使用apache cxf实现webservice服务

1、在idea中使用maven新建web工程并引入spring mvc，具体可以参考https://www.cnblogs.com/laoxia/p/9311442.html;

2、在工程POM文件中引入apache cxf的相关jar包：

 <dependency>
     <groupId>org.apache.cxf</groupId>
     <artifactId>apache-cxf</artifactId>
     <version>3.2.4</version>
     <type>pom</type>
 </dependency>

3、定义webservice服务的接口：

 @WebService
 public interface HelloWorld {
     @WebMethod
     String say(@WebParam(name = "inputText") String text);
 }

4、实现webservice服务：

 @WebService
 public class HelloWorldImpl implements HelloWorld {

     @Override
     public String say(@WebParam(name = "inputText") String text) {
         return "hello, My Test worlld: " + text;
     }
 }

5、定义发布webservice服务的xml文件cxfWebService.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:context="http://www.springframework.org/schema/context"
        xmlns:util="http://www.springframework.org/schema/util"
        xmlns:jaxws="http://cxf.apache.org/jaxws"
        xsi:schemaLocation="
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/util
        http://www.springframework.org/schema/util/spring-util.xsd
        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="HelloWorldBean" address="/helloworld" implementor="com.ucar.test.cxf.impl.HelloWorldImpl"/>
 </beans>

6、在web.xml文件中指定加载webservice服务配置文件和CXFServlet：

 <context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>WEB-INF/cxfWebService.xml</param-value>
 </context-param>
 ..................
 <servlet>
   <servlet-name>CXFServlet</servlet-name>
   <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
 </servlet>
 <servlet-mapping>
   <servlet-name>CXFServlet</servlet-name>
   <url-pattern>/webservice/*</url-pattern>
 </servlet-mapping>

7、将工程打包成war包并放到tomcat下运行，在浏览器中打开http://localhost:8080/test11/webservice/helloworld?wsdl  即可看到下面的界面：

此时可以编写客户端程序调用webservice服务，也可以使用wsCaller.jar来模拟调用webService服务，调用命令：java -jar wsCaller.jar；
