SpringBoot多环境配置文件切换

news 2025/5/25 8:58:29

resources下application.yml、application-dev.yml、application-prod.yml多个配置文件。

spring:profiles:active: dev

spring:profiles:active: prod

一般都是通过修改spring.profiles.active值来修改加载不同环境的配置信息，可以把切换的dev/prod放到pom.xml文件来实现，避免手动修改。

1. 示例代码结构

在这里插入图片描述

2. pom文件

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.0</version></parent><groupId>vip.buddha</groupId><artifactId>springboot-demo</artifactId><version>1.0-SNAPSHOT</version><properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies><profiles><!-- 开发环境 --><profile><id>dev</id><activation><activeByDefault>true</activeByDefault></activation><properties><package.environment>dev</package.environment></properties></profile><!-- 生产环境 --><profile><id>prod</id><activation><activeByDefault>false</activeByDefault></activation><properties><package.environment>prod</package.environment></properties></profile></profiles><build><resources><resource><directory>src/main/resources</directory><filtering>true</filtering><!-- 添加以下配置，明确包含YAML文件 --><includes><include>**/*.yml</include></includes></resource></resources><plugins><plugin><artifactId>maven-resources-plugin</artifactId><configuration><delimiters><delimiter>${}</delimiter> <!-- 使用 ${} 作为占位符 --></delimiters><useDefaultDelimiters>false</useDefaultDelimiters> <!-- 禁用默认的 @..@ --></configuration></plugin></plugins></build></project>

3. application文件

spring:profiles:active: ${package.environment}

4. application-dev文件

spring:datasource:url: jdbc:mysql://localhost:3306/dev_dbusername: dev_userpassword: dev_password

5. application-prod文件

spring:datasource:url: jdbc:mysql://localhost:3306/prod_dbusername: prod_userpassword: prod_password

6. TestController文件

package vip.buddha.controller;import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
public class TestController {@Value("${spring.datasource.url}")private String url;@Value("${spring.datasource.username}")private String username;@Value("${spring.datasource.password}")private String password;@RequestMapping("/test")public void test() {System.out.println("url:" + url);System.out.println("username:" + username);System.out.println("password:" + password);}
}

7. Main文件

package vip.buddha;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class Main {public static void main(String[] args) {SpringApplication.run(Main.class, args);}
}
