Springboot application.yml和application.properties文件的区别

application.yml和application.properties文件这两种文件都是Springboot的配置文件,注释都可以用#号来注释,只不过因为application.yml看起来更直观,更清晰。但是要注意一点:properties文件的优先级高于yml文件,即如果两个文件中都配置了端口号,只有properties中的端口号有效,而yml文件中端口配置无效。

 

首先看application.properties文件,在properties文件中是以”.”进行分割的。

#application.properties
 
server.port=8085
 
spring.datasource.type=org.apache.tomcat.jdbc.pool.DataSource
spring.datasource.url=jdbc:mysql://aliyuncs.com:3306/home?useUnicode=true&zeroDateTimeBehavior=convertToNull&autoReconnect=true
spring.datasource.username=root
spring.datasource.password=***
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
 
#mybatis.mapper-locations=classpath*:com/wanyu/fams/mapping/*Mapper.xml
#mybatis.type-aliases-package=com.wanyu.fams.model
 
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
 
spring.druid.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.druid.datasource.driverClassName=com.mysql.jdbc.Driver
spring.druid.datasource.url=jdbc:mysql://localhost:3306/spring_boot?characterEncoding=utf-8
spring.druid.datasource.username=root
spring.druid.datasource.password=xxx

而application.properties文件,都是K-V格式,并且通过” : ”引号进行赋值;

server:
  port: 8081

spring:
    datasource:
        name: test
        url: jdbc:mysql://localhost:3306/springbootdatabase
        username: root
        password: 123456
        # 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    

也就是说

properties文件中

spring.druid.datasource.username=root
spring.druid.datasource.password=123456
spring.http.multipart.maxFileSize=100Mb
spring.http.multipart.maxRequestSize=100Mb

 

等于

 

yml文件中

spring:
    datasource:
        username: root
        password: 123456

    http:
     multipart:
      maxFileSize: 100Mb
      maxRequestSize: 100Mb

注意:yml文件中
