一.JDK自带的 JAX-WS 方式开发WebService服务
1.服务端开发与发布
编写接口@WebServicepublic interface JaxWsDemo { String helloJaxWS(String userName);}@WebServicepublic class JaxWsDemoImpl implements JaxWsDemo { @WebMethod @WebResult(name = "jaxWSResult") @Override public String helloJaxWS(@WebParam(name = "userName")String userName) { return "hello," + userName + "This is a Web Service developed through JAX-WS"; }}public class JAXWSPublishMain { public static void main(String[] args) { String address = "http://127.0.0.1:8888/JaxWSTest"; Endpoint.publish(address, new JaxWsDemoImpl()); System.out.println("WebService 服务已发布！"); }}打开浏览器输入http://127.0.0.1:8888/JaxWSTest?wsdl访问，如下面内容

生成客户端源码切换到要生成客户端源码的路径下，如下：
cd F:\SpringBootProjects\webServiceDemo\jwsDemo\src\main\java\demoOne\client>根据wsdl文档地址生成源码信息：
F:\SpringBootProjects\webServiceDemo\jwsDemo\src\main\java\demoOne\client>wsimport -d F:\SpringBootProjects\webServiceDemo\jwsDemo\src\main\java\demoOne\client-keep -verbose http://127.0.0.1:8888/JaxWSTest?wsdl参数说明：
wsimport : 导入命令,如果使用cxf就换成 wsdl2java 命令 -d [源码位置] : 指定要生成的源码的目录，不指定则默认在哪个目录打开的cmd窗口，就生在那个目录下-keep : 是否生成*.java的源文件，写了此参数则直接生成*.java与*.class文件，不写此参数则只有*.class文件 -verbose : 显示文件生成过程中的详细信息-p [包名]: 指定要生成在哪个包下，不指定生成时取默认package demoOne.client;import demoone.JaxWsDemoImplService;/** * Created by IntelliJ IDEA. * User: jinshengyuan * Date: 2019-03-13 * Time: 10:34 * description: 客户端测试 **/public class ClientTest { public static void main(String[] args) { demoone.JaxWsDemoImplService implService = new JaxWsDemoImplService(); demoone.JaxWsDemoImpl jaxWsDemo = (demoone.JaxWsDemoImpl)implService.getJaxWsDemoImplPort(); String aa = jaxWsDemo.helloJaxWS("Tom "); System.out.println("调用WebService执行结果："+aa); }}执行结果：
调用WebService执行结果：hello,Tom This is a Web Service developed through JAX-WS二.Axis1.4调用.Net返回值为DataSet类型的WebService接口
1.相关说明
JDK版本：1.8.0_172axis版本：Axis1.42. Axis1.4客户端WebService服务
1.Axis1.4下载
官网：http://axis.apache.org/axis/下载后是一个压缩文件：axis-bin_1.4.zip非maven环境，则导入axis-bin_1.4.zip包下的lib目录下的所有jar包，如下图：
4.maven环境的话，在pom.xml中添加下面的依赖即可
<!--Axis1.4 及其依赖 begin--> <!-- https://mvnrepository.com/artifact/org.apache.axis/axis --> <dependency> <groupId>org.apache.axis</groupId> <artifactId>axis</artifactId> <version>1.4</version> </dependency> <!-- https://mvnrepository.com/artifact/jaxrpc/jaxrpc --> <!-- https://mvnrepository.com/artifact/axis/axis-jaxrpc --> <dependency> <groupId>axis</groupId> <artifactId>axis-jaxrpc</artifactId> <version>1.4</version> </dependency> <!-- https://mvnrepository.com/artifact/axis/axis-ant --> <dependency> <groupId>axis</groupId> <artifactId>axis-ant</artifactId> <version>1.4</version> </dependency> <!-- https://mvnrepository.com/artifact/axis/axis-saaj --> <dependency> <groupId>axis</groupId> <artifactId>axis-saaj</artifactId> <version>1.4</version> </dependency> <!-- https://mvnrepository.com/artifact/wsdl4j/wsdl4j --> <dependency> <groupId>wsdl4j</groupId> <artifactId>wsdl4j</artifactId> <version>1.6.3</version> </dependency> <!-- https://mvnrepository.com/artifact/commons-discovery/commons-discovery --> <dependency> <groupId>commons-discovery</groupId> <artifactId>commons-discovery</artifactId> <version>0.5</version> </dependency> <!--Axis1.4 及其依赖 end--><!-- 引入dom4j 解析数据时用--> <!-- https://mvnrepository.com/artifact/org.dom4j/dom4j --> <dependency> <groupId>org.dom4j</groupId> <artifactId>dom4j</artifactId> <version>2.1.1</version> </dependency>2.WebService服务接口地址及方法
地址：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx调用的方法：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx/getSupportDataSet
3.编写调用WebService服务的方法及数据解析
编写调用WebService服务的客户端java类,并打印结果，类名为：Axis1_Clientpackage com.yuan;import org.apache.axis.client.Call;import org.apache.axis.client.Service;import org.apache.axis.encoding.XMLType;import org.apache.axis.message.MessageElement;import org.apache.axis.types.Schema;import org.dom4j.Document;import org.dom4j.DocumentException;import org.dom4j.DocumentHelper;import org.dom4j.Element;import org.junit.Test;import javax.xml.namespace.QName;import java.net.URL;import java.util.Iterator;import java.util.List;/** * Created by IntelliJ IDEA. * User: jinshengyuan * Date: 2019-01-15 * Time: 15:13 * description: **/public class Axis1_Client { /** * 使用dom4j解析数据 */ @Test public void axisWSInvoke(){ String dataSetDataStr = axisInvokeNetDataSetData(); //System.out.println(dataSetDataStr); if(dataSetDataStr != null){ try { Document doc = DocumentHelper.parseText(dataSetDataStr);// 将字符串转为XML Element root = doc.getRootElement();// 获取根节点 Iterator iterator = root.elementIterator("Zone");//迭代节点 String id,zone; while(iterator.hasNext()){ Element element = (Element) iterator.next(); id = element.elementTextTrim("ID");//取出Zone节点下的ID元素的值 zone = element.elementTextTrim("Zone");//取出Zone节点下的Zone元素的值 System.out.println("Id:"+id+"=============================Zone:"+zone); } } catch (DocumentException e) { e.printStackTrace(); } } } /** * 调用.Net写的返回值为DataSet类型的WebService服务 * @return */ public String axisInvokeNetDataSetData(){ Service service = new Service(); String strXml = null; Call call = null; try { call = (Call) service.createCall(); call.setTargetEndpointAddress(new URL("http://www.webxml.com.cn/WebServices/WeatherWebService.asmx"));//WSURL，注意不要带?wsdl //调用方法方法前设置相关参数 call.setOperationName(new QName("http://WebXml.com.cn/", "getSupportDataSet")); call.setReturnType(XMLType.XSD_SCHEMA);//返回类型，这里一定要传入 XMLType.XSD_SCHEMA 类型 call.setUseSOAPAction(true); call.setSOAPActionURI("http://WebXml.com.cn/getSupportDataSet");//soapAction Object obj = call.invoke((Object[]) null); Schema schema = (Schema) obj; MessageElement[] messageElements = schema.get_any(); List messageHead = messageElements[0].getChildren();//消息头,DataSet对象 List messageBody = messageElements[1].getChildren();//消息体信息,DataSet对象,最终需要解析的数据 if (messageBody.size() > 0) { String head = messageHead.get(0).toString();//消息头,DataSet对象 String diffgr = messageBody.get(0).toString();//消息体的字符串形式 strXml = diffgr; System.out.println("head:\n"+head); System.out.println("diffgr:\n" + diffgr); } } catch (Exception e) { e.printStackTrace(); } return strXml; }}Id:1=============================Zone:直辖市Id:2=============================Zone:特别行政区Id:3=============================Zone:黑龙江Id:4=============================Zone:吉林Id:5=============================Zone:辽宁Id:6=============================Zone:内蒙古Id:7=============================Zone:河北Id:8=============================Zone:河南Id:9=============================Zone:山东Id:10=============================Zone:山西Id:11=============================Zone:江苏Id:12=============================Zone:安徽Id:13=============================Zone:陕西Id:14=============================Zone:宁夏Id:15=============================Zone:甘肃Id:16=============================Zone:青海Id:17=============================Zone:湖北Id:18=============================Zone:湖南Id:19=============================Zone:浙江Id:20=============================Zone:江西Id:21=============================Zone:福建Id:22=============================Zone:贵州Id:23=============================Zone:四川Id:24=============================Zone:广东Id:25=============================Zone:广西Id:26=============================Zone:云南Id:27=============================Zone:海南Id:28=============================Zone:新疆Id:29=============================Zone:西藏Id:30=============================Zone:台湾Id:31=============================Zone:亚洲Id:32=============================Zone:欧洲Id:33=============================Zone:非洲Id:34=============================Zone:北美洲Id:35=============================Zone:南美洲Id:36=============================Zone:大洋洲三. CXF 开发WebService接口
1. jax-ws实现
场景：CXF结合Spring实现发布与调用简单的WebService
导入包 pom.xml引入cxf的依赖即可 开发java接口与实现类代码 编写接口package com.ssm.webservice;import javax.jws.WebMethod;import javax.jws.WebParam;import javax.jws.WebResult;import javax.jws.WebService;/** * Created by IntelliJ IDEA. * User: jinshengyuan * Date: 2018-11-09 * Time: 9:04 * description: **/@WebServicepublic interface Hello { @WebMethod @WebResult(name = "result") String sayHello(@WebParam(name = "name") String name);}package com.ssm.webservice.impl;import com.ssm.dao.sysManagement.ComLogMapper;import com.ssm.model.ComLog;import com.ssm.service.sysManagement.ComLogService;import com.ssm.utils.CommonsUtil;import com.ssm.webservice.Hello;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;import java.text.SimpleDateFormat;import java.util.Date;/** * Created by IntelliJ IDEA. * User: jinshengyuan * Date: 2018-11-09 * Time: 9:06 * description: **/public class HelloImpl implements Hello { //这里跟controller中调用Service一样，使用@Autowired注解自动注入service @Autowired ComLogService comLogService; @Override public String sayHello(String name) { //从数据库中获取当前系统日期 Date date = comLogService.getCurrentDatetime(); String currentDateTime = null; if(date != null){ SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); currentDateTime = dateFormat.format(date); System.out.println("系统日期："+currentDateTime); } return "hello," + name + ",当前时间为："+currentDateTime; }} <!-- 引入CXF配置文件，低版本(3.0以下)还需引入其他两个文件 --> <import resource="classpath:META-INF/cxf/cxf.xml" /> <!-- 配置方式1 注意：serviceClass为接口类并非接口的实现类 --> <jaxws:server serviceClass="com.ssm.webservice.Hello" address="/webServiceTestA"></jaxws:server> <!--访问地址：http://localhost:8080/ssm/webService/webServiceTestA?wsdl--> <!-- 配置方式2 注意：implementor为接口的具体实现类,与springmvc整合时，推荐使用这种方式，如果使用配置方式1，则会在访问时，提示如下错误： org.apache.cxf.interceptor.Fault: Could not instantiate service class com.ssm.webservice.Hello because it is an interface. --> <jaxws:endpoint implementor="com.ssm.webservice.impl.HelloImpl" address="/webServiceTest"></jaxws:endpoint> <!--访问地址：http://localhost:8080/ssm/webService/webServiceTest?wsdl--> <!-- cxf服务启动servlet --> <servlet> <servlet-name>CXFServlet</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <!--工程名(ssm)后面紧跟的 url--> <url-pattern>/webService/*</url-pattern> </servlet-mapping>2. CXF-RESTFul服务实现
JAX-RS概述JAX-RS是Java提供用于开发RESTful Web服务基于注解(annotation)的API。JAX-RS旨在定义一个统一的规范，使得Java程序员可以使用一套固定的接口来开发REST应用，避免了依赖第三方框架。同时JAX-RS使用POJO编程模型和基于注解的配置并集成JAXB，可以有效缩短REST应用的开发周期。JAX-RS只定义RESTful API，具体实现由第三方提供，如Jersey、Apache CXF等。
JAX-RS包含近五十多个接口、注解和抽象类：
javax.ws.rs包含用于创建RESTful服务资源的高层次（High-level）接 口和注解。javax.ws.rs.core包含用于创建RESTful服务资源的低层次（Low-level）接口和注解。javax.ws.rs.ext包含用于扩展JAX-RS API支持类型的APIs。JAX-RS常用注解：
@Path：标注资源类或方法的相对路径。@GET、@PUT、@POST、@DELETE：标注方法的HTTP请求类型。@Produces：标注返回的MIME媒体类型。@Consumes：标注可接受请求的MIME媒体类型。@PathParam、@QueryParam、@HeaderParam、@CookieParam、@MatrixParam、@FormParam：标注方法的参数来自于HTTP请求的位置。@PathParam来自于URL的路径，@QueryParam来自于URL的查询参数，@HeaderParam来自于HTTP请求的头信息，@CookieParam来自于HTTP请求的Cookie。
