MySQL: Creating table with two foreign keys fails with “Duplicate key name” error
最佳答案
如果在创建表后添加主键，liquibase 将使用 ALTER TABLE...ADD CONSTRAINT...。并且您不能有多个同名约束。所以H2报错。
您已经找到了解决方法。
也许另一种方法是将您的主键定义添加到创建表语句中:
<changeSet author="newbie" id="1449941926339-1">
<createTable tableName="ENUM_DESCENT">
<column name="descent_of_disease" type="VARCHAR(255)">
<constraints nullable="false"/>
<constraints primaryKey="true"/>
</column>
</createTable>
</changeSet>
然后主键定义将在 CREATE TABLE... 语句中处理。
(顺便说一句:这不会发生在 mySQL 上，因为 mySQL 能够在 ALTER TABLE... 语句上使用 PRIMARY KEY。所以对于 mySQL DB liquibase 将将您的 addPrimaryKey 变更集翻译成类似 ALTER TABLE...ADD PRIMARY KEY...)

这篇文章是继上一篇文章“Observability：从零开始创建Java微服务并监控它（一）”的续篇。在上一篇文章中，我们讲述了如何创建一个Javaweb应用，并使用Filebeat来收集应用所生成的日志。在今天的文章中，我来详述如何收集应用的指标，使用APM来监控应用并监督web服务的在线情况。源码可以在地址 https://github.com/liu-xiao-guo/java_observability 进行下载。摄入指标指标被视为可以随时更改的时间点值。当前请求的数量可以改变任何毫秒。你可能有1000个请求的峰值，然后一切都回到一个请求。这也意味着这些指标可能不准确，你还想提取最小/
