Saya mahu mencipta skrip untuk liquibase. Apabila saya melakukan sisipan dalam skrip saya yang seterusnya, saya mahu menjana id secara automatik melalui UUID. Saya mencuba apa yang saya dapati di sana: EDIT: Saya menggunakan jawapan:

<property name="u_id" value="uuid()" dbms="mysql"/>
<changeSet id="1" author="xyz">
    <createTable tableName="persons">
        <column name="id" type="varchar(36)" defaultValueComputed="${u_id}">
            <constraints primaryKey="true" nullable="false"/>
        </column>
        <column name="name" type="varchar(50)">
            <constraints nullable="false"/>
        </column>
        <column name="surname" type="varchar(50)">
            <constraints nullable="false"/>
        </column>
        <column name="email" type="varchar(50)">
            <constraints nullable="false" unique="true"/>
        </column>
    </createTable>
</changeSet>
</databaseChangeLog>

Skrip pertama berfungsi dengan baik, jadual dibuat, tetapi apabila saya menambah skrip kedua:

<changeSet  id="2" author="xyz">
    <insert tableName="persons">
        <column  name="name"  value="name value"/>
        <column  name="surname"  value="surname value"/>
        <column  name="email"  value="email value"/>
    </insert>
</changeSet>

Sekarang ralatnya ialah:

name 'liquibase' defined in class path resource [liquibase/LiquibaseAutoConfiguration$LiquibaseConfiguration.class]:
