Java PlayFramework 2.5.12 JPAApi注入错误,java,hibernate,jpa,inject,playframework-2.5,Java,Hibernate,Jpa,Inject,Playframework 2.5,当我尝试注射时，我看到一个错误。我从中得到的集成示例。我使用的不是“hibernate entitymanager”，而是“hibernate core”。但是，使用“hibernate entitymanager”时会出现相同的错误版本 @Singleton public class UsersApi implements Mappings { @Inject JPAApi jpaApi; ... } hibernate核心-5.2.8 播放-2.5.12

当我尝试注射时，我看到一个错误。我从中得到的集成示例。我使用的不是

“hibernate entitymanager”

，而是

“hibernate core”

。但是，使用

“hibernate entitymanager”

时会出现相同的错误

版本

@Singleton
public class UsersApi implements Mappings {

    @Inject
    JPAApi jpaApi;

    ...
}

我最近有一个项目与

“org.hibernate”%”hibernate entitymanager“%”5.2.8.Final“

根据@nielstockton的评论，我在DefaultJPAApi类中没有看到任何直接使用hibernate的东西

package play.db.jpa;

import play.db.DBApi;
import play.inject.ApplicationLifecycle;

import java.util.*;
import java.util.concurrent.CompletableFuture;
import java.util.function.Function;

/**

public class DefaultJPAApi implements JPAApi {

下面是我当前的配置。我使用Oracle作为数据库

是池配置的默认名称。你可以叫它任何东西，我在我的配置中叫它

oracle

希望它能解决您的问题。
