application.yml配置–这样配置启动服务器之后会报上面的异常

###################  spring配置  ###################
spring:
  devtools:
    restart:
      enabled: true #是否开启开发者工具（true/false）
      additional-paths: src/main/java
      exclude: static/**,WEB-INF/view/**

解决方法

修改application.yml文件

spring:
  devtools:
    restart:
      enabled: true #是否开启开发者工具（true/false）
     #additional-paths: src/main/java
      exclude: static/**,WEB-INF/view/**

• 注释这个配置即可#additional-paths: src/main/java
