如何从不同的文件加载基于spring boot的REST应用程序属性？

Question

spring boot launcher似乎在寻找＜code＞应用程序。｛xml|properties | yml 124yaml｝文件在以下位置加载属性。是否有方法指定不同的文件名或文件以从中加载属性？

$ java -Ddebug -jar target/app-1.0.jar

编辑:

是否有方法指定另一个Bean配置文件（如applicationcontext.xml）？

Answer 1

在命令行中，您可以使用以下属性来提及其他启动配置文件：

--spring.config.name="file:/path/to/application.properties"

另一种选择是：

-Dspring.config.name="file:/path/to/application.properties"

注意字符是小写的，单词分隔符是句号..

否则，您可以使用已使用键的环境变量：

>

在 *nix 系统中：

export SPRING_CONFIG_NAME=file:/path/to/application.properties

在 Windows OS 中：

set SPRING_CONFIG_NAME=file:/path/to/application.properties

以下文档资源中有更多关于Spring Boot配置的信息。

Answer 2

您可以设置springs在启动期间搜索配置文件的文件夹。

java-jartarget/app-1.0.jar-Dspring.config.location=your/config/dir/

Answer 3

您需要使用< code > @ configuration properties 来加载属性。

@ConfigurationProperties(locations = {"yourProperties.xml"})
