错误:尝试执行回滚时,未将数据库URL既未指定为参数也未指定为属性文件 [英] Error: The database URL has not been specified either as a parameter or in a properties file when trying to perform a rollback
问题描述
我正在尝试执行回滚,但是出现以下错误
I am trying to perform a rollback but I am getting the following error
The database URL has not been specified either as a parameter or in a properties file.´
我的pom文件中确实有数据库URL,如下所示,所以我认为这不是问题
I do have the database URL in my pom file as you can see below ,so I don't think that's the problem

数据库有一个密码.我也必须写吗?我该如何解决?
The database has a password . Do I have to write it too? How can I fix this?
推荐答案
我不确定通过pom.xml文件配置Liquibase的方式.我认为您可以这样尝试:
I'm not sure about the way of configuring Liquibase through pom.xml file. I think you could try this way:
-
不是在pom.xml的标记内提供所有数据库属性,而是创建"liquibase.properties".并在此文件中填充与liquibase(DB)有关的各种属性.对于创建"liquibase.properties"的帮助,文件,请访问此链接
尝试在现有pom.xml文件中使用与以下类似的配置:
Try using configuration similar to below in your existing pom.xml file:
<modelVersion>4.0.0</modelVersion>
<groupId>com.my-group.app</groupId>
<artifactId>Liqui<SampleDb>-app</artifactId>
<version>1.0-SNAPSHOT</version>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-maven-plugin</artifactId>
<version>3.9.0</version>
<configuration>
<propertyFile>liquibase.properties</propertyFile>
</configuration>
<dependencies>
<dependency>
<groupId><db_type></groupId>
<artifactId><db_type></artifactId>
</dependency>
</dependencies>
</plugin>
</plugins>
</pluginManagement>
</build>
- 您还可以通过更正现有的pom文件来尝试以下方法.此链接表示要在
<配置>
部分.可以尝试围绕< configuration>
部分中的POM文件中的liquibase属性,如下所示: - You could also try the following way by correcting your existing pom file. This link says to include liquibase attributes inside
<configuration>
section. May be try surrounding the liquibase attributes in your POM file in<configuration>
section as below:
<configuration>
<changeLogFile>changelog.xml</changeLogFile>
<url>MyJDBCConnection</url>
<username>dbuser</username>
<password>dbpassword</password>
</configuration>
是的,需要配置DB密码
干杯!
