axis部署WebServices 和 JAXB的运用 (二)-优快云博客

三、JAXB的运用：

1、新建一个xml schema文件 po.xsd：

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">

<xsd:element name="purchaseOrder" type="PurchaseOrderType"/>

<xsd:element name="comment" type="xsd:string"/>

<xsd:complexType name="PurchaseOrderType">

<xsd:sequence>

<xsd:element name="shipTo" type="USAddress"/>

<xsd:element name="billTo" type="USAddress"/>

<xsd:element ref="comment" minOccurs="0"/>

<xsd:element name="items" type="Items"/>

</xsd:sequence>

<xsd:attribute name="orderDate" type="xsd:date"/>

</xsd:complexType>

<xsd:complexType name="USAddress">

<xsd:sequence>

<xsd:element name="name" type="xsd:string"/>

<xsd:element name="street" type="xsd:string"/>

<xsd:element name="city" type="xsd:string"/>

<xsd:element name="state" type="xsd:string"/>

<xsd:element name="zip" type="xsd:decimal"/>

</xsd:sequence>

<xsd:attribute name="country" type="xsd:NMTOKEN" fixed="US"/>

</xsd:complexType>

<xsd:complexType name="Items">

<xsd:sequence>

<xsd:element name="item" minOccurs="1" maxOccurs="unbounded">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="productName" type="xsd:string"/>

<xsd:element name="quantity">

<xsd:simpleType>

<xsd:restriction base="xsd:positiveInteger">

<xsd:maxExclusive value="100"/>

</xsd:restriction>

</xsd:simpleType>

</xsd:element>

<xsd:element name="USPrice" type="xsd:decimal"/>

<xsd:element ref="comment" minOccurs="0"/>

<xsd:element name="shipDate" type="xsd:date" minOccurs="0"/>

</xsd:sequence>

<xsd:attribute name="partNum" type="SKU" use="required"/>

</xsd:complexType>

</xsd:element>

</xsd:sequence>

</xsd:complexType>

<xsd:simpleType name="SKU">

<xsd:restriction base="xsd:string">

<xsd:pattern value="d{3}-[A-Z]{2}"/>

</xsd:restriction>

</xsd:simpleType>

</xsd:schema>

2、生成XML Schema 文件对应的类：

（1）在环境变量的系统变量的PATH中加入 <jwsdp安装目录>/jaxb/bin，（我的是C:/jwsdp-2.0/jaxb/bin;）然后以命令行的形式运行：

…./xjc po.xsd -d src -p epri.jaxb

其中

·po.xsd 是Schema的文件名；

·-d 的选项，是指定系统生成的Java源代码所放置的目录；

·-p 的选项，是指定系统生成的Java源代码所在的Java Package的名称。

注：-d 和 -p 都可以不写,直接运行： xjc po.xsd （不建议）

例如：我们将po.xsd 放于C盘根目录下：

可以看到生成了两个java文件，它们就是po.xsd对应的实体类。

（2）编写一个ant文件，用于在工程中直接生成XML Schema 文件对就的类，如下：

<?xml version="1.0"?>

</path>

</taskdef>

</target>

</project>

Run As -> Ant Build XML Schema就可以生成对应的实体类，当然po.sxd 和 build.xml都应位于工程的根目录下！

3、写一个测试的java文件

Main.java:

import java.io.FileOutputStream;

import java.io.IOException;

import java.math.BigDecimal;

import java.math.BigInteger;

import java.util.GregorianCalendar;

import java.util.List;

import javax.xml.bind.JAXBContext;

import javax.xml.bind.JAXBElement;

import javax.xml.bind.JAXBException;

import javax.xml.bind.Marshaller;

import javax.xml.bind.*;

import javax.xml.datatype.DatatypeFactory;

import javax.xml.datatype.XMLGregorianCalendar;

import javax.xml.datatype.DatatypeConfigurationException;

import primer.po.*;

public class Main{

public static void main( String[] args ) {

try {

JAXBContext jc = JAXBContext.newInstance( "primer.po" );

PurchaseOrderType po = new PurchaseOrderType();

po.setOrderDate( getDate() );

USAddress shipTo = createUSAddress( "Alice Smith",

"123 Maple Street",

"Cambridge",

"MA",

"12345" );

po.setShipTo( shipTo );

USAddress billTo = createUSAddress( "Robert Smith",

"8 Oak Avenue",

"Cambridge",

"MA",

"12345" );

po.setBillTo( billTo );

Items items = new Items();

List<Items.Item> itemList = items.getItem();

// start adding ItemType objects into it

itemList.add( createItem( "Nosferatu - Special Edition (1929)",

new BigInteger( "5" ),

new BigDecimal( "19.99" ),

null,

"242-NO" ) );

itemList.add( createItem( "The Mummy (1959)",

new BigInteger( "3" ),

new BigDecimal( "19.98" ),

null,

"242-MU" ) );

itemList.add( createItem( "Godzilla and Mothra: Battle for Earth/Godzilla vs. King Ghidora",

new BigInteger( "3" ),

new BigDecimal( "27.95" ),

null,

"242-GZ" ) );

po.setItems( items );

JAXBElement<PurchaseOrderType> poElement = (new ObjectFactory()).createPurchaseOrder(po);

Marshaller m = jc.createMarshaller();

m.setProperty( Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE );

m.marshal(poElement, new FileOutputStream("test.xml"));

m.marshal(poElement, System.out);

} catch( JAXBException je ){

je.printStackTrace();

} catch( IOException ioe ) {

ioe.printStackTrace();

}

public static USAddress createUSAddress( String name, String street,

String city, String state,

String zip ) {

USAddress address = new USAddress();

address.setName( name );

address.setStreet( street );

address.setCity( city );

address.setState( state );

address.setZip( new BigDecimal( zip ) );

return address;

}

public static Items.Item createItem( String productName,

BigInteger quantity,

BigDecimal price,

String comment,

XMLGregorianCalendar shipDate,

String partNum ) {

Items.Item item = new Items.Item();

item.setProductName( productName );

item.setQuantity( quantity );

item.setUSPrice( price );

item.setComment( comment );

item.setShipDate( shipDate );

item.setPartNum( partNum );

return item;

}

private static XMLGregorianCalendar getDate() {

try {

return DatatypeFactory.newInstance().newXMLGregorianCalendar(new GregorianCalendar());

} catch (DatatypeConfigurationException e) {

throw new Error(e);

}

用Java Application运行 SayHelloClient.java

输出结果：

在axisweb工程根目录下生成了一个test.xml 的文件，内容和上面一样！
