Spring教程-Spring与XStream集成示例
Spring与XStream集成示例
XStream 是一个用于将对象序列化为XML格式,以及反之亦然,而无需任何映射文件的库。请注意,Castor 需要一个映射文件。
XStreamMarshaller 类提供了将对象编组为XML以及将XML反编组为对象的功能。
Spring与XStream集成示例(将Java对象编组为XML)
要使用Spring与XStream将Java对象编组为XML,您需要创建以下文件:
Employee.java
这个类定义了三个属性:id、name和salary,以及对应的setter和getter方法。
package cn.javatiku;
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
在这个文件中,我们定义了一个名为xstreamMarshallerBean的bean,将Employee类与OXM框架进行了绑定。
<?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="cn.javatiku.Employee"></property>
</bean>
</beans>
Client.java
这个类从applicationContext.xml文件中获取Marshaller的实例,并调用marshal方法。
package cn.javatiku;
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");
}
}
示例的输出
employee.xml
<cn.javatiku.Employee>
<id>101</id>
<name>Sonoo Jaiswal</name>
<salary>100000.0</salary>
</cn.javatiku.Employee>
