彈簧加載堆棧跟蹤

IIUC彈簧加載使我可以在不重新部署的情況下更改java服務器代碼，它可以工作，但是我得到了一個可笑的長棧跟蹤。這是什麼意思？彈簧加載堆棧跟蹤

我的班，我可以重新加載，無需重新啓動碼頭

package hello; 

import org.springframework.web.bind.annotation.RestController; 
import org.springframework.web.bind.annotation.RequestMapping; 

@RestController 
public class HelloController { 

    @RequestMapping("/") 
    public String index() { 
     return "Greetings from Spring Boot!"; 
    } 

}

可是爲什麼我得到的堆棧跟蹤，如何解決呢？

有什麼關係（將它從springloaded-1.2.2.BUILD-SNAPSHOT.jar重命名爲springloaded-1.2.0.RELEASE.jar）。簡單的谷歌向我展示了關於springloaded jar的結果。這是一個有討論的示例帖子，https://github.com/spring-projects/spring-loaded/issues/98 –

@KiranJoshi我不確定。該文檔沒有幫助。我不知道要結合什麼。 –

你可以添加這個依賴於你的pom.xml， org.springframework 彈簧式 1.2.5.RELEASE –

關於上述和我未來的參考，我提出這個答案。

將依賴關係從1.2.1.RELEASE更改爲1.2.5.RELEASE確實有效。
