一、序言

在SpringBoot工程里面可以通过application-*.yml的方式实现多环境打包。但是打包的时候会把所有的.yml配置文件都打到包里。
本篇简介下,通过maven来控制哪些配置需要打包。

二、修改配置文件

1、修改pro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 https://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>2.5.3</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.hong</groupId>
    <artifactId>springboot-test</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>springboot-test</name>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
      .....
    </dependencies>


    <profiles>
        <profile>
            <id>dev</id>
            <properties>
                <!--使用${environment}获取值-->
                <environment>dev</environment>
            </properties>
        </profile>
        <profile>
            <id>test</id>
            <properties>
                <environment>test</environment>
            </properties>
        </profile>
        <profile>
            <id>prod</id>
            <properties>
                <environment>prod</environment>
            </properties>
        </profile>
    </profiles>

    <build>
        <finalName>springboot-test-${environment}</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <excludes>
                        <exclude>
                            <groupId>org.projectlombok</groupId>
                            <artifactId>lombok</artifactId>
                        </exclude>
                    </excludes>
                </configuration>
            </plugin>
        </plugins>
        <resources>
            <!--排除环境配置文件-->
            <resource>
                <directory>src/main/resources</directory>
                <excludes>
                    <exclude>application-*.yml</exclude>
                    <exclude>application.yml</exclude>
                </excludes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <filtering>true</filtering>
                <!-- 打包时包含的文件 -->
                <includes>
                    <!--suppress UnresolvedMavenProperty -->
                    <include>application-${environment}.yml</include>
                    <include>application.yml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>
</project>

2、修改application.yml文件

spring:
  profiles:
    active: @environment@

三、配置完成后如何启动

四、maven根据环境变量来打包
