XStream简单使用

?1、先到http://xstream.codehaus.org/architecture.html下载所需的xstream-1.x.jar

?2、新建一个java工程或者web工程

?3、把下载的jar包放在lib里

?4、新建一个类SourceBean.java

?package com.vane.tools.Xstream; public class SourceBean { private String username; private String password; private String connecturl; private String databasename; private String maxactive; private String maxidle; public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getConnecturl() { return connecturl; } public void setConnecturl(String connecturl) { this.connecturl = connecturl; } public String getDatabasename() { return databasename; } public void setDatabasename(String databasename) { this.databasename = databasename; } public String getMaxactive() { return maxactive; } public void setMaxactive(String maxactive) { this.maxactive = maxactive; } public String getMaxidle() { return maxidle; } public void setMaxidle(String maxidle) { this.maxidle = maxidle; } }

?5、新建一个source.xml

?<?xml version="1.0" encoding="gb2312" ?> <datasource> <username>sa</username> <password>sa</password> <connecturl>jdbc:jtds:sqlserver://localhost:1433/exam1</connecturl> <databasename>db</databasename> <maxactive>50</maxactive> <maxidle>20</maxidle> </datasource

6、开始写测试

?package com.vane.tools.Xstream; import java.io.BufferedReader; import java.io.FileNotFoundException; import java.io.FileReader; import com.thoughtworks.xstream.XStream; import com.thoughtworks.xstream.io.xml.DomDriver; public class Test { public static String getBeanToXML(SourceBean sb){ sb.setUsername("zx"); sb.setConnecturl("http://www.qq.com"); sb.setDatabasename("zx_db"); sb.setMaxactive("21"); sb.setMaxidle("5"); XStream xs=new XStream(); xs.alias("datasource",SourceBean.class); return xs.toXML(sb); } public static SourceBean getXMLtoString(String str){ SourceBean sb=new SourceBean(); try { XStream xs=new XStream(new DomDriver()); xs.alias("datasource",SourceBean.class); BufferedReader br=new BufferedReader(new FileReader(str)); sb=(SourceBean) xs.fromXML(br); } catch (FileNotFoundException e) { e.printStackTrace(); } return sb; } public static void main(String[] args) { //把 SourceBean类型的对象序列化为 XML //SourceBean sb=new SourceBean(); //System.out.println(getBeanToXML(sb)); //逆序列化 XML 并把数据装入 Java 对象 String str="c:/source.xml"; SourceBean sb=getXMLtoString(str); System.out.println(sb.getConnecturl()); } }
