Spring MVC 请求参数获取

GET

1. 请求 默认的 Content-Type = "application/x-www-form-urlencoded"
   所以 当Spring 使用
   @RequestMapping(value = "/pets", method=RequestMethod.GET,consumes = "application/x-www-form-urlencoded")
   //进行注解时不会返回415 错误[UNSUPPORTED_MEDIA_TYPE]。

2. 参数直接放在方法里
   @RequestMapping(value = "/pets", method =RequestMethod.GET,consumes = "application/x-www-form-urlencoded" )
   public void getPet(String id, Model model) {
   System.out.println(id);
   }
   //请求参数 localhost:8080/pets?id=1
   //打印结果 1

3. 含有参数的对象放在方法里

   @RequestMapping(value = "/pets", method =RequestMethod.GET,consumes = "application/x-www-form-urlencoded" )                              
     public void getPet(PetForm dataForm, Model model) {       
            System.out.println(dataForm.getId());
     }
   //请求参数 localhost:8080/pets?id=1
   //打印结果 1
