SpringMVC 使用JSR-303进行校验Bean Validation------组合验证注解

@Target({ FIELD})
@Retention(RUNTIME)
@Documented
@NotNull(message = "{user.name.null}")
@Length(min = 5, max = 20, message = "{user.name.length.illegal}")
@Pattern(regexp = "[a-zA-Z]{5,20}", message = "{user.name.length.illegal}")
@Constraint(validatedBy = { })
public @interface Composition {
String message() default "";
Class<?>[] groups() default { };
Class<? extends Payload>[] payload() default { };
}

@Composition()
private String name;
