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>
