Liquibase从JPA实体生成变更日志

本文介绍了Liquibase从JPA实体生成变更日志的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个Spring引导，带有一个父级和三个子级模块的spring data jpa项目.我的模块之一负责我的JPA实体.我需要使用liquibase从该实体生成一个xml变更日志.

I have a Spring boot, spring data jpa project with a parent and three children modules.One of my modules is responsible for my JPA entities.I need generate one xml changelog with liquibase from this entities.

在我的liquibase.properties中，我有代码:

In my liquibase.properties i have the code:

changeLogFile=src/main/resources/db/changelog/db.changelog-master.xml
url=jdbc:mysql://localhost:3306/test
username=root
password=root
driver=com.mysql.jdbc.Driver
outputChangeLogFile=src/main/resources/db/outputChangeLog/liquibase-outputChangeLog.xml
referenceUrl=hibernate:spring:br.com.company.vacation.domain?dialect=org.hibernate.dialect.MySQLDialect
diffChangeLogFile=src/main/resources/liquibase-diff-changeLog.xml

因此，如果我尝试执行以下命令: liquibase:diff ，我会收到错误消息:

So, if i try execute the command: liquibase:diff i receive the error:

在我的pom.xml中，我像下面这样配置了liquibase:

In my pom.xml i configured the liquibase just like this:

<plugin>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-maven-plugin</artifactId>
    <version>3.4.1</version>
    <configuration>
        <propertyFile>src/main/resources/liquibase.properties</propertyFile>
    </configuration>
        <dependencies>
            <dependency>
                <groupId>org.liquibase.ext</groupId>
                <artifactId>liquibase-hibernate4</artifactId>
                <version>3.5</version>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-beans</artifactId>
                <version>4.1.7.RELEASE</version>
            </dependency>
        </dependencies>
</plugin>

如果我执行 liquibase:generateChangeLog ，则liquibase将从我现有的数据库中生成日志...但是，如果我尝试执行 liquibase:diff ，则会收到错误消息:

If i execute the liquibase:generateChangeLog the liquibase generate the log from my existing database...But if i tried execute liquibase:diff i receive the error:

有人已经有这个问题了吗?

Someone already had this problem?

推荐答案

我解决了这个问题.

解决方案是我的pom.xml文件中缺少一个依赖项.

The solution is one dependency it's missing in my pom.xml file.

Pom.xml 

<!-- Liquibase -->
    <dependency>
        <groupId>org.liquibase</groupId>
        <artifactId>liquibase-core</artifactId>
        <version>3.4.1</version>
    </dependency>

    <dependency>
        <groupId>org.liquibase</groupId>
        <artifactId>liquibase-maven-plugin</artifactId>
        <version>3.4.1</version>
    </dependency>

<plugin>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-maven-plugin</artifactId>
    <version>3.4.1</version>
    <configuration>
        <propertyFile>src/main/resources/liquibase.properties</propertyFile>
    </configuration>
        <dependencies>
            <dependency>
                <groupId>org.liquibase.ext</groupId>
                <artifactId>liquibase-hibernate4</artifactId>
                <version>3.5</version>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-beans</artifactId>
                <version>4.1.7.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>org.springframework.data</groupId>
                <artifactId>spring-data-jpa</artifactId>
                <version>1.7.3.RELEASE</version>
            </dependency>
        </dependencies>
</plugin>
