1.增加实例化bean的class类
import java.io.IOException;
import javax.servlet.GenericServlet;
import javax.servlet.Servlet;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;
public class ServiceInfoProxy extends GenericServlet {
private static final long serialVersionUID = 1L;
private String targetBean;
private Servlet proxy;
@Override
public void service(ServletRequest arg0, ServletResponse arg1)
throws ServletException, IOException {
proxy.service(arg0, arg1);
}
@Override
public void init() throws ServletException {
this.targetBean = getServletName();
getServletBean();
proxy.init(getServletConfig());
}
private void getServletBean() {
WebApplicationContext wac = WebApplicationContextUtils.getRequiredWebApplicationContext(getServletContext());
this.proxy = (Servlet)wac.getBean(targetBean);//get proxyBean}
}
2．逻辑类TaskStatusCallback继承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 方式逻辑实现");
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
System.out.println("post 方式逻辑实现");
}
@Override
public void init(ServletConfig config) throws ServletException {
System.out.println("~~~START1~~~");
}
}
3．spring.xml里面加入以下内容：
<bean id="taskStatusCallback" class="ly.webApi.TaskStatusCallback"/>
4．web.xml下发布接口，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>
<!--发布路径-->
<url-pattern>/service/taskStatusCallback/*</url-pattern></servlet-mapping>
