在开发excle的通用导入导出功能,用到注解,报如下错误,包导入不进来
RetentionPolicy cannot be resolved to a variable
ElementType cannot be resolved to a variable
@Retention和@Target都能导入进来,没办法只能手动导入包了
import java.lang.annotation.*
或
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.ElementType;
这样,RetentionPolicy/ElementType cannot be resolved to a variable问题就解决了
