我开发JPA Toplink了使用 JPQL 的应用程序。根据我的研究，JPA 将调用比 JPQL 语句看起来更多的 SQL。

我正在寻找一些 JPQL 分析器工具，例如我可以执行 JPQL 或运行我的应用程序并告诉我正在运行多少实际 SQL。

有没有类似的东西？

更新 按照建议在我的persistence.xml中添加了以下内容，我的Netbean IDE现在显示JPQL生成的实际SQL：D

  <properties>
      <property name="eclipselink.logging.logger" value="JavaLogger"/>
      <property name="toplink.logging.level.sql" value="FINE"/>

I don't think there can be a generic analyzer as the behavior is provider specific. You can however look at the SQL's being executed by enabling appropriate logs of the JPA provider you are using.

Hibernate:

Can't make hibernate stop showing SQL using Spring JPA Vendor Adapter
