@RequestParam和@RequestBody区别

 

1. @RequestParam 用来处理Content-Type为application/x-www-form-urlencoded(默认类型如果不指定)

    GET和POST请求传的参数会自动转换赋值到@RequestParam 所注解的变量上

    例1: http://localhost:8080/test?name=zhangsan&age=30

@RequestMapping("/test")
public String test(@RequestParam Map<String,String>  param){
       param.forEach((key,value)->{
            System.out.println("key="+key+",value="+value);
        });
    }

如上打印结果为:

key=name,value=zhangsan
key=age,value=30

 

例2: http://localhost:8080/test?name=zhangsan

@RequestMapping("/test")
public String test(@RequestParam String name){
       System.out.println("name="+zhangsan);
   }
 

如上打印结果为:

name=zhangsan
