package com.ttpfx.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HelloController {
    @RequestMapping(path = "/hello")
    public void hello() {
        System.out.println("HelloController.hello()方法执行了");
    }
}
