问题描述

我有以下堆栈:

  • Spring MVC Web应用程序
  • Spring Data MongoDB

部署Webapp并启动服务器(Tomcat 7)时，出现以下错误:

When I deploy the webapp and start server (Tomcat 7) I'am getting the following error :

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.有什么主意吗?

I don't understand why Repositories are not found during autowiring of Services. Any idea?

这是存储库之一:

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:

Here is the 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(我正在使用最后一个)

I don't know if it is a problem of configuration or a problem with version of libraries (I am using the last ones)

推荐答案

您的spring-data.xml文件中mongo:repositories的base-package属性中有一个错字:

You have a typo in the base-package attribute of mongo:repositories in your spring-data.xml file:

<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" />
