Invalid bound statement (not found) 异常原因

org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [dispatcherServlet] in context with path [/zc-beauty2]   
threw exception [Request processing failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):  
 com.zc.beauty.dao.ICaptchaMapper.savePhoneCode] with root cause  
 org.apache.ibatis.binding.BindingException: Invalid bound statement (not found):

原因如下：

1、没有加载mapper文件：

<mappers>  
        <mapper resource="mappers/CaptchaMapper.xml" />  
</mappers>

<!-- 这里namespace必须是接口的路径，不然要运行的时候要报错 “is not known to the MapperRegistry”-->  
<mapper namespace="com.zc.beauty.dao.ICaptchaMapper">

<bean id="CaptchaMapper" class="org.mybatis.spring.mapper.MapperFactoryBean" >  
       <property name="sqlSessionFactory" ref="SqlSessionFactory" />  
       <property name="mapperInterface" value="com.zc.beauty.dao.ICaptchaMapper" />  
   </bean>

<!-- 这里的id必须和接口中的方法名相同，不然运行的时候也要报错 -->  
   <insert id="savePhoneCode" parameterType="com.zc.beauty.model.PhoneCaptcha">  
       insert into phone_captcha(u_phone, c_phonecode, c_sendtime) values(#{u_phone}, #{c_phonecode}, #{c_sendtime})  
   </insert>
