原因在於maven生成class的目錄被改變,需要重新設置output目錄，

解決辦法一：

打開工程的.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

　　

將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"/>

　　

　解決辦法二：

　　1.打開項目,右擊進入Properties>>JAva Build Path  　　

　　2.勾選下方Allow  output folders for source folders

　　3.設置上方的output folder路徑
