JAVA配置文件取值方法

其实是很简单基础的东西，但对于初学者来说多掌握点东西总是好的，多的不说，直接上代码了，最简单粗暴的方式。

一、XML配置文件:

1.GlobalConfig.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<Settings xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<db_ip>192.168.10.229</db_ip>
<db_name>nest_test</db_name>
<user_name>root</user_name>
<password>root</password>
<url>http://192.168.0.1:8080/SMSServer/SMSServlet</url>
<templateId>213047611111</templateId>
</Settings>

2.XmlGlobal.java初始化
package xmlhelper;

public class XmlGlobal {

public static String Db_IP="";
public static String User_Name="";
public static String Pass_Word="";
public static boolean isConsolePro = false;
public static String Db_Name="";
public static String url="";
public static String templateId="";
}

3.GlobalXml.java读取文件赋值
package xmlhelper;

import java.io.FileInputStream;
import org.jdom.Document;
import org.jdom.Element;
import org.jdom.input.SAXBuilder;

public class GlobalXml {

public static void xmlParser(){
try {
String path="./resource/SysConfig/GlobalConfig.xml";
FileInputStream fi=new FileInputStream(path);
SAXBuilder builder = new SAXBuilder(false);
Document read_doc = builder.build(fi);
Element root = read_doc.getRootElement();
XmlGlobal.Db_IP=root.getChild("db_ip").getValue();
XmlGlobal.Db_Name=(root.getChild("db_name").getValue());
XmlGlobal.User_Name=root.getChild("user_name").getValue();
XmlGlobal.Pass_Word=root.getChild("password").getValue();
XmlGlobal.url=root.getChild("url").getValue();
XmlGlobal.templateId=root.getChild("templateId").getValue();

} catch (Exception e) {
e.printStackTrace();
}
}
}
调用:

String id = XmlGlobal.templateId;

二、properties文件：
1.configure.properties配置文件

SMS_url=https://www.baidu.com/20141029

AUTH_TOKEN=39cde072ec96

APP_ID=32fd03c4db6444

SERVER_IP=192.168.10.123:8080

2.ConfigureResource.java读取配置文件
package com.fisee.utils;

import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.InputStream;
import java.util.PropertyResourceBundle;
import java.util.ResourceBundle;

public class ConfigureResource {
private static ResourceBundle r;
private static InputStream in;

static
{
try
{
String path = System.getProperty("user.dir").replaceAll("\\\\", "/");
//System.out.println(path.replaceAll("bin", ""));
in = new BufferedInputStream(new FileInputStream(path.replaceAll("bin", "")+"webapps/SMSServer/resource/configure.properties"));
r = new PropertyResourceBundle(in);
}
catch (Exception e)
{
e.printStackTrace();
}
}

public static String getParam(String key)
{
try {
String s = new String(r.getString(key).getBytes("ISO-8859-1"),"GBK");
if(s.equalsIgnoreCase("SPACE")) s = " ";
return s;
} catch (Exception e) {
System.out.println(e);
return "Unknown";
}
}

public static void main(String[] args) {
System.out.println(ConfigureResource.getParam("SMS_url"));//取值
}
}
