在Spring应用中，出现了一个BeanPropertyBindingResult的2个错误，涉及到userParam对象的endTime和startTime字段。错误指出无法将字符串'2021-03-30T16:00:00.000Z'和'2021-03-29T16:00:00.000Z'转换为Date类型，导致ConversionFailedException。问题源于Swagger请求参数格式与Controller中参数类型不匹配。

接收参数的DTO

@Data
public class UserParam {
    @ApiModelProperty("手机号")
	private String mobile;
    @ApiModelProperty("开始时间")
	private Date startTime;
	@ApiModelProperty("结束时间")
	private Date endTime;
}

Controller


```java

```java

```java

```java
@RestController
@RequestMapping("/v1/client")
@Api(value = "C端用户管理", tags = "C端用户管理相关接口")
public class ClientController {
    @Autowired
	IClientService iClientService;
	@GetMapping("/clientQueryList")
	public PageResult clientQueryList(UserParam userParam,
									@ApiParam @RequestParam(value = "pageIndex",required = false,defaultValue = "1") Long pageIndex,
									@ApiParam  @RequestParam(value = "pageNum",required = false,defaultValue = "10") Long pageNum) {

		return iClientService.queryClientList(userParam, pageIndex, pageNum);



	}
}
