Question

在使用Liquibase填充表时，如何为主键自动增量列生成id？使用我当前的配置，Liquibase将NULL放入ID列。

我的更改日志文件：

<?xml version="1.0" encoding="utf-8"?>
<databaseChangeLog
    xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.2.xsd">

    <property name="now" value="now()" dbms="mysql,h2"/>
    <property name="now" value="current_timestamp" dbms="postgresql"/>

    <!--
        Added the entity Skill.
    -->
    <changeSet id="20141029084149" author="jhipster">
        <createTable tableName="T_SKILL">
            <column name="id" type="bigint">
                <constraints primaryKey="true" nullable="false"/>
            </column>
            <column name="value" type="varchar(255)"/>
            <column name="description" type="varchar(255)"/>
        </createTable>

        <loadData encoding="UTF-8"
            file="config/liquibase/skills.csv"
            separator="|"
            tableName="T_SKILL"/>
    </changeSet>
</databaseChangeLog>

和skills.csv文件：

value|description
java|Java
java-ee|Java Enterprise Edition
junit|JUnit

你需要包含autoIncrement =＆＃34; true＆＃34;在createTable列标记

中

<changeSet id="20141029084149" author="jhipster">
    <createTable tableName="T_SKILL">
        <column name="id" type="bigint" autoIncrement="true">
            <constraints primaryKey="true" nullable="false"/>
        </column>
        <column name="value" type="varchar(255)"/>
        <column name="description" type="varchar(255)"/>
    </createTable>
</changeSet>

如何为loadData文件中的每一行生成主键值
