blade: A Java repository from JeffreyWei

What Is Blade?

Blade is a lightweight MVC framework. It is based on the principles of simplicity and elegance. If you like it, please star / fork. Thx 😊

Features

Overview

Simplicity: The design is simple, easy to understand and doesn't introduce many layers between you and the standard library. The goal of this project is that the users should be able to understand the whole framework in a single day.
Elegance: blade supports the RESTful style routing interface, has no invasive interceptors and provides the writing of DSL grammar.

Get Start

To get started, first include the Blade library :

Grab via Maven：

<dependency>
	<groupId>com.bladejava</groupId>
	<artifactId>blade-mvc</artifactId>
	<version>2.0.0</version>
</dependency>

or Gradle:

compile 'com.bladejava:blade-mvc:2.0.0'

Create Main method like this：

public static void main(String[] args) {
    Blade blade = Blade.me();
    blade.get("/", (req, res) -> {
        res.text("Hello Blade");
    }).start();
}

Run it and point your browser to http://localhost:9000. There you go, you've just created your first Blade app!

API Example

public static void main(String[] args) {
    Blade blade = Blade.of();
    blade.get("/user/21", getxxx);
    blade.post("/save", postxxx);
    blade.delete("/del/21", deletexxx);
    blade.put("/put", putxxx);
}

REST URL Parameters

public static void main(String[] args) {
    Blade blade = Blade.of();
    blade.get("/user/:uid", (request, response) -> {
		Integer uid = request.queryInt("uid").get();
		response.text("uid : " + uid);
	});
	
    blade.get("/users/:uid/post/:pid", (request, response) -> {
		Integer uid = request.queryInt("uid").get();
		Integer pid = request.queryInt("pid").get();
		String msg = "uid = " + uid + ", pid = " + pid;
		response.text(msg);
	});
	
    blade.start();
}

Form URL Parameters

public static void main(String[] args) {
    Blade blade = Blade.of();
    blade.get("/user", (request, response) -> {
		Integer uid = request.queryInt("uid").get();
		response.text("uid : " + uid);
	}).start(Application.class);
}

Upload File

public void upload_img(@MultipartParam FileItem fileItem){
    if(null != fileItem){
        File file = fileItem.getFile();
        String fileRealPath = "your upload file path!";
        nioTransferCopy(file, fileRealPath);
    }
}

Route Web Hook

public static void main(String[] args) {
    Blade blade = Blade.of();
    blade.before("/.*", (request, response) -> {
        System.out.println("before...");
    }).start();
}
