我的一个spring启动应用程序不能在ide(sts4.9.0)中运行。maven构建运行没有任何问题。但是,如果我想使用引导面板在sts中运行应用程序,则会出现以下错误:

java.lang.NoSuchMethodError: org.springframework.core.type.AnnotationMetadata.introspect(Ljava/lang/Class;)Lorg/springframework/core/type/AnnotationMetadata;

正如消息告诉我的那样,加载的spring核心库有两个不同的版本,一个是maven依赖的正确版本,另一个是包含的osgi包中的错误版本。我真的很想纠正消息中建议的类路径,以排除osgi资源。但我不知道怎么做。在项目属性(java构建路径)和springboot应用程序的调试配置中都没有提到osgi库的使用。很明显,它们是隐含的。有人知道如何把它们排除在类路径之外吗?提前谢谢!

现在我知道了这听起来很简单的原因,但我确实花了一些时间才弄明白。正是一连串的依赖关系导致了这种奇怪的行为:
在我的sts中,我安装了jaspersoft工作室。
在kita formular引导项目的java构建路径中,我添加了另一个项目(kita资源)作为必需的项目。
kita资源包含一些jrxml文件。为了让他们编译,我已经把jasperreports nature添加到了这个项目中。
执行此操作时,jasperreports库依赖项会自动添加到java构建路径中。
这些依赖项包括导致问题的旧的spring核心版本。
通过根据项目需要设置kita资源,kita资源中的所有类路径也包含在kita公式引导中。所以我所要做的就是从kita参考资料中的java构建路径中删除jasperreports库依赖项。很明显,它们不是编译项目所必需的。所有的冲突都消失了!
