Mysql Liquibase主键在H2上创建两次

一开始的问题只是H2数据库。在其他数据库（MySQL）上，它工作正常，没有问题

由（jHipster）生成的配置：

简介：戴夫

配置文件：测试（内存中）

现在Liquibase changelog：

<changeSet author="newbie" id="1449941926339-1">
    <createTable tableName="ENUM_DESCENT">
        <column name="descent_of_disease" type="VARCHAR(255)">
            <constraints nullable="false"/>
        </column>
    </createTable>
</changeSet>

<changeSet author="newbie" id="1449941926339-2">
    <loadData encoding="UTF-8"
              file="config/liquibase/descent_of_disease.csv"
              separator=";"
              tableName="ENUM_DESCENT"/>
</changeSet>

<changeSet author="newbie" id="1449941926339-3">
    <createTable tableName="DISEASE_DESCENTS">
        <column name="disease_id" type="BIGINT">
            <constraints nullable="false"/>
        </column>
        <column name="descent_descent_of_disease" type="VARCHAR(255)">
            <constraints nullable="false"/>
        </column>
    </createTable>
</changeSet>

<changeSet author="newbie" id="1449941926339-4">
    <addPrimaryKey columnNames="disease_id, descent_descent_of_disease"
                   constraintName="PRIMARY"
                   tableName="DISEASE_DESCENTS"/>
</changeSet>

<changeSet author="newbie" id="1449941926339-5">
    <addPrimaryKey columnNames="descent_of_disease"
                   constraintName="PRIMARY"
                   tableName="ENUM_DESCENT"/>
</changeSet>

解决方法：

<changeSet author="newbie" id="1449941926339-4">
    <addPrimaryKey columnNames="disease_id, descent_descent_of_disease"
                   constraintName="PRIMARY_DISEASE_DESCENTS"
                   tableName="DISEASE_DESCENTS"/>
</changeSet>

<changeSet author="newbie" id="1449941926339-5">
    <addPrimaryKey columnNames="descent_of_disease"
                   constraintName="PRIMARY_ENUM_DESCENT"
                   tableName="ENUM_DESCENT"/>
</changeSet>

如果在创建表之后添加主键，liquibase将使用
更改表。。。添加约束…
。并且不能有多个同名约束。所以H2报告了一个错误

您已经找到了解决方法

另一种方法可能是将主键定义添加到create table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
createtable…
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…
语句中使用
PRIMARY KEY
。因此，使用mySQL DB liquibase将把您的
addPrimaryKey
更改集转换为类似
ALTER TABLE…ADD PRIMARY KEY…
）谢谢！或更简单的
请不要在标题中添加标签。无需在标题中添加“[已解决]”。您已将下面的答案标记为已接受。这标志着这个问题已经解决了。几秒钟前，我得到了应该解决的建议。
