Springboot打包jar运行找不到数据库，请求不到数据？

Question

Springboot在IDEA运行没有问题，但是打包jar后在本地终端java -jar就无法访问数据库请求数据了
这是我的applocation.yml

spring:
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://****:3306/ren?useUnicode=true&characterEncoding=UTF-8&serverTimezone=Asia/Shanghai&zeroDateTimeBehavior=CONVERT_TO_NULL
    username: *
    password: *
  web:
    resources:
      static-locations: classpath:/templates/, classpath:/static/

我的application.properyies
spring.application.name=demo

然后本地报错：提示MyBatis映射器未找到和Spring Data JPA仓库未找到
