Liquibase忽略Oracle DB的AutoIncrement=“true”

Question

 create table cat_component.organisation (
   id number(19,0) generated as identity,
    archived number(1,0),
    is_in_avaloq_group number(1,0) not null,
    mdm_uuid varchar2(255 char),
    name varchar2(255 char),
    primary key (id)
)

 <changeSet author="blabla (generated)" id="1582733383680-5">
    <createTable tableName="organisation">
        <column autoIncrement="true" name="id" type="NUMBER(19, 0)">
            <constraints primaryKey="true" primaryKeyName="organisationPK"/>
        </column>
        <column name="archived" type="NUMBER(1, 0)"/>
        <column name="is_in_avaloq_group" type="NUMBER(1, 0)">
            <constraints nullable="false"/>
        </column>
        <column name="mdm_uuid" type="VARCHAR2(255 CHAR)"/>
        <column name="name" type="VARCHAR2(255 CHAR)"/>
    </createTable>
</changeSet>

您可能已经注意到，缺少了“生成为标识”，这使我相信不管出于什么原因，AutoIncrement=“true”被忽略了。

我使用Oracle 12.1.0.2和org.LiquiBase:LiquiBase-Core 3.8.2。OJDBC驱动程序版本为19.3.0.0。分级属性为：

spring.datasource.url=jdbc:oracle:thin:@//host:1522/SID
spring.datasource.driverClassName=oracle.jdbc.OracleDriver
spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.format_sql=true
spring.datasource.username=user
spring.datasource.password=pass
spring.jpa.database-platform=org.hibernate.dialect.Oracle12cDialect
spring.jpa.show-sql=true

logging.level.org.hibernate.SQL=debug
logging.level.org.hibernate.type=trace

spring.datasource.continue-on-error=true
spring.datasource.platform=oracle

spring.liquibase.url=${spring.datasource.url}
spring.liquibase.user=${spring.datasource.username}
spring.liquibase.password=${spring.datasource.password}
spring.liquibase.url=${spring.datasource.url}
spring.liquibase.user=${spring.datasource.username}
spring.liquibase.password=${spring.datasource.password}
spring.liquibase.change-log=classpath:/db/changelog/db.changelog-master.xml
spring.liquibase.default-schema=${spring.jpa.properties.hibernate.default_schema}
spring.liquibase.liquibase-schema=${spring.jpa.properties.hibernate.default_schema}

我读过互联网，我知道我的Oracle版本与此列类型兼容，并且我不需要创建额外的Oracle序列。有什么线索会出什么问题吗？

似乎是LiquiBase中的一个bug。我刚刚在这里找到了它https://liquibase.jira.com/projects/core/issues/core-3524？filter=allissues&orderby=updated%20desc&keyword=Oracle

正如它所说的，有一个解决办法，就是添加

 generationType="BY DEFAULT"

在每个列定义处，其中使用了autoincrement=“true”。
