java - 是什么导致了 java.lang.NoSuchMethodError : com. fastxml.jackson.core.JsonFactory.requiresPropertyOrdering()Z

Question

查看有关此错误的类似帖子，问题似乎来自于同一依赖项的不兼容版本。我有一个项目从另一个项目调用一个类，因此我有两个单独的 pom.xml，但两者都具有相同版本的 jackson 依赖项，所以我不确定是什么导致了此错误。这是我的两个 pom.xml:

pom.xml #1

当单独运行每个类时，它们都按预期编译和运行，但是当我从类 a 调用 b.foo() 时，我在标题中收到错误。知道发生了什么吗？

Answer 1

我更深入地研究了一些依赖项，发现其中一个使用的是 jackson 的较低版本，你在表面上看不到。因此，如果您遇到此问题并且正在使用 Eclipse，请通过“依赖关系层次结构” View 查看您的 pom.XML，您应该能够看到不兼容的根源。
