问题：

Liquibase没有看到实体的变化

东方涛
2023-03-14

我正在尝试用liquibase配置简单的maven项目。我在liquibase maven插件和liquibase hibernate4的版本上遇到了很多问题，这些版本不会产生大的堆栈跟踪，但最终我几乎让它工作了。但当我执行mvn liquibase:diff时，它以消息＜code＞liquibase：未发现任何更改，无需执行＜/code＞结束。

这是我的诗：

在< code > src/main/Java/pl/mlewando/ff/model 中，我有一个简单的类:

package pl.mlewando.ff.model;

import lombok.Data;

import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
@Data
class User {
    @Id
    private long id;
    private String name;
}

和persistence.xml中的src/main/资源/META-INF/：

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
             version="2.0">
    <persistence-unit name="persistenceUnit" transaction-type="RESOURCE_LOCAL">
        <provider>org.hibernate.jpa.HibernatePersistenceProvider</provider>
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect" />
        </properties>
    </persistence-unit>
</persistence>

数据库liquibase_test是空的，当我执行mvn liquibase：更新与空的db.changelog.xml它创建表数据库记录和数据库记录，但在那之后，当我运行mvn liquibase： diff它仍然看不到用户表。

我做错了什么？谢谢！

编辑:

当我尝试使用此命令从命令行差异时：

liquibase 
      --driver=com.mysql.jdbc.Driver 
      --url=jdbc:mysql://localhost:3306/liquibase_test_ref 
      --username=root 
      --password=root 
    diffChangeLog 
      --referenceUrl="hibernate:spring:pl.mlewando.ff.model?dialect=org.hibernate.dialect.MySQL5InnoDBDialect"

一切正常，我最终得到这个更新日志：

但是我真的想通过maven来做。所以，再一次：我做错了什么？

我不确定这是否相关，但前段时间我在liquibase-hibernte-plugin上发现了类似的错误。我正在使用带有hiberante 4的Spring本地会话工厂，它也没有发现更改。

调试后，我发现liquibase hibernate插件使用了导入org.springframework.orm.hibernate3.LocalSessionFactoryBean转换为HibernateSpringDatabase。java，因此它无法读取我的配置。

我更改了它并生成了一个拉请求，现在它对我来说工作正常。

如果你想尝试一下，你可以使用我修改过的liquibase-hibernate-plugin，使用下面的maven依赖项:

<dependency>
    <groupId>com.github.malaguna</groupId>
    <artifactId>liquibase-hibernate</artifactId>
    <version>liquibase-hibernate4-3.6.1</version>
</dependency>

但是首先，您必须将JitPack repo添加到maven pom.xml:

<repository>
    <id>jitpack.io</id>
    <url>https://jitpack.io</url>
</repository>

希望有帮助！
