免责声明：我不知道这是否符合hibernate的许可证规定。
您可以将org.hibernate.annotations包提取到最终的jar包中。您将在编译时依赖于hibernate-core，但是只有org.hibernate.annotations包将包含在您的最终jar包中。
使用maven-dependency-plugin：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.8</version>
<executions>
<execution>
<id>extract-hibernate-annotations</id>
<phase>process-resources</phase>
<goals>
<goal>unpack</goal>
</goals>
<configuration>
<artifactItems>
<artifactItem>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.3.7.Final</version>
</artifactItem>
</artifactItems>
<outputDirectory>${project.build.outputDirectory}</outputDirectory>
<includes>org/hibernate/annotations/**</includes>
</configuration>
</execution>
</executions>
</plugin>
您需要将hibernate-core添加为所提供的依赖项：
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.3.7.Final</version>
<scope>provided</scope>
</dependency>
Testing:
Main.java:
import org.hibernate.annotations.SQLDelete;
@SQLDelete(sql = "delete from whatever where id = ?")
public class Main {
public static void main(String[] args) {
SQLDelete annotation = Main.class.getAnnotation(SQLDelete.class);
System.out.println("Sql delete = " + annotation);
System.out.println("Sql = " + annotation.sql());
try {
Class.forName("org.hibernate.Session");
} catch (ClassNotFoundException e) {
System.out.println("org.hibernate.Session is not present");
}
}
}

构建:
$ mvn package
$ java -jar target/so-1.0-SNAPSHOT.jar
输出：
Sql delete = @org.hibernate.annotations.SQLDelete(callable=false, check=NONE, sql=delete from whatever where id = ?)
Sql = delete from whatever where id = ?
org.hibernate.Session is not present

org.hibernate.annotations.Type
大多数情况下，@Type注解来自已存在的hibernate-core jar包中，但实际上不一定非得是hibernate-core。Java类的坐标是class_name + package + classloader。对于特殊的包名如java.lang有一些考虑因素，但是对于org.hibernate.*而言，如果你创建了自己的jar包，其中包含相同的package和同名的注解，效果将是相同的。
换句话说，如果你严格不想从hibernate-core获取@Type注解，你可以在自己的jar包中创建自己的@Type注解。
希望这能帮到你。
