This article is about how to make springbootenviroment have PropertySource. I think it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

When springboot starts, the properties are loaded by various PropertySource, and a series of PropertySource is stored in enviroment sequentially. When we get the property, we use enviroment.getProperty () to get the property value in the order that propertySource is in List.

The following figure shows the value of propertySourceList in enviroment of springboot 1.5.x

The following figure shows the value of propertySourceList in enviroment of springboot 2.1.x

As you can see, after 2.x, springboot registered more ConfigurationPropertySourcesPropertySource for enviroment. The specific code is in the prepareEnvironment method of the SpringApplication class, which springboot 2 uses

ConfigurationPropertySources.attach (environment)

ConfigurationPropertySourcesPropertySource has been added to enviroment.
