[spr开发者_高级运维ing 3.0.5] [jboss 5.1]
I have several classes labeled as @Service
, which implements thet same interface.
For example,
@Service(value="test1")
public TestImpl1 implements Test {}
@Service(value="test2")
public TestImpl2 implements Test {}
Next, I have the following structure
public SomeClass {
@Autowired
@Qualifier("test1")
Test test1;
@Autowired
@Qualifier("test2")
Test test2;
I am getting an exception (at deployment)
10:36:58,277 ERROR [[/test-web]] Servlet /test-web threw load()
exception
org.springframework.beans.factory.NoSuchBeanDefinitionException: No

Anyone know how to solve this?
T.
A few options:
- Use
@Resource(name="test1")
in the injection point - can use the
javax.inject.Qualifer
mechanism. In short - you define an annotation (@Test
) and annotate the annotation with@Qualifier
. Then use@Autowired @Test
on the injection point. - explicitly set qualifiers on the target bean. The docs say show only the xml version
<qualifier />
, but try adding@Qualifier("test1")
on the service definition
Here is the documentation about it
