运行外部文件夹中的类路径 war 文件命令 Spring java

Question

我有一个 war 包，想包含一个外部 class 路径：

在我的控制器中：

我有以下代码：

WebApplicationclass:

@SpringBootApplication
@PropertySource( "classpath:config.properties" )
public class WebApplication{

   public static void main(String[] args){
        SpringApplication.run(WebApplication.class, args);
   }
}

控制器Class:

@Controller
@PropertySource( "classpath:config.properties" )
public class ApplicationController{

     //doing some stuff here

}

我的文件夹：

|-project

|-src
   |-main
     |-java
       |-com.mypage.temp
         |-WebApplication.java (main class)
       |-com.mypage.temp.controller
         |-ApplicationController (Controller)
     |-resources
       |- [some stuff & not putting my properties file here to include externally]
     |-deploy
       |-config.properties

但是当我构建

project.war

我放了一个远程服务器（unix）：

|project
  |-bin
    |-project.war
  |-config
    |-config.properties
Something/something/something/bin/project.war Something/something/something/config/config.properties

运行命令：

java -jar -Dclasspath=/something/something/something/config/config.properties project.war

错误：

 Failed to parse configuration class [com.mypage.temp.WebApplication];
 nested exception is java.io.FileNotFoundException: class path resource
 [config.properties] cannot be opened because it does not exist

从official documentation开始，SpringBoot依靠spring.config.locationSpringBoot属性指定环境属性文件的位置。
您可以在命令行中提供它。

You can also refer to an explicit location using the spring.config.location environment property (comma-separated list of directory locations, or file paths).

$ java -jar myproject.jar --spring.config.name=myproject or

$ java -jar myproject.jar --spring.config.location=classpath:/default.properties,classpath:/override.properties

所以，试试看：

java -jar project.war --spring.config.location=classpath:/something/something/something/config/config.properties
