Xstream 是一個(gè)庫(kù)，用于將對(duì)象序列化為xml，反之亦然，而無(wú)需任何映射文件。注意，castor需要一個(gè)映射文件。
XStreamMarshaller 類提供了將對(duì)象編組為xml的功能，反之亦然。
您需要為創(chuàng)建以下文件通過(guò)Xstream使用Spring將Java對(duì)象編組為XML:
Employee.java applicationContext.xml Client.java
要運(yùn)行此示例，您需要加載:
Spring Core jar文件 Spring Web jar文件 xstream-1.3.jar
下載spring的所有jar文件，包括core，web，aop，mvc，j2ee，remoting ，oxm，jdbc，orm等。
下載xstream-1.3.jar
Employee.java
如果定義了三個(gè)屬性id，setter和getters的名稱和薪金。
package com.nhooo;
public class Employee {
private int id;
private String name;
private float salary;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public float getSalary() {
return salary;
}
public void setSalary(float salary) {
this.salary = salary;
}
}
applicationContext.xml
它定義了一個(gè)Bean xstreamMarshallerBean，其中Employee類與OXM框架綁定。
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <bean id="xstreamMarshallerBean" class="org.springframework.oxm.xstream.XStreamMarshaller"> <property name="annotatedClasses" value="com.nhooo.Employee"></property> </bean> </beans>
Client.java
它從applicationContext.xml文件獲取Marshaller的實(shí)例并調(diào)用marshal方法。
package com.nhooo;
import java.io.FileWriter;
import java.io.IOException;
import javax.xml.transform.stream.StreamResult;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.oxm.Marshaller;
public class Client{
public static void main(String[] args)throws IOException{
ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
Marshaller marshaller = (Marshaller)context.getBean("xstreamMarshallerBean");
Employee employee=new Employee();
employee.setId(101);
employee.setName("Sonoo Jaiswal");
employee.setSalary(100000);
marshaller.marshal(employee, new StreamResult(new FileWriter("employee.xml")));
System.out.println("XML Created Sucessfully");
}
}
employee.xml
<com.nhooo.Employee> <id>101</id> <name>Sonoo Jaiswal</name> <salary>100000.0</salary> </com.nhooo.Employee>
