A. 如何用java封裝解析一個多層次的XML文件，急求大神幫助

下面提供了XML解析成實知判體類，以及實體類轉換成xml的方法。
public class SwitchXML {

private XStream xStream = new XStream();

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

// 1. obj -> xml(object類型轉換為xml類型)
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類型轉換為object類型，並列印)
public void printObj(String xml) {
System.out.println("xml -> obj");
User u = (User) xStream.fromXML(xml);
System.out.println(u.getUserName() + " " + u.getPassWord() + "搭隱改 " + u.getRegisteredTime());
}

// 3. 將object類型轉換為xml類型，並寫入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. 讀取XML文件，載入進相應Object類型
public void readerXML() {
User user = new User();
FileInputStream fis = null;
try {
fis = new FileInputStream(xmlPath);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
xStream.fromXML(fis, user);
// 列印對象信息
System.out.println(user.toString());
// 列印對象的屬性值
System.out.println(user.getUserName() + "-" + user.getPassWord() + "-"
+ user.getRegisteredTime());
}

public static void main(String[] args) {
// 用戶名
String username = "admin";
/攜衫/ 密碼
String password = "admin";
// 注冊時間
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類型轉換為xml類型，在控制台列印
String xml = switchXML.printXML(user);
System.out.println("---------------------");
// 2. xml類型轉換為object類型，在控制台列印
switchXML.printObj(xml);
System.out.println("---------------------");
// 3. 將object類型轉換為xml類型，並寫入XML文件
switchXML.writerXML(user);
System.out.println("---------------------");
// 4. 讀取XML文件，載入進相應Object類型
switchXML.readerXML();

}

B. 用Java怎麼把String類型的字元串轉化為XML格式輸出

java中將string轉換成xml文件，使用開源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();//新建一個解析類
DocumenttempDocument=saxReader.read(XmlUtil.class.getClassLoader().getResourceAsStream(fileName));//讀入一個文件
returntempDocument.asXML();
}catch(DocumentExceptione){
e.printStackTrace();
}
returnnull;
}
//將字元串string類型轉換成xml文件
publicstaticvoidstrChangeXML(Stringstr)throwsIOException{
SAXReadersaxReader=newSAXReader();
Documentdocument;
try{
document=saxReader.read(newByteArrayInputStream(str.getBytes("UTF-8")));
OutputFormatformat=OutputFormat.createPrettyPrint();
/**將document中的內容寫入文件中*/
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：

將xml字元串轉換為java對象，或者將java對象轉換為xml字元串

核心類：XStream xs = new XStream();

准備工作，先創建兩個java類：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：將java類轉換為xml字元串

XStream xs = new XStream();

String xml = xs.toXML(JavaBean);

列印的字元串會將類的包名作為xml的標簽，以及裡面的欄位都會變成標簽。

例如將City類變為xml字元串：

武漢

將Province變成xml字元串

湖北

武漢

所以為了能將列印的字元串變為我們所想要的格式，可以使用Xstream提供的註解進行格式化輸出

提供便捷註解

@XStreamAlias(別名) 對類和變數設置知慧別名

@XStreamAsAttribute 設置變數生成屬性

@XStreamOmitField 設置變數不生成到XML

@XStreamImplicit(itemFieldName = 「hobbies」) 設置集合類型變數別名

使註解生效

xStream.autodetectAnnotations(true);

第二：將xml字元串變為java對象

Object xs.fromXML(InputStream input); //將一個下買了指定的流變為java對象

Object xs.fromXML(String xml) /搭基答/將xml字元串變為java對象

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

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

注意：轉換的xml文檔必須與Java對象的格式對應

例如：將下面xml字元串轉換為Java對象

武漢

則進行轉換時候：

XStream xs = new XStream();

Object o = xs.fromXML(in);

若對應的java格式一定是：

包名為：com.domain

類名為：City

裡面鋒物有一個成員屬性：name 提供setter/getter方法

若不是則可以使用別名：

a.為類設置別名

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

b.為屬性添加別名

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

能不能通過註解將 xml轉換為制定的java對象 ?

能，手動用方法添加別名

D. JAVA以POST方式提交XML獲取返回值(返回格式為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();
// 釋放資源
inputStream.close();
inputStream = null;
httpUrlConn.disconnect();

E. java如何將一段xml的字元串文件寫入到xml文件然後再解析出來

用dom4j，獲畝中取指定的位元組 List rootList = root.selectNodes("RETURN_CD"); rootList.get(0);
獲旁讓取的就是成迅啟山功了哦

F. 如何把xml內容轉換為java格式

使用XStream完成 java 類與 XML 互換。
下面代碼實現了以下4種基本功能：
1. object類型轉換為xml類型，在控制台列印
2. xml類型轉換為object類型，在控制台列印
3. 將object類型轉換為xml類型，並寫入XML文件
4. 讀取XML文件，載入進相應Object類型
====================================================
1。載入 XStream 需要的jar包 xstream-1.4.2.jar
xpp3_min-1.1.4c.jar
xmlpull-1.1.3.1.jar

2。創建實體類User.java
package com.entity;
/**
* 實體類
*/
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。編寫功能實現類
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不用任何映射就能實現多數 Java 對象的序列化。
* 在生成的 XML中對象名變成了元素名，類中的字元串組成了 XML中的元素內容。
* 使用 XStream 序列化的類不需要實現 Serializable 介面。
* XStream 是一種序列化工具而不是數據綁定工具
* 不能從XML 或者 XML Schema Definition (XSD) 文件生成類。
*/
public class SwitchXML {
/*
* XStream 不關心序列化/逆序列化的類的欄位的可見性。
* 序列化/逆序列化類的欄位不需要 getter 和 setter 方法。
* 序列化/逆序列化的類不需要有默認構造函數。
*/
private XStream xStream = new XStream();
private String xmlPath = "D:/userdata.xml";
// 1. obj -> xml(object類型轉換為xml類型)
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類型轉換為object類型，並列印)
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. 將object類型轉換為xml類型，並寫入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. 讀取XML文件，載入進相應Object類型
public void readerXML() {
User user = new User();
FileInputStream fis = null;
try {
fis = new FileInputStream(xmlPath);
} catch (FileNotFoundException e) {
e.printStackTrace();
}
xStream.fromXML(fis, user);
// 列印對象信息
System.out.println(user.toString());
// 列印對象的屬性值
System.out.println(user.getUserName() + "-" + user.getPassWord() + "-"
+ user.getRegisteredTime());
}
public static void main(String[] args) {
// 用戶名
String username = "admin";
// 密碼
String password = "admin";
// 注冊時間
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類型轉換為xml類型，在控制台列印
String xml = switchXML.printXML(user);
System.out.println("---------------------");
// 2. xml類型轉換為object類型，在控制台列印
switchXML.printObj(xml);
System.out.println("---------------------");
// 3. 將object類型轉換為xml類型，並寫入XML文件
switchXML.writerXML(user);
System.out.println("---------------------");
// 4. 讀取XML文件，載入進相應Object類型
switchXML.readerXML();
}
}

G. 求 Java序列化對象轉xml方法....


/**這里應用了JAVA的Marshall方法
*對象轉xml
*返回xml
*@paramtXLife
*@return
*/
publicstaticStringtXLiftToXML(com.TXLifetXLife){
	Stringxml="";
	try{
			ByteArrayOutputStreamout=newByteArrayOutputStream();
			JAXBContextjc=JAXBContext
					.newInstance("com");//包的命名空間
			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();//賦值
		}catch(Exceptione){
			xml=null;
		}
	returnxml;
}

H. 求助java讀取txt文件轉化為xml形式輸出

txt文件格式如下，採用的是一個服務端tomcat的log日誌

J. 【高分求助】java 中數組格式的 json 怎麼轉成 xml

首先樓主的json數據有問題。

下面代碼親測，可用，兩個文件放在同級目錄：

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"?>
