java - Jpa存储库 : NoSuchBeanDefinitionException

Question

我使用 spring-data-jpa。没有 Spring Boot。

package ru.spb.repository;

public interface CrudUserRepository extends JpaRepository<User, Integer> {
}

存储库。

 package ru.spb.repository;

@Repository
public class UserRepository {

  @Autowired
  private CrudUserRepository crudRepository;
}

xml 配置文件:

spring-app.xml

<context:component-scan base-package="ru.spb.service"/>
<context:component-scan base-package="ru.spb.repository"/

spring-db.xml:

<context:component-scan base-package="ru.spb.repository" />
<jpa:repositories base-package="ru.spb.repository"/>

在pom中

<spring-data-jpa.version>2.2.0.RELEASE</spring-data-jpa.version>

   <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-jpa</artifactId>
        <version>${spring-data-jpa.version}</version>
    </dependency>

但是我明白了:

 NoSuchBeanDefinitionException: No qualifying bean of type 'ru.spb.repository.user.CrudUserRepository' available: expected at least 1 bean which qualifies as autowire candidate

Answer 1

问题已经解决了。我在 web.xml 的 contextConfigLocation 参数值中添加“classpath:spring/spring-db.xml”:

 <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:spring/spring-app.xml
        classpath:spring/spring-db.xml
    </param-value>
  </context-param>
