({ElementType.FIELD, ElementType.METHOD})
(RetentionPolicy.RUNTIME)
(validatedBy=MinValidator.)
Min {
value() ;
{};
Payload>[] payload() {};
MinValidator ConstraintValidator
minValue;
initialize(Min min) {
isValid(Integer value, ConstraintValidatorContext arg1) {
value >= minValue;
User {
age;
(value=https://www.yisu.com/zixun/, message=)
getAge() {
age;
setAge( age) {
.age = age;
二、group校验
public class Student implements Serializable {
private static final long serialVersionUID =, 1 l;
@NotBlank (message =, "名称不能为空”,,groups =, {, First.class })
private String 名称;
@NotBlank (message =,”年龄不能为空”,,groups =, {, Second.class })
private String 年龄;
,,,,,,,…省略get 集方法
}
public @interface First {
}
public @interface Second {
}
public static void main (String [], args) {,
,,,,Student Student =, new 学生(),,
,,,,ValidatorFactory vf =, Validation.buildDefaultValidatorFactory ();
,,,,Validator Validator =, vf.getValidator (),,
,,,,Set祝辞,set =, validator.validate(学生,First.class);,
,,,,for (ConstraintViolation
自定义@ interface及组织校验
