postman基本使用+post请求结构

对应的springboot代码(?)

@Controller
public class hellocontrller {
@ResponseBody
    @RequestMapping("hello")
    public String f(@RequstParam String a){

    return  "header"+a;
}

header中有这些键值对，设置了一些请求的方式
如果要在springboot中获取这里的键值对

@Controller
public class hellocontrller {
@ResponseBody
    @RequestMapping("hello")
    public String f(@RequestHeader String a){

    return  "header"+a;
}
}

对应@RequestBody,在contreller中只能用实体类接收，还需设置header具体见

  public void downloadAllClassmate(@RequestBody Tb1 tb1, HttpServletResponse response)
