本文介绍了一种常见的MyBatis与Spring整合时出现的AbstractMethodError异常，并提供了具体的解决方案。异常出现在尝试通过浏览器访问学生信息列表时，原因是使用的MyBatis版本过高。解决方法是将MyBatis版本调低。
1.开发工具:idea+java8+ssm
2.浏览器输入 http://localhost:8080/test/student/findAll.do
3.浏览器报错显示:

4.1搜索加黑倾斜的文字:Message Handler dispatch failed; nested exception is java.lang.AbstractMethodError
4.2错误原因:搜索加黑倾斜的文字,显示pom.xml使用了较高版本的mybatis
5.解决方案:把mybatis版本调低就行!
