异常积累：org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectio

启动时报错，原因如下：

url=jdbc:informix-sqli://192.168.2.114:8888/test:INFORMIXSERVER=testdb1;NEWLOCALE=en_us;NEWCODESET=zh_cn.gb;
中的字符集错误，应改为：
url=jdbc:informix-sqli://192.168.2.114:8888/test:INFORMIXSERVER=testdb1;NEWLOCALE=GB2312,en_us;NEWCODESET=GB2312,8859-1,819;
