先创建 webservice 服务端 。 首先下载 cxf jar 包 , cxf-2.7.8 .
新建 web 项目 aa . 将下载的cxf 压缩文件解压,将lib 下的jar 全部build path 到项目下 , 如果 启动项目时 报 找不到 org.springframework.web.context.ContextLoaderListener
请将 所有的jar 包 直接拷贝到项目的lib 下。1. 新建接口 HappyNewYear,, 注意注解必须写@webservice, 其中参数@webresult 和 @webparam 在 客户端 写接口 时 ,这个方法也必须要有同样的 参数,否则报错找不到该方法. 客户端和服务端接口的包名要一致。
package com.service; import javax.jws.WebParam; import javax.jws.WebResult; import javax.jws.WebService; import com.bean.Person; @WebService public interface HappyNewYear { public @WebResult(name = "Greet") String sayHello(@WebParam(name = "friend") String person); }
2.新建实现类HappyNewYearImpl 注意注解 和 endpointInterface
package com.service; import javax.jws.WebService; import com.bean.Person; @WebService(endpointInterface = "com.service.HappyNewYear") public class HappyNewYearImpl implements HappyNewYear { public String sayHello(String person) { return "Hello, " +person; } }
3.web.xml文件配置
<?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"> <display-name>aa</display-name> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <param-value>WEB-INF/applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <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>/*</url-pattern> </servlet-mapping> </web-app>
4. applicationContext.xml 文件配置,,注意 该文件的路径 和 导入 下面的三个resource 文件。调用 地址 为greetService
<?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.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-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <jaxws:endpoint id="greetServicce" implementor="com.service.HappyNewYearImpl" address="/greetServicce" /> </beans>
访问http://localhost:8080/aa/greetServicce?wsdl 看是否出现你想要的接口 。
二 、客户端代码 。
创建 web 项目test , 同样导入上面的jar包。
CXF 提供了两种创建客户端的方式,一种是使用wsdl2java 命令生成客户端 ,另一种就是动态创建客户端 、
1. 动态调用 时 涉及参数问题:
//1. 普通的java 语言客户端
/*
* cxf 客户端动态调用 ,,基础类型 直接传入 ,复杂类型 使用这种方式传入
* */
public class Text { public static void main(String[] args) throws Exception{ /* //创建WebService客户端代理工厂 JaxWsProxyFactoryBean factory = new JaxWsProxyFactoryBean(); //注册WebService接口 factory.setServiceClass(HappyNewYear.class); //设置WebService地址 factory.setAddress("http://localhost:8082/aa/greetServicce"); HappyNewYear greetingService = (HappyNewYear)factory.create(); Person person=new Person(); person.setFirstName("张三"); person.setLastName("李四"); System.out.println("message context is:"+greetingService.sayHello(person)); */ // 注意这个Person 是 服务端 类 ,而路径对应的不是 服务端项目的路径 ,而是service,,不懂为什么。 JaxWsDynamicClientFactory clientFactory=JaxWsDynamicClientFactory.newInstance(); Client client=clientFactory.createClient("http://localhost:8082/aa/greetServicce?wsdl"); Object orderlist=Thread.currentThread().getContextClassLoader().loadClass("com.service.Person").newInstance(); Method setFirstName=orderlist.getClass().getMethod("setFirstName", String.class); setFirstName.invoke(orderlist, "张三"); Method setLastName=orderlist.getClass().getMethod("setLastName", String.class); setLastName.invoke(orderlist, "李四"); Object[] result=client.invoke("sayHello",orderlist); System.out.println(result[0]); } }
2. 第二种调用方式
1. 创建客户端接口
package com.service; import javax.jws.WebParam; import javax.jws.WebResult; import javax.jws.WebService; /* * spring cxf */ @WebService public interface HelloWorld { //String sayHello(String text); //注意把 注解也要带过来 public @WebResult(name = "Greet") String sayHello(@WebParam(name = "friend") String person); }
2. 调用
package com.service; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class HelloWorldClient { public static void main(String[] args){ //private static Logger logger=Logger.getLogger(HelloWorldClient.class); ApplicationContext context=new ClassPathXmlApplicationContext("application-client.xml"); HelloWorld client=(HelloWorld)context.getBean("client",HelloWorld.class); System.out.println(client.sayHello("张三")); } }
3 . application-client.xml配置,同样 放在src 根目录下。
<?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.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-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <!-- 主要bean和接口的路径一定要和 服务端一致 --> <bean id="client" class="com.service.HelloWorld" factory-bean="clientFactory" factory-method="create"></bean> <bean id="clientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean"> <property name="serviceClass" value="com.service.HelloWorld"></property> <property name="address" value="http://localhost:8082/aa/greetServicce"></property> </bean> </beans>
初学 ,按照网上来的。能够运行出来,原理什么的还是不懂啊,有高手推荐下学习 资料吗?
rest 风格:
可能需要手动添加jsr331-api-1.1.1.jar。。
接口:
package com.rest; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType; @Path(value="/sample") public interface RestSimple { @GET @Path("/bean/{name}") @Produces({MediaType.APPLICATION_XML,MediaType.APPLICATION_JSON}) public String getuser(@PathParam("name")String name); }
实现类,注意注解要保持一致。
package com.rest; import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType; /** * rest 风格webservice * @author Administrator * */ @Path(value="/sample") public class HelloLove implements RestSimple{ @Override @GET @Path("/bean/{name}") @Produces({MediaType.APPLICATION_XML,MediaType.APPLICATION_JSON}) public String getuser(@PathParam("name")String name) { return name; } }
配置文件,和上面的类似,
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:jaxrs="http://cxf.apache.org/jaxrs" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 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 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="person" class="com.bean.Person"></bean> <bean id="restSample" class="com.rest.HelloLove"></bean> 对应实现类 <context:component-scan base-package="com.*"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <jaxws:endpoint id="greetServicce" implementor="com.service.HappyNewYearImpl" address="/greetServicce" /> <jaxrs:server id="restServiceContainer" address="/rest"> <jaxrs:serviceBeans> <ref bean="restSample"/> </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>
访问http://localhost:8082/aa/rest?_wadl
客户端applicationContext.xml 配置文件添加
<bean id="webrest" class="org.apache.cxf.jaxrs.client.WebClient" factory-method="create"> <constructor-arg type="java.lang.String" value="http://localhost:8082/aa/rest"></constructor-arg> </bean>
测试1
package com.test; import javax.ws.rs.core.MediaType; import org.apache.cxf.jaxrs.client.WebClient; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; /* * * rest 风格测试 */ public class TestRestLove { public static void main(String[] args){ ApplicationContext ctx=new ClassPathXmlApplicationContext("application-client.xml"); WebClient client=ctx.getBean("webrest",WebClient.class); System.out.println("rest 风格"+client.path("sample/bean/章程").accept(MediaType.APPLICATION_XML).get(String.class)); } }
测试2:
配置添加
<bean id="restSampleBean" class="org.apache.cxf.jaxrs.client.JAXRSClientFactory" factory-method="create"> <constructor-arg type="java.lang.String" value="http://localhost:8000/CXFWebService/rest/" /> <constructor-arg type="java.lang.Class" value="com.hoo.service.RESTSample" /> </bean>
ApplicationContext ctx = new ClassPathXmlApplicationContext("application-client.xml");
RESTSample sample = ctx.getBean("restSampleBean", RESTSample.class);
System.out.println(sample.getBean("张三"));
客户端整合 :Spring struts
导入Spring 和struts 架包 ,和 struts2-spring-plugin.jar ,主要该架包要和struts 包对应,以防冲突
HelloAction
package com.action; import org.springframework.beans.factory.annotation.Autowired; import com.opensymphony.xwork2.ActionSupport; import com.service.HelloWorld; import com.service.Person; public class HelloAction extends ActionSupport{ /** * */ private static final long serialVersionUID = 1L; @Autowired private HelloWorld hell;//service 也需要setter/getter 方法 private String text; public String execute(){ Person p=new Person(); p.setFirstName("张三"); p.setLastName("李四"); text=hell.sayHello(p); return SUCCESS; } public String getText() { return text; } public void setText(String text) { this.text = text; } public HelloWorld getHell() { return hell; } public void setHell(HelloWorld hell) { this.hell = hell; } }
HelloWorldiml
package com.service; import javax.servlet.ServletContext; import org.apache.struts2.ServletActionContext; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import org.springframework.web.context.WebApplicationContext; import org.springframework.web.context.support.WebApplicationContextUtils; public class HelloWorldIml implements HelloWorld{ @Override public String sayHello(Person person) { /*ApplicationContext context=new ClassPathXmlApplicationContext("classpath*:applicationContext.xml"); HelloWorld client=(HelloWorld)context.getBean("client",HelloWorld.class); return client.sayHello(person);*/ //这种方式只能读指定的xml 文件, //对import 的xml文件不起作用,bean 引用也不起作用。 //所以找不到client ServletContext servletContext =ServletActionContext.getServletContext(); WebApplicationContext wac = WebApplicationContextUtils.getRequiredWebApplicationContext(servletContext); HelloWorld bean = (HelloWorld)wac.getBean("client"); return bean.sayHello(person); } }
