@RequestMapping对不同参数的接收方式示例详解

@RequestMapping("/simple")
    public  String simpleParam(String name,int age){
        String username = name;
        int userAge = age;
        System.out.println(username+"========"+userAge);
        return  "OK";
    }

@RequestMapping("/simple2")
    public  String simpleParam2(@RequestParam(value = "name",required = false) String s_name, @RequestParam(name = "age") int s_age){
        String username = s_name;
        int userAge = s_age;
        System.out.println(username+"========"+userAge);
        return  "OK";
    }

public class User {
    String name;
    int age;
        //省略get和set方法，toString()
}
