How-Tos_Writing a service with spring

使用spring构件第一个Web服务，项目名java_first_spring_support

构件项目

编写服务

接口：

<span style="font-size:18px;">import javax.jws.WebService;

@WebService
public interface HelloWorld {
String sayHi(String text);
}</span>
接口实现：

<span style="font-size:18px;">import javax.jws.WebService;

@WebService(endpointInterface = "demo.spring.service.HelloWorld")
public class HelloWorldImpl implements HelloWorld {

public String sayHi(String text) {
System.out.println("sayHi called");
return "Hello " + text;
}
}</span>

实现类的@ webservice注释让CXF知道使用哪个接口在创建WSDL。

声明服务的beans

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">
<import resource="classpath:META-INF/cxf/cxf.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>
<jaxws:endpoint id="helloWorld" implementor="demo.spring.service.HelloWorldImpl" address="/HelloWorld"/>
</beans>
配置servlet

例子：

<web-app ...>
...
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/beans.xml</param-value>
</context-param>

<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
</web-app>


创建客户端（easy way）

客户端bean

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:jaxws="http://cxf.apache.org/jaxws"
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.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd">

<jaxws:client id="helloClient"
serviceClass="demo.spring.HelloWorld"
address="http://localhost:9002/HelloWorld" />
</beans>
创建客户端(More Manual Way)

使用JaxWsProxyFactory从服务接口创建一个客户端

客户端bean:

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schema/jaxws.xsd">
<bean id="client" class="demo.spring.service.HelloWorld" factory-bean="clientFactory" factory-method="create"/>
<bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="demo.spring.service.HelloWorld"/>
<property name="address" value="http://localhost:9002/services/HelloWorld"/>
</bean>
</beans>
客户端代码：
<pre name="code" class="html">ApplicationContext context = ...; // your Spring ApplicationContext
HelloWorld client = (HelloWorld) context.getBean("client");
