2014.1.4 cxf spring webservice

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"

        </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);

路径问题很常见，我也不是很明白，只能尝试。
