spring boot配置文件

1、spring boot通常打成一个jar文件发布，想修改配置文件比较麻烦，但他提供了一种读取外部配置文件的方式。在代码的主类中增加如下代码

System.setProperty("spring.config.location","/Users/pud/Desktop/test.properties");

通过spring.config.location这个关键字指定配置文件的路径，熟悉java的同学应该知道还有其他方式来指定这个配置，如在jvm参数中通过-D来指定，这里不多说了。

这样在src/main/resources目录下有一个application.properties中就可以这样添加配置信息了，使用${}

spring.datasource.url=${url}

spring.datasource.username=${username}

spring.datasource.password=${password}

spring.datasource.driver-class-name=com.mysql.jdbc.Driver

在外部的配置文件，定义如下：

url=jdbc:mysql://localhost:3306/product
username=root
password=123456
driver=com.mysql.jdbc.Driver

2、在application.properties这个文件中可以配置哪些内容？如下：

# SPRING CONFIG (ConfigFileApplicationListener)

spring.config.name= # config file name (default to 'application')

spring.config.location= # location of config file
