当我在类路径上声明validation.xml 文件时，Glassfish4 抛出异常

Question

我尝试为@NotNull 约束声明一个自定义验证器，Glassfish4 在查找/META-INF/validation.xml 时抛出此异常。如果我省略此文件，项目工作正常。

这是约束 xml 文件

<constraint-definition annotation="org.hibernate.validator.constraints.NotNull">
    <validated-by include-existing-validators="true">
        <value>es.project.validator.customConstraint.NotEmptyValidator</value>
    </validated-by>
</constraint-definition>

和validation.xml

<validation-config
xmlns="http://jboss.org/xml/ns/javax/validation/configuration"
xsi:schemaLocation="http://jboss.org/xml/ns/javax/validation/configuration validation-configuration-1.0.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<constraint-mapping>META-INF/validation/mapping.xml</constraint-mapping>

                               +----------\mapping.xml

验证码

public class NotEmptyValidator implements ConstraintValidator<NotNull,Object> {

}

@Override
public boolean isValid(Object value, ConstraintValidatorContext context) {


    if(value.toString().isEmpty()){
        ...........
                    ...........
                    ...........
    }

    return true;
}

}

Answer 1

更新：

在您的情况下，问题是您引用了org.hibernate.validator.constraints.NotNull，但您可能想要javax.validation.constraints.NotNull。你的mapping.xml 应该是这样的：

<constraint-definition annotation="javax.validation.constraints.NotNull">
    <validated-by include-existing-validators="true">
        <value>es.project.validator.customConstraint.NotEmptyValidator</value>
    </validated-by>
</constraint-definition>

您的配置的其他部分应该是正确的。 这应该可以在不定义注释的情况下工作。

如果您想在不替换/重用现有验证器的情况下实现自定义 Bean Validation 验证器，则需要注释定义并且必须实现 ConstraintValidator interface。这是一个例子：

注释：

import java.lang.annotation.Documented;  
import java.lang.annotation.ElementType;  
import java.lang.annotation.Retention;  
import java.lang.annotation.RetentionPolicy;  
import java.lang.annotation.Target;  
import javax.validation.Constraint;  

@Documented  
@Retention(RetentionPolicy.RUNTIME)  
@Target({ElementType.METHOD,ElementType.FIELD,ElementType.CONSTRUCTOR,ElementType.PARAMETER,ElementType.ANNOTATION_TYPE})  
@Constraint(validatedBy=NotNulllValidator.class)  
public @interface NotNull {  

   String message();  
   Class[] groups() default {};  
   Class[] payload() default {};  
}

验证者：

import javax.validation.ConstraintValidator;
import javax.validation.ConstraintValidatorContext;

public class NotNulllValidator implements ConstraintValidator<NotNull, String> {

    @Override
    public void initialize(NotNull email) {}

    @Override
    public boolean isValid(String email, ConstraintValidatorContext context) {
        return true;
    }
}

映射应该与您已有的一样。
