上边是报的错,开头关键和结尾两处异常信息,查询一些相似的大多都说是因为未引入依赖问题及与实体类映射出现问题

我这边就是属于与实体类映射问题,我的一个mapper的xml文件原本没有问题但是缺少与实体映射的配置,可以运行.后边其他同事在那个xml中添加了一段与实体映射的内容

<resultMap id="BaseResultMap" type="com.jsh.erp.datasource2.model.PurchaseStockin">

加了也不会有问题,关键是他把需要大写的字母小写了,导致找不到那个实体,所以出现一系列问题

如果你有这种问题可以从上边加粗的两点出发 ,xml文件中只要写的路径对的按Ctrl是可以跳转到对应的实体的
