對不起,如果這已經回答,我無法找到它。java + groovy _maven在嵌入式tomcat,控制器的彈簧啓動,但錯誤
我已經使用spring引導創建了新項目。
我的要求是,我有一些java類,一些常規類,他們應該能夠互相呼叫。
我使用Maven和由 MVN春季啓動運行我的tomcat嵌入:運行 問題是,RestController這是Java類那裏,我可以把它叫做REST URL。
但是,在Groovy中的控制器不能被調用,並給我錯誤。
curl localhost:8080/
{"timestamp":1455913384508,"status":404,"error":"Not Found","message":"No message available","path":"/"}
好的部分是我可以從java調用groovy類。
以下是我的文件。

這工作: 捲曲本地主機:8080 /你好,從春天啓動 問候!
非常感謝您的幫助。
這工作。非常感謝。 Spring引導網站的原樣複製。這是缺少@RequestMapping(路徑=「目的地」) – bhai
我是非常新的SO,不能投票和「接受答案」沒有出現。 :(幾個月後,我可能會有一些聲譽。 – bhai
