Hi all, Just found the behaviour relate to JsonIgnore annotation. The cause is described here: http://stackoverflow.com/questions/27571380/jackson-prefers-private-constructor-over-jsoncreator-when-deserializing-a-class
So JsonIgnore can be used not only for property getter/setter. It can be used for a constructor of the Java class. Unfortunately it is not described neither http://tutorials.jenkov.com/java-json/jackson-annotations.html#jsonignore nor http://www.baeldung.com/jackson-annotations nor https://github.com/FasterXML/jackson-annotations/wiki/Jackson-Annotations. So I suggest to add this description at least here https://github.com/FasterXML/jackson-annotations/wiki/Jackson-Annotations Regards, Alex -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
