如何读取配置文件连接数据库

db.property

db.driver=oracle.jdbc.driver.OracleDriver
db.url=jdbc:oracle:thin:@127.0.0.1:1521:test
db.user=user
db.password=password

biz.invoke=direct

// 测试

public class test{
String property = "db";

public Connection connect() throws Exception {
ResourceBundle rb = ResourceBundle.getBundle(property);
Class.forName(rb.getString("db.driver"));
Connection con = DriverManager.getConnection(
rb.getString("db.url"),
rb.getString("db.user"),
rb.getString("db.password"));
con.setAutoCommit(false);
return con;
}
}
