Mapped Statements collection does not contain value

最近一个项目在启动的时候，当需要访问service时，报错了，出现如下错误:

分析：我们的service不应该跟mybatis有什么关系，而异常中说我们的servcie不符合mybatis的映射规则。

所以应该是spring和mybatis整合的时候，把我们的service也当成普通的mapper扫描进去了。

核查配置文件发现（改配置扫描了项目上所有的包，需要缩小范围）：

<!-- spring与mybatis整合配置，扫描所有dao -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage="com.xxx.newportal."
          p:sqlSessionFactoryBeanName="sqlSessionFactory"/>

改为如下即可

<!-- spring与mybatis整合配置，扫描所有dao -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer" p:basePackage="com.xxxx.newportal.certtrustweb.dao"
          p:sqlSessionFactoryBeanName="sqlSessionFactory"/>
严重: Servlet.service() for servlet [dispatcher] in context with path [/certtrustweb] threw exception [Request processing failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.xxx.xxx.certtrustweb.service.MakeCertService.makeCertByFisrtTime] with root cause
