本文主要是介绍Axis2与Spring集成发布,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
在现今的Web应用中经常使用spring框架来装载JavaBean。如果要想将某些在spring中装配的JavaBean发布成WebService,使用Axis2的Spring感知功能是非常容易做到的。1、首先建立一个web工程,名字叫WebService,
2、把相应的axis2的jar文件考到WEB-INF的lib下
3、 在项目的WebRoot下的目录结构要和以前用war包是的目录结构一样(否则可能就要报错了)
目录结构如图所示:
4、在src下建立package sample.service
5、建立提供服务的接口
- package sample.service;
- /**
- * 定义服务接口
- * @author 11111
- *
- */
- public interface ServiceServer {
- //定义服务方法
- public String sayHello(String name);
- }
package sample.service; /** * 定义服务接口 * @author 11111 * */
public interface ServiceServer {
//定义服务方法 public String sayHello(String name); }
实现类:
- package sample.service;
- public class ServiceServerImpl implements ServiceServer {
- public String sayHello(String name) {
- return "hello"+name;
- }
- }
package sample.service; public class ServiceServerImpl implements ServiceServer { public String sayHello(String name) { return "hello"+name; } }
6、在src下建立applicationContext.xml文件
配置如下
- <?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:aop="http://www.springframework.org/schema/aop"
- xmlns:tx="http://www.springframework.org/schema/tx"
- xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
- http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
- http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">
- <bean id="SayHelloService" class="sample.service.ServiceServerImpl">
- </bean>
- </beans>
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> <bean id="SayHelloService" class="sample.service.ServiceServerImpl">
</bean> </beans>
7、在WebRoor/WEB-INF/services/目录下建立目录sampleService(这个名字可以随便取)
然后建立在其下META-INF目录,然后再在其目录下建立services.xml
目录结构如下
services.xml的内容如下:
- <?xml version="1.0" encoding="UTF-8"?>
- <service name="HelloWorld">
- <description>web service</description>
- <parameter name="ServiceObjectSupplier">
- org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier
- </parameter>
- <parameter name="SpringBeanName">SayHelloService</parameter>
- //SpringBeanName名字是固定的不能改
- //SayHelloService是spring中注册的实现类的id(这个大家肯定很清楚了)
- <operation name="sayHello">
- <messageReceiver
- class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
- </operation>
- </service>
<?xml version="1.0" encoding="UTF-8"?> <service name="HelloWorld"> <description>web service</description> <parameter name="ServiceObjectSupplier"> org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier </parameter> <parameter name="SpringBeanName">SayHelloService</parameter>
//SpringBeanName名字是固定的不能改
//SayHelloService是spring中注册的实现类的id(这个大家肯定很清楚了) <operation name="sayHello"> <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" /> </operation> </service>
8、现在要配置一下web.xml了
内容如下:
- <?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">
- <servlet>
- <servlet-name>AxisServlet</servlet-name>
- //注册axis2的servlet
- <servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class>
- <load-on-startup>1</load-on-startup>
- </servlet>
- <servlet-mapping>
- <servlet-name>AxisServlet</servlet-name>
- <url-pattern>/services/*</url-pattern>
- </servlet-mapping>
- //加载spring的配置文件
- <context-param>
- <param-name>contextConfigLocation</param-name>
- <param-value>classpath*:applicationContext.xml</param-value>
- </context-param>
- //增加spring监听器
- <listener>
- <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
- </listener>
- </web-app>
<?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"> <servlet> <servlet-name>AxisServlet</servlet-name>
//注册axis2的servlet <servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping>
//加载spring的配置文件 <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:applicationContext.xml</param-value> </context-param>
//增加spring监听器 <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener>
</web-app>
9、启动tomcat 在浏览器中输入http://localhost:8080/WebService/services/listServices
可以看到一下内容说明我们的服务已经发布成功了
访问
http://localhost:8080/WebService/services/HelloWorld?wsdl
可以查看wsdl
现在我们开始访问我们的服务,我们采用用axis2 的eclipse 插件自动生成客户端
一、根据wsdl自动生成客户端的方式
1、新建一个Java project ,取名为ServiceClient
2、建立一个User Library 取名AXIS2 将axis2 所需要的jar文件加到AXIS2中,然后在
ServiceClient 中引入这个library
3、在eclipse中安装axis2插件
Service Archive Wizard - Eclipse Plug-in 和 Code Generator Wizard - Eclipse Plug-in
注:安装方式可见我的博客中的axis webservice 笔记 安装eclipse axis2 插件 (links 方式)文章
4、(1)选择new->other->Axis2 Wizards-> Axis2 code generator
(2)下一步
(3)下一步
把浏览其中的wsdl地址考到里面
(4) 下一步 直接点next
(5)选择生成到我们刚建好的ServiceClient的src 目录中
然后点击finish,这样就可一生成客户端了,刷新项目就可以看到了
5、生成的目录结构如图所示:
二、新建ServiceClient.Java 内容如下
- package sample.service;
- public class ServiceClient {
- /**
- * @param args
- */
- public static void main(String[] args) throws java.lang.Exception{
- //创建存根类
- HelloWorldStub stub = new HelloWorldStub();
- //设置相应的方法的值
- HelloWorldStub.SayHello sayHello = new HelloWorldStub.SayHello();
- sayHello.setName("张三");
- //调用服务的相应方法并获得返回值
- HelloWorldStub.SayHelloResponse response = stub.sayHello(sayHello);
- System.out.println(response.get_return());
- }
- }
package sample.service; public class ServiceClient { /** * @param args */ public static void main(String[] args) throws java.lang.Exception{
//创建存根类 HelloWorldStub stub = new HelloWorldStub();
//设置相应的方法的值 HelloWorldStub.SayHello sayHello = new HelloWorldStub.SayHello(); sayHello.setName("张三");
//调用服务的相应方法并获得返回值 HelloWorldStub.SayHelloResponse response = stub.sayHello(sayHello); System.out.println(response.get_return()); } }
运行这个java类,可以看到console中
打印出:hello张三 ,说明我们已经调用成功了。
