我有以下堆栈:
当我部署webapp并启动服务器(Tomcat 7)时,我收到以下错误:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private com.qopuir.repository.UserRepository com.qopuir.service.UserService.userRepository; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.qopuir.repository.UserRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我不明白为什么在自动装配服务期间找不到存储库。有什么想法吗?

这是一个存储库:
package com.qopuir.repository;
import org.springframework.data.mongodb.repository.MongoRepository;
import com.qopuir.domain.User;
public interface UserRepository extends MongoRepository<User, String> {
User findByUsername(String username);
}
这是UserService:
package com.qopuir.service;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.qopuir.repository.RoleRepository;
import com.qopuir.repository.UserRepository;
@Service
public class UserService {
@Autowired
private UserRepository userRepository;
@Autowired
private RoleRepository roleRepository;
//... some methods
}
我不知道这是配置问题还是库版本问题(我使用的是最后一个)

答案 0 :(得分:1)
你的spring-data.xml文件中的mongo:repositories的base-package属性中有一个拼写错误:
<mongo:repositories base-package="com.qoupir.repository" mongo-template-ref="mongoTemplate" />
应该是
<mongo:repositories base-package="com.qopuir.repository" mongo-template-ref="mongoTemplate" />
