jwsdp解析xml 范例-转载

jwsdp解析xml 实例-转载
1、安装jwsdp-2_0-windows-i586.exe

2、设置jwsdp环境变量
C:\jwsdp-2.0 安装目录

set JWSDP_HOME=C:\jwsdp-2.0
set JWSDP_JAXB_LIB=%JWSDP_HOME%\jaxb\lib
set JWSDP_SHARED_LIB=%JWSDP_HOME%\jwsdp-shared\lib
set JWSDP_SJSXP_LIB=%JWSDP_HOME%\sjsxp\lib

set CLASSPATH=%JWSDP_JAXB_LIB%\jaxb-api.jar;
              %JWSDP_JAXB_LIB%\jaxb-impl.jar;
              %JWSDP_JAXB_LIB%\jaxb1-impl.jar;
              %JWSDP_JAXB_LIB%\jaxb-xjc.jar;%CLASSPATH%

set CLASSPATH=%JWSDP_SJSXP_LIB%\sjsxp.jar;
              %JWSDP_SJSXP_LIB%\jsr173_api.jar;%CLASSPATH%

set CLASSPATH=%JWSDP_SHARED_LIB%\activation.jar;
              %JWSDP_SHARED_LIB%\resolver.jar;%CLASSPATH%
set PATH=%JWSDP_HOME%\jaxb\bin;%JWSDP_HOME%\jwsdp-shared\bin;%PATH%


3、创建工程

   在工程src目录下建bookxsd.xsd 与 books.xml

books.xml-------------------------------------

   <?xml version="1.0" ?>
<Collection>
<books>
<book itemId="999">

bookxsd.xsd-------------------------------
<?xml version="1.0" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="1.0">

  </xs:schema>



4、生成java文件

    在工程的根目录下执行命令
    D:\workspace\JAXBDemo>xjc -p com.ce -d src src/bookxsd.xsd
    生成4个java文件：
com\ce\BookCategoryType.java
com\ce\BookType.java
com\ce\Collection.java
com\ce\ObjectFactory.java

5、写测试类(解析xml)
import java.io.File;
import java.util.List;

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

import com.ce.BookType;
import com.ce.Collection;
import com.ce.Collection.Books;

public class JAXBTest {

public static void main(String[] args) throws JAXBException {
  JAXBContext jc = JAXBContext.newInstance("com.ce");
  Unmarshaller unmarshaller = jc.createUnmarshaller();
  Collection collection= (Collection)unmarshaller.unmarshal(new File( "src/books.xml"));
  Books books = collection.getBooks();
  List<BookType> bookList = books.getBook();
  for (BookType bookType : bookList) {
   System.out.println(bookType.getName());
  }
}
}
