[security] Error on visit "/uaa/login" request mapping

[0604hx]

Hi, I check out branch "security" , build success and run Eureka/Gateway/Customer/Account/Authentication services.

Then visit to http://localhost:8765/api/customer that redirect to http://localhost:9999/uaa/login as expected. But I get follow error message on browser

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
Circular view path [login]: would dispatch back to the current handler URL [/uaa/login] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)

And found error message on Authentication Service :

2017-08-02 22:21:20.393 ERROR 37120 --- [nio-9999-exec-1] o.a.c.c.C.[.[.[.[dispatcherServlet]      : Servlet.service() for servlet [dispatcherServlet] in context with path [/uaa] threw exception [Circular view path [login]: would dispatch back to the current handler URL [/uaa/login] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)] with root cause

It seem /uaa/login is not mapping correctly.
