invalid bound statement (not found)

按字面翻译是invalid bound statement (not found)，指的是找不到Mapper文件

确保你的项目存在相应的Mapper文件后，在mybatis-config.xml中更改设置，将XXXMapper.xml添加进…中

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>
<!-- 延迟加载、懒加载，作用于属性和对象域上面 -->
<setting name="lazyLoadingEnabled" value="true" />
<!-- 是否立即初始化属性或者对象域 -->
<setting name="aggressiveLazyLoading" value="false" />
</settings>
<mappers>
<mapper resource="XxxxMapper.xml"/>
</mappers>
</configuration>

重启tomcat即可
