Question

我正在尝试在spring应用程序中创建我的第一个liquibase更改日志。我用maven执行liquibase，但它不起作用。

我用maven执行liquibase。 mvn liquibase：update。

执行后，我得到错误，我需要在模式位置的标题中包含偶数uris：

我的问题是堆栈跟踪说我在7号位置52的架构位置需要偶数个uris。但是我的标题行不在第7行但在第4行。我在intelliJ终端中执行了liquibase并且在cmd。

Answer 1

在maven日志中，你有：

SchemaLocation: schemaLocation-Wert = 'http://www.liquibase.org/xml/ns/dbchangelog 
http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.0.xsd
http://www.liquibase.org/xml/ns/dbchangelog-ext 
http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd 
http://www.liquibase.org/xml/ns/dbchangelog-ext' muss eine gerade Anzahl an URIs haben.

所以尝试使用：

<databaseChangeLog
        xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext"
        xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.0.xsd
        http://www.liquibase.org/xml/ns/dbchangelog-ext http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd">

您使用的是什么版本的liquibase？

此外，您的changeSet应该有preconditions，因此当您使用现有数据库执行它们时，它们不会失败。

因此：

<changeSet id="1" author="tobias">
    <preConditions onFail="MARK_RAN">
        <not>
            <tableExists tableName="Entwickler"/>
        </not>
    </preConditions>
    <createTable tableName="Entwickler">
        <column name="id" type="int" autoIncrement="true">
            <constraints primaryKey="true" nullable="false"/>
        </column>
        <column name="name" type="varchar(50)"/>
        <column name="webseite" type="varchar(50)"/>
        <column name="gruendungsdatum" type="BIGINT"/>
    </createTable>
</changeSet>

此外，表名应以小写字母开头。

尝试制作你的changeSets原子。一个changeSet - 一个数据库更改。不要将所有表的创建放在一个changeSet中。

liquibase changelog - uris必须是均匀的
