Spring Web Service 学习之Hello World篇2

6, 修改配置文件spring-ws-servlet.xml.

Java代码



<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<bean id="payloadMapping" class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping">

<property name="endpointMap">

<map>

<entry key=”{http://www.fuxueliang.com/ws/hello}HelloRequest” />

<ref bean="helloEndpoint" />

</entry>

</map>

</property>

</bean>

<bean id="hello" class="org.springframework.ws.wsdl.wsdl11.SimpleWsdl11Definition">

<property name="wsdl" value="/WEB-INF/hello.wsdl"/>

</bean>

<bean id="helloEndpoint" class="org.rondy.ws.HelloEndPoint">

<property name="helloService" ref="helloService" />

</bean>

<bean id="helloService" class="org.rondy.service.HelloServiceImpl" />

</beans>

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">   <bean id="payloadMapping" class="org.springframework.ws.server.endpoint.mapping.PayloadRootQNameEndpointMapping">   <property name="endpointMap">    <map>     <entry key=”{http://www.fuxueliang.com/ws/hello}HelloRequest” />        <ref bean="helloEndpoint" />     </entry>    </map>   </property>  </bean>  <bean id="hello" class="org.springframework.ws.wsdl.wsdl11.SimpleWsdl11Definition">   <property name="wsdl" value="/WEB-INF/hello.wsdl"/>  </bean>  <bean id="helloEndpoint" class="org.rondy.ws.HelloEndPoint">   <property name="helloService" ref="helloService" />  </bean>  <bean id="helloService" class="org.rondy.service.HelloServiceImpl" /> </beans>

注: 其中最主要的bean就是payloadMapping, 它定义了接收到的message与endpoint之间的mapping关系:将SOAP Body中包含的xml的根节点的QName为{http://www.fuxueliang.com/ws/hello}HelloRequest交给helloEndpoint处理.

SimpleWsdl11Definition这个bean则是定义了这个服务的wsdl, 访问地址是:http://localhost:8080/springws/hello.wsdl.

7, 客户端(saaj实现)的代码如下:

Java代码

几点看法:

1, 从上面代码可以看出, 比较麻烦的部分就是客户端和服务端对xml处理
