객체의 유효성을 확인하기 위한 주요 인터페이스 및 클래스
1. Installation
OpenJDK 11 이상
1.1. maven
<dependencies>
<dependency>
<groupId>io.github.cube8540</groupId>
<artifactId>validator-core</artifactId>
<version>1.3.0-RELEASE</version>
</dependency>
</dependencies>
1.2. Gradle
dependencies {
compile 'io.github.cube8540:validator-core:1.3.0-RELEASE'
}
2. Getting Started
2.1. Validator + ValidationRule 을 이용한 객체 유효성 검사 방법
// 유효성 검사 규칙을 구현
public class YourValidationRule implements ValidationRule<YourClass> {
@Override
public boolean isValid(YourClass object) {
// 유효성 검사 결과 반환 (유효할시 true 유효하지 않을시 false)
}
@Override
public ValidationError error() {
return new ValidationError(PROPERTY, ERROR_MESSAGE);
}
}
// 유효성 검사후 검사 결과를 얻기
ValidationResult result = Validator.of(yourObject)
.registerRule(new YourValidationRule())
.getResult();
2.2. ValidationSpecification 구현 방법
// AbstractValidationSpecification 을 상속받아 구현한다.
public class YourValidationSpecification extends AbstractValidationSpecification<YourClass> {
@Override
public boolean isValid(YourClass object) {
// 유효성 검사 결과 반환 (유효할시 true 유효하지 않을시 false)
}
}
// 유효성 검사 명세서를 이용하여 규칙을 구현
public class YourValidationRule implements ValidationRule<YourClass> {
private final Specification<YourClass> specification;
pubic YourValidationRule(Specification<YourClass> specification) {
this.specification = specification;
}
@Override
public boolean isValid(YourClass object) {
return specification.isValid(object);
}
@Override
public ValidationError error() {
return new ValidationError(PROPERTY, ERROR_MESSAGE);
}
}
// 유효성 검사 명세서를 조합
ValidationRule<YourClass> specification = new YourValidationSpecification1()
.and(YourValidationSpecification2())
.or(YourValidationSpecification3())
...;
// 유효성 검사후 검사 결과를 얻기
ValidationResult result = Validator.of(yourObject)
.registerRule(new YourValidationRule(specification))
.getResult();
// ValidationResult 형식이 아닌 Boolean 형식으로 결과값 반환
boolean result = specification.isValid(yourObject);
2.3. Operator 이용
// 가장 기본적인 Operator 생성
Operator<YourClassType> operator = new ValidationOperator<YourClassType>(Operator.OperatorType.AND)
.addOperand(target -> ...return true/false)
.addOperand(target -> ...return true/false)
.....;
// 결과 얻기
boolean result = operator.isValid(yourObject);
