spring - Bean 属性 'sessionFactory' 不可写或具有无效的设置方法。

Question

这是我的实用程序 java 文件:

public class HibernateUtil {

    private static SessionFactory sessionFactory  = null;

    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public static void setSessionFactory(SessionFactory sessionFactory) {
        HibernateUtil.sessionFactory = sessionFactory;
    }
}

Spring-servlet.xml:

    <bean id="HibernateUtil" class="com.chrysler.Utilities.HibernateUtil">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation">
            <value>/WEB-INF/hibernate.cfg.xml</value>
        </property>
    </bean>

当我运行它时，出现以下错误:

org.springframework.beans.NotWritablePropertyException: Invalid property 'sessionFactory' of bean class [com.chrysler.Utilities.HibernateUtil]: Bean property 'sessionFactory' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

Answer 1

使 sessionFactory 的访问器方法成为非静态的
