我正在尝试为spring引导编写集成测试。我希望服务器应该在测试期间启动，这样我就可以从测试代码连接客户机。使用java1.7。在作为maven测试运行时，我会遇到异常。(来自控制台)

我也在使用Java 7，我遇到了这个错误。据我所知，我的代码中没有一个试图利用java.util.Optional。据我所知，这是由于出于某种原因，将forkMode设置为once所致。不知道为什么。因此，我在我的pom.xml中拆分了我的测试：

代码语言：javascript
运行
复制
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <inherited>true</inherited>
      <configuration>
        <skip>true</skip>
      </configuration>
      <executions>
        <execution>
          <id>everything-but-problematic-test</id>
          <phase>test</test>
          <goals>
            <goal>test</goal>
          </goals>
          <configuration>
            <skip>false</skip>
            <forkMode>once</forkMode>
            <excludes>
              <exclude>**/*problematic-test.java</exclude>
            </excludes>
          </configuration>
        </execution>
        <execution>
          <id>problematic-test</id>
          <phase>test</test>
          <goals>
            <goal>test</goal>
          </goals>
          <configuration>
            <skip>false</skip>
            <forkMode>none</forkMode>
            <includes>
              <include>**/*problematic-test.java</include>
            </includes>
          </configuration>
        </execution>
      </executions>
    </plugin>

我单独运行测试，因为在我的示例中，简单地将forkMode设置为none会破坏其他测试。话虽如此，您可以尝试将forkmode设置为none，然后再撕毁pom.xml。

正如您在堆栈跟踪中所看到的，没有java.util.Optional类。这个类是在Java 8中引入的，但是您使用的是Java 7，所以您必须删除java.util.Optional的使用或更新您的Java。
