我们有一个相当复杂的Spring Boot项目，在开发过程中它在Windows上运行良好。但是，当我们在Ubuntu上运行该项目时，会遇到一个奇怪的例外情况

在Ubuntu上，我们使用的是OpenJDK11。它可以在具有相同JDK的Windows上运行，但不能在Ubuntu上使用。我们还尝试在新的Windows Sandbox实例中运行该项目，并且该项目运行正常。

2 个答案:

答案 0 :(得分：0)

不确定，但是我认为由spring-core依赖性引起的问题。您能否尝试从pom.xml文件中删除spring-core依赖项并尝试再次运行它。

答案 1 :(得分：0)

此问题是由于尝试创建具有 0 个线程的线程池引起的。我们有一个带有 1 线程的开发VPS，我们有如下代码：

public static final Executor EXECUTOR = Executors.newFixedThreadPool(Runtime.getRuntime().availableProcessors() - 1);

这导致了异常。事后看来，异常堆栈跟踪在底部提供了明显的线索

at redacted.Config.<clinit>(Config.java:43)

从字面上指向出现故障的确切行。

您绝对应该做的另一件事是使用sudo apt-get update命令更新apt-cache，以安装最新的OpenJDK版本。
