mybatis 抛出 Mapped Statements collection does not contain value for 异常
来源:互联网 发布:家具有味怎么办知乎 编辑:程序博客网 时间:2024/06/04 18:54
对mybatis不是很熟,最近写接口的时候,一直报Mapped Statements collection does not contain value for异常,最后发现是接口调用的xml里没有所写方法,方法写到了弄一个备份文件里面了。
错误原因有几种:
1、mapper.xml中没有加入namespace2、mapper.xml中的方法和接口mapper的方法不对应
3、mapper.xml没有加入到mybatis-config.xml中(即总的配置文件),例外:配置了mapper文件的包路径的除外
4、mapper.xml文件名和所写的mapper名称不相同。
