autowired issue

[collinm]

hi

i'm beginning with spring 3.0

i try to use annotation to reduce xml file

i get:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'supervisionController': Injection of autowired dependencies failed; 

nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.h23v.service.IUserService com.h23v.controller.UserController.userService; 

nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.h23v.service.IUserService] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

my controler class

@Controller
public class UserController {
    
    @Autowired    
    private IUserService userService; 
	...
}

my service class

@Service
public class UserService implements IUserService {

    @Autowired
    private IUserDao userDao;
    ...
}

my dao class

@Repository
public class UserDaoImpl extends JdbcDaoSupport  implements IUserDao{
    @Override
    public List<User> getAllUser() {
	...
	}
    ...
}

a part of my dispatch servlet file

<context:component-scan base-package="com.h23v.controller"/>
<context:annotation-config/>

a part of my application context file

	<bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
          p:location="/WEB-INF/jdbc.properties" />
    
    <bean id="dataSource"
          class="org.springframework.jdbc.datasource.DriverManagerDataSource"
          p:driverClassName="${jdbc.driverClassName}"
          p:url="${jdbc.url}"
          p:username="${jdbc.username}"
          p:password="${jdbc.password}" />

i don't understand the error

any idea

thanks

apart from

<context:annotation-config />


you also need to add this

<context:component-scan base-package="your.package.name.*" />
<context:component-scan base-package="your.other.package.here*" />

[smadarapu]

Sorry, i just noticed that you already have that.

[smadarapu]

The package you provided in your component-scan doesn't match withe package that your bean is in.

ok i changed for

<context:component-scan base-package="com.h23v.*"/>
<context:annotation-config/>

now i get this error

 nested exception is java.lang.IllegalArgumentException: 'dataSource' or 'jdbcTemplate' is required

spring is not supposed to manage automatically dataSource, jdbcTemplate when autowired is used?

i tried to add in application-context without success

<bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">   
        <property name="dataSource" ref="dataSource" />   
</bean>

any idea?
