我正在使用 Spring Data JPA 并尝试像这样运行查询：

@Query(value="select i.content from Item i where i.itemOrder = :order")
List<String> findContentByItemOrder(@Param("order")Integer itemOrder);

但它抛出异常：org.hibernate.hql.internal.ast.QuerySyntaxException：项目未映射[从项目 i 中选择 i.content i.itemOrder = :order]

所以当我运行这个时：

@Query(value="select i.content from package.name.Item i where i.itemOrder = :order")
List<String> findContentByItemOrder(@Param("order")Integer itemOrder);

一切都按预期进行。我的配置：

@Bean
public EntityManagerFactory entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();

    HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
    vendorAdapter.setGenerateDdl(true);

    factory.setJpaVendorAdapter(vendorAdapter);
    factory.setPackagesToScan("package.name");
    factory.setDataSource(dataSource);
    factory.setJpaProperties(createProperties());
    factory.afterPropertiesSet();

    return factory.getObject();
}

private Properties createProperties(){
    Properties properties = new Properties();
    properties.setProperty("hibernate.dialect", "org.hibernate.dialect.PostgreSQLDialect");
    properties.setProperty("hibernate.show_sql", "true");
    properties.setProperty("hibernate.hbm2ddl.auto", "validate");

    return properties; 
}

我正在使用：Spring Data Jpa 1.3.1.RELEASE、Hiberante 4.2、Spring 3.2.1

问题是我不想在我的 Query.How 设置 Spring Data JPA 以自动查找映射类的每个类名都放置package.name ？
