The javaee dependencies includes the javax.validation packages,

which in turn trigger the automatic registration of a JSR-303 bean validation.

But the javaee only has the API not an implementation for it.

Either add an implementation or don't use the fat javaee jar as a dependency.

Also it isn't an error it is a debug message, telling you a provider cannot be found,

 your application should start regardless of that.

javaee依赖关系包括javax.validation程序包，

从而触发JSR-303 Bean验证的自动注册。

但是，javaee只有API不是一个实现。

 添加一个实现或者不要使用javaee jar作为依赖。

 此外，它不是一个错误，它是一个调试消息，告诉您不能找到提供程序，您的应用程序应该开始，可以忽略这个提示。
