前面一篇文章中,webservice的服务端与客户端都是单独启动,但是在现实项目中,服务端单独启动太没有实际意义了,还是要整合框架启动,所以今天将记录如何整合spring框架。

(一)、web.xml中添加spring与cxf的配置
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- spring配置 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- cxf配置 --> <servlet> <servlet-name>CXFServlet</servlet-name> <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>CXFServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
(二)、新建接口文件,实现类
接口,需要添加注解webservice
@WebService public interface IHello { public String sayHi(String name); public String printName(String name); }
实现接口类,指定endpointInterface与serviceName
@WebService(endpointInterface="com.xj.service.IHello",serviceName="hello1Service") public class HelloImpl implements IHello{ @Override public String sayHi(String name) { System.out.println("hi,"+name); return "hi,"+name; } @Override public String printName(String name) { System.out.println("my name is,"+name); return "my name is,"+name; } }
(三)、配置applicationContext.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:p="http://www.springframework.org/schema/p" xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:cxf="http://cxf.apache.org/core" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.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-extension-soap.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <bean id="hello" class="com.xj.service.HelloImpl"/> <jaxws:endpoint id="testHello" implementor="#hello" address="/testHello" > </jaxws:endpoint> </beans>
需要在文件中引入这三个文件,加入相关约束
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
解释:
最关键的是jaxws:endpoint标签,这与直接启动server时,endpoint的publish作用相同,发布这个服务,implementor指定了实现类,这里用的是引用的方式,可以直接如下
<!-- <bean id="hello" class="com.xj.service.HelloImpl"/> --> <jaxws:endpoint id="testHello" implementor="com.xj.service.HelloImpl" address="/testHello" > </jaxws:endpoint>
(四)、项目部署并访问
将项目部署到tomcat中,启动无报错
访问 http://localhost/cxf/testHello?wsdl 可得到我们发布服务的wsdl,其中cxf为项目名称,testHello为我们endpoint中配置的路径
到此为止,服务端就发布完成了。
一般项目中大部分都是单独提供server端接口(即发布服务的wsdl地址),或者根据wsdl地址生成client端。
附加
(五)、启动client端
<?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:p="http://www.springframework.org/schema/p" xmlns:jaxws="http://cxf.apache.org/jaxws" xmlns:cxf="http://cxf.apache.org/core" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd"> <jaxws:client id="hello" serviceClass="com.xj.service.IHello" address="http://localhost/cxf/testHello?wsdl"> </jaxws:client> </beans>
解释:
jaxws:client 标志为服务的client端,其中address指定了需要访问的wsdl地址,id指定了一个唯一的bean标志。
public static void main(String[] args) { ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContextClient.xml"); IHello hello = (IHello) ctx.getBean("hello"); System.out.println(hello.sayHi("xiejun")); }
如上述,就可以调用服务的相关方法,但是这种调用方法需要项目中含有server端的基础类,如IHello等,显然不太现实。下一篇文章中讲继续记录 如何调用天气预报的接口,现在在那我们是没法知道server端的基础类的。
