Quarkus依赖项应用程序使用不同的持久性单元触发与EntityManager相关的错误

Question

我在创建的主quarkus应用程序(名为dep-repos(中有以下类：

package com.myapps.dep.common;
@ApplicationScoped
public class DepRepository implements PanacheRepositoryBase<DepEntity, Integer> {
@Inject
@PersistenceUnit("dep")
EntityManager em;
@Transactional
public void save(final List<DepEntity> entities) {
entities.forEach(e -> em.persist(e));
}
}

我用这种方式：

package com.myapps.dep.common;
@ApplicationScoped
public class MyDep {
@Inject
DepRepository repository;
// ...
}

我使用该应用程序作为另一个quarkus应用程序的依赖：

<dependency>
<groupId>com.myapps<groupId>
<artifactId>dep-repos</artifactId>
<version>1.0.0/version>
</dependency>

我用这种方式：

package com.myapps.main;
import com.myapps.dep.common.MyDep;
@ApplicationScoped
public class MyServiceImpl implements MyService {
@Inject
MyDep myDep;
// ...
}

我在application.yml文件中定义了所有必需的属性，现在我有两个持久性单元，一个用于主应用程序，另一个与另一个dep-repos应用程序相关：

quarkus:
datasource:
db-kind: db2
username: test
password: test
jdbc:
url: jdbc:db2://<url>
"dep":
db-kind: db2
username: test
password: test
jdbc:
url: jdbc:db2://<url>
hibernate-orm:
dialect: org.hibernate.dialect.DB2Dialect
database:
generation: validate
packages: com.myapps.main
"dep":
datasource: dep
packages: com.myapps.dep

现在，当我构建应用程序时：

./mvnw package -Dquarkus.config.locations=file:/./application.yml -Pnative

我得到以下错误：

你知道怎么解决这个问题吗？

感谢

我不能100%确定这是如何工作的，但你能尝试以下方法吗？

@ApplicationScoped
public class DepRepository implements PanacheRepositoryBase<DepEntity, Integer> {
@Inject
@io.quarkus.hibernate.orm.PersistenceUnit("dep")
EntityManagerFactory emf;
@Inject
EntityManager em;
@Transactional
public void save(final List<DepEntity> entities) {
entities.forEach(e -> em.persist(e));
}
}
