我正在将 Spring 与 Hibernate 集成。但是，当我运行该应用程序时，出现如下错误:

Error creating bean with name 'sessionFactory' defined in class path resource [resources/spring.xml]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Unable to get the default Bean Validation factory

我的 spring.xml 看起来像:

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

    <property name="password" value="3encult" />
    <property name="username" value="3encult" />
</bean>

<bean id="sessionFactory"
    class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="myDataSource" />
    <property name="mappingResources">

    <property name="hibernateProperties">

</bean>

<bean id="myUserDAO" class="main.java.com.gwt.app.server.User">
    <property name="sesionFactory" ref="sessionFactory" />
</bean>
</beans>

类User中的注入(inject)是:

ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"resources/spring.xml"});

public void setSesionFactory(SessionFactory sesionFactory){
    this.sesionFactory = sesionFactory;
    this.sesion = this.sesionFactory.openSession();
}

堆栈跟踪是:

构建路径包含以下库:

hibernate3.jar
org.springframework.aop-3.1.0.M1.jar
org.springframework.asm-3.1.0.M1.jar
org.springframework.aspects-3.1.0.M1.jar
org.springframework.beans-3.1.0.M1.jar
org.springframework.context-3.1.0.M1.jar
org.springframework.context.support-3.1.0.M1.jar
org.springframework.core-3.1.0.M1.jar
org.springframework.expression-3.1.0.M1.jar
org.springframework.instrument-3.1.0.M1.jar
org.springframework.instrument.tomcat-3.1.0.M1.jar
org.springframework.jdbc-3.1.0.M1.jar
org.springframework.jms-3.1.0.M1.jar
org.springframework.orm-3.1.0.M1.jar
org.springframework.oxm-3.1.0.M1.jar
org.springframework.transaction-3.1.0.M1.jar

我没有使用验证。这是不包含验证 jar 的原因。

我不知道会发生什么，我希望有人能帮助我。

谢谢!

最佳答案

Hibernate 引发异常:throw new HibernateException( "Unable to get the default Bean Validation factory", e); 如果它无法访问 Bean Validation Framework (BeanValidationActivator)。

所以我猜问题是缺少验证 jar 。

对于 Maven:

    <dependency>
        <groupId>javax.validation</groupId>
        <artifactId>validation-api</artifactId>
        <version>1.0.0.GA</version>
    </dependency>
    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-validator</artifactId>
        <version>4.0.2.GA</version>
    </dependency>
