我正在使用intellij Idea来调试在tomcat上运行的应用程序。但我有一个问题，在某些类中，行断点不起作用（方法断点工作正常......但速度慢）。我可以通过从方法断点或从另一个类进入类来获取特定的代码行或检查变量，但调试器不会在任何行上停止。 （IntelliJ显示空的红色圆圈（没有交叉））
更新：此问题不仅限于Tomcat。我在Weblogic上遇到了与不同项目相同的问题。所以这可能是Idea或Java的问题。
可能的原因是什么？没有特殊的编译器选项，当我反编译类时，LineNumberTables和LocalVariableTables就在那里。这两个类（行断点很好，一个不行）在同一个包中。我的源完全匹配已部署的代码。我已经清除了所有intellij想法缓存（也是[system] / jars，这里建议：Debugger doesn't stop at source code in Intellij IDEA）
当我按照CrazyCoder的建议在Idea中启用调试器跟踪时，我得到了这些结果（显示我在想法中添加/删除行断点时的输出）：

我有完全相同的问题，并且刚刚解决了 - 不知道你的设置是否相同但我的问题是我的类文件被输出到我的模块的内容根目录下的文件夹中（即使我确实在模块设置中将文件夹标记为已排除。
我删除了所有本地类文件，将编译器输出设置更新为指向我的内容根目录，重建项目，现在一切正常。

我已经收到了对intelliJ Idea服务台的进一步支持，问题暂时存在？通过从我的本地maven存储库中删除war文件来修复。
