Spring Data JPA No qualifying bean of type ... found for dependency

I have sample test program to test Spring Data JPA, but it seems like the repository doesn't get generated.

My config:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</property>
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="myEmf" />
</bean>
</beans>


User entity:

package com.test.security;

import org.springframework.security.core.CredentialsContainer;
import org.springframework.security.core.userdetails.UserDetails;

@Entity
@Table
public class UserPrincipal implements UserDetails, CredentialsContainer, Cloneable {
private static final long serialVersionUID = 1L;

private long id;
....
}


UserRespository:

package com.test.security;

import org.springframework.data.repository.CrudRepository;

public interface UserRepository extends CrudRepository<UserPrincipal, Long>
{
UserPrincipal getByUsername(String username);
}


UserService:

package com.test.security;

@Service
public class UserService implements UserDetailsService {
@Inject
UserRepository userRepository;

@Override
@Transactional
public UserPrincipal loadUserByUsername(String username) {
UserPrincipal principal = userRepository.getByUsername(username);
// make sure the authorities and password are loaded
principal.getAuthorities().size();
principal.getPassword();
return principal;
}
}


I get this error:

Answer

No qualifying bean of type [com.test.security.UserRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@javax.inject.Inject()}

Grab the spring data jpa namespace (from spring-data-jpa jar)

xmlns:jpa="http://www.springframework.org/schema/data/jpa"
xsi:schemaLocation=
            http://www.springframework.org/schema/data/jpa 
            http://www.springframework.org/schema/data/jpa/spring-jpa.xsd

And use the <repositories> element of the jpa namespace to scan for repositories

<jpa:repositories base-package="com.test.security"
                  entity-manager-factory-ref="myEmf"
                  transaction-manager-ref="transactionManager"/> 

See more at Creating Repository Instances

Here's a snippet stated about the <repositories> tag:

Spring is instructed to scan [com.test.security] and all its subpackages for interfaces extending Repository or one of its subinterfaces. For each interface found, the infrastructure registers the persistence technology-specific FactoryBean to create the appropriate proxies that handle invocations of the query methods

Here's the link for the namespace info

For Java config, you could achieve the same thing with the @EnableJpaRepositories annotation. You can read more about that in the same link as above
