xstream 小结 一个标签下有多个同名标签

Answer 1

有多个同名标签时怎么解析

方式一用加注解的方式

xml文件中，有多个元素response,a,b,c,d,name

5个name 中国，美国，俄罗斯，英国，法国

1)bean.java

2)在list上加注解

@XStreamImplicit(itemFieldName="searchContent")// @XStreamImplicit加注解,itemFieldName说明隐含的元素名

3)在test.java中，在根节点转换之前调用

stream.autodetectAnnotations(true);

package bean;

public class Testresponse {

private User user;

public User getUser() {
return user;
}

public void setUser(User user) {
this.user = user;
}
}

package bean;

import java.util.List;

import com.thoughtworks.xstream.annotations.XStreamImplicit;

public class User {
@XStreamImplicit(itemFieldName="name")//标注加在list上
private List<String> name;

public List<String> getName() {
return name;
}

public void setName(List<String> name) {
this.name = name;
}

}

package bean;

import java.io.File;
import java.io.FileReader;
import java.io.Reader;
import java.util.HashMap;
import java.util.Set;
import com.thoughtworks.xstream.XStream;

public class Test {
@SuppressWarnings("unchecked")
public static void main(String args[]) {
Reader reader = null;
File file = new File(
"C://Users//ThinkPad//workspace8//xstreamtest//WebRoot//a.xml");
try {
reader = new FileReader(file);

XStream xstream = new XStream();

HashMap<String, Class> hashmap = new HashMap<String, Class>();
hashmap.put("user", User.class);
hashmap.put("reponse", Testresponse.class);

Set<String> keyset = hashmap.keySet();
for (String str : keyset) {
xstream.alias(str, hashmap.get(str));
}

xstream.autodetectAnnotations(true);
Testresponse response = (Testresponse) xstream.fromXML(reader);
System.out.println(response);
String s = xstream.toXML(response);
System.out.println(s);

} catch (Exception e) {
e.printStackTrace();
}

}
}

<?xml version="1.0" encoding="UTF-8"?>
<reponse>
<user>
<name>jack1</name>
<name>jack2</name>
<name>jack3</name>
</user>
</reponse>
