使用CXF做 webservice 简单例子
1. 借助 annotation 创建独立启动的web 服务。
准备： 新建工程 导入需要的jar 包35个，如图：
1、 首先服务点接口。
package com.longlong.twsserver;
import java.util.List;
import javax.jws.WebParam;
import javax.jws.WebService;
import com.longlong.twsserver.domain.User;
@WebService
public interface HelloWorld {
String sayHi(@WebParam(name="text")String text);
String sayHiToUser(User user);
String[] SayHiToUserList(List<User> userList);
}
2、 服务点实现。
package com.longlong.twsserver.impl;
import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;
import javax.jws.WebService;
import com.longlong.twsserver.HelloWorld;
import com.longlong.twsserver.domain.User;
@WebService(endpointInterface="com.longlong.twsserver.HelloWorld",serviceName="helloWorld")
public class HelloWorldImpl implements HelloWorld{
Map<Integer, User> users = new LinkedHashMap<Integer, User>();
public String sayHi(String text) {
return "Hello " + text;
}
public String sayHiToUser(User user) {
users.put(users.size()+1, user);
return "Hello "+ user.getName();
}
public String[] SayHiToUserList(List<User> userList) {
String[] result = new String[userList.size()];
int i=0;
for(User u:userList){
result[i] = "Hello " + u.getName();
i++;
}
return result;
}
}
3、 实体。
package com.longlong.twsserver.domain;
public class User {
private String id;
private String name;
private String description;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
}
4、 编写 WebServiceApp.java类来暴露 web服务。
package com.longlong.twsserver.server;
import javax.xml.ws.Endpoint;
import com.longlong.twsserver.impl.HelloWorldImpl;
public class WebServiceApp {
public static void main(String[] args) {
System.out.println("web service start");
HelloWorldImpl implementor = new HelloWorldImpl();
String address = "http://localhost:8080/helloWorld";
Endpoint.publish(address, implementor);
System.out.println("web service started");
}
}
5、run WebServiceApp.java 类来启动服务。 访问 http://localhost:8080/helloWorld?wsdl 查看是否显示wsdl。
6、编写客户端访问服务。
package com.longlong.twsserver.client;
import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
import com.longlong.twsserver.HelloWorld;
import com.longlong.twsserver.domain.User;
public class HelloWorldClient {
public static void main(String[] args) {
JaxWsProxyFactoryBean svr = new JaxWsProxyFactoryBean();
svr.setServiceClass(HelloWorld.class);
svr.setAddress("http://localhost:8080/helloWorld");
HelloWorld hw = (HelloWorld) svr.create();
User user = new User();
user.setName("Tony");
user.setDescription("test");
System.out.println(hw.sayHiToUser(user));
}
}
7、测试： run WebServiceApp.java 类来启动服务，然后 run HelloWorldClient.java 来访问服务。
二 集成到spring 中。
1.web.xml中加入如下内容：
<?xml version="1.0" encoding="UTF-8"?> <web-app> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <context-param> <param-name>contextConfigLocation</param-name> <param-value> WEB-INF/classes/applicationContext.xml </param-value> </context-param> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <servlet> <servlet-name>CXFServlet</servlet-name> <display-name>CXFServlet</display-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>
2.在src/目录下加入 applicationContext.xml 配置文件，内容如下：
<?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" />
<jaxws:endpoint id="helloWorld"
implementor="com.longlong.twsserver.impl.HelloWorldImpl" address="/helloWorld" />
<bean id="client" class="com.longlong.twsserver.HelloWorld"
factory-bean="clientFactory" factory-method="create" />
<bean id="clientFactory"
class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="com.longlong.twsserver.HelloWorld" />
<property name="address"
value="http://localhost:8080/TWSServer/webservice/helloWorld?wsdl" />
</bean>
</beans>
3 修改客户端。
package com.longlong.twsserver.client;
import java.util.ArrayList;
import java.util.List;
import javax.jws.WebService;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.longlong.twsserver.HelloWorld;
import com.longlong.twsserver.domain.User;
public class HelloWorldClient {
public static void main(String[] args) {
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(
"applicationContext.xml");
HelloWorld client = (HelloWorld) context.getBean("client");
User user1 = new User();
user1.setName("Tony");
user1.setDescription("test");
User user2 = new User();
user2.setName("freeman");
user2.setDescription("test");
List<User> userList = new ArrayList<User>();
userList.add(user1);
userList.add(user2);
String[] res = client.sayHiToUserList(userList);
System.out.println(res[0]);
System.out.println(res[1]);
}
}
4 发布工程 启动web服务器（我用 tomcat 6）。
5 访问 http://localhost:8080/TWSServer/webservice/helloWorld?wsdl 查看是否显示 wsdl 。
6 run run HelloWorldClient.java 来访问服务。
