十一、在Web应用中嵌入Axis2 Web Service

有一个最简单的方法就是把axis2.war中的内容作为web app的基础，来进行开发. 不过为了更清楚的了解如何在一个已有的web app中嵌入axis2，那就只能手动了。

11.1、把以下内容copy到已有的web app中

axis2.war/axis2-web

axis2.war/WEB-INF/*

11.2、在web.xml中配置axis2 servlet

<servlet>

       <servlet-name>AxisServlet</servlet-name>

       <display-name>Apache-Axis Servlet</display-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>

11.3、创建自己的Service Bean

package example;

public class HelloWorldService {

public HelloWorldService() {

}

public String hello() {

return "Hello axis2 service!";

}

}

11.4、配置Web Service.

由于axis2嵌入了web app, 所以web service就不用打包成aar,而是直接在/WEB-INF目录下创建相应的文件夹和services.xml

/WEB-INF

/services

/HelloWorld

/META-INF

services.xml

11.5、配置services.xml的内容

<serviceGroup>

<service name="HelloWorldService">

<description>Hello World Service</description>

<parameter name="ServiceClass" locked="false">

example.HelloWorldService

</parameter>

<operation name="hello">

<messageReceiver

class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"/>

</operation>

</service>

</serviceGroup>

11.6. 测试

如果一切OK的话, 在浏览器中输入：

http://localhost:8080/example/services/HelloWorldService?wsdl就应该可以看到输出的wsdl xml.

Done!

11.7、集成Spring

其实在项目中还集成了Spring, 不过这个应该相对简单.

1. 需要把Spring的jar放到/WEB-INF/lib中

2. services.xml中service的ServiceObjectSupplier用org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier

 

HelloWorldSpringService.java

package example;

 

public class HelloWorldSpringService {

public String hello() {

return "Hello spring axis2 service!";

}

}

 

In services.xml:

<serviceGroup>

<service name="HelloWorldService">

<description>Hello World Service</description>

<parameter name="ServiceClass" locked="false">example.HelloWorldService</parameter>

<operation name="hello">

<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />

</operation>

</service>

<service name="HelloWorldSpringService">

<description>Hello World Spring Service</description>

<parameter name="ServiceObjectSupplier">

org.apache.axis2.extensions.spring.receivers.SpringServletContextObjectSupplier

</parameter>

<parameter name="SpringBeanName">HelloWorldSpringService</parameter>

<operation name="hello">

<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />

</operation>

</service>

</serviceGroup>

 

In applicationContext.xml

<bean id="HelloWorldSpringService" class="example.HelloWorldSpringService"/>
