获取字典项表单数据接口的实现
获取字典项表单数据接口的需求
根据字典项id 查询字典项
代码实现
在 DeptController 中添加接口
1 2 3 4 5 6 7 8 9 10 11 12
| @GetMapping("/{dictCode}/items/{id}/form") @PreAuthorize("@ps.hasPermission('blog:dict:update')") @SystemLog(businessName = "获取字典项表单数据接口") @ApiOperation(value = "获取字典项表单数据接口", notes = "获取字典项表单数据,用于编辑字典项详情", response = DictItemFormDetailVo.class) @ApiImplicitParams({ @ApiImplicitParam(name = "id", value = "字典id", dataType = "long", paramType = "path"), @ApiImplicitParam(name = "dictCode", value = "字典编码", dataType = "string", paramType = "path") }) public ResponseResult<DictItemFormDetailVo> getDictItemFormDetail(@PathVariable Long id, @PathVariable String dictCode) { return sysDictItemService.getDictItemFormDetail(id, dictCode); }
|
创建 DictItemFormDetailVo
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28
| @Data @AllArgsConstructor @NoArgsConstructor @ApiModel(description = "字典项表单详情响应对象") public class DictItemFormDetailVo { @ApiModelProperty(value = "字典项ID", example = "1") private Long id;
@ApiModelProperty(value = "字典编码", example = "sex") private String dictCode;
@ApiModelProperty(value = "字典项标签", example = "男") private String label;
@ApiModelProperty(value = "字典项值", example = "0") private String value;
@ApiModelProperty(value = "状态(0-正常,1-禁用)", example = "0") private String status;
@ApiModelProperty(value = "排序", example = "1") private Integer sort;
@ApiModelProperty(value = "标签类型,用于前端样式展示(如success、warning等)", example = "success") private String tagType; }
|
在 SysDictItemServiceImpl 中
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
| @Override public ResponseResult<DictItemFormDetailVo> getDictItemFormDetail(Long id, String dictCode) { SysDictItem dictItem = sysDictItemService.getById(id); if (dictItem == null) { return ResponseResult.errorResult(AppHttpCodeEnum.SYSTEM_ERROR, "该字典项不存在!"); }
DictItemFormDetailVo dictItemFormDetailVo = BeanCopyUtils.copyBean(dictItem, DictItemFormDetailVo.class);
return ResponseResult.okResult(dictItemFormDetailVo); }
|
需要注意的是
为了避免重复代码过多
我将 获取当前用户拥有的数据权限范围 相关的代码提取出来成 applyDeptDataScopeFilter 方法方便调用了
并且在 AdminUserServiceImpl 中也进行了类似的操作

不一定符合读者来学习,仅供参考
预告
后续会记录博客的开发过程
每次学习会做一份笔记来进行发表
