hibernate本机查询映射

Question

我正在尝试创建一个本地命名查询。我看到了链接

result-set-mapping-complex-mappings

<sql-result-set-mapping name="BookAuthorMappingXml">
   <entity-result entity-class="org.thoughts.on.java.jpa.model.Author">
    <field-result name="id" column="authorId"/>
    <field-result name="firstName" column="firstName"/>
    <field-result name="lastName" column="lastName"/>
    <field-result name="version" column="authorVersion"/>
</entity-result>

   <entity-result entity-class="org.thoughts.on.java.jpa.model.Book">
       <field-result name="id" column="id"/>
       <field-result name="title" column="title"/>
       <field-result name="author" column="author_id"/>
       <field-result name="version" column="version"/>
   </entity-result>
</sql-result-set-mapping>

我拥有的列数超过20.是否可以一次性映射所有列

我正在使用hibernate 4.2

你需要的是一个hibernate映射自动生成。 你可以关注mkyong的博客
