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

若要生成该结构的xml文件，则XML Schema文件应编写为

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 
     
        2   3   
      
         4     
       
        com.xmlbeans
         5   
        6   7

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

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xml25      * @param xml文件26      * @return userBean27      */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user39         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]]]
