When changes made to a detached object need to be persisted, we can use the attachDirty method to reassociate it with Session, and then call the Session&#8217;s flush method to synchronize the changes to the database.<\/p>\n<p>The usage of the attachDirty method is as follows:<\/p>\n<pre class=\"post-pre\"><code><span class=\"hljs-keyword\">public<\/span> <span class=\"hljs-keyword\">void<\/span> <span class=\"hljs-title function_\">attachDirty<\/span><span class=\"hljs-params\">(Object object)<\/span> {\r\n    getSession().saveOrUpdate(object);\r\n}\r\n<\/code><\/pre>\n<p>This method takes an object parameter, which can be either a detached object or a newly created object. Inside the method, we first obtain the current Session object, and then call its saveOrUpdate method to reassociate the object with the Session. The saveOrUpdate method will automatically determine whether to insert or update the object based on its state.<\/p>\n<p>It is important to note that when re-associating an object with the Session using the attachDirty method, the modifications are not immediately synchronized with the database. The changes will only be synchronized with the database when the flush method of the Session is called or when the transaction is committed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In Java, the attachDirty method is a method in the Hibernate framework used to reassociate an object that has been detached from persistence management back to Session management.
