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.

1. 把以下内容copy到已有的web app中

axis2.war/axis2-web
axis2.war/WEB-INF/*

2. 在web.xml中配置axis2 servlet

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


3. 创建自己的Service Bean

package example;
public class HelloWorldService {
    public HelloWorldService() {
    }
    public String hello() {
        return "Hello axis2 service!";
    }
}


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


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>


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!

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"/>
