Question

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'studentdao' defined in URL [file:/E:/资料/apache-tomcat-6.0.29/webapps/firstibatis/WEB-INF/classes/spring/applicationContext-jdbc.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'driverClassName' of bean class [dao.impl.StudentDaoImpl]: Bean property 'driverClassName' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

xml配置文件如下：


 <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
        <property name="dataSource" ref="dataSource"/>  
        </bean>  

       <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">  

        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>  

        <property name="url" value="jdbc:mysql://127.0.0.1/student"/>  

        <property name="username" value="root"/>  

        <property name="password" value="root"/>  

    </bean>  

<!--配置哪些方法,什么情况下需要回滚-->


tx:attributes

<!--当代理的service层中的方法抛出异常的时候才回滚,必须加rollback-for参数-->





<!--除了上面标识的方法,其他方法全是只读方法 -->


/tx:attributes

/tx:advice

<!-- 配置哪些类的方法需要进行事务管理 -->







/aop:config

<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">  
       <property name="configLocation"><value>classpath:config/jdbc/sqlMapConfig.xml</value></property>

    studentdaoimpl

      public class StudentDaoImpl   extends SqlMapClientDaoSupport implements StudentDao{

@Override

    // TODO Auto-generated method stub
    return null;

}

@Override

}

Answer 1

StudentDaoImpl 里面没有sqlMapClient 的定义
