我本週升級到Spring STS的新3.9.0版本。除了當我啓動一個Spring Boot web應用程序(spring啓動版本1.5.3)時,一切都很好,我得到一個錯誤。Spring STS 3.9.0與Spring Boot devtools問題

An internal error occurred during: "Ready state poller".

會話數據:

一切工作與服務器當我改變代碼除,devtools不會重新加載該應用程序。我必須手動重新啓動它。

我最初使用現有工作空間(它自動升級),但我也試着:

  • 啓動Eclipse與-clean
  • 切換到進口的喜好和相同的項目,一個完全新的工作區,
  • 切換到一個全新的工作空間沒有首選項,但相同的項目,然後手動導入首選項。
  • 將Spring Boot升級到1.5.6(其中包括devtools)。

如果我切換到全新的工作區,導入項目並從未導入我的設置,它終於開始沒有錯誤。

我希望能夠導入我的設置,因爲我發送了幾個月到達該狀態。

我曾經遇到過同樣的問題,但是在將Boot的啓動cli版本從Boot 1.5.4.RELEASE更改爲Boot 1.5.8.RELEASE之後,它對我來說工作正常。
從 下載release/org/springframework/boot/spring-boot-cli

將其保存到本地文件夾並添加到此處。清理並重建項目。就這樣 !
