springboot里面有以下几种方式获取数据的形式

后面一直 next就生成项目了，
接下来创建一个实体类

 // path
    @RequestMapping("hello/{name}")
    public String hello(@PathVariable String name) {
        return "hello " + name + " !!";
    }

    // query string get
    @RequestMapping("hello2")
    public String hello2(@RequestParam String name,
                        @RequestParam String no) {
        return String.format("hello %s, %s !!!", name, no);
    }

    // form data  post
    @RequestMapping("hello3")
    public String hello3(StudentModel student) {
        return String.format("hello %s, %s !!!", student.getName(), student.getNo());
    }

    // json
    @RequestMapping("hello4")
    public String hello4(@RequestBody StudentModel student) {
        return String.format("hello %s, %s !!!", student.getName(), student.getNo());
    }
