I'm trying to use the default aop proxy provided by Spring, but i'm getting an execption error.
Here is my code: A first class that run the test example.
@EnableAspectJAutoProxy()
@ComponentScan(basePackageClasses = {MyDaoRepository.class, MyService.class,MyAdvices.class})
@Configuration
public class SpringAdvices {
public static void main( String[] args ) {
ApplicationContext ctx = new AnnotationConfigApplicationContext(SpringAdvices.class);
service myService = ctx.getBean(MyService.class);
Person p1 = (Person) ctx.getBean("person");
myService.save(p1);
}
@Bean
public Person person(){
return Person.builder()
.name("Bagna")
.age(52)
.profession(null)
.dateOfBirth(LocalDate.of(1950,12,13))
.build();
}
}
A second class that represent my advices:
@Aspect
@Component
public class MyAdvices {
@Before("execution(boolean *.dao.save(..))")
public void beforesavamethod(){
System.out.println("beforesavamethod");
}
@After("execution(boolean *.dao.save(..))")
public void aftersavamethod(){
System.out.println("aftersavamethod");
}
}
My service and repository classes:
@Service
public class MyService implements service {
@Autowired
MyDaoRepository myDaoRepository;
@Override
public boolean save( Person person ){
return this.myDaoRepository.save(person);
}
@Override
public boolean delete(Person person){
return this.myDaoRepository.delete(person);
}
}
public interface service {
public boolean save( Person person );
public boolean delete( Person person );
}
@Repository
public class MyDaoRepository implements dao {
List<Person> personList = new ArrayList<>();
@Override
public boolean save( Person person ){
return this.personList.add(person);
}
@Override
public boolean delete( Person person ){
return this.personList.remove(person);
}
}
public interface dao {
public boolean save( Person person );
public boolean delete( Person person );
}
The exceptin I'm getting concern the injection of the dao object to the service object.
UnsatisfiedDependencyException: Error creating bean with name 'myService': Unsatisfied dependency expressed through field 'myDaoRepository'; nested exception is org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'myDaoRepository' is expected to be of type 'aop.question_005.dao.MyDaoRepository' but was actually of type 'com.sun.proxy.$Proxy22'
I can solve this problem by enabling the GCLIB mechanism, but i'm wondering how can i solve this problem using the same JDK dynamic proxy?
