解决方案 »

  1.   

    Bean property 'sqlMapClient' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter? 看看setter方法
      

  2.   

    添加：
    <bean id="sqlMapClientTemplate"
    class="org.springframework.orm.ibatis.SqlMapClientTemplate">
    <property name="sqlMapClient">
    <ref bean="sqlMapClient" />
    </property>
    </bean>
    修改：
    <bean id="productDao" class="com.jlh.dao.AddDAOImpl"> 
        <property name="sqlMapClientTemplate">
        <ref bean="sqlMapClientTemplate" />
       </property> 
    </bean>
