java 開發 webAPI 接口服務端 方法2

和方法1比較不用增加實例化bean的class類， 初始化的時候需要聲明支持注入

1．邏輯類TaskStatusCallback繼承HttpServlet，如下：

    public class TaskStatusCallback extends HttpServlet{

        public TaskStatusCallback() {
            super();
        }

   protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException,                 IOException {
System.out.println("get 方式邏輯實現");
        }

    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException,                 IOException {
            System.out.println("post 方式邏輯實現");
       　}

   

/**
 * 聲明支持注入
 * @param config
 * @throws ServletException
 */

@Override
public void init(ServletConfig config) throws ServletException {
    SpringBeanAutowiringSupport.processInjectionBasedOnServletContext(this,
            config.getServletContext());

}

    

　　}

    3．spring.xml裏面加入以下內容：

        <bean id="taskStatusCallback" class="ly.webApi.TaskStatusCallback"/>

     4．web.xml下發布接口，如下：

         <servlet>
                <servlet-name>taskStatusCallback</servlet-name>
                <servlet-class>ly.utils.ServiceInfoProxy</servlet-class>
                <load-on-startup>3</load-on-startup>
          </servlet>
          <servlet-mapping>

                <servlet-name>taskStatusCallback</servlet-name>

                <!--發佈路徑-->

                <url-pattern>/service/taskStatusCallback/*</url-pattern>
          </servlet-mapping>
