多数情况下，我们使用maven管理多个子工程，在最后maven打包阶段将多个子工程聚合到一个jar或war包。单个子工程会有自己独立的资源配置文件，在打包的时候我们需要将其聚合在一起（各子工程中的配置文件名称不能重复）。下面提供两种方法：
1.使用maven-resources-plugin插件，下面提供代码示例：
<build> <finalName>${projectName}</finalName> <plugins> <plugin> <artifactId>maven-resources-plugin</artifactId> <version>2.5</version> <executions> <execution> <id>copy-resources</id> <phase>process-sources</phase> <goals> <goal>copy-resources</goal> </goals> <configuration> <outputDirectory>${basedir}/target/classes/</outputDirectory> <resources> <!-- 将app.framecore中的配置文件复制到该宿主工程中 --> <resource> <directory>${basedir}/../../app.framecore/src/main/resources</directory> <includes> <include>**/*.sql</include> <include>**/*.xml</include> <include>**/*.properties</include> </includes> </resource> <!-- 将app.pms.cust.api中的配置文件复制到该宿主工程中 --> <resource> <directory>${basedir}/../app.pms.cust.api/src/main/resources</directory> <includes> <include>**/*.sql</include> <include>**/*.xml</include> <include>**/*.properties</include> </includes> </resource> </resources> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.6.1</version> <configuration> <compilerArgument>-parameters</compilerArgument> <source>1.8</source> <target>1.8</target> <!-- true:跳过测试 --> <skip>true</skip> <encoding>${maven.compiler.encoding}</encoding> </configuration> </plugin> </plugins> </build>
2.直接在build节点中配置resources节点。如下代码所示：
<build> <resources> <resource> <targetPath>${basedir}/target/classes/</targetPath> <directory>${basedir}/../../app.framecore/src/main/resources</directory> <includes> <include>**/*.sql</include> <include>**/*.xml</include> <include>**/*.properties</include> </includes> </resource> <resource> <targetPath>${basedir}/target/classes/</targetPath> <directory>${basedir}/../app.pms.cust.api/src/main/resources</directory> <includes> <include>**/*.sql</include> <include>**/*.xml</include> <include>**/*.properties</include> </includes> </resource> </resources> ... </build>
不过这里需要注意的是，一旦在build中指定了resources节点，必须自己手动添加所有待整合的资源文件。因为指定了resources，maven在打包时将严格按照用户指定的resources处理资源文件。所以这里推荐方法1.
