虽然hibernate自带�?ji��n)连接池�Q�也支持一些其他的�q�接池，但是查看各方面的资料�Q�觉得还是proxool�q�接池占��L��Q�现在对配置的方法做些记录，以备后用�Q?

1. hibernate.cfg.xml

          org.hibernate.connection.ProxoolConnectionProvider

     MYPool
     proxool.xml
     true
     org.hibernate.dialect.SQLServerDialect

2 . proxool.xml

MYPool

摘自springside论坛

一�?br />

�l�过N多试验，�l�于自己把这个问题搞定了(ji��n)�?br />
�|�上关于C3P0在spring中的配置�Q�几乎没有完全正��的�Q�至��我�q�没发现�Q�。查�?ji��n)c3p0的文档，又试验过N�ơ。得出如下配�|�是正确的：(x��)

      ${jdbc.driverClassName}
      ${jdbc.url}
      ${jdbc.username}
      ${jdbc.password}

      1
      20
      1800
      2
      0
      2
      1800
      30
      true
      false






classpath:/com/licaionline/domain/




org.hibernate.dialect.MySQLDialect
   true
true
            auto
            true
            true






注意�Q�注释掉的那些，都是错误的。网上流行的�Q�基本上跟注释掉的那些差不多。配错了(ji��n)�Q��ƈ无异常，�q�是能正�怋�用。但是所作的配置不�v作用�?br />

二�?br />

起作用的�Q�是datasource里面的这一句：(x��)
1800

�q�儿讄��成每�?800�U�就扫描一�ơ，��(g��)查一下空闲的链接。所以，用户基本上不�?x��)得到空闲的链接了(ji��n)�?br />
如果再不攑ֿ�(j��)�Q?br />false
�q�儿讄��成true。每�ơ连接之前，都要��一下。但是这样会(x��)影响效率�?br />

三�?br />
解决的方法有3�U�：(x��)

增加wait_timeout的时间�?
减少Connection pools中connection的lifetime�?
��试Connection pools中connection的有效性�?
当然最好的办法是同时综合��用上�q?�U�方法，下面��DBCP和C3P0分别做一说明�Q�假设wait_timeout为默认的8��时

DBCP增加以下配置信息:

//set to 'SELECT 1'
validati
//set to 'true'
testWhileIdle = "true"
//some positive integer
timeBetweenEvictionRunsMillis = 3600000
//set to something smaller than 'wait_timeout'
minEvictableIdleTimeMillis = 18000000
//if you don't mind a hit for every getConnection(), set to "true"
test

C3P0增加以下配置信息:

//set to 'SELECT 1'
preferredTestQuery = 'SELECT 1'
//set to something much less than wait_timeout, prevents connections from going stale
idleConnectionTestPeriod = 18000
//set to something slightly less than wait_timeout, preventing 'stale' connections from being handed out
maxIdleTime = 25000
//if you can take the performance 'hit', set to "true"
testConnectionOnCheckout = true

更多的配�|�信息大家可以查看C3P0文档�Q�Connector/J文档�Q�以�?qi��ng)DBCP的文档�?br />

Birt GDI ERROR

Thu, 21 Dec 2006 03:59:00 GMT

There are two solutions:
- install GDI+
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdicpp/gdiplus/gdiplus.asp
or
-start Eclipse with "eclipse.exe -vmargs -DR31ENHANCE=false". This will not
use any of the new SWT 3.1 functionalities, and so doesnt' require GDI+.

用Hibernate操作Oracle Clob字段

Thu, 11 May 2006 10:40:00 GMT

1.在HBM里对应CLOB型的字段为：(x��)java.sql.Clob,用MyEclipse DataExplorer生成后手动改一下即可，当然POJO也一样啊�Q�如�Q?br />

HBM:
<hibernate-mapping>
<class name="com.chinacars.filterdata.beans.TblWapNews2" table="TBL_WAP_NEWS2">
        <id name="id" type="java.lang.Long">
            <column name="ID" precision="22" scale="0" />
        id>
       <property name="content" type="java.sql.Clob">
            <column name="CONTENT" />
        property>

class>
hibernate-mapping>

POJO:
import java.sql.Clob;
public class test {
private Clob content;

}

2.首先要给C(j��)lob里写一个�?如：(x��)注意看一下有底色的地方就明白�?ji��n)�?br />

package com.chinacars.filterdata.modidata;

    private static final Log logger = LogFactory.getLog(ModiData2.class);

    public static void main(String[] args) {

        WapNews1DAO wapNews1DAO = new WapNews1DAO();
        WapNews2DAO wapNews2DAO = new WapNews2DAO();

        TblWapNews1 news1 = new TblWapNews1();
        TblWapNews2 news2 = new TblWapNews2();

        List list = wapNews1DAO.getWapNews();
        Clob contentClob = null;
        String cStr = "1";
        String title;

        for (int i = 0; i < list.size(); i++) {
            logger.info("============The number : " + i);
            news1 = (TblWapNews1) list.get(i);
            contentClob = news1.getContent();
            try {
                PropertyUtils.copyProperties(news2, news1);
            } catch (IllegalAccessException e) {
                logger.error(e);
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                logger.error(e);
                e.printStackTrace();
            } catch (NoSuchMethodException e) {
                logger.error(e);
                e.printStackTrace();
            }
            title = news1.getTitle();
            if(title != null) {
                title = title.replaceAll("�Q?/span>", "");
                news2.setTitle(title);
            }
            news2.setContent(Hibernate.createClob(cStr));
            try {
                wapNews2DAO.saveWapNews(news2, StringProcess
                        .delInvalidChar(contentClob.getSubString(1,
                                (int) contentClob.length())));

            } catch (SQLException e) {
                logger.error(e);
                e.printStackTrace();
            }
        }

    }

}
