Question

我正在阅读来自http://www.petrikainulainen.net/programming/spring-framework/spring-data-jpa-tutorial-creating-database-queries-with-named-queries/的petri教程，并决定做一个关于Spring Data JPA的概念证明（POC）。我使用XML创建了一个命名的本机查询，并使用@Query(nativeQuery = true)注释了我的用户存储库。（顺便说一句，Hibernate是我的JPA提供者）。

这是我的UserRepository.java中的方法

@Query(nativeQuery = true)
    public User findByNameAndPasswordXml(@Param("name") String name,@Param("password") String password);

这是我的orm.xml文件，位于src / main / resources / META-INF文件夹下面

<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings
        xmlns="http://java.sun.com/xml/ns/persistence/orm"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_2_0.xsd"
        version="2.0">

    <named-native-query name="User.findByNameAndPasswordXml"
                result-class="org.jrue.poc.springhibernate.domain.User">
        <description>Multiple search query</description>
            <query>
                SELECT 
                    * 
                FROM 
                    M_USER
                WHERE 
                    name = :name
                    AND password = :password
            </query>
    </named-native-query>
</entity-mappings>

为了使Spring Data工作，我使用下面的注释

在持久性配置中指定了位置

@EnableJpaRepositories(basePackages={"org.jrue.poc.springhibernate.repository"}
                        ,namedQueriesLocation="classpath:META-INF/*.xml")

然而，当我执行单元测试时，我收到以下异常，该异常指向我的orm.xml文件。

我使用错误的XML格式吗？我从网上搜索过，发现实体映射没有相关问题。
