I am applying multiple validations on path variable
@PathVariable(name = "id")
@NotBlank(message = "Missing required field")
@Size(min = 1, max = 3, message = "Invalid input size")
String idNow, when I am sending empty string in path param then I am getting both messages because both validations are failing.
For my param id, I want both validations but it should not throw both error messages at a time when I am sending empty string.
I want it to throw only
"Missing required field"
and not both.

NotBlank是NotNull和NotEmpty验证的两个功能的组合。因此，当绑定的pathVariable为null和empty时，@NotBlank都将触发。因为您已经有
@Size(min = 1, max = 3, message = "Invalid input size")，所以您已经在检查not empty。如果pathVariable是empty字串，这个注解会与@NotBlank同时触发。因此，当它是
null时，您只需要一个不同的约束验证，这样强制约束的两个注解就不会相互覆盖。作为解决方案，您可以将
@NotBlank替换为@NotNull。
