Apache CXF实战之三 传输Java对象

前面两篇文章介绍了怎样通过CXF来构建最基本的Web Service，并且其中暴露的接口参数和返回值都是字符串，下面来看看一个稍微复杂一点的例子。

1. 首先是一个普通的pojo对象，用来表示一个实体类

[java] view plaincopyprint?

1. package com.googlecode.garbagecan.cxfstudy.jaxws; 
2.  
3. import java.util.Date; 
4.  
5. public class Customer { 
6.     private String id; 
7.     private String name; 
8.     private Date birthday; 
9.     public String getId() { 
10.         return id; 
11.     } 
12.     public void setId(String id) { 
13.         this.id = id; 
14.     } 
15.     public String getName() { 
16.         return name; 
17.     } 
18.     public void setName(String name) { 
19.         this.name = name; 
20.     } 
21.     public Date getBirthday() { 
22.         return birthday; 
23.     } 
24.     public void setBirthday(Date birthday) { 
25.         this.birthday = birthday; 
26.     } 
27.     @Override 
28.     public String toString() { 
29.         return org.apache.commons.lang.builder.ToStringBuilder.reflectionToString(this); 
30.     } 
31. } 

package com.googlecode.garbagecan.cxfstudy.jaxws;import java.util.Date;public class Customer {    private String id;    private String name;    private Date birthday;    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 Date getBirthday() {        return birthday;    }    public void setBirthday(Date birthday) {        this.birthday = birthday;    }    @Override    public String toString() {        return org.apache.commons.lang.builder.ToStringBuilder.reflectionToString(this);    }}

2. 创建Web Service接口类

[java] view plaincopyprint?

1. package com.googlecode.garbagecan.cxfstudy.jaxws; 
2.  
3. import javax.jws.WebMethod; 
4. import javax.jws.WebParam; 
5. import javax.jws.WebResult; 
6. import javax.jws.WebService; 
7.  
8. @WebService 
9. public interface CustomerService { 
10.     @WebMethod 
11.     @WebResult Customer findCustomer(@WebParam String id); 
12. } 

package com.googlecode.garbagecan.cxfstudy.jaxws;import javax.jws.WebMethod;import javax.jws.WebParam;import javax.jws.WebResult;import javax.jws.WebService;@WebServicepublic interface CustomerService {    @WebMethod    @WebResult Customer findCustomer(@WebParam String id);}

3. 创建Web Service接口的实现类

[java] view plaincopyprint?

1. package com.googlecode.garbagecan.cxfstudy.jaxws; 
2.  
3. import java.util.Calendar; 
4.  
5. public class CustomerServiceImplimplements CustomerService { 
6.  
7.     public Customer findCustomer(String id) { 
8.         Customer customer = new Customer(); 
9.         customer.setId("customer_" + id); 
10.         customer.setName("customer_name"); 
11.         customer.setBirthday(Calendar.getInstance().getTime()); 
12.         return customer; 
13.     } 
14. } 

package com.googlecode.garbagecan.cxfstudy.jaxws;import java.util.Calendar;public class CustomerServiceImpl implements CustomerService {    public Customer findCustomer(String id) {        Customer customer = new Customer();        customer.setId("customer_" + id);        customer.setName("customer_name");        customer.setBirthday(Calendar.getInstance().getTime());        return customer;    }}

4. 下面是Server端的代码

[java] view plaincopyprint?

1. package com.googlecode.garbagecan.cxfstudy.jaxws; 
2.  
3. import javax.xml.ws.Endpoint; 
4.  
5. import org.apache.cxf.interceptor.LoggingInInterceptor; 
6. import org.apache.cxf.interceptor.LoggingOutInterceptor; 
7. import org.apache.cxf.jaxws.JaxWsServerFactoryBean; 
8.  
9. public class MyServer { 
10.      
11.     private staticfinal String address = "http://localhost:9000/ws/jaxws/customerService"; 
12.      
13.     public staticvoid main(String[] args) throws Exception { 
14.         // http://localhost:9000/ws/jaxws/customerService?wsdl 
15.         JaxWsServerFactoryBean factoryBean = new JaxWsServerFactoryBean(); 
16.         factoryBean.getInInterceptors().add(new LoggingInInterceptor()); 
17.         factoryBean.getOutInterceptors().add(new LoggingOutInterceptor()); 
18.  
19.         factoryBean.setServiceClass(CustomerServiceImpl.class); 
20.         factoryBean.setAddress(address); 
21.         factoryBean.create(); 
22.     } 
23. } 

package com.googlecode.garbagecan.cxfstudy.jaxws;import javax.xml.ws.Endpoint;import org.apache.cxf.interceptor.LoggingInInterceptor;import org.apache.cxf.interceptor.LoggingOutInterceptor;import org.apache.cxf.jaxws.JaxWsServerFactoryBean;public class MyServer {        private static final String address = "http://localhost:9000/ws/jaxws/customerService";        public static void main(String[] args) throws Exception {        // http://localhost:9000/ws/jaxws/customerService?wsdl        JaxWsServerFactoryBean factoryBean = new JaxWsServerFactoryBean();        factoryBean.getInInterceptors().add(new LoggingInInterceptor());        factoryBean.getOutInterceptors().add(new LoggingOutInterceptor());        factoryBean.setServiceClass(CustomerServiceImpl.class);        factoryBean.setAddress(address);        factoryBean.create();    }}

5. 下面是Client端的代码

[java] view plaincopyprint?

1. package com.googlecode.garbagecan.cxfstudy.jaxws; 
2.  
3. import java.net.SocketTimeoutException; 
4.  
5. import javax.xml.ws.WebServiceException; 
6.  
7. import org.apache.cxf.jaxws.JaxWsProxyFactoryBean; 
8.  
9. public class MyClient { 
10.     public staticvoid main(String[] args) throws Exception { 
11.         JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean(); 
12.         factoryBean.setAddress("http://localhost:9000/ws/jaxws/customerService"); 
13.         factoryBean.setServiceClass(CustomerService.class); 
14.         Object obj = factoryBean.create(); 
15.  
16.         CustomerService customerService = (CustomerService) obj; 
17.         try { 
18.             Customer customer = customerService.findCustomer("123"); 
19.             System.out.println("Customer: " + customer); 
20.         } catch(Exception e) { 
21.             if (e instanceof WebServiceException  
22.                     && e.getCause() instanceof SocketTimeoutException) { 
23.                 System.err.println("This is timeout exception."); 
24.             } else { 
25.                 e.printStackTrace(); 
26.             } 
27.         } 
28.     } 
29. } 

package com.googlecode.garbagecan.cxfstudy.jaxws;import java.net.SocketTimeoutException;import javax.xml.ws.WebServiceException;import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;public class MyClient {    public static void main(String[] args) throws Exception {        JaxWsProxyFactoryBean factoryBean = new JaxWsProxyFactoryBean();        factoryBean.setAddress("http://localhost:9000/ws/jaxws/customerService");        factoryBean.setServiceClass(CustomerService.class);        Object obj = factoryBean.create();        CustomerService customerService = (CustomerService) obj;        try {            Customer customer = customerService.findCustomer("123");            System.out.println("Customer: " + customer);        } catch(Exception e) {            if (e instanceof WebServiceException                     && e.getCause() instanceof SocketTimeoutException) {                System.err.println("This is timeout exception.");            } else {                e.printStackTrace();            }        }    }}

6.测试

首先运行MyServer类，然后运行MyClient类来验证Web Service。
