本文整理了Java中org.eclipse.jetty.servlet.ServletHandler类的一些代码示例，展示了ServletHandler类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。ServletHandler类的具体详情如下：
包路径：org.eclipse.jetty.servlet.ServletHandler
类名称：ServletHandler

ServletHandler介绍

[英]Servlet HttpHandler.

This handler maps requests to servlets that implement the javax.servlet.http.HttpServlet API.

This handler does not implement the full J2EE features and is intended to be used directly when a full web application is not required. If a Web application is required, then this handler should be used as part of a org.eclipse.jetty.webapp.WebAppContext.

Unless run as part of a ServletContextHandler or derivative, the #initialize()method must be called manually after start().
[中]Servlet HttpHandler。
这个处理程序将请求映射到实现javax的servlet。servlet。http。HttpServlet API。
此处理程序不实现完整的J2EE功能，并打算在不需要完整的web应用程序时直接使用。如果需要Web应用程序，则此处理程序应作为org.eclipse.jetty.webapp.WebAppContext的一部分使用。
除非作为ServletContextHandler或派生函数的一部分运行，#initialize（）方法必须在start（）之后手动调用。

代码示例

代码示例来源：origin: google/data-transfer-project

public void registerServlet(String path, Servlet servletContainer) {
 ServletHolder servletHolder = new ServletHolder(Source.EMBEDDED);
 servletHolder.setName("Data Transfer Project");
 servletHolder.setServlet(servletContainer);
 servletHolder.setInitOrder(1);
 ServletContextHandler handler = new ServletContextHandler(ServletContextHandler.NO_SESSIONS);
 handler.setContextPath("/");
 handlers.add(handler);
 handler.getServletHandler().addServletWithMapping(servletHolder, path);
}

ServletContextHandler context = new ServletContextHandler(server, "/", ServletContextHandler.SESSIONS);
context.setServletHandler(servletHandler);
ServletManager.getInstance().addServletContext(url.getParameter(Constants.BIND_PORT_KEY, url.getPort()), context.getServletContext());
