Which one to use for skipping field for serialization and de-serialization.
@JsonIgnore why we should use it if @Transient also skips the field from serialization and de-serialization process?

@JsonIgnore is used to ignore the logical property used in serialization and deserialization. @JsonIgnore can be used at setters, getters or fields. If you add @JsonIgnore to a field or its getter method, the field is not going to be serialized.
The. @JsonIgnore. annotation marks a field in a POJO to be ignored by Jackson during serialization and deserialization. Jackson ignores the field in both JSON serialization and deserialization.
To ignore individual properties, use the [JsonIgnore] attribute. You can specify conditional exclusion by setting the [JsonIgnore] attribute's Condition property.
The @JsonPropertyOrder is an annotation to be used at the class-level. It takes as property a list of fields that defines the order in which fields can appear in the string resulting from the object JSON serialization.
The clear difference between the two is that @Transient is used as part of JPA to ignore a field from persisting if it is marked as @Transient.
Where as @JsonIgnore is only used to Ignore a marked field from being serialized, de-serialized to and from JSON.
Which means a field marked as @JsonIgnore can still be persisted in a JPA persistence where as a field marked @Transient will neither be persisted nor be serialized, de-serialized.
