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

在网上找了好久,配置都很简单,可是我的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@...@，然后发现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>
