Hibernate 资源文件中定义复杂的自定义sql，可灵活用于自定义的复杂增删改查

在Hibernate 资源文件中定义复杂的自定义sql，可灵活用于自定义的复杂增删改查

此方法不限于以前的hibernate是注解方式还是xml声明实体类。

一 定义包含自定义sql的资源文件：directSql.hbm.xml

Xml代码







<?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">

<hibernate-mapping>

<sql-query
name="mergeTargetScore">

<![CDATA[
update t_duty_target_dtl set target_Scorelevel_Id =:newId where duty_Target_Dtl_Id = :id

]]>
</sql-query>

</hibernate-mapping>

<?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">

<hibernate-mapping>
<sql-query name="mergeTargetScore">
<![CDATA[
update t_duty_target_dtl set  target_Scorelevel_Id =:newId where duty_Target_Dtl_Id = :id
]]>
</sql-query>
</hibernate-mapping>

二 在hibernate。cfg。xml中包含此文件

Xml代码







<hibernate-configuration>

<session-factory>

<property
name="dialect">

org.hibernate.dialect.Oracle9Dialect
</property>

<property
name="connection.url">

jdbc:oracle:thin:@192.168.1.55:1521:orcl
</property>

。。。 <property
name="myeclipse.connection.profile">

ora4sljx
</property>

<mapping
resource="com/jadetrust/sljx/db/directSql.hbm.xml"
/>

<mapping
class="com.jadetrust.sljx.db.domain.TWorkLogTarget"
/>
<mapping
class="com.jadetrust.sljx.db.domain.TReconDtl"
/>

<hibernate-configuration>

<session-factory>
<property name="dialect">
org.hibernate.dialect.Oracle9Dialect
</property>
<property name="connection.url">
jdbc:oracle:thin:@192.168.1.55:1521:orcl
</property>
。。。		<property name="myeclipse.connection.profile">
ora4sljx
</property>

<mapping resource="com/jadetrust/sljx/db/directSql.hbm.xml" />

<mapping class="com.jadetrust.sljx.db.domain.TWorkLogTarget" />
<mapping class="com.jadetrust.sljx.db.domain.TReconDtl" />

三 在java中调用自定义sql

Java代码







public static
void update1(Long whereID, Long destID) {

HibernateSessionFactory.getSession().getTransaction().begin();

Session s = HibernateSessionFactory.getSession();
Query q = s.getNamedQuery("mergeTargetScore");

q.setParameter("id", whereID);

q.setParameter("newId", destID);

q.executeUpdate();

HibernateSessionFactory.getSession().getTransaction().commit();

}

public static void update1(Long whereID, Long destID) {
HibernateSessionFactory.getSession().getTransaction().begin();

Session s = HibernateSessionFactory.getSession();
Query q = s.getNamedQuery("mergeTargetScore");
q.setParameter("id", whereID);
q.setParameter("newId", destID);
q.executeUpdate();

HibernateSessionFactory.getSession().getTransaction().commit();
}
