推荐答案
注释用于配置需要Spring依赖注入的单元测试.
The annotation is used to configure a unit test that required Spring's dependency injection.
来自 Spring参考-10.单元测试 :
为了使单元测试运行批处理作业，框架必须加载作业的ApplicationContext.使用两个注释来触发此操作:
In order for the unit test to run a batch job, the framework must load the job's ApplicationContext. Two annotations are used to trigger this:
@RunWith(SpringJUnit4ClassRunner.class):指示该类应使用Spring的JUnit工具.
@RunWith(SpringJUnit4ClassRunner.class): Indicates that the class should use Spring's JUnit facilities.
@ContextConfiguration(locations = {...}):指示哪些XML文件包含ApplicationContext.
@ContextConfiguration(locations = {...}): Indicates which XML files contain the ApplicationContext.
