数据源配置的URL如下：
jdbc:oracle:thin:@(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.8.3)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 10.1.8.4)(PORT = 1521))(LOAD_BALANCE = on))(CONNECT_DATA = (SERVICE_NAME = lisdb)(failover_mode=(type=select)(method=basice))))
讲Host替换成自己的数据库的真实IP地址、PORT替换成自己的数据库的端口号、SERVICE_NAME替换，其他保持不变。
