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);
}
