[Java知识库]docker-compose打包springboot+mysql

springboot配置

mysql的连接方式使用mysql的镜像名而不是ip

server:
  port: 8888
#连接池
spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: root
    url: jdbc:mysql://mysql:3306/test
  thymeleaf:
    cache: false #关闭thymeleaf缓存

#整合mybatis
mybatis:
  type-aliases-package:  com.lxs.entity #别名搜索
  mapper-locations: classpath:/mybatis/*.xml
