已与地址为 ''127.0.0.1:61655'，传输: '套接字'' 的目标虚拟机断开连接
进程已结束，退出代码为 -1
原因：缺少okio的包或者是okio的版本不对。这个是跟okhttp一起的
我的配置是
<dependency>
<groupId>com.squareup.okhttp3</groupId>
<artifactId>okhttp</artifactId>
<version>4.12.0</version>
</dependency>
<dependency>
<groupId>com.squareup.okio</groupId>
<artifactId>okio</artifactId>
<version>3.7.0<</version>
</dependency>以下是springboot才会出现的问题，非springboot的工程不会出这些问题
3、selenium的版本混乱
我配置的版本明明是3.141.59
<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.141.59</version>
</dependency>但是maven下载下来的版本有4.1.4这个版本

原因：跟springboot的版本发生冲突了。具体看我的截图
到这里，基本上就可以明确问题的原因了。
spring-boot-dependencies中默认是带着selenium的配置的，我这里的版本恰好是4.1.4。
我在module中虽然设置了版本，但是实际上并没有覆盖sprongboot的默认配置。
那么我们要做的就是覆盖掉springboot默认的版本
回到我们的单独的module的pom文件中，在properties标签中加上这个。写法是固定的，跟spring-boot-dependencies中是一样的
<selenium.version>3.141.59</selenium.version>
这个时候再看看此时的版本，就全部统一起来了
问题3和问题4就都可以解决了。在测试就不报错了
