在老的项目中使用的是Spring3.2，最近我使用了Spring4.0.6进行迁移测试，之前使用的mock的测试没有问题，但是在Spring4中报错如下：

我查看了一下代码和pom.xml的依赖关系，之前Spring3的依赖如下：


        3.2.4.RELEASE
        4.10
    
...
        
            org.springframework
            spring-mock
            2.0.8
            test
        
        
            org.springframework
            spring-test
            ${spring.version}
            test
        

到了Spring4，就需要把spring-mock依赖去除。

希望可以帮助到诸位！
