我发现了此 Primefaces教程.我感兴趣的是，有没有办法用纯JSF达到相同的结果?

I found this Primefaces tutorial. I'm interested is there any possible way to make the same result with pure JSF?

推荐答案

看看JCA，并四处寻找提供文件I/O的优质JCA适配器.如果您使用的是Java EE应用程序，则可能希望使用容器公开的资源(而不是原生")正确实现的JCA适配器也可以/应该提供的事务优势(ACID，回滚等).通过接触容器外部的资源(文件，套接字等)，可以使部署安全性正常运行.

Take a look at JCA, and look around for a good JCA adapter that provides file i/o. if you're working in a Java EE app, you probably want the transactional advantages that a properly implemented JCA adapter can/should provide (ACID, rollback, etc.) also, using a resource exposed by the container rather than "going native" will allow deployment security to operate properly wrt touching resources outside the container (files, sockets, etc.).
