The difference between Springboot's application.properties and. yml

Now our Application.properties file content is:

[Plain]View Plain Copy

2. server.port=8090
4. Server.session-timeout=30
6. Server.context-path=
8. Server.tomcat.max-threads=0
10. Server.tomcat.uri-encoding=utf-8
14. Spring.datasource.url = Jdbc:mysql://localhost:3306/newbirds
16. Spring.datasource.username = root
18. Spring.datasource.password = Mymysql
20. Spring.datasource.driverClassName = Com.mysql.jdbc.Driver
22. # Specify the DBMS
24. Spring.jpa.database = MYSQL
26. # Show or not log for each SQL query
28. Spring.jpa.show-sql = True
30. # Hibernate DDL Auto (Create, Create-drop, update)
32. Spring.jpa.hibernate.ddl-auto = Update
34. # Naming strategy
36. Spring.jpa.hibernate.naming-strategy = Org.hibernate.cfg.ImprovedNamingStrategy
40. # stripped before adding them to the Entity manager)
42. Spring.jpa.properties.hibernate.dialect = Org.hibernate.dialect.MySQL5Dialect

Many of the official demos are configured with YML files.

YML file benefits, natural tree-like structure, at a glance. But it was painful to change application.properties to APPLICATION.YML.

Here is the APPLICATION.YML content after replacement:

[Plain]View Plain Copy

2. Server
4. port:8090
6. Session-timeout:30
8. tomcat.max-threads:0
10. Tomcat.uri-encoding:utf-8
14. Spring
16. DataSource
18. Url:jdbc:mysql://localhost:3306/newbirds
20. Username:root
22. Password:mymysql
24. DriverClassName:com.mysql.jdbc.Driver
26. Jpa:
28. Database:mysql
30. Show-sql:true
32. Hibernate:
34. Ddl-auto:update
36. Naming-strategy:org.hibernate.cfg.improvednamingstrategy
38. Properties
40. Hibernate:
42. Dialect:org.hibernate.dialect.MySQL5Dialect

Note the point:

1, the original key, such as Spring.jpa.properties.hibernate.dialect, press "." Split, all into a tree-like configuration

2,key after the colon, must follow a space

3, delete the original application.properties. Then be sure to execute the maven-x clean install

Springboot's application.properties differs from the. Yml
