因业务需求的增加，有多个数据源，数据源的ip 端口号、用户名、密码都一样，只是数据库名称不一样.
以下的数据源，能否精简合成一个数据源？ 然后再在其它类中引用.

dao.js 代码如下：

  daoTask : {
		    	type : "com.alibaba.druid.pool.DruidDataSource",
		        events : {
		            depose : 'close'
		        },
		        fields : {
		            driverClassName : 'com.microsoft.sqlserver.jdbc.SQLServerDriver',
		            url : 'jdbc:sqlserver://192.168.8.1:18991;DatabaseName=db_user_task',
		            username : 'juhe_test',
		            password : 'juhe_test'
	            }
		 },
		 
		  daoCoin : {
		    	type : "com.alibaba.druid.pool.DruidDataSource",
		        events : {
		            depose : 'close'
		        },
		        fields : {
		            driverClassName : 'com.microsoft.sqlserver.jdbc.SQLServerDriver',
		            url : 'jdbc:sqlserver://192.168.8.1:18991;DatabaseName=db_coin',
		            username : 'juhe_test',
		            password : 'juhe_test'
	            }
		 },

		 daoWorldMoney : {
		    	type : "com.alibaba.druid.pool.DruidDataSource",
		        events : {
		            depose : 'close'
		        },
		        fields : {
		            driverClassName : 'com.microsoft.sqlserver.jdbc.SQLServerDriver',
		            url : 'jdbc:sqlserver://192.168.8.1:18991;DatabaseName=db_money',
		            username : 'juhe_test',
		            password : 'juhe_test'
	            }
		 },

  
	    daotask : {
			type : "org.nutz.dao.impl.NutDao",
			args : [ { refer : "daoTask" } ]
	    },
	    
	    daocoin : {

	    },
	    daoworldmoney : {

			args : [ { refer : "daoWorldMoney" } ]
	    },
