spring combine two validation annotations in one

You can add

@ConstraintComposition

Who is by default at AND and if one day you want @NotNull or @Size You add

@ConstraintComposition(OR)

Edit : this is an exemple who combine @Pattern(regexp = "[a-z]") and @Size(min = 2, max = 3)

@ConstraintComposition(OR)
@Pattern(regexp = "[a-z]")
@Size(min = 2, max = 3)
@ReportAsSingleViolation
@Target({ METHOD, FIELD })
@Retention(RUNTIME)
@Constraint(validatedBy = { })
public @interface PatternOrSize {
    String message() default "";

 Class<?>[] groups() default { };

 Class<? extends Payload>[] payload() default { };

}

This is a bit late, but technique of combining validation annotations described in

https://docs.jboss.org/hibernate/stable/validator/reference/en-US/html_single/?v=5.4#section-constraint-composition

Maybe it was not available, at the time of writing, but solution is following

@NotNull
@Size(min=4)
@Target({ METHOD, FIELD, ANNOTATION_TYPE })
@Retention(RUNTIME)
@Constraint(validatedBy = { })
@Documented
public @interface JPasswordConstraint {
    String message() default "Password is invalid";
    Class<?>[] groups() default { };
    Class<? extends Payload>[] payload() default { };
 }
