cxf 这里介绍在web跟非web中的发布以及调用
准备条件:
1,导入cxf的相关jar包,以maven项目为例 pom的配置文件为

2,创建实体类,接口以及实现类
package pBean;
public class Reader {
private static final long serialVersionUID = 1L;
private String name;
private String password;
public Reader(){}
public Reader(String name,String password) {
this.name = name;
this.password = password;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
//Get/Set方法省略
public String toString(){
return "Name:"+name+",Password:"+password;
}
}
定义接口类
package pInterface;
import java.util.List;
import javax.jws.WebParam;
import javax.jws.WebService;
import pBean.Reader;
@WebService
public interface IReaderService {
public Reader getReader(@WebParam(name = "name") String name,@WebParam(name = "password") String password);
public List<Reader> getReaders();
}
Tip:(里的WebParam必须指定,否则调用的时候返回null)
定义实现类
package pImpl;
import java.util.ArrayList;
import java.util.List;
import javax.jws.WebParam;
import pBean.Reader;
import pInterface.IReaderService;
public class ReaderService implements IReaderService{
public Reader getReader(@WebParam(name="name") String name,@WebParam(name="password") String password) {
return new Reader(name,password);
}
public List<Reader> getReaders(){
List<Reader> readerList = new ArrayList<Reader>();
readerList.add(new Reader("shun1","123"));
readerList.add(new Reader("shun2","123"));
return readerList;
}
}
目录结构
一、在非web中发布服务并调用
1,发布服务,
执行下面的main方法,这个服务就起来了,此时在浏览器输入http://localhost:8080/readerService?wsdl就能访问服务
package pTest;
import javax.xml.ws.Endpoint;
import pImpl.ReaderService;
/**
*@author chenrd
*@date 2018-3-20 下午3:55:42
*CXF自带了一个轻量的容器服务,相当于spring自己提供了IOC容器一样。
*我们可以先用它来测试一下我们部署成功没。
*/
public class Test {
public static void main(String[] args) {
System.out.println("Server is starting...");
ReaderService readerService = new ReaderService();
Endpoint.publish("http://localhost:8080/readerService",readerService);
System.out.println("Server is started...");
}
}
2,调用服务
package pTest;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import pBean.Reader;
import pInterface.IReaderService;
/**
*@author chenrd
*@date 2018-3-20 下午4:35:14
*业务:
*部署成功后,我们就是要调用啦,
*它的调用也相当简单,跟xfire类似,取得接口,然后就可以跟本地类一样调用方法了。
*/
public class Test2 {
/**
* 这里很简单,也是取得一个工厂类,
* 然后直接设接口和地址再create就可以得取相应的接口了,
* 这里跟xfire一样,也是需要调用端先定义好接口原型,否则这些调用将无从说起。
*/
public static void main(String[] args) {
JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
factoryBean.setServiceClass(IReaderService.class);
factoryBean.setAddress("http://localhost:8080/readerService");
IReaderService readerService = (IReaderService)factoryBean.create();
Reader reader = readerService.getReader("shun","123");
System.out.println("Reader:"+reader);
}
}
二、在web中发布服务并调用
添加下面1和2的条件
1,在web.xml中添加
<!-- 这里很简单,只是指定了spring的监听器和相应的配置文件路径,并且指定了CXF的拦截方式。 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>WEB-INF/beans.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>/webservice/*</url-pattern>
</servlet-mapping>
2,spring配置文件中的配置(这里单独放到了一个文件)
<?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="readerServicce2" implementor="pImpl.ReaderService" address="/readerService2" />
</beans>
说明:
<!--
这里很简单,只是通过jaxws:endpoint定义了一个webservice,
implementor是webservice的处理类,而address是它的访问路径,跟我们前面写的readerService类似。
这时我们可以把它部署到tomcat中,通过http://localhost:8080/CXF/webservice/readerService2?wsdl可以直接访问。
有些朋友会问,为什么这次访问的URL跟前面的不一样呢。
其实前面的访问地址是我们自己定义的,而这里的webservice地址是我们在配置文件中配置好的,并且是通过web项目来部署的,
这里就需要用项目名称,而且我们在CXFServlet那里配置了url-pattern是webservice,
所以最后的URL就跟上面一致了。 -->
发布(部署你的项目到tomcat并跑起来)
调用:
package pTest;
import javax.xml.namespace.QName;
import org.apache.cxf.endpoint.Client;
import org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory;
import pBean.Reader;
/**
* @author chenrd
* @date 2018-3-21 上午11:39:31 业务:
*/
public class Test3 {
public static void main(String[] args) {
//这个是用cxf 客户端访问cxf部署的webservice服务
//千万记住,访问cxf的webservice必须加上namespace ,否则通不过
//现在又另外一个问题,传递过去的参数服务端接收不到
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
//url为调用webService的wsdl地址
Client client = dcf.createClient("http://localhost:8080/CXF/webservice/readerService2?wsdl");
//第一个参数是wsdl的命名空间
QName qname=new QName("http://pInterface/","getReader");
//namespace是命名空间,methodName是方法名
String name = "name";
String pwd = "pwd";
//paramvalue为参数值
Object[] objects = null;
Object object = null;
try {
object = client.invoke(qname,name,pwd);
} catch (Exception e) {
e.printStackTrace();
}
//调用web Service//输出调用结果
System.out.println(object);
// System.out.println(((Reader)objects[0]).toString());
}
}
