Invalid bound statement (not found) 异常原因

mybatis报错如下：

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>

2、接口路径问题：

<!-- 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">

3、没有映射：

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

4、DAO层方法名和xml中的id不同

<!-- 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>

5、返回类型resultMap在xml中未声明

<resultMap id="RecsortChnResultMap" type="com.caissa.erp.caissafip.domain.basic.recsortchnconfig.po.RecsortChnConfigVo" >    <id column="DBID" property="dbid" jdbcType="CHAR" />    <result column="FK_RECCHN_DBID" property="fkRecchnDbid" jdbcType="CHAR" />    <result column="UPDATEDEPTNAME" property="updatedeptname" jdbcType="VARCHAR" />  </resultMap><select id="selectChnRectypeByConfigDbid" resultMap="ChnRectypeResultMap" parameterType="java.lang.String">SELECT CRR.DBID, recsort.RECSORTNAME,  chn.CHNNAME,  rectype.RECTYPENAME,CRR.FK_CONFIG_DBID,CRR.FK_RECTYPE_DBID,rcconfig.FK_RECCHN_DBID,rcconfig.FK_RECSORT_DBID,rcconfig.ISRECEIVABLE,rcconfig.RECEIVABLECOMPANYCODE,rcconfig.RECEIVABLECOMPANYNAMEFROM FI_BS_CHN_RECTYPE_REF CRR LEFT JOIN FI_BS_RECSORT_CHN_CONFIG rcconfig on CRR.FK_CONFIG_DBID = rcconfig.dbidleft join FI_DC_RECEIVESORT recsort on recsort.dbid = rcconfig.FK_RECSORT_DBID and recsort.delflag = '1'left join FI_BS_CHN chn on chn.dbid = rcconfig.FK_RECCHN_DBID and chn.delflag = '1' left join FI_DC_RECEIVETYPE rectype on rectype.dbid = crr.FK_RECTYPE_DBID and rectype.delflag = '1'WHERE RCCONFIG.DELFLAG = '1' AND CRR.DELFLAG = '1'AND RCCONFIG.DBID = #{fkConfigDbid, jdbcType=VARCHAR}  </select>
