A. 如何用java封装解析一个多层次的XML文件，急求大神帮助

下面提供了XML解析成实知判体类，以及实体类转换成xml的方法。
public class SwitchXML {

private XStream xStream = new XStream();

private String xmlPath = "D:/data.xml";

// 1. obj -> xml(object类型转换为xml类型)
public String printXML(User user) {
System.out.println("obj -> xml");
String xml = xStream.toXML(user);
System.out.println(xml);
return xml;
}

// 2. xml->obj(xml类型转换为object类型，并打印)
public void printObj(String xml) {
System.out.println("xml -> obj");
User u = (User) xStream.fromXML(xml);
System.out.println(u.getUserName() + " " + u.getPassWord() + "搭隐改 " + u.getRegisteredTime());
}

// 3. 将object类型转换为xml类型，并写入XML文件(其他格式也可以，比如txt文件)
public void writerXML(User user) {
try {
FileOutputStream fs = new FileOutputStream(xmlPath);
xStream.toXML(user, fs);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}

// 4. 读取XML文件，加载进相应Object类型
public void readerXML() {
User user = new User();
FileInputStream fis = null;
try {
fis = new FileInputStream(xmlPath);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
xStream.fromXML(fis, user);
// 打印对象信息
System.out.println(user.toString());
// 打印对象的属性值
System.out.println(user.getUserName() + "-" + user.getPassWord() + "-"
+ user.getRegisteredTime());
}

public static void main(String[] args) {
// 用户名
String username = "admin";
/携衫/ 密码
String password = "admin";
// 注册时间
Date now = new Date();
SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");
String registeredtime = format.format(now);

User user = new User(username, password, registeredtime);
SwitchXML switchXML = new SwitchXML();

// 1. object类型转换为xml类型，在控制台打印
String xml = switchXML.printXML(user);
System.out.println("---------------------");
// 2. xml类型转换为object类型，在控制台打印
switchXML.printObj(xml);
System.out.println("---------------------");
// 3. 将object类型转换为xml类型，并写入XML文件
switchXML.writerXML(user);
System.out.println("---------------------");
// 4. 读取XML文件，加载进相应Object类型
switchXML.readerXML();

}

B. 用Java怎么把String类型的字符串转化为XML格式输出

java中将string转换成xml文件，使用开源jar包 dom4j：

packagecom.webdesk.swing.powertable.util;

importjava.io.ByteArrayInputStream;
importjava.io.File;
importjava.io.FileWriter;
importjava.io.IOException;

importorg.dom4j.Document;
importorg.dom4j.DocumentException;
importorg.dom4j.io.OutputFormat;
importorg.dom4j.io.SAXReader;
importorg.dom4j.io.XMLWriter;

publicclassXmlUtil{

(StringfileName){
try{
SAXReadersaxReader=newSAXReader();//新建一个解析类
DocumenttempDocument=saxReader.read(XmlUtil.class.getClassLoader().getResourceAsStream(fileName));//读入一个文件
returntempDocument.asXML();
}catch(DocumentExceptione){
e.printStackTrace();
}
returnnull;
}
//将字符串string类型转换成xml文件
publicstaticvoidstrChangeXML(Stringstr)throwsIOException{
SAXReadersaxReader=newSAXReader();
Documentdocument;
try{
document=saxReader.read(newByteArrayInputStream(str.getBytes("UTF-8")));
OutputFormatformat=OutputFormat.createPrettyPrint();
/**将document中的内容写入文件中*/
XMLWriterwriter=newXMLWriter(newFileWriter(newFile("src/com/webdesk/swing/powertable/digester/cctv.xml")),format);
writer.write(document);
writer.close();
}catch(DocumentExceptione){
e.printStackTrace();
}

}
}

C. xtream的工具使用

Xstream

需要的jar包

xpp3_min-1.1.4c.jar

xstream-1.3.1.jar

作用：

将xml字符串转换为java对象，或者将java对象转换为xml字符串

核心类：XStream xs = new XStream();

准备工作，先创建两个java类：City和Province

@XStreamAlias("city")

public class City {

private String name;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

}

@XStreamAlias("province")

public class Province {

@XStreamAsAttribute()

private String name;

@XStreamImplicit(itemFieldName = "city")

private List citys;

public List getCitys() {

return citys;

}

public void setCitys(List citys) {

this.citys = citys;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

}

第一：将java类转换为xml字符串

XStream xs = new XStream();

String xml = xs.toXML(JavaBean);

打印的字符串会将类的包名作为xml的标签，以及里面的字段都会变成标签。

例如将City类变为xml字符串：

武汉

将Province变成xml字符串

湖北

武汉

所以为了能将打印的字符串变为我们所想要的格式，可以使用Xstream提供的注解进行格式化输出

提供便捷注解

@XStreamAlias(别名) 对类和变量设置知慧别名

@XStreamAsAttribute 设置变量生成属性

@XStreamOmitField 设置变量不生成到XML

@XStreamImplicit(itemFieldName = “hobbies”) 设置集合类型变量别名

使注解生效

xStream.autodetectAnnotations(true);

第二：将xml字符串变为java对象

Object xs.fromXML(InputStream input); //将一个下买了指定的流变为java对象

Object xs.fromXML(String xml) /搭基答/将xml字符串变为java对象

Object xs.fromXML(InputStream input,Object root) ？

Object xs.fromXML(String xml,Object root) ？

注意：转换的xml文档必须与Java对象的格式对应

例如：将下面xml字符串转换为Java对象

武汉

则进行转换时候：

XStream xs = new XStream();

Object o = xs.fromXML(in);

若对应的java格式一定是：

包名为：com.domain

类名为：City

里面锋物有一个成员属性：name 提供setter/getter方法

若不是则可以使用别名：

a.为类设置别名

xs.alias("city", City.class);

b.为属性添加别名

xstream.useAttributeFor(Blog.class,"author")；

能不能通过注解将 xml转换为制定的java对象 ?

能，手动用方法添加别名

D. JAVA以POST方式提交XML获取返回值(返回格式为XML)

URL url = new URL(requestUrl);
HttpsURLConnection httpUrlConn = (HttpsURLConnection) url.openConnection();
httpUrlConn.setRequestMethod(“POST”);
OutputStream outputStream = httpUrlConn.getOutputStream();
outputStream.write(xml);
outputStream.close();
InputStream inputStream = httpUrlConn.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String str = null;
while ((str = bufferedReader.readLine()) != null) {
buffer.append(str);
}
bufferedReader.close();
inputStreamReader.close();
// 释放资源
inputStream.close();
inputStream = null;
httpUrlConn.disconnect();

E. java如何将一段xml的字符串文件写入到xml文件然后再解析出来

用dom4j，获亩中取指定的字节 List rootList = root.selectNodes("RETURN_CD"); rootList.get(0);
获旁让取的就是成迅启山功了哦

F. 如何把xml内容转换为java格式

使用XStream完成 java 类与 XML 互换。
下面代码实现了以下4种基本功能：
1. object类型转换为xml类型，在控制台打印
2. xml类型转换为object类型，在控制台打印
3. 将object类型转换为xml类型，并写入XML文件
4. 读取XML文件，加载进相应Object类型
====================================================
1。加载 XStream 需要的jar包 xstream-1.4.2.jar
xpp3_min-1.1.4c.jar
xmlpull-1.1.3.1.jar

2。创建实体类User.java
package com.entity;
/**
* 实体类
*/
public class User {
private String userName;
private String passWord;
private String registeredTime;
public User() { }
public User(String userName, String passWord, String registeredTime) {
this.userName = userName;
this.passWord = passWord;
this.registeredTime = registeredTime;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
public String getRegisteredTime() {
return registeredTime;
}
public void setRegisteredTime(String registeredTime) {
this.registeredTime = registeredTime;
}
}

3。编写功能实现类
package com.switcher;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.text.SimpleDateFormat;
import java.util.Date;
import com.entity.User;
import com.thoughtworks.xstream.XStream;
/**
*
* 使用 XStream不用任何映射就能实现多数 Java 对象的序列化。
* 在生成的 XML中对象名变成了元素名，类中的字符串组成了 XML中的元素内容。
* 使用 XStream 序列化的类不需要实现 Serializable 接口。
* XStream 是一种序列化工具而不是数据绑定工具
* 不能从XML 或者 XML Schema Definition (XSD) 文件生成类。
*/
public class SwitchXML {
/*
* XStream 不关心序列化/逆序列化的类的字段的可见性。
* 序列化/逆序列化类的字段不需要 getter 和 setter 方法。
* 序列化/逆序列化的类不需要有默认构造函数。
*/
private XStream xStream = new XStream();
private String xmlPath = "D:/userdata.xml";
// 1. obj -> xml(object类型转换为xml类型)
public String printXML(User user) {
System.out.println("obj -> xml");
String xml = xStream.toXML(user);
System.out.println(xml);
return xml;
}
// 2. xml->obj(xml类型转换为object类型，并打印)
public void printObj(String xml) {
System.out.println("xml -> obj");
User u = (User) xStream.fromXML(xml);
System.out.println(u.getUserName() + " " + u.getPassWord() + " " + u.getRegisteredTime());
}
// 3. 将object类型转换为xml类型，并写入XML文件(其他格式也可以，比如txt文件)
public void writerXML(User user) {
try {
FileOutputStream fs = new FileOutputStream(xmlPath);
xStream.toXML(user, fs);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
// 4. 读取XML文件，加载进相应Object类型
public void readerXML() {
User user = new User();
FileInputStream fis = null;
try {
fis = new FileInputStream(xmlPath);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
xStream.fromXML(fis, user);
// 打印对象信息
System.out.println(user.toString());
// 打印对象的属性值
System.out.println(user.getUserName() + "-" + user.getPassWord() + "-"
+ user.getRegisteredTime());
}
public static void main(String[] args) {
// 用户名
String username = "admin";
// 密码
String password = "admin";
// 注册时间
Date now = new Date();
SimpleDateFormat format = new SimpleDateFormat("yyyyMMddHHmmss");
String registeredtime = format.format(now);
User user = new User(username, password, registeredtime);
SwitchXML switchXML = new SwitchXML();
// 1. object类型转换为xml类型，在控制台打印
String xml = switchXML.printXML(user);
System.out.println("---------------------");
// 2. xml类型转换为object类型，在控制台打印
switchXML.printObj(xml);
System.out.println("---------------------");
// 3. 将object类型转换为xml类型，并写入XML文件
switchXML.writerXML(user);
System.out.println("---------------------");
// 4. 读取XML文件，加载进相应Object类型
switchXML.readerXML();
}
}

G. 求 Java序列化对象转xml方法....


/**这里应用了JAVA的Marshall方法
*对象转xml
*返回xml
*@paramtXLife
*@return
*/
publicstaticStringtXLiftToXML(com.TXLifetXLife){
	Stringxml="";
	try{
			ByteArrayOutputStreamout=newByteArrayOutputStream();
			JAXBContextjc=JAXBContext
					.newInstance("com");//包的命名空间
			Marshallerm=null;
			synchronized(jc){
				m=jc.createMarshaller();
			}
			m.setProperty(Marshaller.JAXB_ENCODING,"GBK");
			m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,Boolean.TRUE);

			m.marshal(tXLife,out);

			xml=out.toString();//赋值
		}catch(Exceptione){
			xml=null;
		}
	returnxml;
}

H. 求助java读取txt文件转化为xml形式输出

txt文件格式如下，采用的是一个服务端tomcat的log日志

J. 【高分求助】java 中数组格式的 json 怎么转成 xml

首先楼主的json数据有问题。

下面代码亲测，可用，两个文件放在同级目录：

Test.java

publicclassTest{

publicstaticvoidmain(String[]args){
	ConvertXMLtoJSON();
	StringjStr="{"users":{"user":["
		+"{"uid":"1","node_id":"2","children":[{"id":"43","value":"14"},{"id":"44","value":"15"}]},"
		+"{"uid":"2","node_id":"2","children":[{"id":"45","value":"11"},{"id":"46","value":"11"},{"id":"47","value":"16"}]},"
		+"{"uid":"3","node_id":"2","children":{"id":"48","value":"11"}}]}"
		+"}";
	System.out.println(jsontoXml(jStr));
}

publicstaticStringjsontoXml(Stringjson){
	try{
	XMLSerializerserializer=newXMLSerializer();
	JSONjsonObject=JSONSerializer.toJSON(json);
	returnserializer.write(jsonObject);
	}catch(Exceptione){
	e.printStackTrace();
	}
	returnnull;
}

(){
	InputStreamis=Test.class.getResourceAsStream("sample.xml");
	Stringxml;
	try{
	xml=IOUtils.toString(is);
	System.out.println(xml);
	XMLSerializerxmlSerializer=newXMLSerializer();
	JSONjson=xmlSerializer.read(xml);
	System.out.println(json.toString(1));
	}catch(IOExceptione){
	e.printStackTrace();
	}
}
}

sample.xml

<?xmlversion="1.0"encoding="utf-8"?>
