我有一个小型应用程序，其端点调用一些转换器库。我的Run Configuration类型为Tomcat并部署了一场爆炸 war ，这是我的应用程序。
在 pom.xml的<dependencies>对于该应用程序，我有一个需要调试的外部库。显然，该库是在我的应用程序中调用的。
当我启动Tomcat Run Configuration时在Debug模式下，日志表明代理似乎已正确设置并且 Artifact 已成功部署(以下是我认为相关的日志子集):

然后，我可以看到由于白色复选标记，我的断点已注册:
但是，这只适用于模块的 src/main/java 中的代码。目录。我正在尝试调试的库，可以在 External Libraries 中找到。 ，不会注册其断点:
我添加了几行日志记录，并修改了该库的 pom.xml 中的版本并跑了mvn clean install在库和我的应用程序中，以确保我指向代码的正确版本。
诊断
现在奇怪的部分来了。当我运行调用应用程序端点的测试时，我看到以下日志:
com.my.app.ExecutionServiceException: java.lang.NullPointerException: TheConverter.java, notWithinYearBoundaries line 1110
at com.my.app.handleTransaction(MyAppEndpointHandler.java:143)
这向我证明，我在日志记录 ( L1109 ) 上设置断点的库代码确实正在运行(并且我在 Tomcat 日志中看到了实际日志)。
此外，当我点击MyAppEndpointHandler.java:143时，IntelliJ 确实打开了我设置断点的类，该断点被标记为已注册(是的， L61 与 L143 位于同一函数内)。
问题
- 当代码到达
L61上注册的断点时，IntelliJ 甚至不会中断正在运行的应用程序来向我显示调试窗口。 . - IntelliJ 拒绝在外部库中注册我的断点。
我尝试过的事情
这非常令人不安，我尝试了很多不同的事情(我在 that other SO question 中看到的一堆东西，等等):
-
clean & rebuild - 关闭所有项目，并删除
target,.idea/，和*.iml - 更新我的 IntelliJ 版本(从
2020.3到2020.3.2) - 尝试其他版本的 Tomcat
-
Invalidate Caches & Restart - 还有更多...
值得一提的是，我团队中的另外两名开发人员报告说，在他们的计算机上，他们没有遇到我的问题。而且我们似乎具有相同的 IntelliJ 配置和设置。
设置和运行配置
这是 Tomcat Run Configuration :
这是我的Debugger设置:
IntelliJ 调试控制台输出
这是控制台日志的部分版本:

断点属性
最佳答案
原来是有误会。我以为 Test 类正在对 localhost Tomcat 实例进行网络调用，而实际上它直接调用源代码。
这就是为什么当我在 Debug模式下启动 Tomcat 运行配置时，我会在源代码中获得一个已注册的断点，但它永远不会挂起应用程序，尽管我看到了日志。
由于应用程序被配置为在 target 中的文件中输出日志，因此我认为日志来自 Tomcat。
从以 Debug模式启动的测试类中单步执行，将我带到应用程序代码，并最终到达库代码。这也是为什么我在 Debug模式下启动 Tomcat 运行配置后正常运行测试类时看到来自库的日志，但没有看到注册的断点。
呃。这是一次尴尬且耗时的旅程。
关于java - IntelliJ 调试断点不适用于 Tomcat 运行配置，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/66125604/
