hibernate多对多映射文件详解（一）

1、仓库表属性

public class WarehouseNew implements java.io.Serializable {

// Fields
 private static final long serialVersionUID = 1L;
 private Integer id;
 private Integer wid;
 private String wname;
 private String aid;
 private String city;
 private String address;
 private Integer client_id;
 private String backup1;
 private String backup2;
 //state 0:表示采集器没有数据  1:状态正常  2:告警状态   3:异常状态
 private Integer state;
 private Set<Linkman> linkman = new HashSet<Linkman>();

}

2、仓库表映射文件

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<!--
    Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping>
    <class name="com.sinosoft.model.WarehouseNew" table="WAREHOUSE_NEW" schema="POTATO">
        <id name="id" type="java.lang.Integer">
            <column name="ID" precision="22" scale="0" />
             <generator class="sequence">
              <param name="sequence">WAREHOUSE_ID_SEQ</param>
            </generator>
        </id>
        <property name="wid" type="java.lang.Integer">
            <column name="WID" precision="22" scale="0" />
        </property>
        <property name="wname" type="java.lang.String">
            <column name="WNAME" length="100" />
        </property>
        <property name="aid" type="java.lang.String">
            <column name="AID" length="10" />
        </property>

            <column name="CITY" length="50" />
        </property>
        <property name="address" type="java.lang.String">

        </property>
        <property name="client_id" type="java.lang.Integer">
            <column name="CLIENT_ID" precision="22" scale="0" />
        </property>
        <property name="backup1" type="java.lang.String">
            <column name="BACKUP1" length="50" />
        </property>
        <property name="backup2" type="java.lang.String">
            <column name="BACKUP2" length="50" />
        </property>
        <set name="linkman" table="L_W_TABLE" cascade="all" inverse="false" lazy="true">
         <key column="warehousenewid" not-null="true"></key>
         <many-to-many column="linkmanid" class="com.sinosoft.model.Linkman"></many-to-many>
        </set>
        
      
    </class>
</hibernate-mapping>

3、联系人表属性

public class Linkman implements java.io.Serializable{
 // Fields
 private static final long serialVersionUID = 1L;
 private Integer id;
 private String lname;
 private String tel1;
 private String tel2;
 private String tel3;
 private Integer sex;
 private Integer ltype;
 private String email;
 private String backup1;
 private String backup2;
 
 private Set warehouseNews = new HashSet();

}
