杰克逊错误：没有这样的方法com.fasterxml.jackson.core.JsonGenerator.setCurrentValue（Ljava / lang / Object;）V

标签： java json spring maven spring-mvc

我正在开发一个Spring-MVC应用程序，从早上开始，当我调用特定的控制器方法时，我得到了与Jackson相关的错误。由于没有专门针对错误的行，我抬起头来发现这是一个POM问题。自星期五以来，我只添加了Google和Dropbox依赖项，这个问题似乎正在发生。我已经尝试排除Jackson-mapper，没有运气。

错误日志：

我应该在POM.xml中做出哪些更改，请告诉我。非常感谢。 ： - ）

我不知道您的图书馆需要哪个版本的jackson。

如果他们都需要1.9.x，那么删除对Jackson2的依赖，只留下对Jackson 2的依赖。

如果他们都依赖杰克逊2，那么就消除对杰克逊1.9的依赖，并依赖于杰克逊2。

如果某些人依赖杰克逊1而其他人依赖杰克逊1，那么你必须删除其中一个依赖关系，因为他们彼此不相容。

Spring可以使用1.x或2.x，但不能同时使用。

问题似乎与pom.xml中使用的jackson版本有关。

请参阅Jackson Json and no such method errors
