For Spring Boot 1.2.3, how to set ignore null value in JSON serialization?
提问by crisli
In the Spring Boot 1.2.3, we can customize the Hymanson ObjectMapper via properties file. But I didn't find a attribute can set Hymanson ignore null value when serialization the Object to JSON string.
在 Spring Boot 1.2.3 中，我们可以通过属性文件自定义 Hymanson ObjectMapper。但是我没有发现在将 Object 序列化为 JSON 字符串时可以设置 Hymanson 忽略空值的属性。
spring.Hymanson.deserialization.*= # see Hymanson's DeserializationFeature
spring.Hymanson.generator.*= # see Hymanson's JsonGenerator.Feature
spring.Hymanson.mapper.*= # see Hymanson's MapperFeature
spring.Hymanson.parser.*= # see Hymanson's JsonParser.Feature
spring.Hymanson.serialization.*=
I want to archive the same code like
我想归档相同的代码
ObjectMapper mapper = new ObjectMapper();
mapper.setSerializationInclusion(Include.NON_NULL);

This was an enhancement for Spring Boot 1.3.0.
这是 Spring Boot 1.3.0 的增强。
So unfortunately you'll need to configure it programmatically on 1.2.3
所以不幸的是你需要在 1.2.3 上以编程方式配置它
@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)
public class Shop {
//...
}

Add the following line to your application.propertiesfile.
将以下行添加到您的application.properties文件中。
spring.Hymanson.default-property-inclusion=non_null
spring.Hymanson.default-property-inclusion=non_null
For versions of Hymanson prior to 2.7:
对于 2.7 之前的 Hymanson 版本：
spring.Hymanson.serialization-inclusion=non_null
spring.Hymanson.serialization-inclusion=non_null

This was a good solution before deprecation:
@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)
这是弃用之前的一个很好的解决方案：
@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)
But now you should use:
但现在你应该使用：
@JsonInclude(JsonInclude.Include.NON_NULL)
public class ClassName {
...
@JsonInclude(JsonInclude.Include.NON_NULL)
public class ClassName {
...
You can take a look here: https://fasterxml.github.io/Hymanson-annotations/javadoc/2.7/com/fasterxml/Hymanson/annotation/JsonInclude.Include.html
您可以在这里查看：https: //fasterxml.github.io/Hymanson-annotations/javadoc/2.7/com/fasterxml/Hymanson/annotation/JsonInclude.Include.html

Class-wide,
全班，
@JsonInclude(JsonInclude.Include.NON_NULL)
public class MyModel { .... }
Property-wide:
物业范围：
public class MyModel {
.....
