一、前言
今天整理笔记的时候发现有这么个错，重现了一下结果半天没解决。跑去Stack Overflow看了一下M. Deinum的高赞回答(传送门)，跟我的报错是一致，但那老兄问题原因明显不是跟我一类。在度娘又查到一样的错，但答案很多粘贴复制的，搞得我很懵。期间经过多次询问度娘和谷歌，最后通过一个不同于Stack Overflow的方案完美解决。现在将解决方案直接贴出来供大家分享。
二、报错内容
一下是报错内容的部分截取

三、问题分析
首先检查该有的依赖包，配置项，JDK版本等(原谅我病急乱投医)，完全正确。后来在错误中看到最后又提示
Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.21.0:test (default-test) on project music-league-service: There are test failures.开始怀疑是maven配置出了问题，检查了setting的实际配置生效情况，完全没有问题。Kidding me？重新检查项目结构发现有个springboot项目初建时的测试类，MD啥都没写。。。
四、解决方案
1、在测试类RunWith注解哪个地方加上一个@Ignore
2、pom文件最后一个plugins标签，加一个下一级的plugin标签。内容如下：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.4.2</version>
<configuration>
<skipTests>true</skipTests>
</configuration>
</plugin>3、执行mvn命令。命令如下（这个我没试）：
mvn clean package -Dmaven.test.skip=true五、注意事项
注意，如果你在Spring Security配置时打算给cookie弄个私钥，千万不能为空。否则也会报上文报错信息中的后半部分，相似度贼拉高。
