我就是在ApplicationContextConfig(写bean的配置类)配置了：

@Bean

    public PersistenceAnnotationBeanPostProcessor persistenceAnnotationBeanPostProcessor(){

        return new PersistenceAnnotationBeanPostProcessor();

    }



    //使用Hibernate作为JPA实现

    @Bean

    public JpaVendorAdapter jpaVendorAdapter(){

        HibernateJpaVendorAdapter hibernateJpaVendorAdapter = new HibernateJpaVendorAdapter();

        hibernateJpaVendorAdapter.setDatabase(Database.MYSQL);

        hibernateJpaVendorAdapter.setShowSql(true);

        hibernateJpaVendorAdapter.setGenerateDdl(false);

        hibernateJpaVendorAdapter.setDatabasePlatform("org.hibernate.dialect.MySQLDialect");

        return hibernateJpaVendorAdapter;

    }



    //配置使用容器管理类型的JPA

    @Bean

    public LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean(){

        LocalContainerEntityManagerFactoryBean localContainerEntityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();

        localContainerEntityManagerFactoryBean.setDataSource(dataSource());

        localContainerEntityManagerFactoryBean.setJpaVendorAdapter(jpaVendorAdapter());

        localContainerEntityManagerFactoryBean.setPackagesToScan("repository");

        return localContainerEntityManagerFactoryBean;

    }

然后又写了个JpaConfiguration的配置类：

@Configuration

@EnableJpaRepositories(basePackages = "persistence")

public class JpaConfiguration {

}

求解为什么初始化不了那个bean，idea没报错，包应该没什么问题啊，而且错误提示的java.lang.ClassNotFoundException: org.springframework.context.index.CandidateComponentsIndexLoader，好像根本不存在这个包这个类啊？？
