内容图文
我在我的本地数据库上运行了一个迁移,它运行良好.我正在使用另一个.yml文件用于同一模式的另一个数据库,但失败并显示错误
! com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'myTable' already exists
我怎样才能做到这一点？
liquibase包装器是否适用于mysql架构？我能够使用此文档http://www.dropwizard.io/0.7.1/docs/manual/migrations.html转储迁移
这是migrations.xml文件

如何使用dropwizard liquibase命令行生成更改日志
然后,如何运行迁移以仅迁移先前架构中的更改,以便我看不到“表已存在”错误？
每次我对Entity对象进行更改时,changelog创建都是手动进程吗？或者,当我使用doc中的’db migrate’命令时,dropwizard包装器是否识别所做的更改并更新它们？
解决方法:
添加如下的前置条件
<preConditions onFail="MARK_RAN">
<not>
<tableExists tableName="Your_Table_Name"/>
</not>
</preConditions>
例如
<changeSet author="(generated)" id="1501263805585-5">
<preConditions onFail="MARK_RAN">
<not>
<tableExists tableName="ServiceDeploy"/>
</not>
</preConditions>
<createTable catalogName="deployer" schemaName="deployer" tableName="ServiceDeploy">
<column autoIncrement="true" name="id" type="BIGINT">
<constraints primaryKey="true"/>
</column>
<column name="artifactId" type="VARCHAR(255)"/>
<column name="deploymentArtifacts" type="VARCHAR(255)"/>
<column name="executionLevel" type="INT"/>
<column name="groupId" type="VARCHAR(255)"/>
<column name="item" type="INT"/>
<column name="serviceTag" type="VARCHAR(255)"/>
<column name="url" type="VARCHAR(255)"/>
<column name="versionId" type="VARCHAR(255)"/>
<column name="deploy_id" type="BIGINT"/>
</createTable>
</changeSet>
