一、什么是webservice？有什么用？
webservice是一种跨平台、跨语言的一种远程调用技术。其主要用于不同系统中的相互调用。
二、webservice的技术特点
1、XML：XML是webservice传递信息的载体。
2、SOAP：通过HTTP协议发送请求和接收结果时，发送的请求内容和结果内容都采用XML格式封装，并增加了一些特定的HTTP消息头，以说明HTTP消息的内容格式，这些特定的HTTP消息头和XML内容格式就是SOAP协议。
3、WSDL：Web Service Description Language， Web Service描述语言。它用XML的格式描述了WebService有哪些方法、参数类型、访问路径等等。
三、webservice实践
1、使用JDK来开发webservice
①服务端编写
public interface WebService { int addUp(int a, int b); int minus(int a, int b); } @javax.jws.WebService public class WebServiceImpl implements WebService { @Override public int addUp(int a, int b) { return a + b; } @Override public int minus(int a, int b) { return a - b; } } //使用监听器来进行发布，这样就可以在项目启动的时候就可以将webservice服务发布出来 @WebListener public class WebServiceListener implements ServletContextListener { public void contextInitialized(ServletContextEvent arg0) { String address = "http://127.0.0.1:9999/ws/webservice"; Endpoint.publish(address, new WebServiceImpl()); System.out.println("发布webservice服务成功。。。。。"); } @Override public void contextDestroyed(ServletContextEvent arg0) { } }
②客户端编写的两种方式：
Ⅰ、使用 wsimport -s f:\ http://127.0.0.1:9999/ws/webservice?wsdl来生成客户端代码
public class test { public static void main(String[] args) { WebServiceImplService ws = new WebServiceImplService(); WebServiceImpl wsImpl = ws.getWebServiceImplPort(); int addUp = wsImpl.addUp(1, 2); int minus = wsImpl.minus(0, 1); System.out.println(addUp); System.out.println(minus); } }
Ⅱ、使用eclispe直接新建websercice client
public class test { public static void main(String[] args) { WebServiceImplProxy proxy = new WebServiceImplProxy(); try { int addUp = proxy.addUp(1, 1); int minus = proxy.minus(2, 1); System.out.println(addUp); System.out.println(minus); } catch (RemoteException e) { e.printStackTrace(); } } }
2.使用spring 构建webservice服务端（不用webservice框架）
<!-- webservice配置 --> <bean class="org.springframework.remoting.jaxws.SimpleJaxWsServiceExporter"> <property name="baseAddress" value="http://127.0.0.1:8888/ws/"/> </bean>
@Component @WebService(serviceName="UserInfoWebService") public class UserInfoWebService { @Autowired private UserMapper userMapper; @WebMethod public User getUserInfoById(Integer id) { User user = userMapper.selectByPrimaryKey(id); return user; } }
四、spring 集成cxf
0.引入cxf相关的jar包
<dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-frontend-jaxws</artifactId> <version>3.1.8</version> </dependency> <dependency> <groupId>org.apache.cxf</groupId> <artifactId>cxf-rt-transports-http</artifactId> <version>3.1.8</version> </dependency> <dependency> <groupId>org.codehaus.woodstox</groupId> <artifactId>stax2-api</artifactId> <version>3.1.4</version> </dependency>
1.web.xml中，增加如下配置
<!-- spring 加载配置文件 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath:applicationContext.xml, classpath:application-cxf.xml </param-value> </context-param> <!-- cxf webservices --> <servlet> <description>CXF Endpoint</description> <display-name>cxf</display-name> <servlet-name>cxf</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>cxf</servlet-name> <url-pattern>/ws/*</url-pattern> </servlet-mapping>
2.新建application-cxf.xml配置文件
<?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:soap="http://cxf.apache.org/bindings/soap" xmlns:jaxws="http://cxf.apache.org/jaxws" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/bindings/soap http://cxf.apache.org/schemas/configuration/soap.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <!-- Cxf WebService 服务端示例 --> <jaxws:endpoint id="DemoWebservice" implementor="com.myproject.webservice.impl.UserInfoWebServiceImpl" address="/UserInfoWebService"/> </beans>
3.业务代码
@WebService public class UserInfoWebServiceImpl{ @Autowired private UserMapper userMapper; public String getUserInfoById(@WebParam(name="id")Integer id) { User user = userMapper.selectByPrimaryKey(id); return user.toString(); } }
这样基于cxf和spring集成的webservice就完成了，http://localhost:8080/zmyproject/ws/UserInfoWebService?wsdl
4.cxf客户端调用webservice
application-cxf.xml
<!-- Cxf WebService 客户端调用--> <jaxws:client id="arithmeticWebServiceClient" serviceClass="com.myproject.webservice.client.ArithmeticWebServiceClient" address="http://127.0.0.1:9999/ws/webservice?wsdl"></jaxws:client>
//这个要和wsdl文件中的targetNamespace以及name对应 //创建这个接口来和webservice服务对应，接口名不限，但是方法名和参数一定要和webservice @WebService(targetNamespace = "http://server.webservice/", name = "WebServiceImplService") public interface ArithmeticWebServiceClient { int addUp(int a, int b); int minus(int a, int b); }
@RequestMapping(value="/add", method=RequestMethod.POST) public Result add(HttpServletRequest request) throws ServiceException{ Result result = new Result(); Map<String, Object> params = HttpRequestUtil.initParameters(request); result.setData(userService.add(params)); return result; }
@Override public int add(Map<String, Object> params) { int a = Integer.parseInt(params.get("a").toString()); int b = Integer.parseInt(params.get("b").toString()); int result = arithmeticWebServiceClient.addUp(a, b); return result; }
