这篇文章介绍一下怎么通过CXF来发布RESTful的Web Service.

1. 首先是实体类，注意其中的@XmlRootElement注解
[java] view plain copy print ?
1. package com.googlecode.garbagecan.cxfstudy.jaxrs;
3. import java.util.Date;
5. import javax.xml.bind.annotation.XmlRootElement;
7. @XmlRootElement(name="Customer")
8. public class Customer {
9. private String id;
10. private String name;
11. private Date birthday;
12. public String getId() {
13. return id;
14. }
15. public void setId(String id) {
16. this.id = id;
17. }
18. public String getName() {
19. return name;
20. }
21. public void setName(String name) {
22. this.name = name;
23. }
24. public Date getBirthday() {
25. return birthday;
26. }
27. public void setBirthday(Date birthday) {
28. this.birthday = birthday;
29. }
30. @Override
31. public String toString() {
32. return org.apache.commons.lang.builder.ToStringBuilder.reflectionToString(this);
33. }
34. }
```
package com.googlecode.garbagecan.cxfstudy.jaxrs;

import java.util.Date;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="Customer") 
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. RESTful Web Service接口类，可以通过修改@Produces注解来声明暴露接口返回的json还是xml数据格式
[java] view plain copy print ?
1. package com.googlecode.garbagecan.cxfstudy.jaxrs;
3. import javax.ws.rs.GET;
4. import javax.ws.rs.Path;
5. import javax.ws.rs.PathParam;
6. import javax.ws.rs.Produces;
7. import javax.ws.rs.QueryParam;
9. @Path(value = "/customer")
10. @Produces("*/*")
11. //@Produces("application/xml")
12. //@Produces("application/json")
13. public interface CustomerService {
14. @GET
15. @Path(value = "/{id}/info")
16. Customer findCustomerById(@PathParam("id")String id);
18. @GET
19. @Path(value = "/search")
20. Customer findCustomerByName(@QueryParam("name")String name);
21. }
```
package com.googlecode.garbagecan.cxfstudy.jaxrs;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;

@Path(value = "/customer") 
@Produces("*/*")
//@Produces("application/xml")
//@Produces("application/json")
public interface CustomerService {
    @GET
    @Path(value = "/{id}/info")
    Customer findCustomerById(@PathParam("id")String id);
    
    @GET
    @Path(value = "/search")
    Customer findCustomerByName(@QueryParam("name")String name);
}
```
3. RESTful Web Service接口实现类
[java] view plain copy print ?
1. package com.googlecode.garbagecan.cxfstudy.jaxrs;
3. import java.util.Calendar;
5. public class CustomerServiceImpl implements CustomerService {
7. public Customer findCustomerById(String id) {
8. Customer customer = new Customer();
9. customer.setId(id);
10. customer.setName(id);
11. customer.setBirthday(Calendar.getInstance().getTime());
12. return customer;
13. }
15. public Customer findCustomerByName(String name) {
16. Customer customer = new Customer();
17. customer.setId(name);
18. customer.setName(name);
19. customer.setBirthday(Calendar.getInstance().getTime());
20. return customer;
21. }
22. }
```
package com.googlecode.garbagecan.cxfstudy.jaxrs;

import java.util.Calendar;

public class CustomerServiceImpl implements CustomerService {

    public Customer findCustomerById(String id) {
        Customer customer = new Customer();
        customer.setId(id);
        customer.setName(id);
        customer.setBirthday(Calendar.getInstance().getTime());
        return customer;
    }
    
    public Customer findCustomerByName(String name) {
        Customer customer = new Customer();
        customer.setId(name);
        customer.setName(name);
        customer.setBirthday(Calendar.getInstance().getTime());
        return customer;
    }
}
```
4. Server端代码
[java] view plain copy print ?
1. package com.googlecode.garbagecan.cxfstudy.jaxrs;
3. import org.apache.cxf.interceptor.LoggingInInterceptor;
4. import org.apache.cxf.interceptor.LoggingOutInterceptor;
5. import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;
7. public class MyServer {
8. public static void main(String[] args) throws Exception {
9. JAXRSServerFactoryBean factoryBean = new JAXRSServerFactoryBean();
10. factoryBean.getInInterceptors().add(new LoggingInInterceptor());
11. factoryBean.getOutInterceptors().add(new LoggingOutInterceptor());
12. factoryBean.setResourceClasses(CustomerServiceImpl.class);
13. factoryBean.setAddress("http://localhost:9000/ws/jaxrs");
14. factoryBean.create();
15. }
16. }
```
package com.googlecode.garbagecan.cxfstudy.jaxrs;

import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;

public class MyServer {
    public static void main(String[] args) throws Exception {
        JAXRSServerFactoryBean factoryBean = new JAXRSServerFactoryBean();
        factoryBean.getInInterceptors().add(new LoggingInInterceptor());
        factoryBean.getOutInterceptors().add(new LoggingOutInterceptor());
        factoryBean.setResourceClasses(CustomerServiceImpl.class);
        factoryBean.setAddress("http://localhost:9000/ws/jaxrs");
        factoryBean.create();
    }
}
```
5. Client端代码
[java] view plain copy print ?
1. package com.googlecode.garbagecan.cxfstudy.jaxrs;
3. import org.apache.commons.httpclient.HttpClient;
4. import org.apache.commons.httpclient.HttpStatus;
5. import org.apache.commons.httpclient.methods.GetMethod;
7. public class MyClient {
9. public static void main(String[] args) throws Exception {
10. go("http://localhost:9000/ws/jaxrs/customer/1/info");
11. go("http://localhost:9000/ws/jaxrs/customer/search?name=abc");
12. }
14. private static void go(String url) throws Exception {
15. HttpClient client = new HttpClient();
16. GetMethod method = new GetMethod(url);
17. int statusCode = client.executeMethod(method);
18. if (statusCode != HttpStatus.SC_OK) {
19. System.err.println("Method failed: " + method.getStatusLine());
20. }
21. byte[] responseBody = method.getResponseBody();
22. System.out.println(new String(responseBody));
23. }
24. }
```
package com.googlecode.garbagecan.cxfstudy.jaxrs;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.HttpStatus;
import org.apache.commons.httpclient.methods.GetMethod;

public class MyClient {

    public static void main(String[] args) throws Exception {
        go("http://localhost:9000/ws/jaxrs/customer/1/info");
        go("http://localhost:9000/ws/jaxrs/customer/search?name=abc");
    }
    
    private static void go(String url) throws Exception {
        HttpClient client = new HttpClient();
        GetMethod method = new GetMethod(url);
        int statusCode = client.executeMethod(method);
        if (statusCode != HttpStatus.SC_OK) {
            System.err.println("Method failed: " + method.getStatusLine());
        }
        byte[] responseBody = method.getResponseBody();
        System.out.println(new String(responseBody));
    }
}
```
6.测试

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