axis部署WebServices 和 JAXB的运用 (二)

导读：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:complexT

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>jaxbbin，（我的是C:jwsdp-2.0jaxbbin;）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：

<? xmlversion="1.0" ?>

< project basedir ="." default ="compile" >

< property name ="jwsdp.home" value ="C:jwsdp-2.0" />

< path id ="classpath" >

< pathelement path ="build" />

< fileset dir ="${jwsdp.home}" includes ="jaxb/lib/*.jar" />

< fileset dir ="${jwsdp.home}" includes ="jwsdp-shared/lib/*.jar" />

< fileset dir ="${jwsdp.home}" includes ="jaxp/lib/**/*.jar" />

</ path >

< taskdef name ="xjc" classname ="com.sun.tools.xjc.XJCTask" >

< classpath refid ="classpath" />

</ taskdef >

< target name ="compile" >

< echo message ="Compilingtheschemaexternalbindingfile..." />

< xjc schema ="po.xsd" package ="primer.po" target ="src" />

< echo message ="Compilingthejavasourcefiles..." />

</ 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 {

publicstaticvoidmain(String[]args){

try{

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

PurchaSEOrderTypepo=newPurchaSEOrderType();

po.setOrderDate(getDate());

USAddressshipTo=createUSAddress("AliceSmith",

"123MapleStreet",

"Cambridge",

"MA",

"12345");

po.setShipTo(shipTo);

USAddressbillTo=createUSAddress("RobertSmith",

"8OakAvenue",

"12345");

po.setBillTo(billTo);

Itemsitems=newItems();

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

//startaddingItemTypeobjectsintoit

itemList.add(createItem("Nosferatu-SpecialEdition(1929)",

newBigInteger("5"),

newBigDecimal("19.99"),

null,

"242-NO"));

itemList.add(createItem("TheMummy(1959)",

newBigInteger("3"),

newBigDecimal("19.98"),

"242-MU"));

itemList.add(createItem("GodzillaandMothra:BattleforEarth/Godzillavs.KingGhidora",

newBigDecimal("27.95"),

"242-GZ"));

po.setItems(items);

JAXBElement<PurchaSEOrderType>poElement=(newObjectFactory()).createPurchaSEOrder(po);

Marshallerm=jc.createMarshaller();

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

m.marshal(poElement,newFileOutputStream("test.xml"));

m.marshal(poElement,System.out);

}catch(JAXBExceptionje){

je.printStackTrace();

}catch(IOExceptionioe){

ioe.printStackTrace();

}

publicstaticUSAddresscreateUSAddress(Stringname,Stringstreet,

Stringcity,Stringstate,

Stringzip){

USAddressaddress=newUSAddress();

address.setName(name);

address.setStreet(street);

address.setCity(city);

address.setState(state);

address.setZip(newBigDecimal(zip));

returnaddress;

}

publicstaticItems.ItemcreateItem(StringproductName,

BigIntegerquantity,

BigDecimalprice,

Stringcomment,

XMLGregorianCalendarshipDate,

StringpartNum){

Items.Itemitem=newItems.Item();

item.setProductName(productName);

item.setQuantity(quantity);

item.setUSPrice(price);

item.setComment(comment);

item.setShipDate(shipDate);

item.setPartNum(partNum);

returnitem;

}

privatestaticXMLGregorianCalendargetDate(){

try{

returnDatatypeFactory.newInstance().newXMLGregorianCalendar(newGregorianCalendar());

}catch(DatatypeConfigurationExceptione){

thrownewError(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！
