造成 org.yaml.snakeyaml.error.YAMLException: java.nio.charset.MalformedInputException: Input length = 2这种原因的情况

1.文件编码有问题

2.application.yml文件格式的问题

(1)注释错误引起（application.yml采用的是#注释而不是//）

(2)缩进采用tab而不是空格引起的（不同配置之间也不能有tab出现，否则会报错）

(3)冒号后面必须有空格否则会报错

(4)树状结构，前面的空格数量可能会不对，每次应2个空格

3.可能就是你的application.yml文件是通过把其他类型的文件后缀名直接改为yml生成的

最好的解决方案

（1）把application.yml中的内容全部复制，然后删除，再新建一个application.yml文件，将复制的内容拷贝进去再运行项目
（2）修改编码为UTF-8，但是我没修改成功
