When it comes to validating user input in Spring MVC, there are a few different approaches that you can take. One option is to use the @Min and @Max annotations to specify the minimum and maximum allowed values for a given field. For example, if you wanted to ensure that a user's input was between 1 and 10, you would annotate the field as follows:  @Min(1)
@Max(10)
int value;  Alternatively, you could also use the @Range annotation, which allows you to specify both the minimum and maximum values in a single annotation. For example:  @Range(min=1, max=10)
int value;  If neither of these annotations meets your needs, you can also create a custom validator by implementing the org.springframework.validation.Validator interface. This gives you full control over how input is validated, although it requires more code than either of the other two options.
