SpringTest框架JUnit单元测试用例获取ApplicationContext实例的方法

转自:http://www.coderli.com/junit-spring-test-applicationcontext

JUnit单元测试用例中使用Spring框架,直接方式如下。

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

想要获取ApplicationContext实例。可以添加了对ApplicationContext的注入

RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/spring/applicationContext.xml" })
public class SpringTest {
 
@Autowired
protected ApplicationContext ctx;

Spring中早已直接提供了更加方便使用的基类:AbstractJUnit4SpringContextTests

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

本人补充:

若在静态类中需要引用只能使用如下方法:

public class TPlatformInfoTest extends TestBase{
    
    private static MyHttpClient TPlatformInfoDispose;
    
    @BeforeClass
    public static void setUpBeforeClass(){
        System.out.println("***********here init first***************");
        TPlatformInfoDispose = new MyHttpClient("platform");
        DataSourceContextHolder.setDbType("ds2");
        ApplicationContext ctx = new ClassPathXmlApplicationContext("classpath:WEB-INF/rest-*.xml");
        pfm = ctx.getBean(TPlatformInfoMapper.class);
        dim = ctx.getBean(TDeviceInfoMapper.class);
    }
