GBase 8t数据库的JDBC连接字符串是什么？

jdbc:informix-sqli://:<端口号>/<默认连接的库名>:informixserver=
例如：jdbc:informix-sqli://127.0.0.1:9099/test:informixserver=ol_informix1210

JAVA连接access数据库一个完整的例子，希望对你有帮助 import java.sql.*;class Employee
{
public static void main(String args[])
{
Statement st;
Connection con;
try{
System.out.println("正在连接数据库...");
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc:odbc:mydsn");
System.out.println("已连接到数据库");
Statement stmt=con.createStatement();
String query="select * from Employees"; ResultSet rs=stmt.executeQuery("select * from Employees");
while(rs.next())
{
String name=rs.getString("Address");
System.out.println(name);
} stmt.close();
con.close();
}
catch (Exception em)
{
System.out.println("出现的异常为:"+em);
}
}
}
