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;
    }
}
