This article mainly shows you the "sample analysis of Hibernate xml mapping in J2EE", which is easy to understand and clear. I hope it can help you solve your doubts. Let me lead you to study and study the "sample analysis of Hibernate xml mapping in J2EE".

For a simple table without a foreign key relationship, the hbm file can be mapped into dom4j's Element without modification. By default, each attribute is mapped to a node; with a foreign key relationship to add embed-xml= "false" to the many-to-one, otherwise it will often cause stack overflows or dom4j attempts to set multiple parent nodes for a node. For Hibernate xml mapping, there are simple tests and complex tests, as shown below.

A simple test:

"- / / Hibernate/Hibernate Mapping DTD 3.0//EN"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" > id > bag > class > hibernate-mapping > "- / / Hibernate/Hibernate Mapping DTD 3.0//EN"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" > id > class > hibernate-mapping >

A more complex test:

"- / / Hibernate/Hibernate Mapping DTD 3.0//EN"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" > id > bag > bag > class > hibernate-mapping > "- / / Hibernate/Hibernate Mapping DTD 3.0//EN"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" > Id > class > hibernate-mapping > the above is all the content of the article "sample Analysis of Hibernate xml Mapping in J2EE" Thank you for reading!
