JAXB(.xsd文件到java类的映射)

JAXB的Eclipse插件（.xsd文件到java类的映射）

 

一、JAXB的Eclipse插件的下载地址： https://jaxb-workshop.dev.java.net/servlets/ProjectDocumentList?folderID=4962&expandFolder=4962&folderID=0

二、插件的使用说明： https://jaxb-workshop.dev.java.net/plugins/eclipse/xjc-plugin.html

三、实例

1、databaseInfo.xsd文件

<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema "
targetNamespace="http://www.w3school.com.cn " xmlns="http://www.w3school.com.cn "
elementFormDefault="qualified">

<xs:element name="database">
   <xs:complexType>
    <xs:sequence>
     <xs:element name="info" maxOccurs="unbounded">
      <xs:complexType>
       <xs:sequence>
        <xs:element name="ip" type="xs:string" />
        <xs:element name="port" type="xs:string" />
        <xs:element name="databaseName" type="xs:string" />
        <xs:element name="userName" type="xs:string" />
        <xs:element name="password" type="xs:string" />
       </xs:sequence>
      </xs:complexType>
     </xs:element>
    </xs:sequence>
   </xs:complexType>
</xs:element>

</xs:schema>

2、右键点击“databaseInfo.xsd”文件

3、下一步

4、下一步

5、“Finish”之后

6、刷新项目

7、xmlOperation.java对XML的读写操作

package com.channelsoft.xml.operation;

import java.io.File;

import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import javax.xml.bind.Unmarshaller;

import com.channelsoft.xml.Database;
import com.channelsoft.xml.ObjectFactory;

public class xmlOperation
{
/**
*从XML文件读
*/
public void readFromXML()
{
   JAXBContext jc;
   try
   {
    jc = JAXBContext.newInstance("com.channelsoft.xml");
    Unmarshaller u = jc.createUnmarshaller();
    Database info = (Database) u.unmarshal(new File("e:\\info.xml"));
   
    for(int i=0;i<info.getInfo().size();i++)
    {
     System.out.println(info.getInfo().get(i).getIp());
     System.out.println(info.getInfo().get(i).getPort());
     System.out.println(info.getInfo().get(i).getDatabaseName());
     System.out.println(info.getInfo().get(i).getUserName());
     System.out.println(info.getInfo().get(i).getPassword());
    }
   
   }
   catch (JAXBException e)
   {
    e.printStackTrace();
   }
  
}

/**
* 创建并写入XML文件
*/
public void saveToXML()
{
   try
   {
    ObjectFactory of = new ObjectFactory();
    Database database = of.createDatabase();
    Database.Info info= of.createDatabaseInfo();
   
    info.setIp("10.130.14.142");
    info.setPort("1433");
    info.setDatabaseName("hrinfo");
    info.setUserName("sa");
    info.setPassword("dibin");
   
    Database.Info info1= of.createDatabaseInfo();
   
    info1.setIp("10.130.14.49");
    info1.setPort("1433");
    info1.setDatabaseName("hrinfo");
    info1.setUserName("sa11");
    info1.setPassword("dibin11");
   
    database.getInfo().add(info);
    database.getInfo().add(info1);
   
    JAXBContext jc = JAXBContext.newInstance("com.channelsoft.xml");
    Marshaller ms = jc.createMarshaller();
    ms.setProperty("jaxb.encoding", "GB2312");
    ms.setProperty("jaxb.formatted.output", true);
    ms.marshal(database, new File("e:\\info.xml"));
   }
   catch (Exception e)
   {
   
   }
}

public static void main(String[] args)
{
   new xmlOperation().saveToXML();
   new xmlOperation().readFromXML();
}
}
