为什么我得到这个？我该怎么做才能解决这个问题？

2 个答案:

答案 0 :(得分：3)

我可以使用停用默认TomcatURLStreamHandlerFactory来修复此问题 在启动服务器实例之前

TomcatURLStreamHandlerFactory.disable();

答案 1 :(得分：1)

使用故障安全插件运行集成测试时，我遇到了类似的异常。通过设置redirectForks = false修复了该问题-这使Maven无法重用分叉的VM。

  <configuration>
    <reuseForks>false</reuseForks>       <!-- FIXES THE EXCEPTION
