Spring Xstream示例详解 _项目示例

Spring和Xstream集成
Spring和Xstream集成的示例

Xstream是一个库, 用于将对象序列化为xml, 反之亦然, 而无需任何映射文件。注意, castor需要一个映射文件。
XStreamMarshaller类提供了将对象封送为xml的工具, 反之亦然。
Spring和Xstream集成的示例(将Java对象编组为XML)
你需要创建以下文件, 以使用Spring和Xstream将Java对象编组为XML：

Employee.java
applicationContext.xml
Client.java

所需的Jar文件要运行此示例, 你需要加载：

Spring Core jar文件
Spring Web jar文件
xstream-1.3.jar

下载spring的所有jar文件, 包括core, web, aop, mvc, j2ee, remoting, oxm, jdbc, orm等。
下载xstream-1.3.jar
Employee.java
如果定义了三个属性id, setter和getter的名称和薪水。

package com.srcmini; 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
它定义了一个Bean xstreamMarshallerBean, 其中Employee类与OXM框架绑定在一起。

< ?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="http://www.srcmini.com/com.srcmini.Employee"> < /property> < /bean> < /beans>

Client.java
它从applicationContext.xml文件获取Marshaller的实例, 并调用marshal方法。

package com.srcmini; 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"); } }

示例输出
employee.xml
