servlet

servlet可以没有对应的<servlet-mapping>标签

<servlet>
	<servlet-name>ZfInitialServlet</servlet-name>
	<servlet-class>com.cloud.base.InitialServlet</servlet-class>
	<load-on-startup>99</load-on-startup>
</servlet>

对应servlet类

public class InitialServlet implements Servlet {

	@Override
	public void destroy() {
		// TODO Auto-generated method stub

	}

	@Override
	public ServletConfig getServletConfig() {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public String getServletInfo() {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public void init(ServletConfig config) throws ServletException {
		//初始化项目路径
		SystemProperties.setRootPath(config.getServletContext().getRealPath("/"));
	}

	@Override
	public void service(ServletRequest arg0, ServletResponse arg1)
			throws ServletException, IOException {
		// TODO Auto-generated method stub

	}

}

<load-on-startup>99</load-on-startup>

表示启动时加载顺序,越小越早加载
