原因在于maven生成class的目录被改变,需要重新设置output目录，

解决办法一：

打开工程的.classpath文件：

 

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" path="src/main/java"/>
	<classpathentry kind="src" path="src/main/config"/>
	<classpathentry kind="src"  path="src/test/java"/>
                .......
</classpath

　　

将output="target/test-classes"加上就好用了

　　

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" path="src/main/java"/>
	<classpathentry kind="src" path="src/main/config"/>
	<classpathentry kind="src"  output="target/test-classes" path="src/test/java"/>

　　

　解决办法二：

　　1.打开项目,右击进入Properties>>JAva Build Path  　　

　　2.勾选下方Allow  output folders for source folders

　　3.设置上方的output folder路径
