如何将dev.log4j.properties文件复制到log4j.properties文件中进行生产战争？

Answer 1

• 使用Maven配置文件(http://maven.apache.org/guides/introduction/introduction-to-profiles.html)

• 创建"dev"和"prod"配置文件,为每个配置文件选择一组备用资源.默认情况下启用Dev.

  <profiles>
      <profile>
          <id>dev</id>
          <activation>
              <activeByDefault>true</activeByDefault>
          </activation>
          <build>
              <resources>
                  <resource>
                      <directory>src/main/resources/dev</directory>
                  </resource>
              </resources>
          </build>
      </profile>
      <profile>
          <id>prod</id>
          <build>
              <resources>
                  <resource>
                      <directory>src/main/resources/prod</directory>
                  </resource>
              </resources>
          </build>
      </profile>
  </profiles>
  

• 使用所需的配置文件通过: mvn install -Pdev 或 mvn install -Pprod

我使用maven-resources插件解决了这个问题,我在其中创建了prod目录,该目录具有生产环境的资源,并在process-resources阶段将它们复制到WEB-INF/classes目录.

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-resources-plugin</artifactId>
    <version>2.3</version>
    <executions>
        <execution>
            <id>copy-prod-resources</id>
            <phase>process-resources</phase>
            <goals>
                <goal>copy-resources</goal>
            </goals>
            <configuration>
                <outputDirectory>webapp/WEB-INF/classes</outputDirectory>
                <resources>
                    <resource>
                        <directory>src/main/resources/prod</directory>
                        <filtering>true</filtering>
                    </resource>
                </resources>
            </configuration>
        </execution>
    </executions>
</plugin>

上面的代码对我不起作用 - 必须将其更改为以下代码:

<plugin>
  <artifactId>maven-resources-plugin</artifactId>
  <executions>
    <execution>
      <id>copy-prod-resources</id>
      <phase>process-resources</phase>
      <goals>
         <goal>copy-resources</goal>
      </goals>
      <configuration>
        <!-- this is important -->
        <overwrite>true</overwrite>
        <!-- this as well (target/ was missing) -->
        <outputDirectory>${basedir}/target/classes</outputDirectory>
        <resources>
          <resource>
            <directory>src/main/resources/prod</directory>
          </resource>
        </resources>
      </configuration>
    </execution>
  </executions>
</plugin>
