杰克逊映射器写入id而不是整个对象 [英] Jackson mapper write id instead of entire object

问题描述

我使用jackson 2.4.2来编写一些hibernate结果，因为hibernate对象可能相当复杂，我收到的问题是，我有一个hibernate对象列表，其中一些可能引用同一个对象，因此，jackson只对对象进行一次mapp，而所有其他对象只被映射为id。我不希望它表现得像这样，并且希望它将对象写为对象，无论它是否在其他对象中进行解析。

I am using jackson 2.4.2 to mapp some hibernate results, because the hibernate object can be quite complex, the problem I am receiving is, I have a list of hibernate object, some of them may refer to the same object, thus jackson only mapp the object once, and all other objects are only mapped as an id. I don't want it behave like this and want it to write objects as object no matter if it is parse in other object or not.

推荐答案

向我们展示一些代码，特别是你的类结构和json / xml或其他结果。

Show us some code and especially your class structure and json/xml or whatever results.

但我认为问题是你只是将object_id保存为Integer而不是作为对象。

But i think the problem is that you are only saving object_id as Integer and not as object.

错误：

public class Foo {
    private String name;
    private Integer foo_id;
}

正确：

public class Foo {
    private String name;
    private Foo foo;
}
