我有测试Spring Data JPA的示例测试程序,但似乎没有生成存储库.
我的配置：
用户实体：
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
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;
}
}
我收到此错误：

抓取spring数据jpa命名空间(来自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
并使用< repositories>用于扫描存储库的jpa命名空间的元素
在Creating Repository Instances查看更多信息
这是一个关于< repositories>的片段.标签：
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
这是namespace info的链接
对于Java配置,您可以使用@EnableJpaRepositories注释实现相同的功能.您可以在同一个link as above中阅读更多相关信息
