如果字段的值为空,那么如何将Jackson配置为在序列化期间忽略该字段值。
例如:
public class SomeClass {
// what jackson annotation causes jackson to skip over this value if it is null but will
// serialize it otherwise
private String someValue;
}

就我而言
@JsonInclude(Include.NON_EMPTY)
让它发挥作用。
其他回答
这将适用于Spring boot 2.0.3+和Jackson 2.0+
import com.fasterxml.jackson.annotation.JsonInclude;
@JsonInclude(JsonInclude.Include.NON_NULL)
public class ApiDTO
{
// your class variable and
// methods
}
就我而言
@JsonInclude(Include.NON_EMPTY)
让它发挥作用。
对于Jackson 2.5使用:
@JsonInclude(content=Include.NON_NULL)
您可以设置application.properties:
spring.jackson.default-property-inclusion=non_null
或application.yaml:
spring:
jackson:
default-property-inclusion: non_null
http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html
在Jackson 2.x中,使用:
@JsonInclude(JsonInclude.Include.NON_NULL)
