Go 的全棧 Web 框架，Revel v0.11.2 發布
Revel 是一個Go 語言高效的，全棧Web開發框架，靈感源于Rails 和 Play!。
特性
Hot Code Reload
Edit, save, and refresh. Revel compiles your code and templates for you, so you don't miss a beat. Code doesn't compile? It gives you a helpful description. Run-time code panic? Revel has you covered.
Comprehensive
Revel provides routing, parameter parsing, validation, session/flash, templating, caching, job running, a testing framework, and even internationalization.
High Performance
Revel builds on top of the Go HTTP server, which was recently benchmarked to serve three to ten times as many requests as Rails across a variety of loads.
Framework Design
Synchronous
The Go HTTP server runs each request in its own goroutine. Write simple callback-free code without guilt.
Stateless
Revel provides primitives that keep the web tier stateless for predictable scaling. For example, session data is stored in the user cookie, and the cache is backed by a memcached cluster.
Modular
Revel is built around composable middleware called filters,
which implement nearly all request-processing
functionality. Developers have the freedom to replace the default
filters with custom implementations (e.g. a custom router).

user.Username, user.Password, user.Name)
if err != nil {

}
c.Session["user"] = user.Username
c.Flash.Success("Welcome, " + user.Name)
return c.Redirect(Hotels.Index)
