spring-test跟junit结合单元测试获取ApplicationContext实例的方法

步骤

1、继承AbstractJUnit4SpringContextTests

2、引入ApplicationContext

 

示例代码：（可以根据name或者类型获取bean）

 import org.junit.runner.RunWith;
 import org.springframework.test.context.ContextConfiguration;
 import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
 import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

 @RunWith(SpringJUnit4ClassRunner.class)
 @ContextConfiguration(locations = { "/spring/applicationContext.xml" })
 public class SpringTest extends AbstractJUnit4SpringContextTests {

     @Autowired
     protected ApplicationContext ctx;

     public <T> T getBean(Class<T> type) {
         return applicationContext.getBean(type);
     }

     public Object getBean(String beanName) {
         return applicationContext.getBean(beanName);
     }

     protected ApplicationContext getContext() {
         return applicationContext;
     }
 }
