支持多个网络服务 url

Question

我想在我的地址上写这样的东西。我如何将 servlet1、servlet2、servlet3 绑定到 localhost:8080，这样我就可以调用不同的 url，例如

localhost:8080/servlet

localhost:8080/servlet1

localhost:8080/servlet2

localhost:8080/servlet3

我有这个代码只适用于最后添加的 url(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.
);

                            .addInitParam("message", "Hello BBB\n")
                            .addMapping("/msgB/*"),
                            servlet("MessageServletC", MessageServletC.class)
                            .addInitParam("message", "Hello CCC\n")

            DeploymentManager manager = defaultContainer().addDeployment(servletBuilder);
            manager.deploy();

            HttpHandler servletHandler = manager.start();
            PathHandler path = Handlers.path(Handlers.redirect(MYAPP))
                    .addPrefixPath(MYAPP, servletHandler);
            Undertow server = Undertow.builder()
                    .addHttpListener(8080, "localhost")
                    .setHandler(path)
                    .build();
            server.start();
        } catch (ServletException e) {
            throw new RuntimeException(e);
        }
    }
}

请使用来自 shell 的命令进行测试：

# 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/
