maven-war-plugin根据环境打包资源

J2EE项目在开发时，需要根据不同环境适配资源文件，maven提供了war-plugin这款打包插件，方便完成这个适配。

首先配置maven profile，再次不再详述，参见官方文档。demo中，prod的资源依旧放在src/main/resources中，dev、qa资源置于src目录外。可根据实际情况调整。

<profiles>
		<!-- dev配置 -->
		<profile>
			<id>dev</id>
			<activation>
        		<activeByDefault>true</activeByDefault>
    		</activation>
			<properties>
				<runtime.env>env/dev</runtime.env>
				<final.name>filename</final.name>
			</properties>
		</profile>
		<!-- qa配置 -->
		<profile>
			<id>qa</id>
			<properties>
				<runtime.env>env/qa</runtime.env>
				<final.name>filename</final.name>
			</properties>
		</profile>
		<!-- prod配置 -->
		<profile>
			<id>prod</id>
			<properties>
				<runtime.env>src/main/resources</runtime.env>
				<final.name>filename</final.name>
			</properties>
		</profile>
	</profiles>

然后引入maven-war-plugin插件

<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-war-plugin</artifactId>
				<version>3.0.0</version>
				<configuration>
					<webResources>
						<resource>
							<directory>${runtime.env}</directory>
							<targetPath>WEB-INF/classes</targetPath>
						</resource>
					</webResources>
					<warSourceExcludes>resources/js/**</warSourceExcludes>
				</configuration>
			</plugin>

warSourceExcludes 可以过滤掉不需要打包的资源文件

<plugin>

                	<excludes>
                        <exclude>**/*.min.js</exclude>
                        <exclude>**/*.min.css</exclude>

                        <exclude>resources/image/**</exclude>
                    </excludes>
                    
                    <includes>  
                		<include>**/*.js</include>  
                		<include>**/*.css</include>  
            		</includes>
                </configuration>
			</plugin>
