二、场景

1、项目使用的是application.properties，而不是application.yml

2、项目在本机启动是正常的

3、在Linux上启动则报错

三、排查

1、起初以为是tomcat的webapps目录下的程序不是war包，重新打包放上去，依旧报错

2、检查是否因为application配置文件的中文注释存在编码问题导致报错
2.1、调整IDEA的文件编码为UTF-8重新编译，依旧报错
2.2、删除application.properties所有中文，依旧报错

3、检查application配置文件中定义属性的格式是否正确，经过排查，属性格式并没有问题

4、通过远程调试查看源码，发现出错的并不是本地的application.properties，而是引入的自定义Jar包中的配置文件application.yml的属性定义格式有问题

调试过程

在这里插入图片描述
在这里插入图片描述
以下配置格式有误，缺少空格
在这里插入图片描述

配置属性缺少一个”空格”，并且该属性名称正好与”报错信息-45行”对应上

四、原因

引入的自定义Jar包中的配置文件application.yml的属性定义格式有问题

五、解决

调整Jar包application.yml的属性定义格式，重新发布Jar包，并更新Jar包
