turismo -- a sinatra-like Java web framework.

Quick intro

public class AppRoutes extends RoutesList {
    protected void map() {
        get("/", new Action() {
            public void run() {
                print("Hello World!");
            }
        });
    }
}

Using wildcards and resource identifiers

public class AppRoutes extends RoutesList {
    protected void map() {
        get("/wildcard/*/:id", new Action() {
            public void run() {
                String id = params("id");
                print("wildcard id " + id);
            }
        });
        get("/alias/*/:id", "/wildcard/*/:id");
    }
}

Testing with standalone jetty

package com.ghosthack.turismo.example;

import com.ghosthack.turismo.action.*;
import com.ghosthack.turismo.routes.*;

public class AppRoutes extends RoutesList {

    @Override
    protected void map() {
        get("/", new Action() {
            @Override
            public void run() {
                print("Hello World!");
            }
        });
    }

    public static void main(String[] args) throws Exception{
        JettyHelper.server(8080, "/*", AppRoutes.class.getName());
    }

}

Getting started, as webapp

Using a webapp descriptor: web.xml

<?xml version="1.0" encoding="utf-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
  version="2.5">

  <servlet>
    <servlet-name>webapp-servlet</servlet-name>
    <servlet-class>com.ghosthack.turismo.servlet.Servlet</servlet-class>
    <init-param>
      <param-name>routes</param-name>
      <param-value>com.ghosthack.turismo.example.WebAppRoutes</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>webapp-servlet</servlet-name>
    <url-pattern>/*</url-pattern>
  </servlet-mapping>

</web-app>

Implementing routes

package com.ghosthack.turismo.example;

import com.ghosthack.turismo.action.*;
import com.ghosthack.turismo.routes.*;

public class WebAppRoutes extends RoutesList {

    @Override
    protected void map() {
        get("/", new Action() {
            @Override
            public void run() {
                print("Hello World!");
            }
        });
    }

}

Rendering "templates"

Using a jsp:

get("/render", new Action() {
    public void run() {
        req().setAttribute("message", "Hello Word!");
        jsp("/jsp/render.jsp");
    }
});

And the render.jsp contains:

<%=request.getAttribute("message")%>

Other mappings

Methods for GET, POST, PUT, DELETE, HEAD, OPTIONS, TRACE

post("/search", new Action() {
    public void run() {
        String query = req().getParameter("q");
        print("Your search query was: " + query)
    }
});

The default route in RoutesMap/RoutesList sends a 404. Rewire with another action:

route(new Action() {
    public void run() {
        try {
            res().sendError(404, "Not Found");
        } catch (IOException e) {
            throw new ActionException(e);
        }
    }
});

Multipart

post("/image", new Action() {
    void run() {
        MultipartRequest request = MultipartFilter.wrapAndParse(req());
        String[] meta = request.getParameterValues("image");
        byte[] bytes = (byte[]) request.getAttribute("image");
        LOG.info("type: %s, name: %s, %d bytes", meta[0], meta[1], bytes.length);
    }
});
