Spring boot项目maven的profile多环境配置不自动替换变量的问题解决

Spring boot项目maven的profile多环境配置不自动替换变量的问题解决

 

在网上找了很久,配置都很简单,但是个人程序就是不能自动替换变量,最终单独测试,发现原来是引用spring boot parent的问题

引用一位博主的话"spring-boot为了保护application.yml和application.properties，修改了默认的占位符${...}为@...@，而后发现resources插件有一个配置项"

<useDefaultDelimiters>true</useDefaultDelimiters>

解决办法:

 在build里面加plugin

 <pluginManagement>
			<plugins>
				<plugin>
					<artifactId>maven-resources-plugin</artifactId>
					<configuration>
						<encoding>utf-8</encoding>
						<useDefaultDelimiters>true</useDefaultDelimiters>
					</configuration>
				</plugin>
			</plugins>
		</pluginManagement>

下面分享完整的配置,一共有两块,一块是profiles配置,一块是build

其中prifiles里面定义的 properties属性会替换.properties文件里面的变量 

例如 application.properties里面有一个mapdb.path=${mapdb.path}

会被替换成正确的

<build>
		<resources>
			<resource>
				<directory>src/main/resources</directory>
				<excludes>
					<exclude>dev/*</exclude>
					<exclude>prod/*</exclude>
				</excludes>
			</resource>
			<resource>
				<directory>src/main/resources/${profiles.active}</directory>
				<filtering>true</filtering>
				<includes>
					<include>**/*.properties</include>
					<include>**/*.xml</include>
				</includes>
			</resource>
			<resource>
				<directory>src/main/resources/</directory>
				<filtering>false</filtering>
				<includes>
					<include>**/*.xml</include>
				</includes>
			</resource>
		</resources>
		<pluginManagement>
			<plugins>
				<plugin>
					<artifactId>maven-resources-plugin</artifactId>
					<configuration>
						<encoding>utf-8</encoding>
						<useDefaultDelimiters>true</useDefaultDelimiters>
					</configuration>
				</plugin>
			</plugins>
		</pluginManagement>
	</build>

 下面是profiles定义

<profiles>
		<profile>
			<id>dev</id>
			<properties>
				<mapdb.path>${basedir}/mapdb</mapdb.path>
				<profiles.active>dev</profiles.active>
			</properties>
			<activation>
				<activeByDefault>true</activeByDefault>
			</activation>
		</profile>

		<profile>
			<id>production</id>
			<properties>
				<profiles.active>prod</profiles.active>
			</properties>
		</profile>
	</profiles>
