SpringDocs-OpenAPI3-如何设置body的默认值？

我使用Spring Boot+Spring Data Mongo+Spring REST+Spring HATEOAS实现REST端点

由于我们要传递5个以上的查询参数（一个组织的专有设置，应该不会被传递），所以我想创建一个EmployeeDto类并在Controller上传递该类

@GetMapping(value = "/employees", produces = {MediaType.APPLICATION_JSON })
public ResponseEntity<PagedModel<EmployeeModel>> findEmployees(
        EmployeeDto dto,
        @Parameter(hidden=true) String sort,
        @Parameter(hidden=true) String order,
        @Parameter(hidden=true) Pageable pageRequest) {

    // Add needed logic 
    ......
    ......
    ......
    PagedModel<EmployeeModel> model = employeePagedAssembler.toModel(response, employeeAssembler);

    return new ResponseEntity<>(model, HttpStatus.OK);
}

CURL命令：

curl-X GET“--H”accept:application/json

EmployeeDto.java

@AllArgsConstructor
@NoArgsConstructor
@Data
@Builder
@Schema
public class EmployeeDto {
    @Schema(description = AppConstants.FIRSTNAME, defaultValue="")
    private String firstName; 

    @Schema(description = AppConstants.LASTNAME, defaultValue="")
    private String lastName; 

    @Schema(description = AppConstants.AGE, defaultValue="")
    private Integer age; 

    @Schema(description = AppConstants.LANG_CD_DESC, defaultValue="0")
    private String languageCd;

    @Schema(description = AppConstants.ISACTIVE, defaultValue="")
    private String isActive; 

    @Schema(description = AppConstants.EMAIL, defaultValue="")
    private String email; 

    @Schema(description = AppConstants.REGION_CD_DESC, defaultValue="")
    private String regionCd;
}

我正在寻找-

1） 如何为每个字段设置默认值，而不是似乎是默认值的“字符串”

---

2） 如何简单地允许在OAS3UI中查看实际的查询参数？货币，它看起来像身体。

我自己能够解决这个问题<代码>示例-提供架构的示例。当与特定媒体类型关联时，消费者应将示例字符串解析为对象或数组。

代码-

@AllArgsConstructor
@NoArgsConstructor
@Data
@Builder
@Schema
public class EmployeeDto {
    @Schema(description = AppConstants.FIRSTNAME, type = "string", example = " ")
    private String firstName; 

    @Schema(description = AppConstants.LASTNAME, type = "string", example = " ")
    private String lastName; 

    @Schema(description = AppConstants.AGE, type = "string", example = "null")
    private Integer age; 

    @Schema(description = AppConstants.LANG_CD_DESC, type = "string", example = " ")
    private String languageCd;

    @Schema(description = AppConstants.ISACTIVE, type = "string", example = " ")
    private String isActive; 

    @Schema(description = AppConstants.EMAIL, type = "string", example = " ")
    private String email; 

    @Schema(description = AppConstants.REGION_CD_DESC, type = "string", example = " ")
    private String regionCd;
}

在控制器上，只需添加下面的方法，如果发送的值

“null”

将重置，如果是，则将重置为

”

，对于

整数

将重置为

null

public static Object getDefaulter(Object obj) {
    Arrays.stream(obj.getClass().getDeclaredFields()).map(f -> {
        f.setAccessible(true);
        try {
            // set null values only if found String value as "null"
            if (Objects.equals(f.get(obj), "null")) {
                f.set(obj, "");
            }else if(Objects.equals(f.get(obj), 0)) {
                f.set(obj, null);
            }
        } catch (IllegalArgumentException | IllegalAccessException e) {
            //
        }
        return f;
    }).collect(Collectors.toList());
    return obj;
}

不起作用。带空格的字符串将被忽略，就像空字符串一样。

public static Object getDefaulter(Object obj) {
    Arrays.stream(obj.getClass().getDeclaredFields()).map(f -> {
        f.setAccessible(true);
        try {
            // set null values only if found String value as "null"
            if (Objects.equals(f.get(obj), "null")) {
                f.set(obj, "");
            }else if(Objects.equals(f.get(obj), 0)) {
                f.set(obj, null);
            }
        } catch (IllegalArgumentException | IllegalAccessException e) {
            //
        }
        return f;
    }).collect(Collectors.toList());
    return obj;
}
