以前都是讀取properties檔案，現在過來分享一下讀取config檔案

1.新建WebSiteConfig.java

private String UserName="192.168.2.204:11211";
private String password ="":
//set get省略

2.新建中介軟體工具類CenterUtils.java

import java.beans.IntrospectionException;
import org.xml.sax.SAXException;
private static WebSiteConfig _WebSiteCfg;

// 網站配置
public static WebSiteConfig GetWebSiteConfig() {
try {
if (_WebSiteCfg == null) {
_WebSiteCfg = (WebSiteConfig) XMLUtil.xmlFile2Bean(
WebSiteConfig.class, Constanst.WEBROOTPATH + Constanst.WEBSITECONFIGPATH, "UTF-8");
}
} catch (IOException e) {
e.printStackTrace();
} catch (SAXException e) {
e.printStackTrace();
} catch (IntrospectionException e) {
e.printStackTrace();
}
return _WebSiteCfg;
}
 

3.新建常量類Constanst

//配置檔案地址  該路徑是WebRoot/XConfig/jdbc.config

public static final String WEBSITECONFIGPATH = "/XConfig/jdbc.config";

public static final String WEBROOTPATH = Constanst.class
.getProtectionDomain().getCodeSource().getLocation().getPath()
.indexOf("WEB-INF") > 0 ? Constanst.class
.getProtectionDomain()
.getCodeSource()
.getLocation()
.getPath()
.substring(
0,
Constanst.class.getProtectionDomain().getCodeSource()
.getLocation().getPath().indexOf("WEB-INF/classes"))
: Constanst.class.getProtectionDomain().getCodeSource()
.getLocation().getPath();
 

4.測試

System.out.println(CenterUtils.GetWebSiteConfig().getUsername());//root 這裡會根據jdbc.config配置節點的值，並不是類的192.168.2.204:11211";

System.out.println(CenterUtils.GetWebSiteConfig().getPassword())//1234

5配置檔案jdbc.config

<?xml version="1.0" encoding="UTF-8"?>
 <WebSiteConfig>
    <username>root</username>
    <password>1234</password>
  </WebSiteConfig>
 

6.這中間有個jar包 XMLUtil需要

所需jar
