Hibernate natively maps blob columns to java.sql.Blob. However, it's sometimes useful to read the whole blob into memory and deal with it as a byte array.

One approach for doing this to create a new UserType as follows.

package mypackage;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Types;
import java.sql.Blob;
import cirrus.hibernate.Hibernate;
import cirrus.hibernate.HibernateException;
import cirrus.hibernate.UserType;
public class BinaryBlobType implements UserType
{
public int[] sqlTypes()
{
return new int[] { Types.BLOB };
}
public Class returnedClass()
{
return byte[].class;
}
public boolean equals(Object x, Object y)
{
return (x == y)
|| (x != null
&& y != null
&& java.util.Arrays.equals((byte[]) x, (byte[]) y));
}
public Object nullSafeGet(ResultSet rs, String[] names, Object owner)
throws HibernateException, SQLException
{
Blob blob = rs.getBlob(names[0]);
return blob.getBytes(1, (int) blob.length());
}
public void nullSafeSet(PreparedStatement st, Object value, int index)
throws HibernateException, SQLException
{
st.setBlob(index, Hibernate.createBlob((byte[]) value));
}
public Object deepCopy(Object value)
{
if (value == null) return null;
byte[] bytes = (byte[]) value;
byte[] result = new byte[bytes.length];
System.arraycopy(bytes, 0, result, 0, bytes.length);
return result;
}
public boolean isMutable()
{
return true;
}
}

The BinaryBlobType will convert a blob into a byte array and back again.

Here's how to use it. First, define an entity that contains a byte[] property:

public class ImageValue
{
private long id;
private image byte[];
public long getId() { return id; }
public void setId(long id) { this.id = id; }
public byte[] getImage() { return image; }
public void setImage(byte[] image) { this.image = image; }
}

Then map a blob column onto the byte[] property:

<class name="ImageValue" table="IMAGE_VALUE">
<id name="id/>
<property name="image" column="IMAGE" type="mypackage.BinaryBlobType"/>
</class>

Notes:

1) Blobs aren't cachable. By converting the blob into a byte array, you can now cache the entity.

2) This approach reads the whole blob into memory at once.

3) The above type is known to work for reading blobs out of the db. Other usage patterns might also work.

Comments (GK)

I changed isMutable() to return true, since an array is a mutable object.

The use of setBlob() will work on some drivers, but not all. I think its more portable to use setBytes() or even setBinaryStream().

comments (db)

db's comment above was right, setBlob() didn't work on Oracle, I used setBytes().

comments (Chad Woolley)

Below is a modified nullsafeset() that i needed to use to get it to work with tomcat 4.1.27 & oracle 8/9i - the normal calls don't work through the tomcat/dbcp connection pool wrapper objects... (this caused me great pain)

pls note that the setBytes() doesn't seem to work with oracle driver & hibernate

d.birch@eclipsegroup.com.au

public void nullSafeSet(PreparedStatement st, Object value, int index)
throws HibernateException, SQLException
{
if(st instanceof org.apache.commons.dbcp.DelegatingPreparedStatement &&
((org.apache.commons.dbcp.DelegatingPreparedStatement)st).getDelegate()
instanceof oracle.jdbc.OraclePreparedStatement)
{
oracle.sql.BLOB blob = oracle.sql.BLOB.createTemporary(
((org.apache.commons.dbcp.PoolableConnection)st.getConnection()).getDelegate(), false, oracle.sql.BLOB.DURATION_SESSION);
blob.open(BLOB.MODE_READWRITE);
OutputStream out = blob.getBinaryOutputStream();
try
{
out.write((byte[])value);
out.flush();
out.close();
}
catch(IOException e)
{
throw new SQLException("failed write to blob" + e.getMessage());
}
blob.close();
((oracle.jdbc.OraclePreparedStatement)((org.apache.commons.dbcp.DelegatingPreparedStatement)st).getDelegate()).setBLOB(index, blob);
}
else
{
st.setBlob(index, Hibernate.createBlob((byte[]) value));
}
}
//and.. note the null check, oracle drivers return a null blob...
public Object nullSafeGet(ResultSet rs, String[] names, Object owner)
throws HibernateException, SQLException
{
final Blob blob = rs.getBlob(names[0]);
return blob != null?blob.getBytes(1, (int)blob.length()):null;
}

/ comments Vanitha

I had to use the user type to save pdfs as oraBLOBs in oracle 91 database. nullsafeSet

needed a sligh modification , or else ther was a classcastexception. Used oracle Blob instead of Hibernate Blob type and it works.

 public void nullSafeSet(PreparedStatement st, Object value, int index)
throws HibernateException, SQLException
{
oracle.sql.BLOB t_blob = oracle.sql.BLOB.createTemporary(((org.jboss.resource.adapter.jdbc.WrappedConnection) st.getConnection()).getUnderlyingConnection(),
false, oracle.sql.BLOB.DURATION_SESSION);
OutputStream t_out = null;
t_blob.open(BLOB.MODE_READWRITE);
t_out = t_blob.getBinaryOutputStream();
try
{
t_out.write((byte[]) value);
t_out.flush();
t_out.close();
}
catch (IOException e)
{
throw new SQLException("failed write to blob" + e.getMessage());
}
t_blob.close();
st.setBlob(index, t_blob);
}

本篇主要讲解在未使用其他框架(Spring)整合情况?独立ZActiveMQ,使用JMS规范q行消息通信?br />

     下面是JMS规范基本的接口和实现
     JMS Common Interfacse PTP-Specific Interface   Pub/Sub-specific interfaces
     ConnectionFactory     QueueConnectionFactory   TopicConnectionFactory
     Connection            QueueConnection          TopicConnection
     Destination           Queue                    Topic
     Session               QueueSession             TopiSession
     MessageProducer       QueueSender              TopicPublisher
     MessageConsumer       QueueReceiver/QueueBrwer TopicSubscriber


     ?使用Queue

         下面以ActiveMQ example的代码ؓ主进行说?br />         
        1. 使用ActiveMQ的ConnectionQConnectionFactory 建立q接,注意q里没有用到pool
       

java 代码
  1. import org.apache.activemq.ActiveMQConnection   
  2. import org.apache.activemq.ActiveMQConnectionFactory   

        //建立Connection

java 代码
  1. protected Connection createConnection() throws JMSException, Exception {   
  2.      ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(user, pwd, url);   
  3.      Connection connection = connectionFactory.createConnection();   
  4.      if (durable && clientID!=null) {   
  5.          connection.setClientID(clientID);   
  6.      }   
  7.      connection.start();   
  8.      return connection;   
  9.     }  

        //建立Session
  

java 代码
  1. protected Session createSession(Connection connection) throws Exception {   
  2.          Session session = connection.createSession(transacted, ackMode);   
  3.          return session;   
  4.         }   

        2。发送消息的代码
 //建立QueueSession
 

java 代码
  1. protected MessageProducer createProducer(Session session) throws JMSException {   
  2.         Destincation destination = session.createQueue("queue.hello");   
  3.         MessageProducer producer = session.createProducer(destination);   
  4.         producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);   
  5.            
  6.         if( timeToLive!=0 )   
  7.             producer.setTimeToLive(timeToLive);   
  8.         return producer;   
  9.         }   

         //使用Producer发送消息到Queue
    

java 代码
  1. producer.send(message);   

       
        3。接受消?在JMS规范里面,你可以?br />   

java 代码
  1. QueueReceiver/QueueBrowser直接接受消息,但是更多的情况下我们采用消息通知方式,卛_现MessageListener接口   
  2.  public void onMessage(Message message) {   
  3.  //process message   
  4.  }   
  5.           
  6.  //set MessageListner ,receive message   
  7.  Destincation destination = session.createQueue("queue.hello");   
  8.  consumer = session.createConsumer(destination);   
  9.  consumer.setMessageListener(this);   

       
        以上是使用jms queue发送接受消息的基本方式

 
     ?Topic

        1. 建立q接
   

java 代码
  1. protected Connection createConnection() throws JMSException, Exception {      
  2.         ActiveMQConnectionFactory connectionFactory = new ActiveMQConnectionFactory(user, pwd, url);      
  3.         Connection connection = connectionFactory.createConnection();      
  4.         //如果你要使用DurableSubScription 方式,你必Mؓconnection讄一个ClientID      
  5.         if (durable && clientID!=null) {      
  6.             connection.setClientID(clientID);      
  7.         }      
  8.         connection.start();      
  9.         return connection;      
  10.        }      

       2. 建立Session

java 代码
  1. protected Session createSession(Connection connection) throws Exception {      
  2.         Session session = connection.createSession(transacted, ackMode);      
  3.         return session;      
  4.         }    

 3.创徏Producer 发送消息到Topic   
       

java 代码
  1. //create topic on  session   
  2.        topic = session.createTopic("topic.hello");   
  3.  producer = session.createProducer(topic);   
  4.        //send message    
  5.        producer.setDeliveryMode(DeliveryMode.NON_PERSISTENT);   
  6.  producer.send(message);   


 4.创徏Consumer接受消息(基本上和Queue相同)

java 代码
  1. Destincation destination  = session.createTopic("topic.hello");      
  2. MessageConsumer consumer = session.createConsumer(destination);      
  3. consumer.setMessageListener(this);      
  4.            
  5.      //如果你用的是Durable Subscription方式,你必d建立connection的时?nbsp;     
  6.      //讄ClientID,而且建立comsumer的时候用createDurableSubscriberҎ,Z指定一个consumerName?nbsp;     
  7.  //connection.setClientID(clientId);      
  8.  //consumer = session.createDurableSubscriber((Topic) destination, consumerName);   

       
 ?q接ActiveMQ的方?br />         ActiveMQConnectionFactory 提供了多U连接到Broker的方?a title="ActiveMQq接协议" >activemq.apache.org/uri-protocols.html

 常见的有
 vm://host:port     //vm
 tcp://host:port    //tcp
 ssl://host:port    //SSL

]]>ActiveMQ 实践之\(一) 启动你的ActiveMQ http://www.aygfsteel.com/hk2000c/archive/2007/11/16/161070.htmlhk2000chk2000cFri, 16 Nov 2007 09:05:00 GMThttp://www.aygfsteel.com/hk2000c/archive/2007/11/16/161070.htmlhttp://www.aygfsteel.com/hk2000c/comments/161070.htmlhttp://www.aygfsteel.com/hk2000c/archive/2007/11/16/161070.html#Feedback0http://www.aygfsteel.com/hk2000c/comments/commentRss/161070.htmlhttp://www.aygfsteel.com/hk2000c/services/trackbacks/161070.html     E度: 入门


    一.安装ActiveMQ

       首先去http://activemq.apache.org/download.html 下蝲最新版?.1.0release (http://activemq.apache.org/activemq-410-release.html),
    解压apache-activemq-4.1-incubator.zip(或者apache-activemq-4.1-incubator.tar.gz)目录如下:
      
       +bin       (windows下面的bat和unix/linux下面的sh)
       +conf      (activeMQ配置目录,包含最基本的activeMQ配置文g)
       +data      (默认是空?
       +docs      (index,replease版本里面没有文档,-.-b不知道ؓ啥不?
       +example   (几个例子
       +lib       (activemMQ使用到的lib)
       -apache-activemq-4.1-incubator.jar  (ActiveMQ的binary)
       -LICENSE.txt      
       -NOTICE.txt       
       -README.txt
       -user-guide.html


       你可以用bin\activemq.bat(activemq) 启动,如果一切顺?你就会看见类g面的信息
      (l节可能不一?比如路径,或者jmx,jdbc信息)

  ACTIVEMQ_HOME: D:\java\framework_and_lib\activemq\apache-activemq-4.1-incubator\

         *。几个小提示
  1. q个仅仅是最基础的ActiveMQ的配|?很多地方都没有配|因此不要直接用这个配|用于生产系l?br />   2. 有的时候由于端口被占用,DActiveMQ错误,ActiveMQ可能需要以下端?099(JMX),61616(默认的TransportConnector)
  3. 如果没有物理|卡,或者MS的LoopBackAdpater Multicast会报一个错?/p>

     ? 试你的ActiveMQ
       
          ׃ActiveMQ是一个独立的jms provider,所以我们不需要其他Q何第三方服务器就可以马上做我们的试?~译
     example目录下面的程?br />          
   ProducerTool/ConsumerTool 是JMS参考里面提到的典型应用,Producer产生消息,Consumer消费消息
   而且q个例子q可以加入参数帮助你试刚才启动的本地ActiveMQ或者是q程的ActiveMQ

   ProducerTool [url] broker的地址,默认的是tcp://localhost:61616
                [true|flase] 是否使用topic,默认是false
         [subject] subject的名?默认是TOOL.DEFAULT
         [durabl] 是否持久化消?默认是false
         [messagecount] 发送消息数?默认?0
         [messagesize] 消息长度,默认?55
         [clientID] durable为true的时?需要配|clientID
         [timeToLive] 消息存活旉
         [sleepTime] 发送消息中间的休眠旉
         [transacte]  是否采用事务

         
          ConsumerTool [url] broker的地址,默认的是tcp://localhost:61616
                [true|flase] 是否使用topic,默认是false
         [subject] subject的名?默认是TOOL.DEFAULT
         [durabl] 是否持久化消?默认是false
         [maxiumMessages] 接受最大消息数?0表示不限?br />        
         [clientID] durable为true的时?需要配|clientID
        
         [transacte]  是否采用事务
         [sleepTime]  接受消息中间的休眠时?默认?,onMeesageҎ不休?br />          [receiveTimeOut] 接受时

          我们q样可以使用:
   java -classpath .\apache-activemq-4.1-incubator.jar;example\bin ProducerTool  tcp://192.168.3.142:61616 test.mysubject
   java -classpath .\apache-activemq-4.1-incubator.jar;example\bin ConsumerTool  tcp://192.168.3.142:61616 test.mysubject

   当然你可以用上面的参数q行更复杂的试,持久,事务

   如果出现下面的信?恭喜?你的ActiveMQ已经能够工作?br />         
  Connecting to URL: tcp://192.168.3.142:61616
  Publishing a Message with size 255 to queue: TOOL.DEFAULT
  Using non-durable publishing
  Sleeping between publish 0 ms
  Sending message: Message: 0 sent at: Thu Feb 08 15:05:34 CST 2007  ...
  Sending message: Message: 1 sent at: Thu Feb 08 15:05:34 CST 2007  ...
         。。。。。。。?/p>


  Connecting to URL: tcp://192.168.3.142:61616
  Consuming queue: test.mysubject
         Using non-durable subscription
         Received: Message: 0 sent at: Thu Feb 08 14:51:34 CST 2007  ...
         Received: Message: 1 sent at: Thu Feb 08 14:51:34 CST 2007  ...
  。。。?/p>


         ?结
     
      我们已经下蝲,启动,q且用程序测试了我们的ActiveMQ,而后面将在这个能跑得ActiveMQq一步的C?一步一步展CActiveMQ的高U特性?/p>

先看web.xml里面关于activemq的invoke

<!--调用activemq -->
    <context-param >
     <param-name>brokerURI </param-name >
     <param-value>/WEB-INF/activemq.xml </param-value >
    </context-param>
   
    <listener>

    <context-param >
     <param-name>brokerURI </param-name >
     <param-value>/WEB-INF/activemq.xml </param-value >
    </context-param>
   
    <listener>
       <listener-class>org.activemq.web.SpringBrokerContextListener</listener-class>
    </listener>

然后是在上下文中定义的JmsTemplate和activemq监听

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">
<beans>

<!--JMS Template-->
    <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
        <property name="connectionFactory">
      <bean class="org.activemq.ActiveMQConnectionFactory">
       <property name="brokerURL">
        <value>tcp://localhost:61616</value>
       </property>
      </bean>
     </property>
     
      <property name="defaultDestinationName" value="Hello.Queue"/>
    </bean>

   <bean id="activeMQContainer" class="org.activemq.jca.JCAContainer">
     <property name="workManager">
       <bean id="workManager" class="org.activemq.work.SpringWorkManager"/>
     </property>

     <property name="resourceAdapter">
       <bean id="activeMQResourceAdapter"
           class="org.activemq.ra.ActiveMQResourceAdapter">
         <property name="serverUrl" value="tcp://localhost:61616"/>
       </bean>
     </property>
   </bean>
 

  <!--监听 Message 的Message Driven POJO-->
    <bean id="HelloPlaceBean" class="com.officetao.jms.HelloMDP" autowire="byName"/>

  <bean id="HelloMDP" factory-method="addConnector" factory-bean="activeMQContainer">
     <property name="activationSpec">
       <bean class="org.activemq.ra.ActiveMQActivationSpec">
         <property name="destination" value="Hello.Queue"/>
         <property name="destinationType" value="javax.jms.Queue"/>
       </bean>
     </property>
     <property name="ref" value="HelloBean" />
   </bean>

</beans>

建立一个模拟的发送消息的beanQ内容如?/font>

final String mailContent = "新增单号?000的订? 金额";
  try {
            if (jmsTemplate != null)
                jmsTemplate.send(new MessageCreator() {
                    public Message createMessage(Session session)
                            throws JMSException {
                        Message message = session.createMessage();
                        message.setStringProperty("content", mailContent);
                        return message;
                    }
                });
        }
        catch (Exception e) {
            logger.error("JMS error when place order:", e);
        }

最后就是监听消息然后采取行动的bean


public class HelloMDP implements MessageListener {


 
 public void onMessage(javax.jms.Message arg0) {
  
  try   {  
            subAuthenticator   subauth   =   new   subAuthenticator("邮箱登陆?,"密码");//smtp验证   authenticator  
            props.put("mail.smtp.host","smtp.163.com");  
            props.put("mail.smtp.auth","true");  
            session   =   Session.getInstance(props,subauth);  
            MimeMessage   message   =   new   MimeMessage(session);  
            message.setRecipient(Message.RecipientType.TO,new   InternetAddress("接收邮g的邮?/font>"));  
            message.setFrom(new   InternetAddress("自己的邮?/font>"));  
            message.setSubject("ok");  
            message.setText("if you see it,it works!");  
            Transport.send(message);
        }  
        catch(AuthenticationFailedException   e1){  
            System.out.println("SMTP认证出错Q?);  
        }  
        catch   (MessagingException   e)   {  
            e.printStackTrace();
        }  
 
}

public   static   Properties   props   =   System.getProperties();
public   static   Session   session   =   null;  

/**  
*此内部类定义了smtp认证Ҏ  
*/  
public   class   subAuthenticator   extends   Authenticator{  
private   String   userName;  
private   String   password;  
public   subAuthenticator(String   user,String   pass){  
    userName=user;  
    password=pass;  
}  
public   PasswordAuthentication   getPasswordAuthentication(){  
    return   new   PasswordAuthentication(userName,password);  
}

    在应用了一些开发框架如spring的项目里如果要用到JMSQ虽然SPRING提供了部分对JMS的支持但l过我一D|间的应用发现QOO的封装在某些地方反而成为开发过E中的障。在实现诸如监听之类的代码段里人非常的懊恼Q即使用callback(回调)有些东西仍然不能够很好的被取到?

下面׃些TOMCAT上面JMS的支持既实现做一下整理?

1.很自然的你需要下载JMS实现,?opnerJMS或者activeMQ .下蝲地址www.jmsopen.com 或www.activeMQ.com

2.服务器下载以后的具体配置在以上两个网站上都有很详l的说明Q就不再列D了?

3.和WEB服务器的整合Q首先要配置应用的web.xmlq个文g配置如下Q?

1  <context-param>
