我正在尝试使用文档中指定的72.1.1 Automatic property expansion using Maven使用不同的maven配置文件,但我无法使其与特定配置文件一起使用。
我有以下 pom.xml
:
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>test</groupId>
<artifactId>test</artifactId>
<version>0.0.1-SNAPSHOT</version>
<profiles>
<profile>
<id>local</id>
<activation>
<property>
<name>profileName</name>
<value>local</value>
</property>
</activation>
<properties>
<wildcard.for.customproperty>valueA</wildcard.for.customproperty>
</properties>
</profile>
<profile>
<id>external</id>
<activation>
<property>
<name>profileName</name>
<value>external</value>
</property>
</activation>
<properties>
<wildcard.for.customproperty>valueB</wildcard.for.customproperty>
</properties>

</resources>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
这非常简单 application.properties
:
custom.property=@wildcard.for.customproperty@
我使用Spring Tool Suite运行maven构建,具有以下目标:
clean install -DprofileName=local
构建SUCCESS,但目标文件夹中的application.properties
仍然包含未解析的@...@
占位符。
如果我在两个配置文件之一的pom.xml中添加这个简单的行:
<activeByDefault>true</activeByDefault>
占位符已正确解析。
此配置有什么问题?

您已将spring-boot-starter-parent
声明为项目的依赖项,而不是将其用作项目的父项。它应该像这样声明:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.9.RELEASE</version>
</parent>
然后,您还应该从其他Spring Boot依赖项中删除<version>
声明。资源配置也是多余的,所以我建议删除它。总而言之,这将使您的pom看起来类似于以下内容:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

我已经解决了以下配置:
的pom.xml:
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>test</groupId>
<artifactId>test</artifactId>
<version>0.0.1-SNAPSHOT</version>
<profiles>
<profile>
<id>local</id>
<activation>
<property>
<name>profileName</name>
<value>local</value>
</property>
</activation>
<properties>
<wildcard.for.customproperty>valueA</wildcard.for.customproperty>
<activatedProperties>local</activatedProperties>
</properties>
<build>
<finalName>myBuild-local</finalName>
</build>
</profile>
<profile>
<id>external</id>
<activation>
<property>
<name>profileName</name>
<value>external</value>
</property>
</activation>
<properties>
<wildcard.for.customproperty>valueB</wildcard.for.customproperty>
<activatedProperties>external</activatedProperties>
</properties>
<build>
<finalName>myBuild-external</finalName>
</build>
</profile>
</profiles>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
<version>1.5.9.RELEASE</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<version>1.5.9.RELEASE</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.7</version>
<configuration>
<delimiters>
<delimiter>@{*}</delimiter>
</delimiters>
<useDefaultDelimiters>false</useDefaultDelimiters>
</configuration>
</plugin>
</plugins>
</build>
</project>
application.properties:
custom.property=@{wildcard.for.customproperty}
spring.profiles.active=@{activatedProperties}
最后,最重要的一步:
在STS中,你需要在项目中使用clic - &gt;属性 - &gt; Maven标签
您需要指定有效的个人资料。
由于某些原因,即使您将-PprofileName或配置文件直接放在Maven构建的配置文件字段中,STS也不会应用该配置文件。
