I have several beans of the same class defined:
@Bean
public FieldDescriptor fullSpotField() {
FieldDescriptor ans = new FieldDescriptor("full_spot", String.class);
return ans;
}
@Bean
public FieldDescriptor annotationIdField() {
FieldDescriptor ans = new FieldDescriptor("annotationID", Integer.class);
return ans;
}
consequently when I autowire them
@Autowired
public FieldDescriptor fullSpotField;
@Autowired
public FieldDescriptor annotationIdField;
I get an exception
NoUniqueBeanDefinitionException: No qualifying bean of type [...FieldDescriptor] is defined: expected single matching bean but found ...
How to autowire by name as it possible in XML config?
You can use @Qualifier
to solve it.
In your case you can make:
@Bean(name="fullSpot")
// Not mandatory. If not specified, it takes the method name i.e., "fullSpotField" as qualifier name.
public FieldDescriptor fullSpotField() {
FieldDescriptor ans = new FieldDescriptor("full_spot", String.class);
return ans;
}
@Bean("annotationIdSpot")
// Same as above comment.
public FieldDescriptor annotationIdField() {
FieldDescriptor ans = new FieldDescriptor("annotationID", Integer.class);
return ans;
}
and subsequently you can inject using:
@Autowired
@Qualifier("fullSpot")
public FieldDescriptor fullSpotField;
@Autowired
@Qualifier("annotationIdSpot")
public FieldDescriptor annotationIdField;
