MyBatis错误--Invalid bound statement (not found)

今天在开发项目的时候使用MyBatis发生错误：Invalid bound statement (not found)

具体错误信息：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jobTaskServiceImpl': Invocation of init method failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.mkit.task.manager.dao.ScheduleJobMapper.getAll

通过分析找到了问题的原因。我出现这个错误的主要原因是因为dao层和Mapper.xml是从别的项目中copy过来的，然后这些属性值都没有做更改，所以报这样的错误。

解决：

1.首先查看spring-mybatis.xml文件中，对于dao层的class扫描路径是否正确。

2.检查Mapper.xml文件中namespace属性值是否正确

3.检查Mapper.xml文件中resultMap中type属性值是否正确

<mapper namespace="com.mkit.task.manager.dao.ScheduleJobMapper">
    <resultMap id="BaseResultMap" type="com.mkit.task.manager.pojo.ScheduleJob">
        <id column="job_id" property="jobId" jdbcType="BIGINT" />
        <result column="create_time" property="createTime" jdbcType="TIMESTAMP" />
        <result column="update_time" property="updateTime" jdbcType="TIMESTAMP" />
        <result column="job_name" property="jobName" jdbcType="VARCHAR" />
        <result column="job_group" property="jobGroup" jdbcType="VARCHAR" />
        <result column="job_status" property="jobStatus" jdbcType="VARCHAR" />
        <result column="cron_expression" property="cronExpression"
            jdbcType="VARCHAR" />
        <result column="description" property="description" jdbcType="VARCHAR" />
        <result column="bean_class" property="beanClass" jdbcType="VARCHAR" />
        <result column="is_concurrent" property="isConcurrent"
            jdbcType="VARCHAR" />
        <result column="spring_id" property="springId" jdbcType="VARCHAR" />
        <result column="method_name" property="methodName" jdbcType="VARCHAR" />
    </resultMap>
