接缝焊接 CDI

Question

我想知道如果有一个相当于下面的seam 2.2 annotation

@Interceptor(around = {SomeInterceptor.class})

带有焊接注释。 我对 Seam 和 Weld 都不是很熟悉。 "around" 到底是什么意思？它与调用其他拦截器的命令有关吗？还是某种继承？

查看https://access.redhat.com/documentation/en-US/JBoss_Enterprise_Web_Platform/5/html/Seam_Reference_Guide/ch07s11.html

"Where interceptor order is important, add @Interceptor annotations to your interceptor classes to specify a particular order of interceptors."

 @Interceptor(around={BijectionInterceptor.class, 
                  ValidationInterceptor.class, 
                  ConversationInterceptor.class}) 
 public class LoggedInInterceptor { 
... 
}

所以只有一个拦截器不是很有用......
