（绝对有效）sqlserver2000链接proxool连接池，终于配置出spring整合struts，hibernate annotation(pool数据池,sqlserver2000数据库)
首先proxool.xml(需要proxool-0.9.1.jar，proxool-cglib.jar和三个sqlserver包)
<?xml version="1.0" encoding="UTF-8"?>
<something-else-entirely>
<proxool>
<alias>pool</alias>
<driver-url>jdbc:microsoft:sqlserver://localhost:1433;databaseName=tour</driver-url>
<driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>
<driver-properties>
<property name="user" value="sa"/>
<property name="password" value="sa"/>
</driver-properties>
<house-keeping-sleep-time>90000</house-keeping-sleep-time>
<maximum-new-connections>20</maximum-new-connections>

然后web.xml

由于第1次配置,所以有错请指出...
还有1种，在网络上找到的说法，本人没试过
- proxool：关于这个连接池，网上说的例子也有很多，说是性能最好的一个连接池，坑爹的是，网上讲的它跟spring的整合，有很多都是不对的，直接通过spring配置就可以了，没有必要像网上说的，把listener，改成servlet，直接通过spring的bean配置就可以了，这个在网也有很多。关于这个连接池，我在测试时，发现默认情况下，是不会自动重连的，需要通过如下配置： <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="org.logicalcobwebs.proxool.ProxoolDriver" />
<property name="url" value="xxxx.xml" />
</bean> 在xxxx.xml里配置 <proxool>
<alias>pool</alias>
<driver-url>jdbc:mysql://192.168.1.4:3306/MIGRATE_TEST?characterEncoding=utf- 8&autoReconnect=true</driver-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<driver-properties>
<property name="user" value="website" />
<property name="password" value="website" />
<property name="autoReconnect" value="true" />
</driver-properties>
<minimum-connection-count>1</minimum-connection-count>
<maximum-connection-count>8</maximum-connection-count>
<prototype-count>1</prototype-count>
<test-before-use>true</test-before-use>
<house-keeping-sleep-time>60000</house-keeping-sleep-time>
</proxool> mysql的URL的后面要加上autoReconnect=true，值得注意的是，当使用ibatis时，日志会报warn:registered a statement as closed which wasn't known to be open. 那是因为在ibatis
public class SqlMapClientTemplate extends JdbcAccessor implements SqlMapClientOperations {
public <T> T execute(SqlMapClientCallback<T> action) throws DataAccessException {
..........
finally {
// Only close SqlMapSession if we know we've actually opened it
// at the present level.
if (ibatisCon == null) {
session.close();// 由这段引起的，池ibatisCon不为空时，session永远不会关闭
}
}
}
}
将红色部分改为 if (ibatisCon != null)，就行了
好了,废话不多说了,需要更详细的资料,可以下载源代码,可以到http://download.csdn.net/detail/qq435967718/4738630下载
数据库到http://download.csdn.net/detail/qq435967718/4757430下载（我也不想分开放，不过上次忘记发了，所以补充上去的，1分，也不贵）
.网站经过tomcat发布后，可以访问这个地址（http://localhost:8080/项目名/index1）或（http://localhost:8080/Tour_Struts9//index1）,忘记了，自己2个都试试吧，然后导航点击“用户管理”，再点击“网络管理员”，他就把数据库里的数据拿出来了。
