用proxool连接池方式，只有datasource发生变化，其他的无变动



  需要加入proxool.jar

     < bean  id ="dataSource"  class ="org.logicalcobwebs.proxool.ProxoolDataSource"  destroy-method ="close" >
         < property  name ="alias"  value ="test" ></ property >
         < property  name ="delegateProperties" >
             < value > user=${jdbc.username},password=${jdbc.password} </ value >
         </ property >
         < property  name ="user"  value ="${jdbc.username}" />
         < property  name ="password"  value ="${jdbc.password}" />
         < property  name ="driver"  value ="${jdbc.driverClassName}" />
         < property  name ="driverUrl"  value ="${jdbc.url}" />
         < property  name ="houseKeepingTestSql"  value ="select CURRENT_DATE" ></ property >
        <!-- 此处继续增加proxool属性，详细见proxool文档-->
     </ bean >

此处说明一下：属性中的user和password不起任何作用，需要用delegateProperties方式写一下，否则会报错误，如下
    org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user ''. The user is not associated with a trusted SQL Server connection.
但是user和password还不能被去掉。

除了上面的用delegateProperties之外，还可以将用户名和密码直接写在url后面。

proxool属性的说明，在这里写的比较详细
