我可以通过maven build(liquibase:update目标)运行Liquibase changelog 而不会出现任何问题.现在,我希望Liquibase使用数据库凭据和从属性文件(db.properties)加载的URL,具体取决于所选的Maven配置文件:

|-- pom.xml
`-- src
    `-- main
        `-- resources
            |-- local
            |   `-- db.properties
            |-- dev
            |   `-- db.properties
            |-- prod
            |   `-- db.properties
            `-- db-changelog-master.xml
            `-- db-changelog-1.0.xml

3个属性文件中的每一个都如下所示:

database.driver = oracle.jdbc.driver.OracleDriver
database.url = jdbc:oracle:thin:@<host_name>:<port_number>/instance
database.username = user
database.password = password123

现在,而不是在POM文件本身中定义这些属性(正如在这个问题的接受答案中所解释的,liquibase使用带有两个数据库的maven不起作用),我希望它们从外部属性文件加载.我试过不同的方法无济于事:

1.我resource在POM文件中使用了Maven的元素:

<build>
      <pluginManagement>
         <plugins>
            <plugin>
               <groupId>org.liquibase</groupId>
               <artifactId>liquibase-maven-plugin</artifactId>
               <version>3.1.0</version>
               <configuration>
                  <changeLogFile>db.changelog-master.xml</changeLogFile>
                  <verbose>true</verbose>
               </configuration>
            </plugin>
         </plugins>
      </pluginManagement>
   </build>


<profiles>
    <profile>
        <id>local</id>
        <activation>
            <activeByDefault>true</activeByDefault>
        </activation>
        <build>
            <resources>
                <resource>
                    <directory>src/main/resources/local</directory>
                </resource> …

我有以下结构从maven运行一个数据库:

<plugin>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-plugin</artifactId>
            <version>1.9.5.0</version>
            <executions>
                <execution>
                    <phase>process-resources</phase>
                    <configuration>
                        <changeLogFile>src/main/resources/db.changelog.xml</changeLogFile>
                        <driver>com.mysql.jdbc.Driver</driver>
                        <url>jdbc:mysql://localhost:3306/charm</url>  
                        <username>***</username>
                        <password>***</password>
                    </configuration>
                    <goals>
                        <goal>update</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

现在我想在名为charm2的同一服务器上运行另一个数据库.我试过这个:

<plugin>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-plugin</artifactId>
            <version>1.9.5.0</version>
            <executions>
                <execution>
                    <phase>process-resources</phase>
                    <configuration>
                        <changeLogFile>src/main/resources/db.changelog.xml</changeLogFile>
                        <driver>com.mysql.jdbc.Driver</driver>
                        <url>jdbc:mysql://localhost:3306/charm</url>  
                        <username>***</username>
                        <password>***</password>
                    </configuration>
                    <goals>
                        <goal>update</goal>
                    </goals>
                </execution>
                <execution>
                    <phase>process-resources</phase>
                    <configuration>
                        <changeLogFile>src/main/resources/db.changelog.xml</changeLogFile>
                        <driver>com.mysql.jdbc.Driver</driver>
                        <url>jdbc:mysql://localhost:3306/charm2</url>  
                        <username>***</username>
                        <password>***</password>
                    </configuration>
                    <goals>
                        <goal>update</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

它不起作用.有谁知道如何解决这个问题？
