Bard is a web framework that is easy to use and extend.

It is not stable now.

Requirements

• Java 1.8
• Maven 3

Features

Very Easy to Use

You can just write handlers like this:

@Produces("application/json")
public class SimpleHandler extends Handler {

    @GET
    @Path("/add")
    @Doc("Add two numbers")
    public int add(
        @QueryParam("a") @Required int a,
        @QueryParam("b") @Required int b) {
        return a + b;
    }
    
}

Very Easy to Extend.

For example, you can define your custom injectors like this:

@BindTo(QueryParam.class)
public class QueryParamInjector extends Injector<QueryParam> {

    @Before
    public void getParams() {
        context.putCustom("param", annotation.value());
        String param = context.getRequest().getParameter(annotation.value());
        if (param == null) {
            context.setInjectorVariable(null);
            return;
        }
        TypeParser parser = TypeParser.newBuilder().build();
        context.setInjectorVariable(parser.parse(param, context.getInjectorVariableType()));
    }

    @Override
    public void generateDoc() {
        docParameter.name = annotation.value();
        docParameter.type = context.getInjectorVariableType();
        docParameter.belongs = "url";
    }
}

Auto Generate Beautiful Document

No more code needed, once your handler is written, the API documents is right there for you. The users could also try the APIs in the web UI. Isn't that cool?

Build A Self Contained Directory That Is Ready to Deploy

Just with one command mvn package bard:standalone, this framework will generate a self contained directory which is ready to deploy. It contains directory conf to store config files, bin to store start up and shut down scripts, lib to store library JARs and log to store all the logs for you.

Just run bin/server.sh start | restart | stop, you can control your server.

Or Run In Your Favorite Servlet Container

If you want to build a WAR package in order to run in a servlet container, that is easy, too. Just run mvn package bard:war, then you will get a WAR package.

It is better to manage the dependency with maven:

<dependency>
    <groupId>com.bardframework</groupId>
    <artifactId>bard-core</artifactId>
    <version>0.1.0</version>
</dependency>
<dependency>
