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

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

package com.googlecode.garbagecan.cxfstudy.jaxws;

 import javax.jws.WebMethod;
 import javax.jws.WebParam;
 import javax.jws.WebResult;
 import javax.jws.WebService;

 @WebService
 public interface CustomerService {
     @WebMethod
     @WebResult Customer findCustomer(@WebParam String id);
}

3. 创建Web Service接口的实现类

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

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

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。
