『博客开发日记-后台』之获取通知详情信息接口的实现

获取通知详情信息接口的实现

---

获取通知详情信息接口的需求

根据通知id 查询通知详情

回填发布人名称

---

代码实现

在 NoticeController 中添加接口

@GetMapping("/{id}/detail")
@SystemLog(businessName = "获取通知详情信息（用户查看通知信息时用上）")
@ApiOperation(value = "获取通知详情信息", notes = "获取通知详情信息，用户查看通知时用", response = NoticeFormDetailVo.class)
@ApiImplicitParams({
        @ApiImplicitParam(name = "id", value = "友链id", dataType = "long", paramType = "path")
})
public ResponseResult<NoticeDetailVo> getNoticeDetail(@PathVariable Long id)
{
    return sysNoticeService.getNoticeDetail(id);
}

---

创建 NoticeDetailVo

@Data
@AllArgsConstructor
@NoArgsConstructor
@Accessors(chain = true)
@ApiModel(description = "通知详情信息响应对象")
public class NoticeDetailVo
{
    @ApiModelProperty(value = "通知id", example = "6")
    private Long id;

    @ApiModelProperty(value = "通知标题", example = "这里是标题")
    private String title;

    @ApiModelProperty(value = "通知内容", example = "这里是内容")
    private String content;

    @ApiModelProperty(value = "通知类型（关联字典编码：notice_type）", example = "系统维护")
    private Integer type;

    @ApiModelProperty(value = "通知等级（字典code：notice_level）", example = "M")
    private String level;

    @ApiModelProperty(value = "状态（0: 未发布, 1: 已发布, 2: 已撤回）", example = "1")
    private String status;

    @ApiModelProperty(value = "目标人ID集合（多个使用英文逗号,分割）", example = "['1', '23']")
    private List<Long> targetUserIds;

    @TableField(exist = false)
    @ApiModelProperty(value = "发布人名称", example = "云梦泽")
    private String publisherName;

    @TableField(fill = FieldFill.INSERT_UPDATE)
    @ApiModelProperty(value = "发布时间", example = "2024-01-01 12:00:00")
    private Date publishTime;
}

在 NoticeServiceImpl 中

//获取通知信息详情
@Override
public ResponseResult<NoticeDetailVo> getNoticeDetail(Long id)
{
    //根据通知id 查询通知详情
    SysNotice notice = sysNoticeService.getById(id);
    if (notice == null) {
        return ResponseResult.errorResult(AppHttpCodeEnum.SYSTEM_ERROR, "该通知不存在！");
    }

    //转换成Vo
    NoticeDetailVo noticeDetailVo = BeanCopyUtils.copyBean(notice, NoticeDetailVo.class);

    //回填发布人名称
    if (notice.getPublisherId() != null) {
        SysUser publisher = sysUserService.getById(notice.getPublisherId());
        if (publisher != null) {
            noticeDetailVo.setPublisherName(StringUtils.hasText(publisher.getNickname()) ? publisher.getNickname() : publisher.getUsername());
        }
    }

    //返回
    return ResponseResult.okResult(noticeDetailVo);
}
