Apache CXF实战之一 Hello World Web Service

Apache CXF实战之二 集成Sping与Web容器

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 plain copy print ?

1. package com.googlecode.garbagecan.cxfstudy.jaxws;
3. import java.util.Date;
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 plain copy print ?

1. package com.googlecode.garbagecan.cxfstudy.jaxws;
3. import javax.jws.WebMethod;
4. import javax.jws.WebParam;
5. import javax.jws.WebResult;
6. import javax.jws.WebService;
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;

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

3. 创建Web Service接口的实现类

[java] view plain copy print ?

1. package com.googlecode.garbagecan.cxfstudy.jaxws;
3. import java.util.Calendar;
5. public class CustomerServiceImpl implements CustomerService {
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 plain copy print ?

1. package com.googlecode.garbagecan.cxfstudy.jaxws;
3. import javax.xml.ws.Endpoint;
5. import org.apache.cxf.interceptor.LoggingInInterceptor;
6. import org.apache.cxf.interceptor.LoggingOutInterceptor;
7. import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
9. public class MyServer {
11. private static final String address = "http://localhost:9000/ws/jaxws/customerService";
13. public static void 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());
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 plain copy print ?

1. package com.googlecode.garbagecan.cxfstudy.jaxws;
3. import java.net.SocketTimeoutException;
5. import javax.xml.ws.WebServiceException;
7. import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;
9. public class MyClient {
10. public static void 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();
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。
