高分求 JDBC多事务的实例

Question

private static int TRANSACTION_READ_UNCOMMITTED=1;
private Properties dbs_properties=new Properties();
private String strConnection="jdbc:microsoft:sqlserver://192.168.0.169:1433";
//函数getConnectIni获取据库连接的参数
     private void getConnectIni()
     {
         dbs_properties.put("User","sa");
         dbs_properties.put("Password","741028");
         dbs_properties.put("DatabaseName","WebGps");
         dbs_properties.put("SelectMethod","cursor"); //设置游标形式，以便于设置事务
     }//实现SqlServer数据库的连接
     private Connection dbsConnection()
     {
         Connection dbsCon=null;
         try
         {
             dbsCon=DriverManager.getConnection(strConnection,dbs_properties);
             dbsCon.setAutoCommit(false);//设置事务为手动模式
             dbsCon.setTransactionIsolation(TRANSACTION_READ_UNCOMMITTED); //设置数据库事务隔离级别为最高级别
         }
         catch(Exception ex)
         {
             writeErrorLog(ex.getMessage().toString());
         }
         return dbsCon;
     }
