java - Play 框架中的内部服务器错误

Question

我想在 Play 框架中渲染一个简单的页面该页面位于 localhost:9000/upload

但是当我尝试加载此页面时，我得到了这个奇怪的堆栈跟踪。错误不是编译也不是运行时。这是一些堆栈跟踪行。 ---(从 SBT 运行应用程序，启用自动重新加载)---

  [info] play - Listening for HTTP on /0.0.0.0:9000

  (Server started, use Ctrl+D to stop and go back to the console...)

  [info] play - database [default] connected at jdbc:mysql://192.168.2.250:3306/DP

我尝试在我的项目目录中设置 _JAVA_OPTION = -XX:-UseSplitVerifier 然后尝试运行。 cmd 行应该显示 "Picked up _JAVA_OPTIONS: -XX:-UseSplitVerifier" 但我也没有得到。 (我很困惑是 JAVA_OPTION 还是 _JAVA_OPTION)。我什至在环境变量中设置了相同的 JAVA_OPTION

Answer 1

错误是由 javaassist 上的错误引起的。新版本 3.18.2 已解决。添加到project/plugins.sbt如下

libraryDependencies += "org.javassist" % "javassist" % "3.18.2-GA"
