用CXF将你的Java程序发布成Web Service
来源：互联网 发布：帝国cms tags伪静态 编辑：程序博客网 时间：2024/06/05 04:01
首先配置CXF环境，从apache下载cxf所需jar包。加入你的构建路径。
第二，建立一个DTO对象（用于参数是值对象类型），如下：
package bean;
import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;
/**
*@author 刘岩
*/
@XmlRootElement(name = "Customer")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(propOrder = { "name", "age" })
public class Customer {
private String name;
private int age;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
因为采用了注解形式，若不是JDK1.5，那你只能望CXF而兴叹了，还是用XFire吧。
接下来定义服务接口
package service;
import javax.jws.WebService;
import bean.Customer;
/**
*@author 刘岩
*/
@WebService(targetNamespace="iscpWebService/RemoveCooperater")
public interface CXFService {
public String sayHello(String inStr);
public void saveCust(Customer customer);
}
下面写接口实现类
package service.impl;
import javax.jws.WebService;
import bean.Customer;
import service.CXFService;
/**
*@author 刘岩
*/
@WebService(targetNamespace = "iscpWebService/RemoveCooperater", endpointInterface = "service.CXFService")
public class CXFServiceImpl implements CXFService {
public String sayHello(String inStr) {
System.out.println("服务端调用");
inStr = "<hello~~~~：>" + inStr;
return inStr;
}
public void saveCust(Customer customer) {
if (customer != null) {
customer.setName(customer.getName()+"@123");
System.out.println(customer.getName() + ":" + customer.getAge());
}
}
}
因为CXF依赖于Spring框架，所以
web.xml修改如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<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>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>/webservice/*</url-pattern>
</servlet-mapping>
</web-app>
而Spring的bean.xml内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<!-- START SNIPPET: beans -->
<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="sayHello"
implementor="service.impl.CXFServiceImpl" address="/CXFService"/>
</beans>
==================================================
好了，之后建立一个客户端项目(纯Java项目即可,无需Java Web支持),加入junit单元测试即可。
写客户端代码如下：
package test;
import junit.framework.TestCase;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
public class Client extends TestCase {
public void test01() {
JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
factoryBean.setServiceClass(CXFService.class);
factoryBean
.setAddress("http://127.0.0.1:8181/MyCXFDemo/webservice/CXFService");
CXFService client = (CXFService) factoryBean.create();
String response = client.sayHello("liuyan");
System.out.println("Response: " + response);
System.exit(0);
}
public void test02() {
JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();
factoryBean.setServiceClass(CXFService.class);
factoryBean
.setAddress("http://127.0.0.1:8181/MyCXFDemo/webservice/CXFService");
CXFService client = (CXFService) factoryBean.create();
Customer customer = new Customer();
customer.setAge(25);
customer.setName("liuyan");
client.saveCust(customer);
System.out.println("Response: " + customer.getName());
System.exit(0);
}
}
运行test01、test02成功调用服务端代码。tomcat、weblogic都测试通过。注意：有些情况是在tomcat可以正常生成wsdl，但是移植到了weblogic下面会因为jar冲突导致wsdl不能生成。
wsdl如下，用它也可以生成客户端代码：：：
