程序包 cn.taketoday.session

类 SessionMethodArgumentResolver

java.lang.Object

cn.taketoday.session.SessionManagerOperations

cn.taketoday.session.SessionMethodArgumentResolver

所有已实现的接口:

ParameterResolvingStrategy

public class SessionMethodArgumentResolver
extends SessionManagerOperations
implements ParameterResolvingStrategy

for WebSession Type-based parameter resolving

Like following example

 
  // if request not contains a WebSession create new one
  @GET("/captcha")
  public BufferedImage captcha(WebSession session) {
     ...
     session.setAttribute(RAND_CODE, randCode);
     return image;
  }
  // WebSession may be null
  @GET("/test")
  public void nullable(@Nullable WebSession session) {
     ...
     if (session == null) {

     }
     else {

     }
  }
