spring -ws是基于契約先行（contract first）的原則實(shí)現(xiàn)的web service。

自從JDK1.5的annotation出現(xiàn)以后，我偏向于寫注解而不寫xml，所以我在項(xiàng)目中盡量寫注解來替代xml

閑話少說。動(dòng)手做。

必備包：spring.jar ; spring-ws-1.5.8-all.jar ; wsdl4j-1.6.1.jar ; spring-mvc-2.5.6.jar;

XmlSchema-1.4.3.jar ; commons-logging-1.1.1.jar

spring-ws是契約先行，先寫wsdl文件的內(nèi)容，然后生成所需要的java類。

而wsdl是由包含請(qǐng)求和返回以及數(shù)據(jù)xsd文件，使用spring-ws生成的。

這里演示一個(gè)簡(jiǎn)單的spring-ws

一個(gè)人客戶端輸入自己的卡號(hào)，返回這個(gè)人的所有信息。

xsd文件（workerInfo.xsd）

<?xml version="1.0" encoding="UTF-8"?>
< xs:schema xmlns:xs="http://www./2001/XMLSchema"
xmlns:tns="http:///schemas/workerinfo"
elementFormDefault="qualified"
targetNamespace="http:///schemas/workerinfo">

<!--查詢請(qǐng)求，輸入的是一個(gè)字符串的證件號(hào)碼CardNo-->
<xs:element name="WorkerRequest">
<xs:complexType>
<xs:all>
<xs:element name="CardNo" type="xs:string" />
</xs:all>
</xs:complexType>
</xs:element>

<!--數(shù)據(jù)返回，返回的是一個(gè)WorkerInfo數(shù)據(jù)類型-->
<xs:element name="WorkerResponse">
<xs:complexType>
<xs:all>
<xs:element name="WorkerResponse" type="tns:WorkerInfo" />
</xs:all>
</xs:complexType>
</xs:element>

<!--WorkerInfo數(shù)據(jù)類型其實(shí)就是一個(gè)Java類，由下面幾個(gè)屬性組成-->
<xs:complexType name="WorkerInfo">
<xs:sequence>
<xs:element name="id" type="xs:long"></xs:element>
<xs:element name="cardNo" type="xs:string"></xs:element>
<xs:element name="workerName" type="xs:string"></xs:element>
<xs:element name="workerSex" type="xs:string"></xs:element>
</xs:sequence>
</xs:complexType>
< /xs:schema>

對(duì)于spring-ws要配置的地方有

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
< web-app xmlns:xsi="http://www./2001/XMLSchema-instance" xmlns="http://java./xml/ns/javaee" xmlns:web="http://java./xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java./xml/ns/javaee http://java./xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
<display-name>ajjws</display-name>
< servlet>
<servlet-name>ajjws</servlet-name>
<servlet-class>org.springframework.ws.transport.http.MessageDispatcherServlet</servlet-class>
<init-param>
<param-name>transformWsdlLocations</param-name>
<param-value>true</param-value>
</init-param>
</servlet>

<servlet-mapping>
<servlet-name>ajjws</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
</web-app>

ajjws-servlet.xml:(名稱和web.xml的servlet-name相同)

<?xml version="1.0" encoding="UTF-8"?>
< beans xmlns="http://www./schema/beans"
xmlns:xsi="http://www./2001/XMLSchema-instance"
xmlns:context="http://www./schema/context"
xsi:schemaLocation="http://www./schema/beans
http://www./schema/beans/spring-beans-2.5.xsd
http://www./schema/context http://www./schema/context/spring-context-2.5.xsd">

<!--對(duì)com.ajjws下的包里的類自動(dòng)掃描，從而不用定義文件中bean，在類中使用@Service@component等-調(diào)用時(shí)候使用@Resource或者@AutoWired->

<context:annotation-config/>
<context:component-scan base-package="com.ajjws"/>
<!--指定xsd文件的地址-->
<bean id="schemaCollection" class="org.springframework.xml.xsd.commons.CommonsXsdSchemaCollection">

<property name="xsds">
<list>
<value>/WEB-INF/xsds/workerInfo.xsd</value>
</list>
</property>
<property name="inline" value="true"/>
</bean>



<bean class="org.springframework.ws.server.endpoint.adapter.GenericMarshallingMethodEndpointAdapter">
<constructor-arg ref="marshaller" />
</bean>

<!--利用Jaxb2實(shí)現(xiàn)xml到Java的轉(zhuǎn)換-->

<bean id="marshaller" class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="contextPath" value="com.ajjws.beans" />
</bean>

<!--申明我們用注解來實(shí)現(xiàn)請(qǐng)求和Endpoint的映射對(duì)應(yīng)-->

<bean class="org.springframework.ws.server.endpoint.mapping.PayloadRootAnnotationMethodEndpointMapping"/>

<!--通過xsd文件定義wsdl-->
<bean id="ajjws" class="org.springframework.ws.wsdl.wsdl11.DefaultWsdl11Definition">
<property name="schemaCollection" ref="schemaCollection" />
<property name="portTypeName" value="Ajj" />
<property name="locationUri" value="http://localhost:8080/ajjws/services" />
<property name="targetNamespace" value="http:///definitions" />
</bean>

< /beans>

安裝jaxb eclipse插件，在xsd文件上點(diǎn)右鍵，選擇jaxb2.1->run xjc

運(yùn)行后會(huì)在com.ajjws.bean包下通過xsd文件生成的java類

如下所示：

Endpoint：（AjjwsEndpoint.java 響應(yīng)web service的請(qǐng)求的文件）
package com.ajjws.ws;
import javax.annotation.Resource;
import org.springframework.ws.server.endpoint.annotation.Endpoint;
import org.springframework.ws.server.endpoint.annotation.PayloadRoot;
import com.ajjws.beans.ObjectFactory;
import com.ajjws.beans.WorkerInfo;
import com.ajjws.beans.WorkerRequest;
import com.ajjws.beans.WorkerResponse;
import com.ajjws.service.AjjService;
/**
* @author wyf
*
*/
@Endpoint
public class AjjwsEndpoint {

@Resource
private AjjService ajjService;//需配置自動(dòng)掃描bean

@Resource
private ObjectFactory objectFactory;

@PayloadRoot(localPart="WorkerRequest",namespace="http:///schemas/workerinfo")
public WorkerResponse getWorkInfo(WorkerRequest request) {
WorkerResponse response=objectFactory.createWorkerResponse();
WorkerInfo workerInfo=ajjService.getWorkInfo(request.getCardNo());
response.setWorkerResponse(workerInfo);
return response;
}
}

AjjService.java:

package com.ajjws.service;
import com.ajjws.beans.WorkerInfo;
public interface AjjService {
/**
* 獲取證件信息
*/
public WorkerInfo getWorkInfo(String cardNo);
}
AjjServiceImpl.java

package com.ajjws.service;
import org.springframework.stereotype.Service;
import com.ajjws.beans.WorkerInfo;
/**
* @author wyf
*
*/
@Service("ajjService")
public class AjjServiceImpl implements AjjService {
public WorkerInfo getWorkInfo(String cardNo) {
//此處僅為演示，為加入數(shù)據(jù)庫
System.out.println(cardNo);
WorkerInfo worker=new WorkerInfo();
worker.setCardNo("1234");
worker.setId(1);
worker.setWorkerName("wyf");
worker.setWorkerSex("男");
return worker;
}

}

客戶端使用eclipse本身自帶的生成web service client

點(diǎn)擊finish，通過wsdl生成客戶端所需要的Java類

結(jié)構(gòu)如下

客戶端調(diào)用代碼：

package com.ajjSearch.web;
import java.rmi.RemoteException;
import org.springframework.ws.client.core.support.WebServiceGatewaySupport;

import com.ajjws.definitions.AjjProxy;
import com.ajjws.schemas.workerinfo.WorkerInfo;
import com.ajjws.schemas.workerinfo.WorkerRequest;
import com.ajjws.schemas.workerinfo.WorkerResponse;

public class WsClient extends WebServiceGatewaySupport{
public static void main(String[] args) throws RemoteException {
doSomething();
}

public static void doSomething() throws RemoteException{
WorkerRequest wreq=new WorkerRequest("1111");
WorkerResponse wres=new AjjProxy().getAjj().worker(wreq);
System.out.println(wres.getWorkerResponse());
WorkerInfo wi=wres.getWorkerResponse();
System.out.println(wi.getCardNo()+" "+wi.getId()+" "+wi.getWorkerName()+" "+wi.getWorkerSex());
}
}
