maven使用fiter修改resources下文件中的内容

1、在src/main/filters目录下新建filter1.properties，文件内容如下

maven.app.name=pro-dev

2、在resources目录下新建application.properties，文件内容如下

app.name=${maven.app.name}

3、pom.xml，文件内容如下

<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">

        <filters>

        </filters>

        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <configuration>
                    <!-- 使用默认的变量标记方法即${*} -->
                    <useDefaultDelimiters>true</useDefaultDelimiters>
                </configuration>
            </plugin>
        </plugins>

        <resources>
            <resource>
                <directory>src/main/resources</directory>
                <!-- 启用过滤 -->
                <filtering>true</filtering>
            </resource>
        </resources>
    </build>
</project>

4、打包时application.properties中的${maven.app.name}将会被替换为pro-dev
