java - 如何使用 Liquibase 创建数据库

Question

• 我正在尝试使用 Liquibase 创建不存在的数据库。

• 我已经下载了 MySQL 并且没有对其进行任何更改

• 我的 maven 插件代码如下所示

  <plugins>
      <plugin>
          <groupId>org.liquibase</groupId>
          <artifactId>liquibase-maven-plugin</artifactId>
          <version>3.1.1</version>
          <configuration>
              <changeLogFile>src/main/resources/changelog.xml</changeLogFile>
              <driver>com.mysql.jdbc.Driver</driver>
              <url>jdbc:mysql://localhost:3306/myApp?createDatabaseIfNotExist=true</url>
          </configuration>
          <executions>
              <execution>
                  <phase>process-resources</phase>
                  <goals>
                      <goal>update</goal>
                  </goals>
              </execution>
          </executions>
      </plugin>
  </plugins>
  

当我运行 mvn clean install 时，我看到的错误是

Failed to execute goal org.liquibase:liquibase-maven-plugin:3.1.1:update (default) on project database_seed: Error setting up or running Liquibase: liquibase.exception.DatabaseException: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user ''@'localhost' to database 'myApp' -> [Help 1]

我该如何解决？

Answer 1

看起来您没有将用户名或密码作为配置的一部分传递:

( from the liquibase maven documentation )

<configuration>
  <changeLogFile>src/main/resources/changelog.xml</changeLogFile>
  <driver>com.mysql.jdbc.Driver</driver>
  <url>jdbc:mysql://localhost:3306/myApp?createDatabaseIfNotExist=true</url>
  <username>liquibaseTest</username>
  <password>pass</password>
</configuration>
