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 WebService1.创建Web项目并导入CXF的jar2.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 PersonServiceImplpublic 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);}@Overridepublic Person getPerson(String id) {return ps.get(id);}@Overridepublic 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="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance" xmlns:jaxrs="/jaxrs"xsi:schemaLocation="/schema/beans /schema/beans/spring-beans-2.5.xsd/jaxrs /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/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

/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 { 9private String id;10private String name;11private String desc;12@XmlElement(name="id")13public String getId() {14 return id;15}16public void setId(String id) {17 this.id = id;18}19@XmlElement(name="name")20public String getName() {21 return name;22}23public void setName(String name) {24 this.name = name;25}26@XmlElement(name="desc")27public String getDesc() {28 return desc;29}30public void setDesc(String desc) {31 this.desc = desc;32}33@Override34public String toString() {35 return "Person [desc=" + desc + ", id=" + id + ", name=" + name + "]";36}373839 }

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 {1617@GET18@Path(value="/persons/{id}")19public Person findPersonById(20 @PathParam("id")21 String id);2223@GET24@Path(value="/persons")25public 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 {11private static Map<String, Person> ps = new HashMap<String, Person>();12static {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@Override22public List<Person> findAllPerson() {23 24 return new ArrayList<Person>(ps.values());25}26 27@Override28public 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

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
