  • Failed to load property source from 'file:/*****/target/classes/application.yml' (classpath:/application.yml)

      使用springboot默认创建项目,是application.properties,改成yml格式时,需要注意以下几点:

    • 注释中不能用中文
    • yml格式,采用tree形状,key和value中的“冒号",冒号与值之间要有空格,如 username: root
    • 同一级别节点格式要对齐,下面红包部分由于没有对齐,运行项目时报错
    spring:
      datasource:
        url: jdbc:mysql://127.0.0.1:3306/business?useUnicode=true&characterEncoding=utf-8&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
        username: root
         password: root
        driverClassName: com.mysql.cj.jdbc.Driver
        # use mysql
      jpa:
        database: mysql
          # is show  sql
        show-sql: true

    pagehelper:
        helperDialect: mysql
        reasonable: true  # To minimize or maximize the number of pages when the input page is negative or larger
        supportMethodsArguments: true
        params: count:countSql

      yml中格式错误,肉眼不太容易找出错误,推荐一个在线查看的工具:http://old.qqe2.com/jsontool/yaml.php

      修改正确后的效果
