CapabilityForConnection?主運行程序，讀取配置文件init.properties、reference.properties初始化參數。調用POOLTEST（一次完整的測試用例），計算其平均時間與使用連接數

簡單的不能再簡單的測試代碼：
package?com.cea.repository.test.testdata;
import?com.cea.repository.connection.drive.ConnectionFactory;
import?java.sql.Connection;
import?java.sql.Statement;
import?java.sql.ResultSet;
import?java.sql.PreparedStatement;
import?java.util.HashMap;
import?java.util.Map;
import?java.util.List;
import?java.util.ArrayList;
import?com.cea.repository.test.PoolTest;
import?com.cea.repository.connection.poolpository.PoolFactory;
/**

?*?

?*?@author?小舟
?*?@version?1.0
?*/
public?class?MainExecute?{
????public?static?void?main(String[]?args)?throws?Exception?{
???????testConnection();
????}
????static?void?testConnection()?throws?Exception?{
????????for?(int?i?=?0;?i?<?PoolTest.CONNECTIONS;?i++)?{
????????????Connection?con?=?PoolFactory.newInstance();
????????????//這里的改變直接影響連接的復用
????????????Thread.sleep(50);
????????????PoolTest.poolTestMap.put(con.toString(),?"");
????????????con.close();
????????}
????}
}
三個配置文件的內容：
init.properties文件
#運行的次數
init=5
#并發執行MainExecute的數量所匹配的名字
name0=execsum
#一次MainExecute執行所請求的連接數所匹配的名字
name1=opencon
reference.properties文件
#過濾數據
execsum0=10
opencon0=1
#第一次測試數據
execsum1=100
opencon1=6
#第二次測試數據
execsum2=85
opencon2=9
#第三次測試數據
execsum3=140
opencon3=3
最后一個是pool-config.xml數據源配置：
xml?version="1.0"?encoding="GB2312"?>
