bean的初始化失败; 嵌套异常是org.springframework.beans

Question

我将我的模型类保存在com.anand.model.Employee.java中,正确地我在sdnext-servlet.xml中提到了annotatedClasses.但我仍然得到错误.请帮我解决这个问题.

sdnext-servlet.xml中

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses">
            <list>
                <value>com.anand.model.Employee</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>             
            </props>
        </property>
    </bean>

模型类:Employee.java

package com.anand.model;

    }

    public void setEmpAddress(String empAddress) {

    }

    public void setEmpAge(Integer empAge) {

Answer 1

这是您所做的替代方案.尝试在配置中替换annotatedClasses以下元素的那个并在之后清理构建工作区+重新启动服务器.

<property name="packagesToScan">
    <list>
        <value>com.anand.model</value>           
    </list>
</property>
