我添加了接收的dto，整个页面就开始报错。

Question

@ApiModel
@Getter
@Setter
public class CashPaySelectDtoQuery extends CashPaySelectDto {

    @ApiModelProperty(value = "单据状态查询条件", example = "1", required = true)
    private String billStatus;
    @ApiModelProperty(value = "险种查询条件", example = "in ('310','320','330','340','350','360','390')", required = true)
    private String insuranceCodes;
    @ApiModelProperty(value = "单位查询条件", example = "[00, 01]", required = true)
    private List<String> agencyCodeList;
}

public class CashPaySelectDto {
    @NotBlank(message = "页码不能为空")
    @ApiModelProperty(value="页码",example="1",required=true)
    private Integer pageNum;
    @NotBlank(message = "分页大小不能为空")
    @ApiModelProperty(value="分页大小",example="1",required=true)
    private Integer pageSize;
    @ApiModelProperty(value="业务类型",example="01",required=true)
    @NotBlank(message = "业务类型不能为空")
    private String  businessType;
    @ApiModelProperty(value="页签标识（1 2 3 依次类推）",example="1",required=true)
    private String pageSign;
    @ApiModelProperty(value="单据号",example="1",required=true)
    private String fundNo;
    @ApiModelProperty(value="开始日期",example="20200519",required=true)
    private String startDate;
    @ApiModelProperty(value="结束日期",example="20200520",required=true)
    private String endDate;
    @ApiModelProperty(value="模糊查询条件",example="海淀",required=true)
    private String constr;

}

@PostMapping("/queryBillList")
@ApiOperation(value = "零星报销-提现|解款-提现|借款单列表", notes = "零星报销-提现|解款-提现|借款单列表")
public ResultMsg queryBill(@RequestBody CashPaySelectDtoQuery selectDto) {

是这个dto写的有问题吗

 

Answer 1

针对List类型的属性

@ApiModelProperty(value = "单位查询条件", example = "[00, 01]", required = true)
private List<String> agencyCodeList;

应该去除example

@ApiModelProperty(value = "单位查询条件", required = true)
private List<String> agencyCodeList;

这个会导致前端根据接口/v2/api-docs获得的json，转换成对象时抛出异常

Knfie4j会拿到接口后调用JSON.parse()方法，如果JSON非法，就会导致页面异常

Answer 2

报错代码要贴一下。
