我遇到了一个问题，我无法将一些json转换为java对象。这个问题在这里：Spring + Jackson + Deserializing List of Generic Objects。现在，我能够通过从3.0.3弹簧升级到3.2弹簧来解决这个问题。
我现在面临的问题如下。我的序列化/反序列化在我的webapp上运行正常，但它不在我的单元测试中。当我运行/调试它们时，我发现我遇到了同样的问题（另一个在stackoverflow帖子上）。我认为我的依赖关系肯定存在冲突，但在花了一整天的时间调查之后，我才空了。
我的项目是一个多模块maven项目，我有一个依赖项的pom，一个主项目的pom，以及每个模块的pom。
依赖关系POM：

有关我部署的代码为何有效而不是我的单元测试的任何想法？
答案 0 :(得分：0)
你是如何部署它的？容器的lib文件夹可能包含测试范围内不可用的额外jar，因此类路径差异。
