springboot cookie操作（@Cookie）

 

*******************************

相关注解

 

@Cookie：使用注解读取cookie数据

@Target({ElementType.PARAMETER})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface CookieValue {
    @AliasFor("name")
    String value() default "";

    @AliasFor("value")
    String name() default "";

    boolean required() default true;

    String defaultValue() default "\n\t\t\n\t\t\n\ue000\ue001\ue002\n\t\t\t\t\n";
}

 

**********************************

示例

 

@RestController
public class HelloController {

    @RequestMapping("/hello2")
    public String hello2(HttpServletResponse response){
        Cookie cookie=new Cookie("name","瓜田李下");
        response.addCookie(cookie);

        return "success 2";
    }

    @RequestMapping("/hello3")
    public String hello3(HttpServletRequest request,@CookieValue("name") String name){
        System.out.println(name);

        Cookie[] cookies=request.getCookies();
        for (Cookie cookie:cookies){
            System.out.println(cookie.getName()+"  "+cookie.getValue());
        }

        return "success 3";
    }
}
