【问题描述】:
我正在尝试使用执行器。问题是当我使用版本 2 或更高版本时,服务器开始出现故障。如果我使用的版本 1 小于 2 服务器可以正常启动,但是我没有得到 /actuator 等端点。请帮忙。真的卡在里面了。

【问题讨论】:
-
你读过migration guide吗?并注意:由于您已设置
,您不再需要为 spring boot 启动器依赖项指定版本。 -
如果你使用的是parent,设置actuator的版本是错误的。此外,微米核心等已经由父级处理......所以不需要版本定义。
-
是的,但如果我没有提到版本应用程序不运行。这是由于增加了对执行器的依赖。如果我提到带有执行器的 1.x.x 版本,应用程序会运行但不会获得执行器端点。
-
不要使用一个版本,或者至少不要混合一个框架的版本。修复你得到的异常,将它与来自不同版本的 jar 混合并不能解决问题,但会导致其他问题。所以不是只显示版本,而是显示你得到的异常。
-
我已经添加了例外。请帮忙
