今天去写项目，突然发现SpringBoot的配置文件下方出现了波浪线。指针指上去后显示。 在网上查阅了一些资料，说是SpringBoot的配置文件不是小绿叶。 但是我这边配置文件也是小绿叶，新建工程也是同样的问题。 有没有大佬知道是怎么回事啊？谢谢！！！

springboot使用mybatis去查询Oracle数据库，想取值打印出来，但打不出来。传参数去查询、写死sql查询，都打不出来。但是传参数去查条数可以打出 条数值。 试过 把resultType 改成 java.lang.String、string、String, 都不行 service的实现类： mapper: 查条数有值： 打断点 没显示值： 数据库有值

我跟着《Java Web从入门到精通》学习struts，在idea环境下配置struts.xml时提示cannot resolve symbol 'user_add.jsp'，不知道如何解决，请教一下大佬们。 后来新创了个test项目重做了一遍，在打同一行时依然出现了该问题，但此时还未创建user_add.jsp文件，quick fix提示了创建这一文件，于是用idea自动帮忙创建了，上述问题就解决了。然后回到原项目里发现idea没有提示quick fix，但文件路径和test项目下一模一样，按理说不应该出现问题的。 结果当我再次打开test项目，发现原本由quick fix创建的jsp文件又无法解析了，报了同样的错误。太难了！

能认证成功并存入redis中了，但是打断点发现，并没有走授权的filter，这是为什么呢？ 我试了不用gateway网关而是nginx，发现能解惑授权的filter，但无法获得header里的token，也就是先进行了授权，认证还没有开始，所有没有token 这样要怎么解决呀？

输入的第一行包含两个整数M和N (0 <= N,M <= 50)，它们代表输出内容的高度和宽度。 输出有2M行，2N列，数字之间用空格分隔。 右上角的图案是输入的水平翻转。 左下角的图案是输入的垂直翻转。 右下角的图案水平和垂直地翻转。 例如， 输入 2 2 1 2 3 4 输出 1 2 2 1 3 4 4 3 3 4 4 3 1 2 2 1 又例如 输入 2 3 1 2 3 45 678 9999 输出 1 2 3 3 2 1 45 678 9999 9999 678 45 45 678 9999 9999 678 45 1 2 3 3 2 1

我用的echart模板想生成两个相似的图表，一个在左一个在右，但是有一个显示不出来，随便将哪一个注释掉，另外一个都能正常显示，不过显示的数据一闪一闪的，像是程序将两个数据全部传到一个显示表中，这是怎么回事？ <%-- Created by IntelliJ IDEA.
