（转）Spring编程式事务

• PlatformTransactionManager
• TransactionTemplate

一、使用PlatformTransactionManager

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory">
            <ref bean="sessionFactory"/>
        </property>
    </bean>

    <bean id="txDefinition" class="org.springframework.transaction.support.DefaultTransactionDefinition">
        <property name="propagationBehaviorName" value="PROPAGATION_REQUIRED"></property>
    </bean>

public class TempService {
    private UserDAO userDAO;
    private DeptDAO deptDAO;
    private TransactionDefinition txDefinition;
    private PlatformTransactionManager txManager; 

    public void setUserDAO(UserDAO userDAO) {
       this.userDAO = userDAO;
    }

    public void setDeptDAO(DeptDAO deptDAO) {
       this.deptDAO = deptDAO;
    }

    public void setTxDefinition(TransactionDefinition txDefinition) {
       this.txDefinition = txDefinition;
    }

    public void setTxManager(PlatformTransactionManager txManager) {
       this.txManager = txManager;
    }

    public void addTemp(){
       TransactionStatus status = txManager.getTransaction(txDefinition);//
       try {
           User user = new User();
           Dept dept = new Dept();
           user.setRemark("USER　REMARK");
           dept.setRemark("DEPT REMARK");
           userDAO.save(user);
           deptDAO.save(dept);
           txManager.commit(status);//提交事務
       } catch (Exception e) {
           txManager.rollback(status);
           e.printStackTrace();
       }
    }
}

二、使用TransactionTemplate

<bean id="txTemplate" class="org.springframework.transaction.support.TransactionTemplate">
        <property name="transactionManager" ref="transactionManager"></property>
        <property name="propagationBehaviorName" value="PROPAGATION_REQUIRED"></property>
    </bean>

public class Temp1Service {

    private UserDAO userDAO;
    private DeptDAO deptDAO;
    TransactionTemplate txTemplate;
    public void setUserDAO(UserDAO userDAO) {
       this.userDAO = userDAO;
    }

    public void setDeptDAO(DeptDAO deptDAO) {
       this.deptDAO = deptDAO;
    }

    public void setTxTemplate(TransactionTemplate txTemplate) {
       this.txTemplate = txTemplate;
    }

    public void addTemp(){
       txTemplate.execute(new TransactionCallback(){
           public Object doInTransaction(TransactionStatus status){
              try {
                  User user = new User();
                  Dept dept = new Dept();
                  user.setRemark("USER　REMARK");
                  dept.setRemark("DEPT REMARK");
                  userDAO.save(user);
                  deptDAO.save(dept);
              } catch (Exception e) {
                  status.setRollbackOnly();//
                  e.printStackTrace();
                  return false;
              }
              return true;
           }
       });
    }
}
