springboot项目 使用java -jar 使用固定的application.yml 不适用jar包里面的配置

1、问题描述

当我们部署项目在服务器的时候，每次打jar包都要将配置换成服务器环境的配置。那样该来该去比较麻烦，现在我们采取单独配置的方式。在服务器配置好之后，每次打包都不需要关注配置的事情了。

如图使用箭头所指的配置

2、演示

 nohup java -jar one-studio-0.0.1-SNAPSHOT.jar &

 

 

3、项目源码解释

路径：private static final String DEFAULT_SEARCH_LOCATIONS = "classpath:/,classpath:/config/,file:./,file:./config/";

 

/**
 * {@link EnvironmentPostProcessor} that configures the context environment by loading
 * properties from well known file locations. By default properties will be loaded from
 * 'application.properties' and/or 'application.yml' files in the following locations:
 * 

 * 
classpath:
 * 
file:./
 * 
classpath:config/
 * 
file:./config/:
 * 
 * 

 * Alternative search locations and names can be specified using
 * {@link #setSearchLocations(String)} and {@link #setSearchNames(String)}.
 * 

 * Additional files will also be loaded based on active profiles. For example if a 'web'
 * profile is active 'application-web.properties' and 'application-web.yml' will be
 * considered.
 * 

 * The 'spring.config.name' property can be used to specify an alternative name to load
 * and the 'spring.config.location' property can be used to specify alternative search
 * locations or specific files.
