IntelliJ调试断点不适用于Tomcat运行配置

郏实
2023-03-14

我有一个带有endpoint的小型应用程序，它调用了一些转换器库。我的运行配置类型为Tomcat并部署了一个爆炸战争，这是我的应用程序。

在＜code＞pom中。xml的

当我在调试模式下启动 Tomcat 运行配置时，日志指示代理似乎已正确设置并且工件已成功部署（以下是我认为相关的日志子集）：

然后，我可以看到我的断点由于白色复选标记而被注册：

但是，这仅适用于模块的src/main/java目录中的代码。我正在尝试调试的库（在外部库中找到）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，并在库和我的应用程序中运行mvn干净安装，以确保我指向了正确的代码版本。

现在，奇怪的部分来了。当我运行调用应用程序endpoint的测试时，我会看到以下日志：

com.my.app.ExecutionServiceException: java.lang.NullPointerException: TheConverter.java, notWithinYearBoundaries line 1110
    at com.my.app.handleTransaction(MyAppEndpointHandler.java:143)

这向我证明了我在日志记录（L1109）上有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，当我单击< code > myappendpointhandler . Java:143 时，IntelliJ确实打开了我在其中设置了标记为已注册的断点的类(是的，< code>L61与< code>L143在同一个函数内)。

  1. 当代码到达L61上的注册断点时，IntelliJ甚至不会中断正在运行的应用程序向我显示调试窗口
  2. IntelliJ拒绝在外部库中注册断点

这很令人不安，我尝试了很多不同的事情（我在另一个SO问题中看到的一堆东西，除其他外）：

  1. 干净

值得一提的是，我团队中的另外两名开发人员报告说，在他们的机器上，他们没有遇到我的问题。我们似乎必须使用相同的IntelliJ配置和设置。

以下是 Tomcat 运行配置：

以下是我的< code >调试器设置:

以下是控制台日志的部分版本：

原来是误会。我以为 Test 类正在对本地主机 Tomcat 实例进行网络调用，而实际上它直接调用了源代码。

这就是为什么当我在调试模式下启动 Tomcat 运行配置时，我会在我的源代码中获得一个注册的断点，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，所以我认为日志来自Tomcat。

从Debug模式下启动的Test类开始，我进入了应用程序代码，最终也进入了库代码。这也是为什么我在调试模式下启动Tomcat运行配置后，在正常运行测试类时，看到了来自库的日志，但没有看到注册的断点。

啊。那是一次尴尬而耗时的旅程。
