我想创建 liquibase 的脚本。当我在下一个脚本中执行插入操作时，我想通过 UUID 自动生成 id。 我尝试了在那里找到的东西： 编辑：我使用了一个答案：

<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>

第一个脚本正常，表已创建，但是当我添加第二个脚本时：

<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>

现在错误是：

org.springframework.beans.factory.BeanCreationException: Error creating bean with 
name 'liquibase' defined in class path resource [liquibase/LiquibaseAutoConfiguration$LiquibaseConfiguration.class]: 
Invocation of init method failed; nested exception is liquibase.exception.LiquibaseException: liquibase.exception.MigrationFailedException:
