Spring boot項目maven的profile多環境配置不自動替換變量的問題解決

Spring boot項目maven的profile多環境配置不自動替換變量的問題解決

 

在網上找了很久,配置都很簡單,但是個人程序就是不能自動替換變量,最終單獨測試,發現原來是引用spring boot parent的問題

引用一位博主的話"spring-boot爲了保護application.yml和application.properties，修改了默認的佔位符${...}爲@...@，而後發現resources插件有一個配置項"

<useDefaultDelimiters>true</useDefaultDelimiters>

解決辦法:

 在build裏面加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,一共有兩塊,一塊是profiles配置,一塊是build

其中prifiles裏面定義的 properties屬性會替換.properties文件裏面的變量 

例如 application.properties裏面有一個mapdb.path=${mapdb.path}

會被替換成正確的

<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定義

<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>
