Failed to load ApplicationContext when running Spring boot integration test
提问by Bhabani pattanayak
I am trying to write integration test for spring boot. I want the server should be up during test so that I can connect the client from the test code. Using java 1.7. I am getting exception when running as maven test. (From console)
我正在尝试为 Spring Boot 编写集成测试。我希望服务器在测试期间应该启动，以便我可以从测试代码连接客户端。 使用 java 1.7。作为 maven 测试运行时出现异常。（来自控制台）

I'm also using Java 7 and I encountered this error. To my knowledge, none of my code attempted to utilize java.util.Optional. From what I understand, it was caused by having surefire's forkModeset to oncefor some reason. No idea why. So I split up my tests in my pom.xml:
我也在使用 Java 7，但遇到了这个错误。据我所知，我的代码都没有尝试使用java.util.Optional. 据我了解，这是由于某种原因forkMode设置了万无一失once。不知道为什么。所以我在我的 pom.xml 中拆分了我的测试：
I run the tests separately because in my case, simply setting forkModeto nonebroke other tests. That being said, you could try setting forkmodeto nonefor everything before tearing apart your pom.xml
我单独运行测试，因为在我的情况下，只是设置forkMode为none破坏其他测试。话虽这么说，你可以尝试设置forkmode到none撕开你的pom.xml之前的一切

As you can see in your stacktrace, there is no java.util.Optionalclass. This class was introduced in Java 8, but you use Java 7. So you have to remove usage of java.util.Optionalor update your Java version.
正如您在堆栈跟踪中看到的那样，没有java.util.Optional类。这个类是在 Java 8 中引入的，但您使用的是 Java 7。因此您必须删除java.util.OptionalJava 版本的使用或更新您的 Java 版本。
