@RequestParam 注解如果是个map类型,那么mvc适配器就将参数封装到map中
请求地址:localhost:8080/test?name=testname&pwd=123456
@RequestMapping("/test") public Object hello2(@RequestParam Map query) { String name = (String) query.get("name"); String pwd = (String) query.get("pwd"); System.out.println(name); System.out.println(pwd); return query; }
返回参数:
{ "name": "testname", "pwd": "123456" }
