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
<?xml version="1.0" encoding="UTF-8"?>
<user>
<username></username>
<password></password>
<age></age>
<addresses>
<Chinese>
<nationality></nationality>
<cityProvince></cityProvince>
<district></district>
<address></address>
</Chinese>
<English>
<nationality></nationality>
<cityProvince></cityProvince>
<district></district>
<address></address>
</English>
</addresses>
</user>
若要生成该结构的xml文件，则XML Schema文件应编写为
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="unqualified">
<!-- 根节点user -->
<xs:element name="user">
<xs:complexType>
<xs:sequence>
<!-- user子节点username 类型为String -->
<xs:element name="username" type="xs:string"/>
<!-- user子节点password 类型为String -->
<xs:element name="password" type="xs:string"/>
<!-- user子节点age 类型为BigDecimal(数字类型 不推荐使用 此处为举例) -->
<xs:element name="age" type="xs:decimal"/>
<!-- user子节点addresses 类型为自定义类型AddressesType -->
<xs:element name="addresses" type="AddressesType"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<!-- 自定义类型AddressesType -->
<xs:complexType name="AddressesType">
<xs:sequence>
<!-- addresses子节点Chinese 类型为自定义类型AddressType -->
<xs:element name="Chinese" type="AddressType"/>
<!-- addresses子节点English 类型为自定义类型AddressType -->
<xs:element name="English" type="AddressType"/>
</xs:sequence>
</xs:complexType>
<!-- 自定义类型AddressType -->
<xs:complexType name="AddressType">
<xs:sequence>
<!-- address子节点nationality 类型为String类型 -->
<xs:element name="nationality" type="xs:string"/>
<!-- address子节点cityProvince 类型为String类型 -->
<xs:element name="cityProvince" type="xs:string"/>
<!-- address子节点district 类型为String类型 -->
<xs:element name="district" type="xs:string"/>
<!-- address子节点address 类型为String类型 -->
<xs:element name="address" type="xs:string"/>
</xs:sequence>
</xs:complexType>
</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
<xb:config xmlns:xb="http://xml.apache.org/xmlbeans/2004/02/xbean/config"> <xb:namespace>
<xb:package>com.xmlbeans</xb:package>
</xb:namespace> </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
package com.xbean; import java.io.File;
import java.io.IOException;
import java.math.BigDecimal; import com.pojo.*;
import com.xmlbeans.*;
import com.xmlbeans.UserDocument.User; public class BuildXml { public static void main(String[] args) { UserBean userBean = getUser(); //生成DOM对象
UserDocument doc = UserDocument.Factory.newInstance();
//生成根节点user
User user = doc.addNewUser(); //user子节点username
user.setUsername(userBean.getUsername());
//user子节点password
user.setPassword(userBean.getPassword());
//user子节点age
user.setAge(userBean.getAge()); //生成user子节点addresses
AddressesType addresses = user.addNewAddresses();
AddressesBean addressesBean = userBean.getAddresses(); //生成addresses子节点chinese
AddressType chinese = addresses.addNewChinese();
AddressBean chineseAddress = addressesBean.getChinese();
//chinese子节点nationality
chinese.setNationality(chineseAddress.getNationality());
//chinese子节点cityProvince
chinese.setCityProvince(chineseAddress.getCityProvince());
//chinese子节点district
chinese.setDistrict(chineseAddress.getDistrict());
//chinese子节点address
chinese.setAddress(chineseAddress.getAddress()); //生成addresses子节点english
AddressType english = addresses.addNewEnglish();
AddressBean englishAdress = addressesBean.getEnglish();
//english子节点nationality
english.setNationality(englishAdress.getNationality());
//english子节点cityProvince
english.setCityProvince(englishAdress.getCityProvince());
//english子节点district
english.setDistrict(englishAdress.getDistrict());
//english子节点address
english.setAddress(englishAdress.getAddress()); //构造的xml文件
File xml = new File("user.xml");
try {
//保存
doc.save(xml);
} catch (IOException e) {
System.out.println("user.xml生成失败");
e.printStackTrace();
}
System.out.println("user.xml生成结束"); } /**
* 模拟实际环境 生成获取UserBean实体类对象
* @return user
*/
public static UserBean getUser(){
UserBean user = new UserBean();
user.setUsername("张三");
user.setPassword("123");
user.setAge(new BigDecimal("20")); AddressBean chinese = new AddressBean();
chinese.setNationality("中国");
chinese.setCityProvince("浙江");
chinese.setDistrict("杭州");
chinese.setAddress("123456"); AddressBean english = new AddressBean();
english.setNationality("Chinese");
english.setCityProvince("ZheJiang");
english.setDistrict("HangZhou");
english.setAddress("654321"); AddressesBean addresses = new AddressesBean();
addresses.setChinese(chinese);
addresses.setEnglish(english); user.setAddresses(addresses); return user;
} }
运行，结束后获得生成的user.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<user>
<username>张三</username>
<password>123</password>
<age>20</age>
<addresses>
<Chinese>
<nationality>中国</nationality>
<cityProvince>浙江</cityProvince>
<district>杭州</district>
<address>123456</address>
</Chinese>
<English>
<nationality>Chinese</nationality>
<cityProvince>ZheJiang</cityProvince>
<district>HangZhou</district>
<address>654321</address>
</English>
</addresses>
</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
package com.xbean; import java.io.File; import com.pojo.AddressBean;
import com.pojo.AddressesBean;
import com.pojo.UserBean;
import com.xmlbeans.AddressType;
import com.xmlbeans.AddressesType;
import com.xmlbeans.UserDocument;
import com.xmlbeans.UserDocument.User; public class ParseXml { public static void main(String[] args) {
//解析的xml文件
File xml = new File("user.xml");
UserBean user = parseXml(xml); System.out.println(user);
} /**
* 解析xml
* @param xml文件
* @return userBean
*/
public static UserBean parseXml(File xml){
UserBean userBean = new UserBean();
UserDocument doc = null;
try {
//解析xml获取DOM对象
doc = UserDocument.Factory.parse(xml);
} catch (Exception e) {
System.out.println("解析异常");
e.printStackTrace();
}
//获取根节点user
User user = doc.getUser(); //将xml中的值set进userBean对象中
userBean.setUsername(user.getUsername());
userBean.setPassword(user.getPassword());
userBean.setAge(user.getAge()); AddressesType addresses = user.getAddresses();
AddressesBean addressesBean = userBean.getAddresses(); AddressType chinese = addresses.getChinese();
AddressBean chineseBean = addressesBean.getChinese();
chineseBean.setNationality(chinese.getNationality());
chineseBean.setCityProvince(chinese.getCityProvince());
chineseBean.setDistrict(chinese.getDistrict());
chineseBean.setAddress(chinese.getAddress()); AddressType english = addresses.getEnglish();
AddressBean englishBean = addressesBean.getEnglish();
englishBean.setNationality(english.getNationality());
englishBean.setCityProvince(english.getCityProvince());
englishBean.setDistrict(english.getDistrict());
englishBean.setAddress(english.getAddress()); return userBean;
} }
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]]]
