MockMVCでServletExceptionが発生し、テストができない。

#やりたいこと
Controllerクラスの結合（システム？）テスト

##やったこと
テストクラスの生成

Resolverが３つあるのは試行した結果です。

###起きたエラー

text
1javax.servlet.ServletException: Circular view path [hello]: would dispatch back to the current handler URL [/hello] again. Check your ViewResolver setup! (Hint: This may be the result of an unspecified view, due to default view name generation.)
2	at org.springframework.web.servlet.view.InternalResourceView.prepareForRendering(InternalResourceView.java:205)

###ためしたこと

上のResolverの追加

(初期)viewResolver Only --> ☓
Add viewResolver_ --> ☓
Add WebTemplateResolver --> ☓

テストクラスのアノテーションをはずす

参考にしている翔泳社の本では、なくていいと書かれていたので。
