对于Spring Boot1.2.3，如何在JSON序列化中设置忽略空值？

Question

spring.jackson.deserialization.*= # see Jackson's DeserializationFeature
spring.jackson.generator.*= # see Jackson's JsonGenerator.Feature
spring.jackson.mapper.*= # see Jackson's MapperFeature
spring.jackson.parser.*= # see Jackson's JsonParser.Feature
spring.jackson.serialization.*=

ObjectMapper mapper = new ObjectMapper();
mapper.setSerializationInclusion(Include.NON_NULL);

Answer 1

这是Spring Boot 1.3.0的增强。

• 支持Spring.Jackson.Include
• 添加Jackson SerializationInclusive的属性

因此不幸的是，您需要在1.2.3上以编程方式配置它

@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)
public class Shop {
    //...
}
