[Java] JSP 存取config.properties

今天有一個config.properties在專案中，內容如下:

db_user = postgres
db_password = dbpw
db_location=192.168.1.100
db_name=Test

這樣做的好處是避免IP或密碼變更時，無須動到CODE

<%@page import="java.util.ResourceBundle"%>
<% ResourceBundle resource = ResourceBundle.getBundle("config");
String DB_Name = resource.getString("db_name");
String IP = resource.getString("db_location");
String USER = resource.getString("db_user");
String PSW = resource.getString("db_password");
%>
