application.properties外面的jar文件怎么样 [英] application.properties outside jar file how to
问题描述
在你的应用程序类路径上(例如你的jar里面),你可以拥有一个
的应用程序.properties为name提供合理的默认属性值
。在新环境中运行时,可以在jar之外提供覆盖名称的application.properties
On your application classpath (e.g. inside your jar) you can have an application.properties that provides a sensible default property value for name. When running in a new environment, an application.properties can be provided outside of your jar that overrides the name
I将重复的application.properties与覆盖的名称放在与jar文件相同的路径上,但是在运行应用程序时:
I place a duplicated application.properties with overridden name on the same path as jar file, however when running the application with:
java -jar target/myproject-0.0.1-SNAPSHOT.jar
名称值未被覆盖,它仍然是指的是jar文件里面的application.properties里面的一个。我也尝试过:
The name value is not overridden, it still refers to the one inside application.properties inside jar file. I also tried:
java -Dspring.config.location=/target/application.properties -jar target/myproject-0.0.1-SNAPSHOT.jar
但它不起作用,请帮忙。
But it does not work, please help.
编辑
当我将当前目录更改为 target
并运行它,它的工作原理。
When I change the current directory to target
and run it, it works.
java -jar myproject-0.0.1-SNAPSHOT.jar
为什么?为什么不能在路径之外运行呢?
Why? Why cannot be outside the path and run it?
推荐答案
它不起作用,因为你试图从另一个启动jar文件夹:spring boot查找相对于当前文件夹的文件/文件夹。
It doesn't work because you are trying to launch the jar from another folder: spring boot looks for files/folder relative your current folder.
您可以:
1)复制 application.properties
在 ./
或 ./ config /
,相对于当前文件夹。
1) copy application.properties
either in ./
or ./config/
, relative to your current folder.
2)或指定 -Dspring.config.location
:
$ java -Dspring.config.location=target/application.properties -jar target/myproject-0.0.1-SNAPSHOT.jar
