧列表，但是我还没有写完最近事情有点多，后续我会都放出来一起学习学习，
