해결 방법

먼저 secret 값을 얻는다.

% /usr/local/activator/bin/activator

[guid-migration] $

[guid-migration] $ playGenerateSecret

[info] Generated new secret: =H7u9z7gzqk?20_U[DdL=l85uvhnoidD8jGd372ONJc_]I2TVtp:3z;O[VQSSI8`

[success] Total time: 0 s, completed 2017. 4. 17 오후 9:48:56

해당 secret 값을 conf/application.conf에 저장한다.

play.crypto.secret="changeme"

play.crypto.secret="=H7u9z7gzqk?20_U[DdL=l85uvhnoidD8jGd372ONJc_]I2TVtp:3z;O[VQSSI8`"

더 이상 에러는 발생하지 않는다.
