我成功地将Maven配置文件链接到Spring配置文件。在下文中,我将解释我是如何做到的:

在里面 pom.xml

<!-- PROFILES -->
<profiles>
    <profile>
        <id>dev</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <properties>
            <spring.profiles.to.active>dev</spring.profiles.to.active>
        </properties>
    </profile>
    <profile>
        <id>uat</id>
        <properties>
            <spring.profiles.to.active>uat</spring.profiles.to.active>
        </properties>
    </profile>
    <profile>
        <id>prod</id>
        <properties>
            <spring.profiles.to.active>prod</spring.profiles.to.active>
        </properties>
    </profile>
</profiles> 

2-激活Maven过滤:

这将允许我们解析所提到的文件夹中的占位符${…}(在本例中是${spring.profiles.to.activate})。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <webResources>
            <resources>
                <directory>${basedir}/src/main/webapp/WEB-INF</directory>
                <filtering>true</filtering>
                <targetPath>WEB-INF</targetPath>
            </resources>
        </webResources>
    </configuration>
</plugin>

3-激活轮廓弹簧

在里面 appengine-web.xml

<appengine-web-app
    xmlns="http://appengine.google.com/ns/1.0">
    <version>1</version>
    <threadsafe>true</threadsafe>
    <runtime>java8</runtime>
    <system-properties>
        <property name="spring.profiles.active" value="${spring.profiles.to.active}" />
    </system-properties>
</appengine-web-app> 

4-部署到Appengine

# Dev
mvn appengine:deploy -Pdev
# UAT
mvn appengine:deploy -Puat
#PROD
mvn appengine:deploy -Pprod

#dev profile, try adding space between -P and dev
mvn appengine:deploy  -P dev   
#uat profile, try adding space between -P and uat
mvn appengine:deploy  -P qa
#prod profile, try adding space between -P and prod
mvn appengine:deploy  -P prd
