配置步骤

开发基于CXF的 RESTful WebService1.创建Web项目并导入CXF的jar2.在Web.xml中配置 CXFServlet    
             
      
       cxf
              
      
       org.apache.cxf.transport.servlet.CXFServlet
          
         
             
      
       cxf
              
      
       /ws/*
          
     3.创建实体类 Person    @XmlRootElement(name = "person")    public class Person implements Serializable {        private String id;        private String name;        private String description;        @XmlElement(name = "id")        public String getId() {            return id;        }        public void setId(String id) {            this.id = id;        }        @XmlElement(name = "name")        public String getName() {            return name;        }        public void setName(String name) {            this.name = name;        }        @XmlElement(name = "description")        public String getDescription() {            return description;        }        public void setDescription(String description) {            this.description = description;        }    }4.定义 PersonService 接口    //@Produces( { MediaType.APPLICATION_XML })    @Produces( { MediaType.APPLICATION_JSON })     public interface PersonService extends Serializable {        @GET        @Path("/persons")        public List
     
       getPersons();        @GET        @Path("/persons/{id}")        public Person getPerson(@PathParam("id") String id);    }5.提供实现类 PersonServiceImpl    public class PersonServiceImpl implements PersonService {        private static final long serialVersionUID = 1L;        private static Map
      
        ps = new HashMap
       
        ();        static {            Person info = new Person();            p1.setId("1");            p1.setName("zhangsan");            p1.setDescription("hello");            Person p1 = new Person();            p2.setId("2");            p2.setName("lisi");            p2.setDescription("lisi hehe");            ps.put(p1.getId(), p1);            ps.put(p2.getId(), p2);        }        @Override        public Person getPerson(String id) {            return ps.get(id);        }        @Override        public List
        
          getPersons() {            return new ArrayList(ps.values());        }    }6.提供CXF 的配置文件 cxf-servlet.xml    
             
                 
                  
                  
                  
           
            
             
            
            
             
            
            
             
            
              
         7.访问CXFServlet：http://localhost/CXF_01/ws8.通过 URLConnection 访问WebService服务：        URLConnection conn = new URL("http://localhost/CXF_01/ws/v1/persons").openConnection();        HttpURLConnection con = (HttpURLConnection) conn;        con.setRequestMethod("GET");        int code = con.getResponseCode();        System.out.println(code);        InputStream is = con.getInputStream();        int len = 0;        byte[] b = new byte[1024];        StringBuffer sb = new StringBuffer();        while((len = is.read(b)) != -1){            String s = new String(b,0,len,"UTF-8");            sb.append(s);        }        System.out.println(sb.toString());        con.disconnect();

示例配置了

配置RESTful services服务，注意概念和 soap wsdl完全不一样的

但也是开服务 webservice

Person.java

1 package cn.itcast.domain; 2  3 import java.io.Serializable; 4  5 import javax.xml.bind.annotation.XmlElement; 6 import javax.xml.bind.annotation.XmlRootElement; 　　//通过注解，在网上序列号成xml或者json方式 7 @XmlRootElement(name = "Person") 8 public class Person implements Serializable { 9     private String id;10     private String name;11     private String desc;12     @XmlElement(name="id")13     public String getId() {14         return id;15     }16     public void setId(String id) {17         this.id = id;18     }19     @XmlElement(name="name")20     public String getName() {21         return name;22     }23     public void setName(String name) {24         this.name = name;25     }26     @XmlElement(name="desc")27     public String getDesc() {28         return desc;29     }30     public void setDesc(String desc) {31         this.desc = desc;32     }33     @Override34     public String toString() {35         return "Person [desc=" + desc + ", id=" + id + ", name=" + name + "]";36     }37     38     39 }

IPersonService.java

1 package cn.itcast.restful; 2  3 import java.io.Serializable; 4 import java.util.List; 5  6 import javax.ws.rs.GET; 7 import javax.ws.rs.Path; 8 import javax.ws.rs.PathParam; 9 import javax.ws.rs.Produces;10 import javax.ws.rs.core.MediaType;11 12 import cn.itcast.domain.Person;13 //@Produces( { MediaType.APPLICATION_XML })    xml格式，以下是json格式 传14 @Produces( { MediaType.APPLICATION_JSON })15 public interface IPersonService extends Serializable {16     17     @GET18     @Path(value="/persons/{id}")19     public Person findPersonById(20             @PathParam("id")21             String id);22     23     @GET24     @Path(value="/persons")25     public List
     
       findAllPerson();26 }

PersonServiceImpl.java

1 package cn.itcast.restful; 2  3 import java.util.ArrayList; 4 import java.util.HashMap; 5 import java.util.List; 6 import java.util.Map; 7  8 import cn.itcast.domain.Person; 9 10 public class PersonServiceImpl implements IPersonService {11     private static Map
     
       ps = new HashMap
      
       ();12     static {13         for(int i=0;i<5;i++){14             Person p = new Person();15             p.setId("id" + i);16             p.setName("person" + i);17             p.setDesc("desc" + i);18             ps.put(p.getId(), p);19         }20     }21     @Override22     public List
       
         findAllPerson() {23         24         return new ArrayList
        
         (ps.values());25     }26 27     @Override28     public Person findPersonById(String id) {29         return ps.get(id);30     }31 32 }

多加入了 60-71 配置restful方式的webservice

cxf-servlet.xml
