CXF实现webservice （二）

spring spring-mvc cxf maven结合

1、eclipse创建maven项目

2、配置pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                </configuration>
            </plugin> 
    </plugins>
  </build>
</project>

3、创建MyWebService接口

/**
 * MyWebService.java
 *
 * This file was auto-generated from WSDL
 * by the Apache Axis 1.4 Apr 22, 2006 (06:55:48 PDT) WSDL2Java emitter.
 */

package com.it.springmvccxf;

import javax.jws.WebParam;
import javax.jws.WebService;

@WebService
public interface MyWebService {
	public int add(@WebParam(name = "firstA") int a, @WebParam(name = "firstB") int b);

	public int minus(@WebParam(name = "secondA") int a, @WebParam(name = "secondB") int b);
}

4、创建MyWebServiceImpl实现类

package com.it.springmvccxf.impl;

import javax.jws.WebService;

import com.it.springmvccxf.MyWebService;
@WebService(endpointInterface="com.it.springmvccxf.MyWebService")
public class MyWebServiceImpl implements MyWebService {

	@Override
	public int add(int a, int b) {
		System.out.println(a + "+" + b + "=" + (a + b));
		return a + b;
	}

	@Override
	public int minus(int a, int b) {
		System.out.println(a + "-" + b + "=" + (a - b));
		return a - b;
	}

}

5、配置springmvc.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:mvc="http://www.springframework.org/schema/mvc"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans.xsd 
	http://www.springframework.org/schema/mvc 
	http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd 
	http://www.springframework.org/schema/context 
	http://www.springframework.org/schema/context/spring-context-4.0.xsd"> 
	<!--配置springmvc --> <!--1.开启springmvc注解模式 --> 
	
	<mvc:annotation-driven /> <!--servlet-mapping --> 
	<!--2静态资源默认的servlet配置，（1）允许对静态资源的处理：js，gif （2）允许使用“/”做整体映射 --> 
	<!-- 容器默认的DefaultServletHandler处理 所有静态内容与无RequestMapping处理的URL -->
	<mvc:default-servlet-handler /> 
	<!--3:配置jsp 显示viewResolver -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="viewClass"
			value="org.springframework.web.servlet.view.JstlView" />
		<property name="prefix" value="/WEB-INF/views/" />
		<property name="suffix" value=".jsp" />
	</bean> <!-- 4自动扫描且只扫描@Controller -->
	<context:component-scan base-package="com.it.springmvccxf" /> 
	<!-- 定义无需Controller的url<->view直接映射 -->
	<mvc:view-controller path="/" view-name="redirect:/index" />
</beans>

6、配置applicationContext.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://cxf.apache.org/jaxws 
	http://cxf.apache.org/schemas/jaxws.xsd 
	http://www.springframework.org/schema/beans 
	http://www.springframework.org/schema/beans/spring-beans.xsd"
	default-lazy-init="true"> 
	<!-- 引入CXF Bean定义如下,早期的版本中使用 --> 
	<!--<import resource="classpath:META-INF/cxf/cxf.xml" /> 
	<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml"/>
	<import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> -->
	<!--发布webservice --> 
	<!-- WebService的实现Bean定义 --> 
	<!--web.xml配置了webservice的访问路径/server/*，那么/server/web-publish?wsdl就是该webservice的访问路径 -->
	<bean id="webserviceServer" class="com.it.springmvccxf.impl.MyWebServiceImpl" /> 
	<!-- jax-ws endpoint定义 -->
	<jaxws:endpoint id="myService" implementor="#webserviceServer"	address="/web-publish">
	</jaxws:endpoint> 
	<!--发布webservice -->
</beans>

7、配置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"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
	id="WebApp_ID" version="3.0">
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	<servlet>
		<servlet-name>springServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>springServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
	<!-- 处理中文编码 -->
	<filter>
		<filter-name>characterEncodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
		<init-param>
			<param-name>encoding</param-name>
			<param-value>UTF-8</param-value>
		</init-param>
		<init-param>
			<param-name>forceEncoding</param-name>
			<param-value>true</param-value>
		</init-param>
	</filter>
	<filter-mapping>
		<filter-name>characterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping> <!--Spring MVC是通过DispatcherServlet来加载Spring配置文件的，因此不需要在web.xml中配置ContextLoaderListener。 
		但是CXF却需要通过ContextLoaderListener来加载Spring。 -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener> <!-- 配置CXF框架的核心Servlet -->
	<servlet>
		<servlet-name>CXFServlet</servlet-name>
		<servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
		<load-on-startup>2</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>CXFServlet</servlet-name>
		<url-pattern>/server/*</url-pattern>
	</servlet-mapping>

</web-app>

8、启动项目

这里一定要注意spring-mvc与cxf使用不同的容器加载，否则会报错：
springmvc是不需要ContextLoaderListener来加载管理bean的，DispatcherServlet它有自己的容器，主要用于加载除控制器层的bean,DispatcherServlet属于子容器。
cxf需要ContextLoaderListener，cxf需要ContextLoaderListener是spring管理bean的父容器，一般用于加载非控制器层的bean。
子容器可以访问父容器中的bean，而父容器不能访问子容器。
可以把基本web请求的controller等这些bean放到spring-web.xml中，让DispatcherServlet去加载管理spring-web.xml。
把webservice相关配置到另外一个xml文件中,比如spring-webservice.xml,
让ContextLoaderListener去加载管理spring-webservice.xml和其他spring文件（）spring-mysql.xml,spring-jpa.xml等），
这样，就互不影响了。
而且：ContextLoaderListene默认会加载applicationContext.xml这个名字的文件，如果定义为spring-context.xml会报错，重命名需要context-param
此时配置tomcat启动项目后便暴露了wsd

在地址栏中输入http://localhost:8080/cxf/server/web-publish?wsdl，可以查看生成的wsdl文件如下：

<wsdl:definitions name="MyWebServiceImplService" targetNamespace="http://impl.springmvccxf.it.com/">
	<wsdl:import
		location="http://localhost:8080/cxf/server/web-publish?wsdl=MyWebService.wsdl"
		namespace="http://springmvccxf.it.com/">
	</wsdl:import>
	<wsdl:binding name="MyWebServiceImplServiceSoapBinding"
		type="ns1:MyWebService">
		<soap:binding style="document"
			transport="http://schemas.xmlsoap.org/soap/http" />
		<wsdl:operation name="add">
			<soap:operation soapAction="" style="document" />
			<wsdl:input name="add">
				<soap:body use="literal" />
			</wsdl:input>
			<wsdl:output name="addResponse">
				<soap:body use="literal" />
			</wsdl:output>
		</wsdl:operation>
		<wsdl:operation name="minus">
			<soap:operation soapAction="" style="document" />
			<wsdl:input name="minus">
				<soap:body use="literal" />
			</wsdl:input>
			<wsdl:output name="minusResponse">
				<soap:body use="literal" />
			</wsdl:output>
		</wsdl:operation>
	</wsdl:binding>
	<wsdl:service name="MyWebServiceImplService">
		<wsdl:port binding="tns:MyWebServiceImplServiceSoapBinding"
			name="MyWebServiceImplPort">
			<soap:address location="http://localhost:8080/cxf/server/web-publish" />
		</wsdl:port>
	</wsdl:service>
</wsdl:definitions>

9、调用

package com.it.springmvccxf.util;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import com.it.springmvccxf.MyWebService;

public class ClientForCXF {

	public static void main(String[] args) {
		JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
		factoryBean.setServiceClass(MyWebService.class);
		factoryBean.setAddress("http://localhost:8080/cxf/server/web-publish");
		MyWebService myWebService=(MyWebService)factoryBean.create();
		int result;
		result = myWebService.add(1, 1);
		System.out.println(result);
	}

}

10、wsdl2java生成独立客户端代码并调用

以上两种实现webservice的方法仅适用于自己有java的webservice的服务端，自己调用。而往往服务端可能由别的语言实现，或者服务端并非我们自己实现，我们没有服务端接口，我们只能获得暴漏的wsdl，并进行调用，这就需要使用wsdl2java生成该wsdl的java客户端并调用了

打开cmd（因为我们配置了环境变量，所以可以直接使用wedl2java命令）
输入

wsdl2java -encoding utf-8 -d D:\ws\wsdl2javatest http://localhost:8080/cxf/server/web-publish?wsdl

生成文件结构如下：

这时，我们变可以写客户端并调用了

package com.it.springmvccxf.impl;

import com.it.springmvccxf.MyWebService;

public class Test {

	public static void main(String[] args) {
		MyWebServiceImplService implService=new MyWebServiceImplService();
		MyWebService service=implService.getMyWebServiceImplPort();
		System.out.println(service.add(1, 1));

	}

}
