spring boot + maven 配置多个环境【每个环境多个properties文件】

灰太狼 2023-06-07 05:52 22阅读 0赞

最近想做一个spring boot项目，因为开发和生产环境配置不一样，所以想配置两个环境。在网上查了很多资料，都讲了如何用maven配置多个环境，和如何用application.properties加载配置文件，这两种方式都只能够配置一个application.properties文件。但是我每个环境中分成了多个properties文件，且命名规则不是application-dev.properties这种格式。不过最后还是弄出来了。

##### 项目目录 #####

下面是我的总结：

#### 1、修改pom文件 ####

无关的部分已删掉

<?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">
    	<build>
    		<finalName>ihome</finalName>
    		<resources>
    			
    			<resource>
    				<directory>src/main/resources/conf/${ profile.env}</directory>
    				<filtering>true</filtering>
    			</resource>
    			
    			
    			<resource>
    				<directory>src/main/resources/static</directory>
    				<targetPath>static/</targetPath>
    				<filtering>true</filtering>
    			</resource>
    			
    			
    			<resource>
    				<directory>src/main/resources/templates</directory>
    				<targetPath>templates/</targetPath>
    				<filtering>true</filtering>
    			</resource>
    			
    			
    			<resource>
    				<directory>src/main/resources/META-INF</directory>
    				
    				<targetPath>META-INF/</targetPath>
    				<filtering>true</filtering>
    			</resource>
    		</resources>
    		<plugins>
    			<plugin>
    				<groupId>org.springframework.boot</groupId>
    				<artifactId>spring-boot-maven-plugin</artifactId>
    			</plugin>
    		</plugins>
    	</build>
    
    	
    	<profiles>
    		<profile>
    			<id>sit</id>
    			<activation>
    				<activeByDefault>true</activeByDefault>  
    			</activation>
    			<properties>
    				
    				<profile.env>sit</profile.env> 
    			</properties>
    		</profile>
    		<profile>
    			<id>product</id>
    			<properties>
    				<profile.env>product</profile.env>
    			</properties>
    		</profile>
    	</profiles>
    </project>

#### 2、通过xml加载properties ####

新建spring-context.xml

<?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
           xmlns:context="http://www.springframework.org/schema/context"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd">
    
        
        <context:property-placeholder location="classpath:*.properties" ignore-unresolvable="true"/>
    
    </beans>

#### 3、加载xml ####

在启动类中添加注解 **@ImportResource(\{“classpath:META-INF/spring/\*.xml”\})**

PS: **META-INF/\*\*/\*.xml** 表示加载 **META-INF** 目录下所有目录中的后缀值 **.xml** 的文件

经过以上三步多个环境就配好了，需要注意的是，启动项目的时候需要通过maven来启动
