WebService 深入详解

一、webService 初步讲解

1、xml 约束 schema 写法解读

<?xml version="1.0" encoding="UTF-8" ?>
<!-- schema 约束文件 -->
<schema xmlns="http://www.w3.org/2001/XMLSchema"targetNamespace="http://www.atguigu.com/bookSchema"elementFormDefault="qualified"><!-- elementFormDefault 是否只关联跟标签 --><element name="书架"><complexType><sequence maxOccurs="unbounded"><element name="书"><complexType><sequence><element name="书名" type="string" /><element name="作者" type="string" /><element name="售价" type="string" /></sequence></complexType></element></sequence></complexType></element>
</schema><!-- schema规范中:1. 所有标签和属性都需要有schema文件来定义 ,xsd规范定义中,xmlns="http://www.w3.org/2001/XMLSchema"-w3c提供;2. 所有的schema文件都需要有targetNamespace, 3. targetNamespace的值由什么来指定?它的值是一个url(很有可能不存在),也就是在别人引用的时候要用的东西;4. 如何引入一个Schema约束?属性? : 用xmlns属性属性值: 对应的schema文件的id(targetNamespace值)-->

<?xml version="1.0" encoding="UTF-8"?>
<书架  xmlns="http://www.atguigu.com/bookSchema"xmlns:tt="http://www.w3.org/2001/XMLSchema-instance"tt:schemaLocation="http://www.atguigu.com/bookSchema book.xsd"><书><书名>JavaScript开发</书名><作者>老佟</作者><售价>28.00元</售价></书>
</书架>
<!-- schema规范中:1. 所有标签和属性都需要有schema文件来定义 2. 所有的schema文件都需要有一个id, 但在这里它叫namespace, 3. namespace的值由什么来指定?由targetNamespace属性来指定, 它的值是一个url(很有可能不存在)4. 如何引入一个Schema约束?属性? : 用xmlns属性属性值: 对应的schema文件的id(namespace值)5. 如果引入的schema不是w3c组织定义, 必须指定schema文件的位置6. schema文件的位置由什么属性来指定?属性? : schemaLocation ? schemaLocation 由xmlns:tt来指定;属性值: namespace path7. 如果引入了N个约束, 需要给n-1个取别名-->

2、Http 协议解析

客户端连上服务器后，向服务器请求某个web资源，称之为客户端向
服务器发送了一个HTTP请求。一个完整的HTTP请求包括如下内容：
请求行
若干消息头
实体内容(可能没有,post有)，如下所示：

常用请求头(浏览器发送给服务器的数据,为了告诉服务器一些情况)
Accept: text/html,image/*    我支持的数据类型
Accept-Charset: utf-8　　支持的数据的编码字符集
Accept-Encoding: gzip　支持的压缩方式
Accept-Language: en-us,zh-cn 支持的语言
Host: localhost:8888　请求的主机名
Referer: http://www.atguigu.com/index.jsp　发送请求的界面对应的url 防盗链
User-Agent: Mozilla/4.0 浏览器的相关信息
Connection: keep-Alive   请求完成后，到是断开呢还是连接着
Date: Tue, 11 Jul 2000 18:23:51 GMT　发送请求的时间
Cookie: tt=123     //后面专门讲

响应头(浏览器发送给服务器的数据,为了告诉服务器一些情况):
Location: /day05/index.jsp 告诉浏览器重新定向到指定的路径
Server:apache tomcat　使用的什么web服务器
Content-Encoding: gzip 告诉浏览器我传给你的数据用的压缩方式
Content-Length: 80 响应体的字节数
Content-Language: zh-cn 响应体数据的语言
content-type: text/html; charset=GB2312 响应体内容的类型　html/ css / image
Last-Modified: Tue, 11 Jul 2000 18:23:51 GMT 资源最后被修改的时间
Refresh: 1定时刷新
Content-Disposition: attachment; filename=aaa.zip 提示用户下载
Set-Cookie:SS=Q0=5Lb_nQ; path=/search 将cookie数据回送给ie
Expires: -1 告诉浏览器不要缓存起来　
Cache-Control: no-cache
Pragma: no-cache
Connection: close/Keep-Alive 是否保持连接
Date: Tue, 11 Jul 2000 18:23:51 GMT 响应的时间

3、webService 四大术语解读

WSDL

直译 : WebService定义语言

1. 对应一种类型的文件.wsdl

2. 定义了web service的服务器端与客户端应用交互传递请求和响应数据的格式和方式

3. 一个web service对应一个唯一的wsdl文档

SOAP：simple object access protocal

直译: 简单对象访问协议

1.是一种简单的、基于HTTP和XML的协议, 用于在WEB上交换结构化的数据

2.soap消息：请求消息和响应消息

3.http+xml片断

SEI：WebService EndPoint Interface(终端)

直译: web service的终端接口，

就是WebService服务器端用来处理请求的接口

@Webservice

@WebMethod

CXF：Celtix + XFire

一个apache的用于开发webservice服务器端和客户端的框架

二、使用JDK原生发布webService服务

1、创建数据发布接口及实现类,并创建发布程序类

package com.bjsxt.web.ws.ws;
import javax.jws.WebMethod;
import javax.jws.WebService;
/*** SEI 定义发布接口*/
@WebService
public interface HelloWs {@WebMethodpublic String sayHello(String name);
}

package com.bjsxt.web.ws.ws;import javax.jws.WebService;
/***  SEI 定义发布接口实现 */
@WebService
public class HelloWsImpl implements HelloWs {@Overridepublic String sayHello(String name) {System.out.println("调用 webService 成功 ...");return "welComn user :"+name;}
}

package com.bjsxt.web.ws.ws;import javax.xml.ws.Endpoint;public class StartWebService {
public static void main(String[] args) {String address = "http://localhost:8088/webService/HelloWs";Endpoint.publish(address, new HelloWsImpl());//发布webService服务System.out.println("发布webService成功...");
}}

2、使用JDK提供的 wsimport 实现创建client

① cmd →进入目录(存放生成文件的目录,该项目中使用了工作空间目录直接生成在了编译器中) D:\Workspaces\MyEclipse 8.6\webService\src\com\bjsxt\web\ws\client>wsimport -keephttp://localhost:8088/webService/HelloWs?wsdl

② 创建测试类

package com.bjsxt.web.ws.client;public class WebServiceTest {public static void main(String[] args) {HelloWsImplService implService = new HelloWsImplService();HelloWsImpl impl = implService.getHelloWsImplPort();System.out.println(impl.sayHello("admin"));}
}

3、将上述从网络读取wsdl改为本地读取

① 将MyEclipse中的tcp/ip设置为监听

② 将请求到的网络中的wsdl文件中的内容复制在本地新建的一个wsdl文件中(注意改掉最后一行的端口)

③ 将上面一点钟的URL改为本地路径即可获得java类

三、使用公共天气预报(.net提供的webService)

1、Google”免费WebService”, 找到提供天气预报Webservice的网络地址 –http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx.wsdl

2、在MyEclipse中新建weather.wsdl,将网络中的信息复制进去

3、问题存在：

说明: 直接生成客户端代码会抛异常, 无法生成客户端代码, 解决办法:

1. 将对应的wsdl文档保存到本地

2. 修改wsdl文档的部分内容:

将 <s:element ref="s:schema" /><s:any /> 替换成 <s:any minOccurs="2" maxOccurs="2"/>

备注: 这个是Java调用net的webservice都有的问题

4、使用JDK提供的wsimport生成客户端

四、支持多数据类型的入参(包括对象)

1、JDK自带webService开发中不支持多数据类型的开发,首先加入cxf的支持包：

下载地址：http://download.csdn.net/detail/u014201191/8661707

2、源码程序解析(没什么区别)

package com.atguigu.day01_ws.ws2;import java.util.List;
import java.util.Map;
import javax.jws.WebMethod;
import javax.jws.WebService;import com.atguigu.day01_ws.bean.Student;@WebService
public interface DataTypeWS {@WebMethodpublic boolean addStudent(Student s);@WebMethodpublic Student getStudentById(int id);@WebMethodpublic List<Student> getStudentsByPrice(float price);@WebMethodpublic Map<Integer, Student> getAllStudentsMap();
}

package com.atguigu.day01_ws.ws2;import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;import javax.jws.WebService;import com.atguigu.day01_ws.bean.Student;@WebService
public class DataTypeWSImpl implements DataTypeWS {@Overridepublic boolean addStudent(Student s) {System.out.println("server addStudent() "+s);return true;}@Overridepublic Student getStudentById(int id) {System.out.println("server getStudentById() "+id);return new Student(id, "CAT", 1000);}@Overridepublic List<Student> getStudentsByPrice(float price) {System.out.println("server getStudentsByPrice() "+price);List<Student> list = new ArrayList<Student>();list.add(new Student(1, "TOM1", price+1));list.add(new Student(2, "TOM2", price+2));list.add(new Student(3, "TOM3", price+3));return list;}@Overridepublic Map<Integer, Student> getAllStudentsMap() {System.out.println("server getAllStudentsMap() ");Map<Integer, Student> map = new HashMap<Integer, Student>();map.put(1, new Student(1, "JACK1", 2345));map.put(3, new Student(3, "JACK3", 2375));map.put(2, new Student(2, "JACK2", 12345));return map;}
}

package com.atguigu.day01_ws.bean;public class Student {private int id;private String name;private float price;public Student(int id, String name, float price) {super();this.id = id;this.name = name;this.price = price;}public Student() {super();}public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public float getPrice() {return price;}public void setPrice(float price) {this.price = price;}@Overridepublic String toString() {return "Student [id=" + id + ", name=" + name + ", price=" + price+ "]";}}

package com.bjsxt.web.ws.ws.type;import javax.xml.ws.Endpoint;import com.atguigu.day01_ws.ws2.DataTypeWSImpl;public class StartWebService {
public static void main(String[] args) {String address = "http://localhost:8888/day01_ws/datatypews";Endpoint.publish(address , new DataTypeWSImpl());System.out.println("发布成功");}
}

五、CXF拦截器

1、日志拦截器

在JDK中没有拦截器,导入cxf包后,引用拦截器,就和第四大点中的一样,导入cxf包后,更好的配合JDK开发.

拦截器分类
1.按所处的位置分：服务器端拦截器，客户端拦截器
2.按消息的方向分：入拦截器，出拦截器
3.按定义者分：系统拦截器，自定义拦截器

拦截器API
Interceptor(拦截器接口)
AbstractPhaseInterceptor(自定义拦截器从此继承)
LoggingInInterceptor(系统日志入拦截器类)
LoggingOutInterceptor(系统日志出拦截器类)

服务端拦截器:接口发布程序都一样,在终端启动的时候加入拦截器

package com.bjsxt.web.ws.ws;import java.util.List;import javax.xml.ws.Endpoint;import org.apache.cxf.interceptor.Interceptor;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws.EndpointImpl;
import org.apache.cxf.message.Message;public class StartWebService2 {
public static void main(String[] args) {String address = "http://localhost:8088/webService/HelloWs";Endpoint endpoint = Endpoint.publish(address, new HelloWsImpl());//发布webService服务System.out.println(endpoint);EndpointImpl endpointImpl  = (EndpointImpl) endpoint;//服务端的日志入拦截器List<Interceptor<? extends Message>> inInterceptors = endpointImpl.getInInterceptors();inInterceptors.add(new LoggingInInterceptor());//服务端的日志出拦截器List<Interceptor<? extends Message>> outInterceptors = endpointImpl.getOutInterceptors();outInterceptors.add(new LoggingOutInterceptor());System.out.println("发布webService成功...");
}}

客户端拦截器:注意要在请求前加入拦截器

package com.bjsxt.web.ws.ws;
import java.util.List;import org.apache.cxf.frontend.ClientProxy;
import org.apache.cxf.interceptor.Interceptor;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.message.Message;
public class Client {
public static void main(String[] args) {HelloWsImplService implService = new HelloWsImplService();HelloWsImpl impl = implService.getHelloWsImplPort();//发送请求的客户端对象org.apache.cxf.endpoint.Client client = ClientProxy.getClient(impl);//客户端的日志出拦截器List<Interceptor<? extends Message>> outInterceptors = client.getOutInterceptors();outInterceptors.add(new LoggingOutInterceptor());//客户端的日志入拦截器List<Interceptor<? extends Message>> inInterceptors = client.getInInterceptors();inInterceptors.add(new LoggingInInterceptor());String result = impl.sayHello("BOB");System.out.println("client "+result);
}
}

2、使用拦截器进行用户名密码校验

服务端启动器以及拦截器(前面的接口发布不变)

package com.atguigu.day01_ws.ws.server;import java.util.List;import javax.xml.ws.Endpoint;import org.apache.cxf.interceptor.Interceptor;
import org.apache.cxf.interceptor.LoggingInInterceptor;
import org.apache.cxf.interceptor.LoggingOutInterceptor;
import org.apache.cxf.jaxws22.EndpointImpl;
import org.apache.cxf.message.Message;import com.atguigu.day01_ws.interceptor.CheckUserInterceptor;
import com.atguigu.day01_ws.ws.HelloWSImpl;public class ServerTest4 {public static void main(String[] args) {String address = "http://192.168.10.165:8888/day01_ws/datatypews";Endpoint endpoint = Endpoint.publish(address , new HelloWSImpl());System.out.println(endpoint);EndpointImpl endpointImpl  = (EndpointImpl) endpoint;//服务端的入拦截器List<Interceptor<? extends Message>> inInterceptors = endpointImpl.getInInterceptors();inInterceptors.add(new CheckUserInterceptor());System.out.println("发布webservice成功!");}
}

package com.atguigu.day01_ws.interceptor;import javax.xml.namespace.QName;import org.apache.cxf.binding.soap.SoapMessage;
import org.apache.cxf.headers.Header;
import org.apache.cxf.interceptor.Fault;
import org.apache.cxf.phase.AbstractPhaseInterceptor;
import org.apache.cxf.phase.Phase;
import org.w3c.dom.Element;
/*** 查检用户的拦截器* @author xfzhang**/
public class CheckUserInterceptor extends AbstractPhaseInterceptor<SoapMessage> {public CheckUserInterceptor() {super(Phase.PRE_PROTOCOL);//在解析时候拦截}/*<Envelope><head><atguigu><name>xfzhang</name><password>123456</password></atguigu><atguigu2><name>xfzhang</name><password>123456</password></atguigu2><head><Body><sayHello><arg0>BOB</arg0><sayHello></Body></Envelope>*/@Overridepublic void handleMessage(SoapMessage message) throws Fault {Header header = message.getHeader(new QName("atguigu"));if(header!=null) {Element atguiguEle = (Element) header.getObject();String name = atguiguEle.getElementsByTagName("name").item(0).getTextContent();String password = atguiguEle.getElementsByTagName("password").item(0).getTextContent();if("xfzhang".equals(name) && "123456".equals(password)) {System.out.println("Server 通过拦截器....");return;}}//不能通过System.out.println("Server 没有通过拦截器....");throw new Fault(new RuntimeException("请求需要一个正确的用户名和密码!"));}}

客户端

package com.atguigu.day01_ws_cxf_client.test;import java.util.List;import org.apache.cxf.endpoint.Client;
import org.apache.cxf.frontend.ClientProxy;
import org.apache.cxf.interceptor.Interceptor;
import org.apache.cxf.message.Message;import com.atguigu.day01_ws.ws.HelloWS;
import com.atguigu.day01_ws.ws.HelloWSImplService;
import com.atguigu.day01_ws_cxf_client.interceptor.AddUserInterceptor;/** 测试自定义拦截器*/
public class ClientTest4 {public static void main(String[] args) {HelloWSImplService factory = new HelloWSImplService();HelloWS hellWS = factory.getHelloWSImplPort();//发送请求的客户端对象Client client = ClientProxy.getClient(hellWS);//客户端的自定义出拦截器List<Interceptor<? extends Message>> outInterceptors = client.getOutInterceptors();outInterceptors.add(new AddUserInterceptor("xfzhang", "1234564"));String result = hellWS.sayHello("BOB");System.out.println("client "+result);}
}

package com.atguigu.day01_ws_cxf_client.interceptor;import java.util.List;import javax.xml.namespace.QName;import org.apache.cxf.binding.soap.SoapMessage;

六、基于CXF Spring 的webService开发

描述:本次讲解中使用了Spring Cxf 框架进行开发webService,目前没有纯cxf的开发,纯cxf开发只是加入包,辅助JDK的开发(传递数据格式,拦截器)

下面的源码中包含了第七大点和第八大点的项目清单

同时生成webService客户端文件还是一样方法 wsimport -keep url

七、Ajax、jQuery、HttpUrlConnection请求webService

解析：在index.jsp这个页面中,js方法中有var data = '<soapenv:Envelope>' 这个就是我们在日志拦截器中打印得到的请求体,同样在js回调函数中,使用ajaxyq.responseXML获得响应体,直接就转换成了XML数据,获取其返回值;下面的jQuery和httpcontentservlet请求也在这个页面中包含了;

<%@ page language="java" contentType="text/html; charset=utf-8"pageEncoding="utf-8"%>
