47.5. 예제

다음 주석이 있는 java 8080이 있다고 가정합니다.

Car.java

public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 5, max = 14, groups = OptionalChecks.class)
    private String licensePlate;

    // getter and setter
}

public class Car {

    @NotNull
    private String manufacturer;

    @NotNull
    @Size(min = 5, max = 14, groups = OptionalChecks.class)
    private String licensePlate;

    // getter and setter
}

사용자 정의 검증 그룹에 대한 인터페이스 정의

OptionalChecks.java

public interface OptionalChecks {
}

public interface OptionalChecks {
}

다음 Camel 경로를 사용하면 속성 manufacturer 및 licensePlate에 대한 @NotNull 제약 조건만 검증됩니다(Camel은 기본 그룹 javax.validation.groups.Default)을 사용합니다.

from("direct:start")
.to("bean-validator://x")
.to("mock:end")

from("direct:start")
.to("bean-validator://x")
.to("mock:end")

OptionalChecks 그룹에서 제약 조건을 확인하려면 다음과 같이 경로를 정의해야 합니다.

from("direct:start")
.to("bean-validator://x?group=OptionalChecks")
.to("mock:end")

from("direct:start")
.to("bean-validator://x?group=OptionalChecks")
.to("mock:end")

두 그룹의 제약 조건을 확인하려면 먼저 새 인터페이스를 정의해야 합니다.

AllChecks.java

@GroupSequence({Default.class, OptionalChecks.class})
public interface AllChecks {
}

@GroupSequence({Default.class, OptionalChecks.class})
public interface AllChecks {
}

그러면 경로 정의가 다음과 같아야 합니다.

from("direct:start")
.to("bean-validator://x?group=AllChecks")
.to("mock:end")

from("direct:start")
.to("bean-validator://x?group=AllChecks")
.to("mock:end")

그리고 자신의 메시지 보간, traversable resolver 및 constraint validator 팩토리를 제공해야 하는 경우 이와 같은 경로를 작성해야 합니다.

<bean id="myMessageInterpolator" class="my.ConstraintValidatorFactory" />
<bean id="myTraversableResolver" class="my.TraversableResolver" />
<bean id="myConstraintValidatorFactory" class="my.ConstraintValidatorFactory" />

from("direct:start")
.to("bean-validator://x?group=AllChecks&messageInterpolator=#myMessageInterpolator
&traversableResolver=#myTraversableResolver&constraintValidatorFactory=#myConstraintValidatorFactory")
.to("mock:end")

<bean id="myMessageInterpolator" class="my.ConstraintValidatorFactory" />
<bean id="myTraversableResolver" class="my.TraversableResolver" />
<bean id="myConstraintValidatorFactory" class="my.ConstraintValidatorFactory" />

from("direct:start")
.to("bean-validator://x?group=AllChecks&messageInterpolator=#myMessageInterpolator
&traversableResolver=#myTraversableResolver&constraintValidatorFactory=#myConstraintValidatorFactory")
.to("mock:end")

제약 조건을 Java 주석이 아닌 XML로 설명할 수도 있습니다. 이 경우 다음과 같은 META-INF/validation.xml 파일을 제공해야 합니다.

validation.xml

다음은 OrderedChecks 가 https://github.com/apache/camel/blob/master/components/camel-bean-validator/src/test/java/org/apache/camel/component/bean/validator/OrderedChecks.java일 수 있는 예제 경로 정의의 XML 구문입니다.

본문에는 유효성을 검사할 클래스의 인스턴스가 포함되어야 합니다.
