springMVC整合xStream

一. 简单介绍：

xStream能够轻易的将Java对象转换成xml、JSON。本篇博客将使用springMVC整合利用xStream转换xml。

关于xStream使用的博文：http://blog.csdn.net/zdp072/article/details/39054197

二. 实例：

1. 代码结构图：

2. 实体类：

（1）Account

public class Account {
    private int id;
    private String name;
    private String email;
    private String address;
    private Birthday birthday;

    // getter and setter

    @Override
    public String toString() {
        return this.name + "#" + this.id + "#" + this.address + "#" + this.birthday + "#" + this.email;
    }
}

（2）User

public class User {
	private String name;
	private int age;
	private Boolean sex;
	private String address;
	private Birthday birthday;
	
	// getter and setter
	
	@Override
    public String toString() {
        return this.name + "#" + this.age + "#" + this.sex + "#" + this.address + "#" + this.birthday.getBirthday();
    }
}

（3）Birthday

public class Birthday {
	private String birthday;

	public Birthday() {
	}
	
	// getter and setter
}

3. spring配置：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc 
		http://www.springframework.org/schema/mvc/spring-mvc.xsd
		http://www.springframework.org/schema/beans 
		http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context 
		http://www.springframework.org/schema/context/spring-context.xsd">

	<!-- 加入注解驱动 -->
	<mvc:annotation-driven />

	<!-- 默认扫描的包路径 -->
	<context:component-scan base-package="com.zdp" />

	<!-- 视图解析器 -->
	<bean class="org.springframework.web.servlet.view.BeanNameViewResolver">
		<property name="order" value="1" />
	</bean>

	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
	</bean>

	<!-- xml视图，XStreamMarshaller，能够转换不论什么形式的java对象 -->
	<bean name="xStreamMarshallingView" class="org.springframework.web.servlet.view.xml.MarshallingView">
		<property name="marshaller">
			<bean class="org.springframework.oxm.xstream.XStreamMarshaller">
				<!-- 启用annotation -->
				<property name="autodetectAnnotations" value="true" />
				
				<!-- 类名别名 -->
				<property name="aliases">
					<map>
						<!-- Account这个类的别名就变成了myBeans，那么转换后的xml中就是myBeans -->
						<entry key="myBeans" value="com.zdp.domain.Account" />
					</map>
				</property>
				
				<!-- 基本属性别名 -->
				<property name="fieldAliases">
					<map>
						<!-- Account中的brithday这个属性 -->
						<entry key="com.zdp.domain.Account.birthday" value="birthday" />
					</map>
				</property>
			</bean>
		</property>
	</bean>
</beans>

4. XstreamController

/**
 * 利用xStream进行Java对象到XML的转换技术
 */
@Controller
@RequestMapping("/xstream/view")
public class XStreamController {

	// 普通JavaBean转换成XML
	// url: http://localhost:8080/springmvc_xStream/xstream/view/doXMLXstream
	@RequestMapping("/doXMLXstream")
	public ModelAndView doXMLJaxb2View() {
		ModelAndView mav = new ModelAndView("xStreamMarshallingView");
		Account account = new Account();
		account.setAddress("address");
		account.setEmail("email");
		account.setId(1);
		account.setName("haha");
		Birthday day = new Birthday();
		day.setBirthday("2010-11-22");
		account.setBirthday(day);
		mav.addObject(BindingResult.MODEL_KEY_PREFIX, account);
		return mav;
	}

	// 转换带List属性的JavaBean
	// url: http://localhost:8080/springmvc_xStream/xstream/view/doListXMLXstream
	@RequestMapping("/doListXMLXstream")
	public ModelAndView doListXMLXStreamView() {
		ModelAndView mav = new ModelAndView("xStreamMarshallingView");
		List<Object> list = new ArrayList<Object>(); 
		for (int i = 0; i < 3; i++) {
			Account account = new Account();
			account.setAddress("北京#" + i);
			account.setEmail("email" + i + "@12" + i + ".com");
			account.setId(1 + i);
			account.setName("haha#" + i);
			Birthday birthday = new Birthday();
			birthday.setBirthday("2010-11-2" + i);
			account.setBirthday(birthday);
			list.add(account);

			User user = new User();
			user.setAddress("china GuangZhou 广州# " + i);
			user.setAge(23 + i);
			user.setBirthday(birthday);
			user.setName("jack#" + i);
			user.setSex(Boolean.parseBoolean(i + ""));
			list.add(user);
		}

		mav.addObject(list);
		return mav;
	}

	// 转换带有Map属性的JavaBean
	// url: http://localhost:8080/springmvc_xStream/xstream/view/doMapXMLXstream
	@RequestMapping("/doMapXMLXstream")
	public ModelAndView doDifferXMLXStreamView() {
		ModelAndView mav = new ModelAndView("xStreamMarshallingView");
		Account account = new Account();
		account.setAddress("广东");
		account.setEmail("email");
		account.setId(1);
		account.setName("haha");
		Birthday birthday = new Birthday();
		birthday.setBirthday("2010-11-22");
		account.setBirthday(birthday);

		User user = new User();
		user.setAddress("china GuangZhou");
		user.setAge(23);
		user.setBirthday(birthday);
		user.setName("jack");
		user.setSex(true);

		Map<String, Object> map = new HashMap<String, Object>();
		map.put("account", account);
		map.put("user", user);
		mav.addObject(map);
		return mav;
	}

	// 转换数组
	// url: http://localhost:8080/springmvc_xStream/xstream/view/doArrayXMLXstream
	@RequestMapping("/doArrayXMLXstream")
	public ModelAndView doArrayXMLXStreamView() {
		ModelAndView mav = new ModelAndView("xStreamMarshallingView");
		Account[] accountArr = new Account[2]; 
		
		Account account = new Account();
		account.setAddress("北京");
		account.setEmail("email");
		account.setId(1);
		account.setName("haha");
		Birthday birthday = new Birthday();
		birthday.setBirthday("2010-11-22");
		account.setBirthday(birthday);
		accountArr[0] = account;
		
		account = new Account();
		account.setAddress("上海");
		account.setEmail("email");
		account.setId(1);
		account.setName("haha");
		birthday = new Birthday();
		birthday.setBirthday("2014-11-22");
		account.setBirthday(birthday);
		accountArr[1] = account;
		
		mav.addObject(accountArr);
		return mav;
	}
}
