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
