axis2+spring集成

转载自：http://www.cnblogs.com/linjiqin/archive/2011/07/05/2098316.html

1、新建一个web project项目，最终工程目录如下：

注意：本文只注重webservice服务器端的开发，因此com.ljq.client和com.ljq.test忽略不计

2、添加所需jar

精简包

3、接口HelloWorld

package com.ljq.service;

public interface HelloWorld {
    public String greeting(String name);
    public String print();
}

4、接口实现类HelloWorldBean

package com.ljq.service;

public class HelloWorldBean implements HelloWorld {
    public String greeting(String name) {
        return "你好 "+name;
    }

    public String print() {
        return "我叫林计钦";
    }
}

5、webservice类HelloWorldWebService

package com.ljq.service;

import org.apache.axis2.AxisFault;
import org.apache.axis2.ServiceObjectSupplier;
import org.apache.axis2.description.AxisService;
import org.apache.axis2.description.Parameter;
import org.apache.axis2.i18n.Messages;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;

/**
 * 可能出现Axis2 spring bean not found 或者 Spring applicationContext not found。
 * 
 * 解决办法：构建自己的ServiceObjectSupplier，实现接口ServiceObjectSupplier，同时也实现Spring的ApplicationContextAware接口
 * 
 * 
 * @author Administrator
 * 
 */
public class HelloWorldWebService implements ServiceObjectSupplier,
        ApplicationContextAware {
    private static ApplicationContext ctx;

    public Object getServiceObject(AxisService axisService) throws AxisFault {
        Parameter springBeanName = axisService.getParameter("SpringBeanName");
        String beanName = ((String) springBeanName.getValue()).trim();
        if (beanName != null) {
            if (ctx == null)
                throw new AxisFault("applicationContext is NULL! ");
            if (ctx.getBean(beanName) == null)
                throw new AxisFault("Axis2 Can't find Spring Bean: " + beanName);
            return ctx.getBean(beanName);
        } else {
            throw new AxisFault(Messages.getMessage("paramIsNotSpecified",
                    "SERVICE_SPRING_BEANNAME"));
        }

    }

    public void setApplicationContext(ApplicationContext ctx)
            throws BeansException {
        this.ctx = ctx;
    }

}

6、配置web.xml文件

<?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">
    <!-- 添加spring监听器 -->
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    <!-- 加载spring的配置文件 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </context-param>

    <!-- 注册axis2的servlet -->
    <servlet>
        <servlet-name>AxisServlet</servlet-name>
        <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>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

7、在WEB-INF目录下配置applicationContext.xml（不存在则自己创建）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN"
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
    <bean id="applicationContext"
        class="org.apache.axis2.extensions.spring.receivers.ApplicationContextHolder" />
    <bean id="helloWorld" class="com.ljq.service.HelloWorldBean"></bean>
</beans>

8、在WEB-INF\services\axis\META-INF\目录下配置services.xml（不存在则自己创建）

<?xml version="1.0" encoding="UTF-8"?>
<service name="hwWebService">
    <description>axis2与spring集成案例</description>
    <!-- 通过ServiceObjectSupplier参数指定SpringServletContextObjectSupplier类来获得Spring的ApplicationContext对象 -->
    <parameter name="ServiceObjectSupplier">
        org.apache.axis2.extensions.spring.receivers.SpringAppContextAwareObjectSupplier
    </parameter>
    <!-- 
       SpringBeanName固定的不能改
       helloWorld是spring中注册的实现类得id
     -->
    <parameter name="SpringBeanName">helloWorld</parameter>
    <!-- 
    在这里最值得注意的是<messageReceivers>元素，该元素用于设置处理WebService方法的处理器。
    例如，getGreeting方法有一个返回值，因此，需要使用可处理输入输出的RPCMessageReceiver类，
    而update方法没有返回值，因此，需要使用只能处理输入的RPCInOnlyMessageReceiver类。
     -->
    <messageReceivers>
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
            class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" />
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
            class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
    </messageReceivers>
</service>

axis2+spring集成到此已经开发完成，接下把工程部署到tomcat，

然后通过http://localhost:8083/axis2spring/services/hwWebService?wsdl访问
