playframework-2.0 - IllegalStateException : No value MyAuthProvider. handleSignup(ctx());

Question

调用时

MyAuthProvider.handleSignup(ctx());

Play 返回IllegalStateException:无值

只有在调用之前调用 myAccount.save() 时才会发生这种情况。

myAccount 是我在让系统处理注册和创建用户之前首先创建的实体模型。我使用 Ebeans。

我使用 Play 命令解决了这个问题:

play clean
play clean-files;
play update
play reload
play compile
play run

如果您使用的是激活器，请用激活器替换游戏。
