• XML工具——xmlbeans的使用


    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:Javajdk1.7.0_80

    (2)配置XMLBEANS_HOME:D:xmlbeans-2.6.0

    (3)在path中添加%JAVA_HOME%in和%XMLBEANS_HOME%in

    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]]]

    六、附录

    6.1 项目结构

    6.2 com.pojo下的类
