Jakarta ee 测试DeltaSpike存储库无法注入EntityManager
我正在尝试为DeltaSpike存储库运行一个简单的测试。但是,我无法注入实体管理器。我使用的是位于以下位置的生产商和测试来源:Jakarta ee 测试DeltaSpike存储库无法注入EntityManager,jakarta-ee,cdi,jboss-weld,deltaspike,Jakarta Ee,Cdi,Jboss Weld,Deltaspike,我正在尝试为DeltaSpike存储库运行一个简单的测试。但是,我无法注入实体管理器。我使用的是位于以下位置的生产商和测试来源: @ApplicationScoped public class EntityManagerProducer { @Produces public EntityManager getEntityManager() { return Persistence .createEntityManagerFactory("pr

}
在测试资源下的META-INF文件夹中,我有一个persistence.xml文件,其中定义了主测试持久性单元:
<persistence version="2.0"

在JavaSE中使用CDI需要将beans.xml
放入META-INF
尽管这是可选的,因为JavaEE7
然后,将发现模式设置为带注释的,应该会检测到您的生产者
以下是一个工作配置:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.source>1.8</maven.compiler.source>
<deltaspike.version>1.8.2</deltaspike.version>
<weld.version>3.0.4.Final</weld.version>
</properties>
我将使用Lombok和SLF4J:
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.16.20</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.25</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.25</version>
<scope>test</scope>
</dependency>
以下是我的CDI生产者,DeltaSpike数据需要它们,并将UUID作为私钥注入:
package fr.fxjavadevblog;
import javax.enterprise.context.ApplicationScoped;
import javax.enterprise.inject.Produces;
import javax.persistence.EntityManager;
import javax.persistence.Persistence;
import java.util.UUID;
/**
* composite of CDI Producers.
*
* @author robin
*/
@ApplicationScoped
public class Producers
{
public static final String UNIT_NAME = "cdi-deltaspike-demo";
/**
* produces the instance of entity manager for the application and for DeltaSpike.
*/
@Produces
@SuppressWarnings("unused") // just remove the warning, because the field serves as CDI Producer and the IDE cannot detect it.
private static EntityManager em = Persistence.createEntityManagerFactory(UNIT_NAME).createEntityManager();
/**
* produces randomly generated UUID for primary keys.
*
* @return UUID as a HEXA-STRING
*
*/
@Produces
@InjectedUUID
@SuppressWarnings("unused") // just remove the warning, because the method serves as CDI Producer and the IDE cannot detect it.
public String produceUUIDAsString()
{
return UUID.randomUUID().toString();
}
}
此类使用名为@injecteduid
的自定义CDI限定符:
package fr.fxjavadevblog;
import javax.inject.Qualifier;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;
import static java.lang.annotation.ElementType.*;
import static java.lang.annotation.RetentionPolicy.RUNTIME;
/**
* CDI Qualifier for UUID Producers
*
* @author robin
*/
@Qualifier
@Retention(RUNTIME)
@Target({METHOD, FIELD, PARAMETER, TYPE})
public @interface InjectedUUID
{
}
以下是我的JPA实体,使用Lombok和CDI注释:
package fr.fxjavadevblog;
import lombok.*;
import javax.enterprise.context.Dependent;
import javax.inject.Inject;
import javax.persistence.*;
import java.io.Serializable;
/**
* simple JPA Entity, using Lombok and CDI Injected fields (UUID).
*
* @author robin
*/
// lombok annotations
@NoArgsConstructor(access = AccessLevel.PROTECTED) // to avoid direct instanciation bypassing the factory.
@ToString(of = {"id","name"})
@EqualsAndHashCode(of="id")
// CDI Annotation
@Dependent
// JPA Annotation
@Entity
public class VideoGame implements Serializable {
@Id
@Inject @InjectedUUID // ask CDI to inject an brand new UUID
@Getter
private String id;
@Getter @Setter
private String name;
// this field will work as a flag to know if the entity has already been persisted
@Version
@Getter
private Long version;
}
下面是我的实体类的一个简单工厂:
/**
* simple Factory for creation VideoGame instances populated with UUID, ready to persist.
* This factory is need to get a proper Entity. Entities must not be created with the "new" operator, but must be build
* by invoking CDI.
*
* @author robin
*/
public class VideoGameFactory
{
/**
* creates and brand new VideoGame instance with its own UUID as PK.
*
* @return instance of a VideoGame
*/
public static VideoGame newInstance()
{
// ask CDI for the instance, injecting required dependencies.
return CDI.current().select(VideoGame.class).get();
}
}
最后但并非最不重要的是,我的实体的DeltaSpike数据响应:
package fr.fxjavadevblog;
import org.apache.deltaspike.data.api.EntityRepository;
import org.apache.deltaspike.data.api.Repository;
/**
* CRUD (and much more) interface, using DeltaSpike Data module.
*
* @author robin
*/
@Repository
interface VideoGameRepository extends EntityRepository <VideoGame, String>
{
// nothing to code here : automatic Repo generated by DeltaSpike
}
Lombok和UUID生成器的使用是可选的
您可以在github上找到完整的代码源代码,并克隆repo:我在Deltaspike和数据库存储库的Junit5集成测试中遇到了类似的问题。
基本上,当使用Junit5
@Test
注释时,我无法注入存储库。我不得不使用Junit4@Test
注释作为解决方法。我添加了这个beans.xml。但是,下一个问题是:java.lang.ClassNotFoundException:org.jboss.weld.events.WeldEvent。当我使用Weld版本2.1.2.Final时,异常是:ClassNotFoundException:javax.transaction.SystemException。有没有办法测试ApacheDeltaspike?试试上面所有的DEP。我将weld se core更改为weld se以获得一个包含DEP的着色jar。仍然不起作用-NoClassDefFoundError:org/apache/deltaspike/cdise/api/CdiContainerLoadertry weld se Shadded而不是weld se。我将制作一个演示项目,我将尽快在GitHub上发布。在pom.xml中是否包含对JPA和Hibernate的依赖?您能否在问题中发布完整的pom.xml。
