Hibernate 多对一

Hibernate的many-to-one 关联。

具体看配置文件：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
 
<hibernate-mapping package="com.java1234.model">
 
	<class name="Student" table="t_student">
		<id name="id" column="stuId">
			<generator class="native"></generator>
		</id>
 
		<property name="name" column="stuName"></property>
		<!-- 这里的many就是指的改xml对应的类Student，而one就指的班级Class -->
		<many-to-one name="c" column="classId" class="com.java1234.model.Class" cascade="save-update"></many-to-one>
	</class>
 
</hibernate-mapping>
