我有一个使用注释@RunWith(SpringJUnit4ClassRunner.class) 的单元测试用例。
spring 2.5.6 和 @RunWith(SpringJUnit4ClassRunner.class) 注释一切正常。但是当我将 spring 版本转换为 3.2.2-Release 并且如果使用 @RunWith(SpringJUnit4ClassRunner.class) 它会引发以下异常
java.lang.NoSuchFieldError: NULL

但是使用 spring 3.2.2-Release 并且当不使用 @RunWith(SpringJUnit4ClassRunner.class) 时它可以正常工作。
我的 pom 中有以下依赖项
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
</dependency>
不知道怎么回事！！
