使用CXF搭建WebServices服务端

1 使用Maven创建Java Web工程，引入cxf和spring，pom.xml如下

    4.0.0
    com.liubo
    test-cxf
    0.0.1-SNAPSHOT
    war

    
        UTF-8
    

    
        
            org.apache.cxf
            cxf-rt-frontend-jaxws
            2.7.3
        
        
            org.springframework
            spring-web
            3.1.2.RELEASE
        
        
            javax.servlet
            servlet-api
            2.5
            provided
        
        
            javax.servlet.jsp
            jsp-api
            2.1
            provided
        
    

    
        
            
                org.apache.maven.plugins
                maven-compiler-plugin
                2.3.2
                
                    1.6
                    1.6
                    UTF-8
                
            
            
                org.apache.maven.plugins
                maven-surefire-plugin
                2.7.2
                
                    once
                    -Dfile.encoding=UTF-8
                    
                        
                            net.sourceforge.cobertura.datafile
                            target/cobertura/cobertura.ser
                        
                    
                
            
        
    

2 在web.xml中配置applicationContext.xml和cxf servlet

    Archetype Created Web Application
        
            contextConfigLocation
            classpath:applicationContext.xml
        
    
        org.springframework.web.context.ContextLoaderListener
    

    
        CXFServlet
        CXF Servlet
        
            org.apache.cxf.transport.servlet.CXFServlet
        
        1
    

    
        CXFServlet
        /*
    
    
        index.jsp
    

3 创建要提供服务接口和实现

接口类

package com.liubo.test.cxf.service;

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

@WebService
public interface HelloWebService {

    String sayHello(@WebParam(name = "text") String text);
}

实现类

package com.liubo.test.cxf.serviceimpl;

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

import com.liubo.test.cxf.service.HelloWebService;

@WebService(serviceName = "HelloWS")
public class HelloWebServiceImpl implements HelloWebService {

    public String sayHello(@WebParam(name = "test") String text) {
        System.out.println("sayHello method called");
        return "hello " + text + ", welcome to the real world";
    }

}

4 配置spring文件applicationContext.xml

注意引入xmlns:jaxws和cxf.xml，

xmlns:jaxws="http://cxf.apache.org/jaxws"
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd

然后添加要提供的接口信息jaxws:endpoint id="HelloWorld"

applicationContext.xml全文如下

5 配置完成后，部署到tomcat，启动访问http://localhost:8080/test-cxf 即可看到服务已成功发布。

客户端实现见下文：使用cxf-codegen-plugin实现WebServices客户端
