java–@Autowired注释无法在JUnit类中注入bean

我的考试班：

public class myTest extends TestCase{
@Autowired
BeanClass beanObject
public void beanTest()
{
Classdata data = beanObject.getMethod();
}
}


我在行处获得空指针异常：

Classdata data = beanObject.getMethod();


beanObject.getMethod();精确地给出了nullpointer异常

我应该如何使我的Junit类中的字段beanObject自动装配,以便我可以使用“BeanClass”类中的方法？

复制自评论：

in plain terms.. beanClass is an
interface which has certain methods..

i have tagged that beanClass with

@Service("beanObject")

annotation..that banClass is

implemented by beanClassImpl class

which has the method implementations..

i need to use those implementations in

my testClass to get the data to be

compared.. for that i am doing

@Autowired beanClass beanObject in

my testClass.. m i going terribly

wrong somewhere?

解决方法:

您可能需要使用以下注释来装饰测试：

@ContextConfiguration(locatiOns= {/* your xml locations here */})
@RunWith(SpringJUnit4ClassRunner.class)


或者,如果使用JUnit 3.x,则应从AbstractJUnit38SpringContextTests扩展

参考：TestContext support classes

更新：问题似乎是无法找到上下文文件(请参阅注释中的讨论).

不要注释接口,注释实现类.使用@Service注释接口无效！
