一、安装xmlbeans
1.下载xmlbeans
下载地址：https://gitee.com/shizuru/xmlbeans-2.6.0
2.解压，此处以解压至D盘根目录为例
3.配置环境变量（路径不能有中文或空格）
（1）配置JAVA_HOME：D:\\Java\\jdk1.7.0_80
（2）配置XMLBEANS_HOME：D:\\xmlbeans-2.6.0
（3）在path中添加%JAVA_HOME%\\bin和%XMLBEANS_HOME%\\bin
4.验检查安装结果
打开cmd输入scomp -version，如下即安装成功
二、编写XML Schema及其配置文件
2.1 XML Schema文件
XML Schema（后缀为.xsd）是基于XML的DTD替代者，可描述XML文档的结构。它定义了XML文件的结构和元素以及对元素和结构的约束。
以下述User.xml为例
1 <?xml version="1.0" encoding="UTF-8"?> 2 <user> 3 <username></username> 4 <password></password> 5 <age></age> 6 <addresses> 7 <Chinese> 8 <nationality></nationality> 9 <cityProvince></cityProvince> 10 <district></district> 11 <address></address> 12 </Chinese> 13 <English> 14 <nationality></nationality> 15 <cityProvince></cityProvince> 16 <district></district> 17 <address></address> 18 </English> 19 </addresses> 20 </user>
若要生成该结构的xml文件，则XML Schema文件应编写为
1 <?xml version="1.0" encoding="UTF-8"?> 2 <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified"> 3 <!-- 根节点user --> 4 <xs:element name="user"> 5 <xs:complexType> 6 <xs:sequence> 7 <!-- user子节点username 类型为String --> 8 <xs:element name="username" type="xs:string"/> 9 <!-- user子节点password 类型为String --> 10 <xs:element name="password" type="xs:string"/> 11 <!-- user子节点age 类型为BigDecimal(数字类型 不推荐使用 此处为举例) --> 12 <xs:element name="age" type="xs:decimal"/> 13 <!-- user子节点addresses 类型为自定义类型AddressesType --> 14 <xs:element name="addresses" type="AddressesType"/> 15 </xs:sequence> 16 </xs:complexType> 17 </xs:element> 18 <!-- 自定义类型AddressesType --> 19 <xs:complexType name="AddressesType"> 20 <xs:sequence> 21 <!-- addresses子节点Chinese 类型为自定义类型AddressType --> 22 <xs:element name="Chinese" type="AddressType"/> 23 <!-- addresses子节点English 类型为自定义类型AddressType --> 24 <xs:element name="English" type="AddressType"/> 25 </xs:sequence> 26 </xs:complexType> 27 <!-- 自定义类型AddressType --> 28 <xs:complexType name="AddressType"> 29 <xs:sequence> 30 <!-- address子节点nationality 类型为String类型 --> 31 <xs:element name="nationality" type="xs:string"/> 32 <!-- address子节点cityProvince 类型为String类型 --> 33 <xs:element name="cityProvince" type="xs:string"/> 34 <!-- address子节点district 类型为String类型 --> 35 <xs:element name="district" type="xs:string"/> 36 <!-- address子节点address 类型为String类型 --> 37 <xs:element name="address" type="xs:string"/> 38 </xs:sequence> 39 </xs:complexType> 40 </xs:schema>
2.2 配置文件
xsd配置文件（后缀为. xsdconfig）主要用来制定生成的Java Class的一些文件名规则和Package的名称
如下所示，生成的包名为com.xmlbeans
1 <xb:config xmlns:xb="http://xml.apache.org/xmlbeans/2004/02/xbean/config"> 2 3 <xb:namespace> 4 <xb:package>com.xmlbeans</xb:package> 5 </xb:namespace> 6 7 </xb:config>
三、生成jar包
以上编写的2个文件放置路径为D:/Java目录下
打开cmd，输入 scomp -out D:/Java/User.jar D:/Java/User.xsd -compiler D:/Java/jdk1.7.0_80/bin/javac D:/Java/User.xsdconfig
该命令的语法格式如下
scomp [options] [dirs]* [schemaFile.xsd]* [service.wsdl]* [config.xsdconfig]*
主要参数说明：
-src [dir] -- 生成的Java Classes存放目录
-srconly -- 不编译Java Classes,不产生Jar文件
-out [jarFileName] -- 生成的Jar文件,缺省是xmltypes.jar
-compiler -- Java编译器的路径,即Javac的位置
schemaFile.xsd -- XML Schema文件位置
config.xsdconfig -- xsdconfig文件的位置
因此，命令的意思为在D:/Java目录下生成User.jar，使用的XML Schema为D:/Java目录下的User.xsd，其配置文件为D:/Java目录下的User.xsdconfig，使用的编译器为D:/Java/jdk1.7.0_80/bin/javac
成功运行如下图所示
再次查看D:/Java目录，发现多了一个User.jar
四、构造xml文件
将生成的jar包导入项目，同时也需要依赖jar包xbean.jar，下载地址：https://gitee.com/shizuru/xmlbeans-2.6.0
编写构造类
1 package com.xbean; 2 3 import java.io.File; 4 import java.io.IOException; 5 import java.math.BigDecimal; 6 7 import com.pojo.*; 8 import com.xmlbeans.*; 9 import com.xmlbeans.UserDocument.User; 10 11 public class BuildXml { 12 13 public static void main(String[] args) { 14 15 UserBean userBean = getUser(); 16 17 //生成DOM对象 18 UserDocument doc = UserDocument.Factory.newInstance(); 19 //生成根节点user 20 User user = doc.addNewUser(); 21 22 //user子节点username 23 user.setUsername(userBean.getUsername()); 24 //user子节点password 25 user.setPassword(userBean.getPassword()); 26 //user子节点age 27 user.setAge(userBean.getAge()); 28 29 //生成user子节点addresses 30 AddressesType addresses = user.addNewAddresses(); 31 AddressesBean addressesBean = userBean.getAddresses(); 32 33 //生成addresses子节点chinese 34 AddressType chinese = addresses.addNewChinese(); 35 AddressBean chineseAddress = addressesBean.getChinese(); 36 //chinese子节点nationality 37 chinese.setNationality(chineseAddress.getNationality()); 38 //chinese子节点cityProvince 39 chinese.setCityProvince(chineseAddress.getCityProvince()); 40 //chinese子节点district 41 chinese.setDistrict(chineseAddress.getDistrict()); 42 //chinese子节点address 43 chinese.setAddress(chineseAddress.getAddress()); 44 45 //生成addresses子节点english 46 AddressType english = addresses.addNewEnglish(); 47 AddressBean englishAdress = addressesBean.getEnglish(); 48 //english子节点nationality 49 english.setNationality(englishAdress.getNationality()); 50 //english子节点cityProvince 51 english.setCityProvince(englishAdress.getCityProvince()); 52 //english子节点district 53 english.setDistrict(englishAdress.getDistrict()); 54 //english子节点address 55 english.setAddress(englishAdress.getAddress()); 56 57 //构造的xml文件 58 File xml = new File("user.xml"); 59 try { 60 //保存 61 doc.save(xml); 62 } catch (IOException e) { 63 System.out.println("user.xml生成失败"); 64 e.printStackTrace(); 65 } 66 System.out.println("user.xml生成结束"); 67 68 } 69 70 /** 71 * 模拟实际环境 生成获取UserBean实体类对象 72 * @return user 73 */ 74 public static UserBean getUser(){ 75 UserBean user = new UserBean(); 76 user.setUsername("张三"); 77 user.setPassword("123"); 78 user.setAge(new BigDecimal("20")); 79 80 AddressBean chinese = new AddressBean(); 81 chinese.setNationality("中国"); 82 chinese.setCityProvince("浙江"); 83 chinese.setDistrict("杭州"); 84 chinese.setAddress("123456"); 85 86 AddressBean english = new AddressBean(); 87 english.setNationality("Chinese"); 88 english.setCityProvince("ZheJiang"); 89 english.setDistrict("HangZhou"); 90 english.setAddress("654321"); 91 92 AddressesBean addresses = new AddressesBean(); 93 addresses.setChinese(chinese); 94 addresses.setEnglish(english); 95 96 user.setAddresses(addresses); 97 98 return user; 99 } 100 101 }
运行，结束后获得生成的user.xml文件
1 <?xml version="1.0" encoding="UTF-8"?> 2 <user> 3 <username>张三</username> 4 <password>123</password> 5 <age>20</age> 6 <addresses> 7 <Chinese> 8 <nationality>中国</nationality> 9 <cityProvince>浙江</cityProvince> 10 <district>杭州</district> 11 <address>123456</address> 12 </Chinese> 13 <English> 14 <nationality>Chinese</nationality> 15 <cityProvince>ZheJiang</cityProvince> 16 <district>HangZhou</district> 17 <address>654321</address> 18 </English> 19 </addresses> 20 </user>
五、解析xml文件
以四中构造获得的user.xml为例进行解析
编写解析类
1 package com.xbean; 2 3 import java.io.File; 4 5 import com.pojo.AddressBean; 6 import com.pojo.AddressesBean; 7 import com.pojo.UserBean; 8 import com.xmlbeans.AddressType; 9 import com.xmlbeans.AddressesType; 10 import com.xmlbeans.UserDocument; 11 import com.xmlbeans.UserDocument.User; 12 13 public class ParseXml { 14 15 public static void main(String[] args) { 16 //解析的xml文件 17 File xml = new File("user.xml"); 18 UserBean user = parseXml(xml); 19 20 System.out.println(user); 21 } 22 23 /** 24 * 解析xml 25 * @param xml文件 26 * @return userBean 27 */ 28 public static UserBean parseXml(File xml){ 29 UserBean userBean = new UserBean(); 30 UserDocument doc = null; 31 try { 32 //解析xml获取DOM对象 33 doc = UserDocument.Factory.parse(xml); 34 } catch (Exception e) { 35 System.out.println("解析异常"); 36 e.printStackTrace(); 37 } 38 //获取根节点user 39 User user = doc.getUser(); 40 41 //将xml中的值set进userBean对象中 42 userBean.setUsername(user.getUsername()); 43 userBean.setPassword(user.getPassword()); 44 userBean.setAge(user.getAge()); 45 46 AddressesType addresses = user.getAddresses(); 47 AddressesBean addressesBean = userBean.getAddresses(); 48 49 AddressType chinese = addresses.getChinese(); 50 AddressBean chineseBean = addressesBean.getChinese(); 51 chineseBean.setNationality(chinese.getNationality()); 52 chineseBean.setCityProvince(chinese.getCityProvince()); 53 chineseBean.setDistrict(chinese.getDistrict()); 54 chineseBean.setAddress(chinese.getAddress()); 55 56 AddressType english = addresses.getEnglish(); 57 AddressBean englishBean = addressesBean.getEnglish(); 58 englishBean.setNationality(english.getNationality()); 59 englishBean.setCityProvince(english.getCityProvince()); 60 englishBean.setDistrict(english.getDistrict()); 61 englishBean.setAddress(english.getAddress()); 62 63 return userBean; 64 } 65 66 }
输出结果：UserBean [username=张三, password=123, age=20, addresses=AddressesBean [chinese=AddressBean [nationality=中国, cityProvince=浙江, district=杭州, address=123456], english=AddressBean [nationality=Chinese, cityProvince=ZheJiang, district=HangZhou, address=654321]]]
