构建Spring项目以在另一个系统上运行 [英] Build Spring project for run on another system

问题描述

我在自己的本地系统上成功创建了一个Spring Boot项目.我想构建一个jar文件，以便可以将其安装在远程服务器上.因此我必须配置远程服务器的服务器地址和mySql地址，但是我无法构建它并且有很多错误，而且它们都很好，导致我的系统无法看到远程服务器地址和数据库.

I Successfully create a spring boot project on my own local system. I want to build a jar file so I can install it on remote server. so I had to configure server address and mySql address of remote server but I can not Build and it have many errors, and they all right cause my system can not see the remote server address and database.

这是我的.properties文件:

this is my .properties file:

spring.datasource.url=jdbc:mysql://localhost:8081/aths
spring.datasource.username=root
spring.datasource.password=
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.hibernate.ddl-auto=create
server.address=192.168.24.250
server.port=8080

如何处理它以便在其他配置上运行? (另一个IP，数据源和...) 我做对了吗?谢谢

how can handle it for running on another configurations? ( another IP, datasource, and ...) Am I doing it right or not? thanks

推荐答案

您可以在此处使用spring配置文件: 使用application-{profile}.properties格式为不同的配置文件创建不同的属性文件，例如用于开发的application-dev.properties和用于生产的application-prod.properties将配置文件特定的配置放入其中.然后，当您运行Spring Boot应用程序时，请使用SPRING_PROFILES_ACTIVE环境变量或spring.profiles.active系统属性来激活您想要的配置文件.

You can use spring profiles here : Create different property files for different profiles using application-{profile}.properties format, e.g. application-dev.properties for dev, and application-prod.properties for production put your profile specific configurations in them. Then when you're running the spring boot application, activate your intended profile using the SPRING_PROFILES_ACTIVE environment variable or spring.profiles.active system property.

最后，您将使用以下命令运行jar文件 java -jar -Dspring.profiles.active=prod application.jar

and at the end, you will run your jar file with command java -jar -Dspring.profiles.active=prod application.jar
