undertow multiple webservices url

问题

I want something like this on my address. How I can bind servlet1, servlet2, servlet3 to localhost:8080 so I can have different url to call such as

localhost:8080/servlet

localhost:8080/servlet1

localhost:8080/servlet2

localhost:8080/servlet3

I have this code that only work for thw last url(servlet) added

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);

回答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.
);

Please test with this command from shell:

# 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/
