A more modern framework for Java application development: faster, smaller, and freer. No Spring, no Servlet, no JavaEE;Independent lightweight ecology. The main frame is only 0.1 MB.

@Controller
public class App {
    public static void main(String[] args) {
        Solon.start(App.class, args);
    }

    @Get
    @Socket
    @Mapping("/hello")
    public String hello(@Param(defaultValue = "java") String name) {
        return String.format("Hello %s!", name);
    }
}

• Support Service Mesh architecture deployment scheme
• Support jdk8, jdk11, jdk17, jdk19 at the same time
• No Spring, no Servlet, no JavaEE; independent lightweight ecology
