linux - 在 Linux 服务器上通过 xldeploy 和 jenkins 部署 thin jar 时出错

Question

我有一个 spring boot/batch 应用程序，它在使用 jenkins 和 xldeploy 部署时抛出错误。它是一个渐变应用程序。

当我将它作为一个 fat jar 直接部署在服务器上时它工作正常，但是当我通过 jenkins 和 xldeploy 部署该 jar 时它给我以下错误。

Answer 1

根本原因是类路径中有 spring-boot-devtools。删除 devtools 解决了问题。所以在这种情况下，问题基本上出在 AOP 代理上。出于某种原因，我们必须关闭 AOP 代理，这将确保它使用 JDK 代理，这可以通过删除 spring-boot-devtools jar 来完成，删除它会启动它以使用 native JDK 代理并修复此错误。
