CXF-based JAX-WS, JAX-RS (Restful) WebService

1. Preparation

< div style="font-family:Verdana,Geneva,Arial,Helvetica,sans-serif; font-size:13px; background-color:rgb(40,85,126)"> This is a basic CXF-based Java project< br> If you only publish JAX-WS applications, you need the following jar files:
cxf-2.4.2.jar This is the core package of CXF
xmlschema-core-2.0.jar This is the parsing of the apache schema
> neethi-3.0.1.jar package apache’s WebService strategy package
wsdl4j-1.6.2.jar I won’t use more wsdl file generation package
servlet-api.jar. .

jetty-util-7.4.5 .v20110725.jar //Because CXF uses an embedded jetty server, the following are all jetty server packages.
jetty-server-7.4.5.v20110725.jar
jetty-http-7.4.5.v20110725.jar
jetty-io-7.4.5.v20110725.jar
jetty-continuation-7.4 .5.v20110725.jar
​ < /div>

2,
If you need to use JAX-RS to publish RESTful services, add it The following jar file:
jsr311-api-1.1.1.jar / This is the new standard of WebService issued by SUN. This JSR311 package contains what annotations should be added to the class, such as @Post
If you need to return JSON-type strings need to be added again
jettison-1.3.jar //
Because cxf uses this type of JSON string to parse.
(For a jax-rs application , The first method must return a JavaBean,
cannot have no return value, and the @XmlRootElement annotation must be used on the class)
(to be continued)

CXF publishing service class:
l JaxWsServerFactoryBean
•JaxWsServerFactoryBean is used to publish a service, which can be instantiated by default construction.
• Its method is as follows:
•setServiceBean(Object) – Set a service object-*
•setAddress(String url) – bind an address and port-*
•create()-In the JavaSE environment, use jetty to publish WebService.-*

div>

•The following are optional methods:
•setServiceClass(Class cls) – Set the interface class implemented by the service object.
l JaxRsServerFactoryBean
• This type is used to publish RESTful style webService.
• The RESTful style is based on ordinary get and post requests, and can request and respond to json data.

4. Use CXF to publish a service
package cn.leaf.one;
import javax.jws.WebService;
import org.apache.cxf. jaxws.JaxWsServerFactoryBean;
/**
* Use CXF to publish a service
* WebService annotation must be added. Otherwise, no method will be exposed to the outside
* @author 王健
*/
@WebService
public class OneService {< /div>

public String sayHi(){ ///This method will be publicly announced
return “Good”;
}
public static void main(String[] args) throws Exception {
JaxWsServerFactoryBean bean //Use jaxWs to publish it
= new JaxWsServerFactoryBean();
bean. setServiceBean(new OneService());
bean.setServiceClass(OneService.class);
bean.setAddress(“http://localhost:4444/one”);

div>

bean.create(); //Internal use jetty server as support
System.err.println(“Service started successfully…”);
/ /Thread.sleep(1000*60*60);
//System.exit(0);
}
}
5. Get the above Wsdl file: http://localhost:4444/one?wsdl
6. Use wsimport or wsdl2java to generate client calling code, omitted.
7. Publish a RESTful webService
package cn.itcast.ws3;
import java.util .ArrayList;
import java.util.List;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET; < /div>

import javax.ws.rs.POST;

bean.getOutInterceptors().add( new LoggingOutInterceptor());
bean.create();// start
System.err.println(“JAX-RS started successfully…”);

Class of CXF publishing service:

l JaxWsServerFactoryBean
•JaxWsServerFactoryBean is used to publish a service, which can be instantiated by default construction.
• Its method is as follows:
•setServiceBean(Object) – Set a service object-*
•setAddress(String url) – bind an address and port-*
•create()-In the JavaSE environment, use jetty to publish WebService.-*

div>

•The following are optional methods:
•setServiceClass(Class cls) – Set the interface class implemented by the service object.
l JaxRsServerFactoryBean
• This type is used to publish RESTful style webService.
• The RESTful style is based on ordinary get and post requests, and can request and respond to json data.

l JaxWsServerFactoryBean

•JaxWsServerFactoryBean is used to publish a service, which can be instantiated by default construction.

• Its method is as follows:

•setServiceBean(Object) – set a service object-*

•setAddress(String url) – bind an address和端口- *

•create()  –  在JavaSE环境下,使用jetty发布WebService. – *

•以下是可选方法:

• setServiceClass(Class cls) – 设置服务对象实现的接口类。

l JaxRsServerFactoryBean

•此类用于发布 RESTful风格的webService.

•RESTful 风格是以普通get,post请求为标准的,并可以请求和响应json数据。

 

4、使用CXF发布一个服务

 
package cn.leaf.one;
import javax.jws.WebService;
import org.apache.cxf.jaxws.JaxWsServerFactoryBean;
/**
 * 使用CXF发布一个服务
 * 必须要添加WebService注解。否则不会对外暴露任何一个方法
 * @author 王健
 */
@WebService
public class OneService {
public String sayHi(){      ///此方法将会对外公布
return “Good”;
}
public static void main(String[] args) throws Exception {
JaxWsServerFactoryBean bean  //使用 jaxWs对其进行发布
  = new JaxWsServerFactoryBean();
bean.setServiceBean(new OneService());
bean.setServiceClass(OneService.class);
bean.setAddress(“http://localhost:4444/one”);
bean.create(); //内部使用jetty服务器做为支持
System.err.println(“服务启动成功。。 “);
//Thread.sleep(1000*60*60);
//System.exit(0);
}
}
 
5、获取上面的wsdl文件:  http://localhost:4444/one?wsdl
6、使用wsimport或是wsdl2java生成客户端调用代码,略。
7、发布一个RESTful的webService
package cn.itcast.ws3;
import java.util.ArrayList;
import java.util.List;
import javax.ws.rs.FormParam;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;
import cn.itcast.domain.User;
/**

 * JAX-RS是无状态的服务

 */
@Path(value=”/users/”) //声明uri路径
@Produces(value={MediaType.APPLICATION_XML,MediaType.APPLICATION_JSON})//声明支持的类型
public class UserServiceRS {
private List users = new ArrayList();
public UserServiceRS(){
User u = new User();
u.setAge(90);
u.setName(” 大家好”);
users.add(u);
}
/**
 * 以下代码,请在地址栏这样访问:

 */
@GET
@Path(value=”/all/”)
public List getUsers(){
System.err.println(” 调用了users方法”);
return users;
}
/**

 * http://localhost:9004/users/save/Tom/34
 * 其中:Tom为要保存的用户名,34为年龄
 * 即会保存成功
 */
@GET
@Path(value=”/save/{name}/{age}/”)
public User save(@PathParam(“name”)String name,@PathParam(“age”)String age){
User u = new User();
u.setAge(Integer.parseInt(age));
u.setName(name);
System.err.println(” 保存成功”+u);
users.add(u);
return u;
}
/**
 * 提供第二种保存方式
 * 使用@FormParam方式设置接收表单的参数
 * 通过HttpClient调用,并设置请求参数
 */
@POST
@Path(value=”/add/”)
public User add(@FormParam(“name”)String name,@FormParam(“age”)String age){
User u = new User();
u.setAge(Integer.parseInt(age));
u.setName(name);
System.err.println(” 使用POST保存成功”+u);
users.add(u);
return u;
}
public static void main(String[] args) {
JAXRSServerFactoryBean bean = // 声明JAXRS服务对象
new JAXRSServerFactoryBean();
bean.setServiceBean(new UserServiceRS());// 加载服务类
bean .setAddress(“http://localhost:9004/”);// 声明地址,注意只声明地址和端口即可
bean.getInInterceptors().add(new LoggingInInterceptor());
bean.getOutInterceptors().add(new LoggingOutInterceptor());
bean.create();// 启动
System.err.println(“JAX-RS 启动成功….”);
}
}

8、使用HttpClient调用RESTful的web服务:
package cn.itcast.ws3;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.methods.PostMethod;
/**
 * 使用URLConnection调用RESTful的服务

 * 使用urlConnection可能没有返回结果

public class UserRsClient {
UserRsClient() throws Exception{
save2();
all();
}
/**

 * @throws Exception
 */
private void all() throws Exception{

HttpClient hc = new HttpClient();
hc.getParams().setContentCharset(“UTF-8”); // 设置编码
int code = hc.executeMethod(get);
System.err.println(” 返回的状态码:”+code);
if(code==200){
String str = get.getResponseBodyAsString();
System.err.println(” 返回信息:

}
get.releaseConnection();
}
/**
 * 保存一条信息,仍然使用GET方式
 */
private void save() throws Exception{
String name = “Jack”;// 因为是get类型,所以不能包含中文
String age = “35”;
String url = “http://localhost:9004/users/save/”+name+”/”+age;
