利用maven的resources、filter和profile实现不同环境使用不同配置文件

pom.xml:

<project>
  <build>
    <fileName>app</fileName>
    <resources>
      <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
      </resource>
      <resource>
        <directory>src/main/filters/META-INF/${env.name}/common</directory>
        <filtering>true</filtering>
        <targetPath>META-INF/common</targetPath>
      </resource>
    </resources>
  </build>
  <profiles>
    <profile>
      <id>dev</id>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>
      <properties>
        <maven.val>abc</maven.val>
        <env.name>dev</env.name>
      </properties>
    </profile>
    <profile>
      <id>sit</id>
      <properties>
        <maven.val>def</maven.val>
        <evn.name>sit</env.name>
      </properties>
    </profile>
  </profiles>
</project>

directory:

src/main/java
src/main/resources
src/main/filters/META-INF/dev/common/distribute-session.xml
src/main/filters/META-INF/sit/common/distribute-session.xml

maven command:

mvn clean install -DskipTests -Pdev
mvn clean install -DskipTests -Psit

===============================

不同的版本需要的配置文件不同：

<project> ......
<build>
        <finalName>tmcweb</finalName>
        <!--<resources>--> 注意这块不用了，使用profile自己的；
            <!--<resource>-->
                <!--<directory>src/main/resources</directory>-->
                <!--<filtering>true</filtering>-->
            <!--</resource>-->
        <!--</resources>-->
        <plugins>
            <plugin> 这里是一个插曲
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>

                <dependencies>
                    <dependency>
                        <groupId>org.mybatis.generator</groupId>
                        <artifactId>mybatis-generator-core</artifactId>
                        <version>1.3.2</version>
                    </dependency>
                </dependencies>
            </plugin>

        </plugins>
        
    </build>
    <profiles>
        <profile>
            <id>dev</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <env>dev</env>
            </properties>
            <build>
                <resources>
                    <resource> 在profile里面引入resource才可以exclude
                        <directory>src/main/resources</directory>
                        <filtering>true</filtering>
                        <excludes>
                            <exclude>META-INF/common/x-prod.xml</exclude>
                        </excludes>
                    </resource>
                </resources>
            </build>
        </profile>
        <profile>
            <id>prod</id>
            <properties>
                <env>prod</env>
            </properties>
            <build>
                <resources>
                    <resource>
                        <directory>src/main/resources</directory>
                        <filtering>true</filtering>
                        <excludes>
                            <exclude>META-INF/common/x-dev.xml</exclude>
                        </excludes>
                    </resource>
                </resources>
            </build>
        </profile>
    </profiles>
</project>

可以在profile中指定build模块，进行某些war包时html文件的排除

<profile>
  <id>prod</id>
  <properties>
    <env>prod</env>
  </properties>
  <build>
    <plugins>
      <plugin>
        <artifactId>maven-war-plugin</artifactId>
        <version>3.2.0</version>
        <configuration>
          <packagingExcludes>index.html</packagingExcludes>
        </configuration>
      </plugin>
    <plugins>
    <resources>
      <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
        <excludes>
          <exclude>dev.properties</exclude>
        </excludes>
      </resource>
    </resources>
  </build>
</profile>
