如何传输Java对象

  JavaEE 是 J2EE的一个新的名称,之所以改名,目的还是让大家清楚J2EE只是Java企业应用。下面yjbys小编为大家准备了关于如何传输Java对象的文章,欢迎阅读。

  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。
