spring - 什么是全局错误(在 Spring 验证中)？

Question

我正在检查 Spring 验证 Errors ( BindingResult ) 界面。它提到了与字段错误相反的全局错误。什么是全局错误？

Answer 1

FieldError ( javadoc )

通过 rejectValue 注册( javadoc )

附加到一个字段
例子:

errors.rejectValue("name", "name.empty", "cannot be empty")`

ObjectError (全局错误)( javadoc )

通过 reject 注册( javadoc )

未附加到特定字段(多字段或与字段无关)
例子:

errors.reject("password.mismatch", "Password doesn't match confirm password")
errors.reject("optimistic.out-out-date", "This page has been saved in the meantime. Reload it and start editing it again")
