需要做的配置如下

<profiles>
        <profile>
            <id>dev</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <build>
                <filters>
                    <filter>vars/vars.dev.properties</filter>
                </filters>
            </build>
        </profile>
        <profile>
            <id>sit</id>
            <build>
                <filters>
                    <filter>vars/vars.sit.properties</filter>
                </filters>
            </build>
        </profile>
        <profile>
            <id>pre</id>
            <build>
                <filters>
                    <filter>vars/vars.pre.properties</filter>
                </filters>
            </build>
        </profile>
        <profile>
            <id>prod</id>
            <build>
                <filters>
                    <filter>vars/vars.prod.properties</filter>
                </filters>
            </build>
        </profile>
    </profiles>

其中vars所在的目錄為

pom文件中一定要有如下的配置 缺一不可

<plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <configuration>
                    <useDefaultDelimiters>false
 
</useDefaultDelimiters>
                    <delimiters>
                        <delimiter>$[*]</delimiter>
                    </delimiters>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
            
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>2.3
 
.2</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <encoding>UTF-8</encoding>
                </configuration>
            </plugin>
        </plugins>
        
        <resources>
            <resource>
                <directory>${basedir}/src/main/resources</directory>
                <filtering>true</filtering>
            </resource>
        </resources>

尤其要註意 resources標簽，只有包含在resources標簽裏面的配置文件 裏面的${key}才會被替換掉，如果不配resources這種配置文件是不會生效的。
