使用Jetty以编程方式部署servlet

标签: spring servlets jetty context.xml

我有一个servlet,我希望使用Jetty以编程方式部署。 servlet使用Spring,它的web.xml指向Spring上下文XML文件,正如您所期望的那样。

目前,我只是尝试Jetty文档中的示例代码,但使用自己的servlet:

Server server = new Server(8080);

ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
server.setHandler(context);

context.addServlet(new ServletHolder(new BatchReceiver()),"/br/*");

server.start();
server.join();

这会导致以下异常:

如何设置我的servlet以便Jetty知道它的web.xml和Spring上下文在哪里?

真的很感激任何帮助!

修改

所以,显然我不需要web.xml但我需要将Jetty指向我的Spring上下文。我尝试过以下内容:

context.setInitParameter("contextConfigLocation", "classpath*:**/*Context.xml");

但它不起作用(仍产生相同的异常)。我也尝试在ServletHolder上设置“contextConfigLocation”无济于事。

答案 0 :(得分:17)

对于那些感兴趣的人,我按照以下方式开展工作:

Server server = new Server(8090);

ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/batch");

// Setup Spring context
context.addEventListener(new ContextLoaderListener());
context.setInitParameter("contextConfigLocation", "classpath*:**/testContext.xml");

server.setHandler(context);

// Add servlets
context.addServlet(new ServletHolder(new BatchReceiver()), "/receiver/*");
context.addServlet(new ServletHolder(new BatchSender()), "/sender/*");       

server.start();
server.join();

我缺少的关键步骤是

context.addEventListener(new ContextLoaderListener());

加载Spring上下文。

如果你想处理web.xml你需要使用WebappContext,那么servlet上下文对web.xml的知识一无所知
