通常遇到这种问题的时候，就应该想到，是 xxxMapper.xml 里面缺少对应的定义;

比如我这里提到的是 User.pageSelect，那么就应该对应着 UserMapper.xml；

就比如缺少以下这样的定义：

<select id="pageSelect" resultMap="userResult">
    		SELECT
    		<include refid="commonColumns" />
    		FROM `user`
    		<include refid="dynamicWhere" />
    
    		<if test="@Ognl@isNotEmpty(sortColumns)">
    			ORDER BY ${sortColumns}
    		</if>
    	</select>

就是缺少一个 id 为 pageSelect 的 select 标签。

但是我今天遇到的情况不是这样子的！

在研究一个问题： [SpringBoot druid配置datasource启动初始化数据库连接][SpringBoot druid_datasource]

定义了一个常量：

static final String MAPPER_LOCATION = "classpath:com/wanyu/*/mapping/*Mapper.xml ";

就因为这个常量，产生了错误，你看出来问题在哪里了吗？

因为最后多了一个空格，这扩展名是 xml空格的文件哪里找的到，因此就产生了错误。

这又是复制粘贴惹的祸祸，这个配置在 application.properties 文件中是没有问题的（应该是，这里先不花时间去确定了），

但是在这里出现问题了。

对于代码、配置的复制粘贴，一定要注意！
