XStream 初探,很给力

主要代码 /** * Xstream 测试 * @return */ @RequestMapping("/forward/xstream") public String xstream(){ String str = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><epay><items><item><id>2</id><name>cyc1</name></item><item><id>1</id><name>cyc</name></item></items></epay>"; XStream xstream = new XStream(); //获取生成的对象 TestVo testVo = getPerson(); //构建对应的节点(这里很重要构建生成的Xml 文件或者对象的节点) xstream.alias("epay",TestVo.class); xstream.aliasField("items",TestVo.class, "list"); xstream.alias("item", tests.class); //将对象转为xml String xml = xstream.toXML(testVo); System.out.println("cyc==== XStream:"+xml); //将xml转为对象 TestVo testVos = (TestVo) xstream.fromXML(str); System.out.println("cyc==== testVos"+testVos); //将对象再次转为xml String xml2 = xstream.toXML(testVos); System.out.println("cyc==== XStream2:"+xml2); System.out.println("cyc==== Size:"+testVos.getList().size()); return "publicTpl/notChrome"; } public TestVo getPerson(){ TestVo testVo = new TestVo(); List<tests> list = new ArrayList<tests>(); for(int i=0;i<10;i++){ tests tests = new tests(); tests.setId("1"); tests.setName("cyc"); list.add(tests); } testVo.setList(list); return testVo; } TestVo类代码: public class TestVo { private List<tests> list;

public List<tests> getList() {
	return list;
}

public void setList(List<tests> list) {
	this.list = list;
}

@Override
public String toString() {
	return "TestVo [list=" + list + "]";
}

}

tests类代码:
public class tests {
	private String id;
	private String name;
	public String getId() {
		return id;
	}
	public void setId(String id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	@Override
	public String toString() {
		return "tests [id=" + id + ", name=" + name + "]";
	}
	
}

输出结果：

    <item>
      <id>1</id>

注意事项:若是想在java 项目中运行这个须要添加一些关联的包否则的话会报一个：
