Answer 1

spring-mybatis.xml
: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.apache.ibatis.session.Configuration.setDatabaseId(Ljava/lang/String;)V

org.apache.ibatis.session.Configuration.setDatabaseId 找不到这个方法，你jar包换个版本试试吧

追问

已经换过啦是最新的版本。可是还是报这个错误啊。不知道是注解的原因还是spring-mybatis.xml的原因。还是没找出来啊 求助啊 大哥

追答

开发中不是最新版的就是最好的。

试试换到低版本吧，你会反编译么？

如果会的反编译一下，看看里面有没有这个方法就知道jar包版本对不对了
