1.2 运行Hello World

我们就在默认生成的 App.java 文件中写上程序员入门必备的 Hello World。

  1. /**
  2.  * Hello world!
  3.  */
  4. public class App {
  5.     public static void main(String[] args) {
  6.         Blade.me().get("/",    (request, response) -> response.text("Hello World")).start(App.class, args);
  7.     }
  8. }

运行 main 函数，此时你会在控制台看到这样的输出信息
