JSON 序列化的 Micronuat 默认配置JsonInclude.Include.NON_EMPTY
不包含空值或 null 值。但是,我需要包含空值和空值,所以我到目前为止所做的 -
@Introspected
@JsonInclude(ALWAYS)
public class FindVendorViewModel extends PaginationViewModel {
private List<VendorViewModel> vendors;
public List<VendorViewModel> getVendors() {
return vendors;
}
public void setVendors(List<VendorViewModel> vendors) {
this.vendors = vendors;
}
}
分页模型
@Introspected
@JsonInclude(ALWAYS)
public class PaginationViewModel {
int pageSize = 10;
int total = 0;
int currentPage = 0;
int totalPage = 0;
@Valid
@LastIdRequired
String lastId;
// Getter and setter
}
当我添加@JsonInclude(ALWAYS)时,它不会在 JSON 响应中包含NULL或EMPTY值,如下所示。
{
"pageSize": 10,
"total": 28,
"currentPage": 0,
"totalPage": 3
}
如果我添加下面的代码,它确实包含NULL或EMPTY值lastId
vendors
jackson:
serializationInclusion: ALWAYS
{
"pageSize": 10,
"total": 0,
"currentPage": 0,
"totalPage": 0,
"lastId": null,
"vendors": []
}
但是,它会引发如下异常
