特殊问题记录(已解决)Servlet.service() for servlet [dispatcherServlet] in context with path [] th

mapper

xml错误信息:Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.binding.BindingException: Parameter 'ids' not found. Available parameters are [arg0, collection, list]] with root cause

处理方法:

mapper中接口添加注解@Param("ids")

  void delete(@Param("ids") List<Integer> ids);
