Spring+CXF restful开发WebService

一、Apache CXF介绍

Apache CXF官网地址：Apache CXF -- Index

Apache CXF下载地址：Apache CXF -- Download

二、Apache CXF服务器端使用

1、在web.xml中加上cxf的servlet

   <servlet>
        <servlet-name>CXFServletservlet-name>
        <servlet-class>
            org.apache.cxf.transport.servlet.CXFServlet  
        servlet-class>
        <load-on-startup>1load-on-startup>
    servlet>
    <servlet-mapping>
        <servlet-name>CXFServletservlet-name>
        <url-pattern>/services/*url-pattern>
    servlet-mapping>
 

2、在spring的applicationContext.xml中的配置如下：

"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:jaxws="http://cxf.apache.org/jaxws"
xmlns:jaxrs="http://cxf.apache.org/jaxrs"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://cxf.apache.org/jaxws
http://cxf.apache.org/schemas/jaxws.xsd
http://cxf.apache.org/jaxrs
http://cxf.apache.org/schemas/jaxrs.xsd">
 
<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"/>
 
<bean id="接口实现类名称" class="接口实现类" />
<jaxrs:server id="cxfServiceContainer" address="/demo">
<jaxrs:serviceBeans>
<ref bean="cxfService" />
jaxrs:serviceBeans>
<jaxrs:extensionMappings>
<entry key="json" value="application/json" />
<entry key="xml" value="application/xml" />
jaxrs:extensionMappings>
<jaxrs:languageMappings>
<entry key="en" value="en-gb"/>
jaxrs:languageMappings>
jaxrs:server>
beans>

3、写一个接口，客户端需要复制这个接口使用

@Produces({ MediaType.APPLICATION_JSON })
public interface DemoService {
    @POST
    @Path("/test")
    public String test();
}

4、写一个接口实现类

public class CxfServiceImpl implements DemoService {}

三、Apache CXF客户端使用

一、复制 DemoService接口。

二、测试接口

String url = "http://localhost:8080/CXFService/services/demo";
DemoService service1 = JAXRSClientFactory.create(url, DemoService .class);
WebClient.client(service1 ).accept(MediaType.APPLICATION_JSON); //必须写上
System.out.println(service1 .test());//测试

四、注意点

如果在服务器端，实现类里想获取来访客户端的ip可以在实现类里写

@Context
 private MessageContext messgeContext;

再获取ip的方法里写上

HttpServletRequest request = messgeContext.getHttpServletRequest();
String ip = request.getRemoteAddr();
System.out.println("client_ip:"+ip);
