从带有循环依赖项的Jersey获得JSON [英] Getting JSON from Jersey with circular dependencies

问题描述

我正在编写一个使用Jersey和JAXB的服务.我的类使用@ XMLRootElement，@ XMLElement等进行注释.我在两个类之间具有循环依赖关系，因此我已使用@XMLTransient注释了循环依赖属性.因此，当我调用我的服务时，我将xml作为默认值，这可以正常工作.但是，当我尝试使用JSON时，会出现类似以下的重复行:

I am writing a service that uses Jersey and JAXB. My classes are annotated with @XMLRootElement, @XMLElement, etc. I have a circular dependency between two classes, so I have annotated the circular dependent property with @XMLTransient. So when I call my service I get xml as the default, which works perfectly. However, when I try using JSON, I get repeated lines like:

{"name":"dere"，"entries":[{"points":0，"wins":0，"losss":0，"tie":0，排行榜":{"name" :"dere"，"entries":[{积分":0，获胜":0，亏损":0，平局":0，排行榜":{名称":"dere"，"entries :[{" points:0，" wins:0，" losss:0，" tie:0，"排行榜:{" name:" dere，" entries:[{" points":0，获胜":0，亏损":0，平局":0，排行榜":{名称":"dere"，"...等.

{"name":"dere","entries":[{"points":0,"wins":0,"losses":0,"ties":0,"leaderboard":{"name":"dere","entries":[{"points":0,"wins":0,"losses":0,"ties":0,"leaderboard":{"name":"dere","entries":[{"points":0,"wins":0,"losses":0,"ties":0,"leaderboard":{"name":"dere","entries":[{"points":0,"wins":0,"losses":0,"ties":0,"leaderboard":{"name":"dere"," ... etc.

因此，当我使用JSON时，似乎循环依赖存在问题.我想避免循环依赖项出现在JSON输出中，就像在XML中那样(由于@XMLTransient批注).

So it seems there is a problem with circular dependencies when I am using JSON. I would like to avoid the circular dependent item from showing up in the JSON output, like it is done in XML (because of the @XMLTransient annotation).

任何人都可以提供关于我将如何实现这一目标的任何见解吗?

Can anyone provide any insight on how I would be able to achieve this?

推荐答案

使用

Use @JsonIgnore instead of @XmlTransient to break the circular dependency.

我遇到了与您类似的问题，这为我解决了问题.

I had a similar problem as you and this did the trick for me.
