了解多个网络服务 URL

Question

我想在我的地址上有这样的东西。如何将 servlet1、servlet2、servlet3 绑定到 localhost：8080，以便我可以调用不同的 url，例如

本地主机：8080/servlet

本地主机：8080/servlet1

本地主机：8080/servlet2

本地主机：8080/servlet3

我有这个代码仅适用于添加的最后一个网址（servlet）

DeploymentInfo servletBuilder = deployment()
                .setClassLoader(ServletServer.class.getClassLoader())
                .setContextPath(MYAPP)
                .setDeploymentName("test.war")
                .addServlets(
                        servlet(servletName,  x)
                        .addInitParam("message", output)
                        .addMapping("/"+servletName.toLowerCase()));
        DeploymentManager manager = defaultContainer().addDeployment(servletBuilder);
        manager.deploy();
        HttpHandler servletHandler = manager.start();
        path = Handlers.path(Handlers.redirect(MYAPP))
                .addPrefixPath(MYAPP, servletHandler);

Answer 1

DeploymentInfo servletBuilder = deployment()
.addServlets(
 servlet("servlet1", YourServlet1.class).addInitParam("param1", "Value A")
.addMapping("/servlet1/*"),
 servlet("servlet2", YourServlet2.class).addInitParam("param2", "Value B")
.addMapping("/servlet2/*"),
 servlet("servlet3", YourServlet3.class).addInitParam("param2", "Value C")
.addMapping("/servlet3/*")  // as many as you like.
);

请使用 shell 的以下命令进行测试：

# Runs in background
java -cp target/undertowservlet-jar-with-dependencies.jar servlet.Servletrver &
curl http://localhost:8080/myapp/msgA/
curl http://localhost:8080/myapp/msgB/
curl http://localhost:8080/myapp/msgC/
