我正在用springboot学习java，我不能让junit注解在我的类中工作。
当我放置@runwith（springrunner.class）或@extendwith（springextension.class）时，它甚至没有出现无法解析符号的情况，就好像我没有在pom.xml中添加依赖项一样。
我的完整pom.xml：

我正在使用ide:intelij 2018.2.8
我想做的是：
添加依赖项之后，我转到了build/rebuild项目。
在终端，我已经运行了 mvn clean 以及 mvn install 命令。
在安装时，我遇到了几个错误：

我还需要做些什么来使用junit吗？
