)

func main() {
	// new app
	app := baa.New()

	// register cache
	app.SetDI("cache", cache.New(cache.Options{
		Name:     "cache",
        Prefix:   "MyApp",
		Adapter:  "memory",
		Config:   map[string]interface{}{},
	}))

	// router
	app.Get("/", func(c *baa.Context) {
		ca := c.DI("cache").(cache.Cacher)
		ca.Set("test", "baa", 10)
        var v string
		ca.Get("test", &v)
		c.String(200, v)
	})

	// run app
	app.Run(":1323")
}

you should import cache adpater before use it, like this:

import(
    "github.com/go-baa/baa"
    "github.com/go-baa/cache"
    _ "github.com/go-baa/cache/memcache"
    _ "github.com/go-baa/cache/redis"
)
