Invalid bound statement (not found): com.itheima.mapper.StudentMapper.selectAll

Invalid bound statement (not found): com.itheima.mapper.StudentMapper.selectAll错误通常是由于mybatis的配置问题导致的。根据引用、引用和引用中的信息，我可以给出以下解决方案:

1. 确保mapper接口和xml文件对应。检查StudentMapper接口和对应的StudentMapper.xml文件是否存在，并且它们的命名和路径是否正确匹配。

2. 检查xml文件的命名空间是否与接口包名一致。确保StudentMapper.xml文件中的namespace与StudentMapper接口的包名一致。

3. 如果项目是maven项目，需要在pom.xml文件中添加resources配置。这可以确保maven编译时将xml文件包含在编译路径中。根据引用中的提示，可以在pom.xml文件的resources配置中添加<include>**/*.xml</include>。

4. 在Java的配置文件中创建包，并将mapper映射文件放入其中。根据引用的建议，在配置文件中创建一个包，包名与StudentMapper接口的包名一致，然后将StudentMapper.xml文件放入该包中。

通过检查以上几点，您应该能够解决Invalid bound statement (not found)错误，并成功调用com.itheima.mapper.StudentMapper.selectAll方法。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
