Spring Boot - Where to put properties files when deploying to Tomcat?
提问by mrik974
I've been using Spring Bootfor a few weeks already, and I'm used to work with the application.propertiesfile. I'm able to use it for simple deployment and use with java jaror mvn spring-boot:run.
我已经使用Spring Boot了几个星期了，我已经习惯了使用该application.properties文件。我可以将它用于简单的部署并与java jar或 一起使用mvn spring-boot:run。
Now I'm trying to deploy my application to a Tomcat 8.0.15application server. I've been reading of documentation, but I can't deploy the warfile because Tomcat can't find this famous application.propertiesfile. My point is, if I want to put this file out of the war, where in my Tomcat installation should I put it for it to be automatically read?
现在我正在尝试将我的应用程序部署到Tomcat 8.0.15应用程序服务器。我一直在阅读文档，但我无法部署该war文件，因为 Tomcat 找不到这个著名的application.properties文件。我的观点是，如果我想把这个文件从war.

If you don't want to change it later, just put it in the root of your classpath, e.g. if it's Maven project then inside
如果以后不想更改，只需将其放在类路径的根目录中，例如，如果它是 Maven 项目，则放在里面
<project-folder>/src/main/java/
If you want to change it later without rebuilding WAR then in Tomcat properties file
如果您想稍后在不重建 WAR 的情况下更改它，则在 Tomcat 属性文件中
catalina.properties
there is
有
shared.loader=
that makes properties files listed after equals sign accessible to deployed applications. Better use absolute paths.
这使得已部署的应用程序可以访问在等号之后列出的属性文件。最好使用绝对路径。
BTW, I would opt to use annotation-based configuration nowadays, but then again, it doesn't have the comfort of changing without rebuilding WAR.
顺便说一句，我现在会选择使用基于注释的配置，但话说回来，如果不重新构建 WAR，它就无法轻松进行更改。

Spring loads the properties from
Spring 从
1) A /config subdir of the current directory.
2) The current directory
3) A classpath /config package
4) The classpath root
See the docs(23.2 Application property files): http://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-external-config-application-property-files
请参阅文档（23.2 应用程序属性文件）：http: //docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle/#boot-features-external-config-application-property-files
This should work the same way for war(The classpath root one looks the best for me) .
这对于War应该以相同的方式工作（类路径根目录对我来说看起来最好）。

You can provide the location of properties file as part of "JAVA_OPTS" in catalina.sh/catalina.batch or setEnv.bat/setEnv.sh. set JAVA_OPTS=-Dspring.config.location=file:/D:/Appconfig/application.properties
您可以在 catalina.sh/catalina.batch 或 setEnv.bat/setEnv.sh 中将属性文件的位置作为“JAVA_OPTS”的一部分提供。设置 JAVA_OPTS=-Dspring.config.location=file:/D:/Appconfig/application.properties
Just for info:application.yaml will not be loaded by spring boot if outside war and defined like above.
仅用于 info:application.yaml 将不会被 spring boot 加载，如果在War之外并且定义如上。
