在我的Spring Boot 1.4.0.BUILD-SNAPSHOT应用程序中，当我在Ubuntu服务器上运行测试时，我遇到了以下问题（本地一切正常）：
ERROR o.s.test.context.TestContextManager - Caught exception while allowing TestExecutionListener [org.springframework.boot.test.autoconfigure.AutoConfigureReportTestExecutionListener@3b0090a4] to prepare test instance [com.example.api.controller.v1.index.IndexControllerTest@3af9c5b7]

最后，我已经使用此问题Spring Boot Actuator application won't start on Ubuntu VPS中所述的其他VM参数-Djava.security.egd=file:/dev/./urandom启动了我的应用程序，但我在此Ubuntu服务器上的测试仍然没有运气
