Question

我的应用程序在Exception下面，对于Spring中的bean验证，我使用的是Spring4.0.2版本。

我正在使用weblogic11g应用程序服务器

javax.validation.ValidationException：调用TraversableResolver.isReachable（）引发异常 at org.hibernate.validator.engine.ValidatorImpl.isValidationRequired（ValidatorImpl.java:773） at org.hibernate.validator.engine.ValidatorImpl.validateConstraint（ValidatorImpl.java:331） at org.hibernate.validator.engine.ValidatorImpl.validateConstraintsForRedefinedDefaultGroup（ValidatorImpl.java:278） at org.hibernate.validator.engine.ValidatorImpl.validateConstraintsForCurrentGroup（ValidatorImpl.java:260） at org.hibernate.validator.engine.ValidatorImpl.validateInContext（ValidatorImpl.java:213）截断。查看日志文件以获取完整的堆栈跟踪引发者：javax.persistence.PersistenceException：无法从META-INF / services加载提供程序 at javax.persistence.spi.PersistenceProviderResolverHolder $ DefaultPersistenceProviderResolver.getPersistenceProviders（PersistenceProviderResolverHolder.java:121）在javax.persistence.Persistence $ PersistenceUtilImpl.isLoaded（Persistence.java:278）在org.hibernate.validator.engine.resolver.JPATraversableResolver.isReachable（JPATraversableResolver.java:33） at org.hibernate.validator.engine.resolver.DefaultTraversableResolver.isReachable（DefaultTraversableResolver.java:112） at org.hibernate.validator.engine.resolver.SingleThreadCachedTraversableResolver.isReachable（SingleThreadCachedTraversableResolver.java:47）截断。查看日志文件以获取完整的堆栈跟踪引发者：java.lang.ClassCastException：org.apache.openjpa.persistence.PersistenceProviderImpl无法强制转换为javax.persistence.spi.PersistenceProvider at javax.persistence.spi.PersistenceProviderResolverHolder $ DefaultPersistenceProviderResolver.getPersistenceProviders（PersistenceProviderResolverHolder.java:110）在javax.persistence.Persistence $ PersistenceUtilImpl.isLoaded（Persistence.java:278）在org.hibernate.validator.engine.resolver.JPATraversableResolver.isReachable（JPATraversableResolver.java:33） at org.hibernate.validator.engine.resolver.DefaultTraversableResolver.isReachable（DefaultTraversableResolver.java:112） at org.hibernate.validator.engine.resolver.SingleThreadCachedTraversableResolver.isReachable（SingleThreadCachedTraversableResolver.java:47）截断。请参阅日志文件以获取完整的堆栈跟踪

这是我的POJO课程

import java.util.Date;

import javax.validation.constraints.Digits;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Pattern;

import org.hibernate.validator.constraints.Length;
import org.hibernate.validator.constraints.NotEmpty;


public class TestVO extends BaseVO {

        private static final long serialVersionUID = 1L;

        @Length(max=18)
        @NotNull
        @NotEmpty
        @Pattern(regexp = "[a-zA-Z0-9]*")
        private String Id;

                public String getId() {
                return Id;
        }

        public void setId(String Id) {
                this.Id = Id;
        }


}

这是我的验证员类

import javax.validation.ConstraintViolation;
import javax.validation.Validator;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class DataValidator {

        @Autowired(required = true)
        private Validator validator;

        public Set<ConstraintViolation<Object>>  validate(Object tvo) {
                return this.validator.validate(tvo);
        }
}

这是我的控制器类，我正在尝试验证我的POJO

@Autowired
private DataValidator dValidator;

TestVO testVO = testBO.getTest(id);
Set<ConstraintViolation<Object>> violations = this.dValidator.validate(testVO);

我已使用以下验证器

更新了application-context.xml

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />

I have below Jar's in place in my WEB-INF/lib

hibernate-validator-4.0.1.GA.jar
validation-api-1.0.0.GA.jar
j2ee.jar
javax.persistence_1.0.0.0_1-0-2.jar
commons-logging-1.1.1.jar

任何帮助都非常感谢。

此问题通常发生在加载同名类但来自不同类加载器的类冲突中。我建议你检查任何重复的持久性jar文件（在你的情况下是javax.persistence_1.0.0.0_1-0-2.jar）并删除它们（它们）

Answer 2

如果您正在使用某些Hibernate字节码增强配置，您也可能会遇到此异常。见https://hibernate.atlassian.net/browse/HHH-11294
