我正在尝试将我的命名查询放入orm.xml（与persistence.xml一起放入META-INF中），但是hibernate /
jpa似乎忽略了我的orm.xml。

当我尝试使用em.createNamedQuery（“ myQuery”）创建命名查询时，它返回找不到该查询的信息。

我使用注释，我想在orm.xml中外部化我的命名查询（仅此）。

这是我的persistence.xml：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" version="1.0">

<persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
    <mapping-file>META-INF/orm.xml</mapping-file>

    <class>com.mysite.Account</class>

    <properties>
        <property name="hibernate.cache.provider_class" value="net.sf.ehcache.hibernate.EhCacheProvider" />
        <property name="hibernate.cache.use_query_cache" value="true" />
        <property name="hibernate.cache.use_second_level_cache" value="true" />
        <property name="hibernate.show_sql" value="true" />
        <property name="hibernate.format_sql" value="true" />
        <property name="use_sql_comments" value="false" />
        <property name="hibernate.dialect" value="org.hibernate.dialect.MYSQLDialect" />
        <property name="hibernate.c3p0.min_size" value="5" />
        <property name="hibernate.c3p0.max_size" value="20" />
        <property name="hibernate.c3p0.timeout" value="300" />
        <property name="hibernate.c3p0.max_statements" value="50" />
        <property name="hibernate.c3p0.idle_test_period" value="3000" />

        <property name="hibernate.search.default.directory_provider" value="org.hibernate.search.store.FSDirectoryProvider" />
    </properties>

</persistence-unit>

</persistence>

这是我的orm.xml

<?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_1_0.xsd" version="1.0">

<package>com.mysite</package>

<entity class="Account">
    <sql-result-set-mapping name="nicknames">
        <column-result name="nickname" />
    </sql-result-set-mapping>
    <table name="Account" />
    <named-native-query name="myQuery" result-set-mapping="nicknames">
        <query><![CDATA[select a.nickname from Account a]]>
    </query>
    </named-native-query>
</entity>
</entity-mappings>

我做错了什么？为什么我的orm.xml被忽略？

谢谢
