Java Hibernate加载程序减慢Hibernate SqlQuery,java,sql,performance,hibernate,db2,Java,Sql,Performance,Hibernate,Db2,我在Hibernate 3.6.9 Final下使用DB2数据库时，SqlQuery的时间性能很差。从sql客户端（Squirrel）快速生成sql： 我用的是我自己的结果变压器，但它工作得又好又快（我测量过时间） 我一直在查看周围的时间，发现org.hibernate.loader.loader调用其方法时，所有的时间（大约12秒！！！）都丢失了： 11:21:17,026 DEBUG 127.0.0.1 - MYAPPWEB/api/requests/search - org.hibern

我在Hibernate 3.6.9 Final下使用DB2数据库时，SqlQuery的时间性能很差。从sql客户端（Squirrel）快速生成sql：

我用的是我自己的结果变压器，但它工作得又好又快（我测量过时间）

我一直在查看周围的时间，发现org.hibernate.loader.loader调用其方法时，所有的时间（大约12秒！！！）都丢失了：

正如你在左边的日志中看到的，大约花费了11秒。我在Google上搜索了这个Hibernate类，在这里找到了源代码：并得出结论，加载程序中的getRow（）方法每行进行一次查询（总共175次）以检查ID等等，但我不知道如何禁用此行为，或者为了避免此延迟，我应该修改哪个配置

我会按照人们的要求用配置设置更新帖子，因为我认为所有配置都在几个文件中，而且都很大

提前感谢。

问题不在加载程序中，问题在映射和请求中。请为您的请求添加持久性和代码。我正在使用ResultTransformer（我理解这意味着不应该涉及加载程序），但我正在粘贴主对象的映射。您的主对象非常简单。需要添加请求和请求代码中涉及的所有对象。已添加Java代码和映射，但不应使用映射。问题不在
