application.properties 文件和 application.yml 文件有什么区别呢?
yml文件的好处,天然的树状结构,一目了然,实质上跟properties是差不多的。
官方给的很多demo,都是用yml文件配置的。
注意点:
1,原有的key,例如spring.jpa.properties.hibernate.dialect,按“.”分割,都变成树状的配置
2,key后面的冒号,后面一定要跟一个空格
3,把原有的application.properties删掉。然后一定要执行一下 maven -X clean install
示例:
#application.yml server: port: 8086 spring: datasource: name: test url: jdbc:mysql://192.168.1.112:3306/test username: root password: xxx # 使用druid数据源 type: com.alibaba.druid.pool.DruidDataSource driver-class-name: com.mysql.jdbc.Driver filters: stat maxActive: 20 initialSize: 1 maxWait: 60000 minIdle: 1 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: select 'x' testWhileIdle: true testOnBorrow: false testOnReturn: false poolPreparedStatements: true maxOpenPreparedStatements: 20
