CXF系列之JAX-WS：与Spring3集成并在tomcat部署

虽然网上的资料很多，但自己还是有必要记录一下，毕竟自己整理的，查询容易，对以后也方便

该集成是基于CXF3.0的。

web service 接口和实现类，都很简单，仅仅是为了测试环境，是否搭建成功。

package com.test.service.inter;

import javax.jws.WebService;

@WebService
public interface HelloService {

public String sayHello(String name);
}

package com.test.service.impl;

import com.test.service.inter.HelloService;

public class HelloServiceImpl implements HelloService {

@Override
public String sayHello(String name) {
return "您好："+name;
}

}

spring配置文件：spring.xml，主要有两个功能：1、spring相关配置2、引入spring与cxf集成文件

第一种方式：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context   http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 
<import resource="spring-cxf.xml" />

</beans>

spring与cxf集成文件：spring-cxf.xml

<?xml version="1.0" encoding="UTF-8"?>
<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-3.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"> 
<jaxws:endpoint id="helloService" implementor="com.test.service.impl.HelloServiceImpl" address="/hello"/>

</beans>

第二种方式：是由Spring装配bean

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context   http://www.springframework.org/schema/context/spring-context-3.0.xsd"> 
<bean id="helloService" class="com.test.service.impl.HelloServiceImpl"></bean>

<import resource="spring-cxf.xml" />

</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"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"> 
<jaxws:endpoint implementor="#helloService" address="/hello"/>

</beans>

注意：<jaxws:endpoint>的属性implementor引用的是bean的id，但必须以“#”开头，这是cxf特有的写法。

同样，在<jaxws:server serviceClass="#helloService">也是可以的。

在配置集成文件，应该注意以下几点：
1、引入jaxws命名空间

2、两种部署方式:

(1)、<jaxws:endpoint ...>方式，相当于：

Endpoint.publish("http://localhost:8080/helloService", new HelloServiceImpl());

属性implementor表示需要部署的web服务实现类，address表示访问地址，一个标示，表示访问的是具体的哪个Web服务。

(2)、

<jaxws:server  serviceClass="com.test.service.impl.HelloServiceImpl" address="/hello" ></jaxws:server>

相当于：JaxWsServerFactoryBean factory = new JaxWsServerFactoryBean();

其中serviceClass属性用来设置Web服务实现类，address用来设置访问地址，与(1)一样。

(3)、配置拦截器

<jaxws:endpoint id="helloService" implementor="#helloServiceImpl" address="/soap/hello">
<jaxws:inInterceptors>
<bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean>
</jaxws:inInterceptors>
<jaxws:outInterceptors>
<bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"></bean>
</jaxws:outInterceptors>
</jaxws:endpoint>

web配置文件：web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

<!-- Spring -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- CXF -->
<servlet>
<servlet-name>cxf</servlet-name>
<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>cxf</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>
</web-app>

这个没什么好说的，（1）配置Spring监听器以及spring配置文件，（2）配置CXFServlet。

将以上项目部署到tomcat中，启动tomcat，并访问：
http://localhost:8080/springCxfWebservice（项目名称或者你设置的对外部署名称）/services，显示如下界面：


显示WSDL文件：http://localhost:8080/springCxfWebservice/services/hello?wsdl,如下：

<wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://impl.service.test.com/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:ns2="http://schemas.xmlsoap.org/soap/http" xmlns:ns1="http://inter.service.test.com/" name="HelloServiceImplService" targetNamespace="http://impl.service.test.com/">
<wsdl:import location="http://localhost:8080/springCxfWebservice/services/hello?wsdl=HelloService.wsdl" namespace="http://inter.service.test.com/"></wsdl:import>
<wsdl:binding name="HelloServiceImplServiceSoapBinding" type="ns1:HelloService">
<soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="sayHello">
<soap:operation soapAction="" style="document"/>
<wsdl:input name="sayHello">
<soap:body use="literal"/>
</wsdl:input>
<wsdl:output name="sayHelloResponse">
<soap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="HelloServiceImplService">
<wsdl:port binding="tns:HelloServiceImplServiceSoapBinding" name="HelloServiceImplPort">
<soap:address location="http://localhost:8080/springCxfWebservice/services/hello"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>

客户端：

配置文件：spring-client.xml,不能够放在WEB-INF下

<?xml version="1.0" encoding="UTF-8"?>
<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-4.0.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"> 
<jaxws:client id="helloService"
serviceClass="com.test.service.inter.HelloService"
address="http://localhost:8080/springCxfWebservice/services/hello"/>

</beans>

客户端代码：

package com.test.client;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.test.service.inter.HelloService;

public class Client {

public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext("spring-client.xml");
HelloService helloService = context.getBean("helloService", HelloService.class);
String result = helloService.sayHello("cxf");
System.out.println(result);
}
}

执行结果：

您好：cxf
