@JsonIgnoreProperties @JsonIgnoreProperties(value = { "prop1","prop2" })用来修饰Pojo类, 在序列化和反序列化的时候忽略指定的属性, 可以忽略一个或多个属性. @JsonIgnoreProperties(ignoreUnknown = true)用来修饰Pojo类, 在反序列化的时候忽略那些无法被设置的属性, 包括无法在构造子设置和没有对应的setter...
9. @JsonSerialize 和 @JsonDeserialize @JsonSerialize 和 @JsonDeserialize 注解用于指定自定义的序列化和反序列化器。这在处理复杂的数据类型或需要定制序列化逻辑的情况下非常有用。publicclassUser {@JsonSerialize(using = CustomDateSerializer.class)@JsonDeserialize(using = CustomDateDeserializer.class)private ...
情况一和情况二说明了public static String toJSONString(Object object, SerializeFilter filter, SerializerFeature… features)这个方法将实体对象转换成JSON字符串时,默认是忽略掉值为null的属性,并且说明了如何使得转换后的JSON字符串包含值为null的属性。

6.@JsonDeserialize此注解用于属性或者setter方法上,用于在反序列化时可以嵌入我们自定义的代码,类似于上面的@JsonSerialize。 7.@JsonInclude 属性值为null的不参与序列化。例子:@JsonInclude(Include.NON_NULL)
