liquibase-maven-plugin liquibase：diff - 不工作（在类路径中找不到任何META-INF / persistence.xml文件）

标签： spring hibernate maven jpa liquibase

我很难运行liquibase：diff通过liquibase-maven-plugin

我有一个使用spring-boot引导的基于Spring Data JPA的应用程序。所以，不会有任何persistence.xml

以下是pom.xml的片段：

<plugin>
<groupId>org.liquibase</groupId>
<artifactId>liquibase-maven-plugin</artifactId>
<version>3.2.2</version>
<configuration>
    <propertyFile>target/classes/liquibase.properties</propertyFile>
</configuration>
<dependencies>
    <dependency>
    <groupId>org.liquibase.ext</groupId>
    <artifactId>liquibase-hibernate4</artifactId>
    <version>${liquibase_hibernate_version}</version>
    </dependency>
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>${spring.version}</version>
    </dependency>
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>${spring.version}</version>
    </dependency>
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-beans</artifactId>
    <version>${spring.version}</version>
    </dependency>
    <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>${mysql.version}</version>
    </dependency>
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-orm</artifactId>
    <version>${spring.version}</version>
    </dependency>
    <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-core</artifactId>
    <version>${hibernate.version}</version>
    </dependency>
    <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>${hibernate-entitymanager.version}</version>
    </dependency>
</dependencies>

这是liquibase.properties：

changeLogFile: classpath:/db/changelog/changelog-master.xml
diffChangeLogFile: src/main/resources/db/changelog/changelog-sql-2_0.sql
driver: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/sample
defaultSchema: sample
username: root
password: root
referenceUrl: hibernate:spring:se.sample.core.domain?dialect=org.hibernate.dialect.MySQL5Dialect
verbose: true
dropFirst: false
logging: debug

这是我正在使用的maven命令：

mvn resources:resources liquibase:diff -Pprod

这是我得到的错误：

由于我使用Spring JPA而没有任何persistence.xml，所以我无法理解如何使它工作。

有人可以指导吗？

在maven命令中添加-X以获取完整的详细信息：

我不确定您的配置有什么问题，可能是该版本中的错误或其他问题。所以我分享了我刚开始工作的那个。你可以找到full source here，但下面应该是相关的细节。

这是我的liquibase.properties 

referenceUrl=hibernate:spring:com.xenoterracide?dialect=org.hibernate.dialect.H2Dialect
changeLogFile: classpath:changelog.db-master.xml
diffChangeLogFile: changelog.xml
driver: org.h2.Driver
url: jdbc:h2:mem:testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE
username: sa
password:
verbose: true
logging: debug

我的pom.xml中的插件配置（版本来自spring platform-b​​om）

<build>
<plugins>
  <plugin>
    <groupId>org.liquibase</groupId>
    <artifactId>liquibase-maven-plugin</artifactId>
    <version>${liquibase.version}</version>
    <configuration>
      <propertyFile>liquibase.properties</propertyFile>
    </configuration>
     <dependencies>
      <dependency> <!-- optional but may use different version of hibernate than you do if not specified -->
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>${hibernate.version}</version>
      </dependency>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${spring.version}</version>
      </dependency>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-orm</artifactId>
        <version>${spring.version}</version>
      </dependency>
      <dependency>
        <groupId>org.liquibase.ext</groupId>
        <artifactId>liquibase-hibernate4</artifactId>
        <version>3.5</version>
      </dependency>
    </dependencies>
  </plugin>
</plugins>
</build>

为什么你认为这应该有效？

如果Spring Data通过支持没有META-INF/persistence.xml的持久性单元以不合规的方式扩展JPA规范，为什么Liquibase或任何其他兼容的应用程序也应该这样做？
