Notes on Json parsing tool Jackson

@ JsonIgnoreProperties

This annotation is a class annotation that ignores some attributes in Java bean when json serialization, and both serialization and deserialization are affected.

@ JsonIgnore

This annotation is used on properties or methods (preferably on properties) and works the same as @ JsonIgnoreProperties above.

@ JsonFormat

This annotation is used on properties or methods (preferably on properties), and it is convenient to convert Date types directly into the schema we want, such as @ JsonFormat (pattern = "yyyy-MM-dd HH-mm-ss").

@ JsonProperty

This annotation is used on an attribute to serialize the name of the attribute to another name, such as serializing the trueName attribute to name,@JsonProperty ("name").

@ JsonSerialize

This annotation is used on properties or getter methods to embed our custom code when serializing, such as limiting two decimal places after a double serialization.

@ JsonDeserialize

This annotation is used on properties or setter methods to embed our custom code when deserializing, similar to @ JsonSerialize above

@ JsonInclude (Include.NON_NULL) / / put the tag on the attribute, if the attribute is NULL, do not participate in serialization / / if placed on top of the class, it has an effect on all properties of the class

Other options

/ / Include.ALWAYS default / / Include.NON_DEFAULT attribute is the default value does not serialize / / Include.NON_EMPTY attribute is empty ("") or NULL does not serialize / / Include.NON_NULL attribute is NULL does not serialize does it help you to read the above?
