springboot官方推薦使用application.yml配置文件,yml文件的好處,天然的樹狀結構,一目瞭然。使用的時候需要注意一些細節的地方:
原有的key,例如spring.jpa.properties.hibernate.dialect,按“.”分割,都變成樹狀的配置,key後面的冒號,後面一定要跟一個空格。
下面對比兩個文件
application.properties:
- server.port=8080
- server.session-timeout=30
- server.context-path=
- server.tomcat.max-threads=0
- server.tomcat.uri-encoding=UTF-8
-
- spring.datasource.url = jdbc:mysql://localhost:3306/spring
- spring.datasource.username = root
- spring.datasource.password = root
- spring.datasource.driverClassName = com.mysql.jdbc.Driver
- # Specify the DBMS
- spring.jpa.database = MYSQL
- # Show or not log for each sql query
- spring.jpa.show-sql = true
- # Hibernate ddl auto (create, create-drop, update)
- spring.jpa.hibernate.ddl-auto = update
- # Naming strategy
- spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
-
- # stripped before adding them to the entity manager)
- spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
application.yml:
- server:
- port: 8080
- session-timeout: 30
- tomcat.max-threads: 0
- tomcat.uri-encoding: UTF-8
-
- spring:
- datasource:
- url : jdbc:mysql://localhost:3306/springboot
- username : root
- password : root
- driverClassName : com.mysql.jdbc.Driver
- jpa:
- database : MYSQL
- show-sql : true
- hibernate:
- ddl-auto : update
- naming-strategy : org.hibernate.cfg.ImprovedNamingStrategy
- properties:
- hibernate:
- dialect : org.hibernate.dialect.MySQL5Dialect
The end!
