java – Spring Data JPA没有类型的限定bean …找到依赖项

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：

spring-beans-4.0.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-4.0.xsd
            http://www.springframework.org/schema/jee
            http://www.springframework.org/schema/jee/spring-jee.xsd">

    ecurityConfig.xml" />

    fig />
    factorybean">
        ecurity" />
        vendorAdapter">
            vendor.HibernateJpavendorAdapter" />
        MysqL5InnoDBDialect

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：

org.springframework.beans.factory.BeanCreationException: Error

最佳答案

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()}

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

ecurity"
                  entity-manager-factory-ref="myEmf"
                  transaction-manager-ref="transactionManager"/> 

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
