XStream中的单元素数组错误 [英] Single element array bug in XStream

问题描述

如果您具有这样的功能:

If you have a function like this:

List<User> getUsers() {}

如果getUsers返回仅包含一个元素的List，则生成的JSON只是JSON对象，而不是JSON数组.

If getUsers returns a List with just one element the resulting JSON is just a JSON Object rather than a JSON array.

是否存在使XStream返回JSON数组的变通办法，而不管该函数是否返回单个数组List?

Is there a workaround to make XStream return JSON array regardless if the function returns single array List?

推荐答案

解决方案是降级到Jettison 1.2
