开发基于CXF的 RESTful WebService web 项目 webservice发布

配置步骤

开发基于CXF的 RESTful WebService

1.创建Web项目并导入CXF的jar
2.在Web.xml中配置 CXFServlet
    <servlet>
        <servlet-name>cxf</servlet-name>
        <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>cxf</servlet-name>
        <url-pattern>/ws/*</url-pattern>
    </servlet-mapping>
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<Person> 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<String, Person> ps = new HashMap<String, Person>();
        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<Person> getPersons() {
            return new ArrayList(ps.values());
        }
    }
6.提供CXF 的配置文件 cxf-servlet.xml
    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
        xmlns:jaxrs="http://cxf.apache.org/jaxrs"
        xsi:schemaLocation="http://www.springframework.org/schema/beans 
                            http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
                            http://cxf.apache.org/jaxrs 
                            http://cxf.apache.org/schemas/jaxrs.xsd">
        <import resource="classpath:META-INF/cxf/cxf.xml" />
        <import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
        <bean id="personService" class="cn.itcast.cxf.PersonServiceImpl" />
        <jaxrs:server id="RestService" address="/v1">
            <jaxrs:serviceBeans>
                <ref bean="personService" />
            </jaxrs:serviceBeans>
            <jaxrs:inInterceptors>
                <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean>
            </jaxrs:inInterceptors>
            <jaxrs:outInterceptors>
                <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"></bean>
            </jaxrs:outInterceptors>
        </jaxrs:server>
    </beans>
7.访问CXFServlet：http://localhost/CXF_01/ws
8.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

http://i.cnblogs.com/EditPosts.aspx?postid=3806298 之后

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     @Override
34     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     @GET
18     @Path(value="/persons/{id}")
19     public Person findPersonById(
20             @PathParam("id")
21             String id);
22     
23     @GET
24     @Path(value="/persons")
25     public List<Person> 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<String, Person> ps = new HashMap<String, Person>();
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     @Override
22     public List<Person> findAllPerson() {
23         
24         return new ArrayList<Person>(ps.values());
25     }
26 
27     @Override
28     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

35   <welcome-file-list>
36     <welcome-file>index.jsp</welcome-file>

发布了之后 ,cxf在上面web.xml中被过滤处理

通过localhost:8080/项目/cxf +/persons(接口中的path路径) 访问到服务器

通过接口中 path的路径直接访问提供服务的方法
