在playframework的子模块中添加jpa / hibernate @Entity到实体管理器进行扫描 [英] Adding jpa/hibernate @Entity in submodule in playframework to entity manager to scan

问题描述

我在使用playframework中的子模块时遇到了hibernate实体的问题。

I have problem with hibernate entity while working with submodules in playframework.

通常（在没有子模块的单个应用程序中）我使用了该代码：

Normally (in single app without submodules) I've used that code:

package models;
    @Entity
    public class AppMode {
        public static AppMode getCurrentConfigurationEntry() {
            return JPA.em().find(AppMode.class, 1L);
        }
    }

但现在我必须告诉hibernate实体经理扫描子模块模型，因为我收到错误：

But now I have to tell hibernate entity manager to scan submodules models, cause I'm getting an error:

[IllegalArgumentException: Unknown entity: AppMode]

我在子模块中的模型类在包中：

My model class in submodule is in package:

package models.common;

我已经尝试过：

        return JPA.em().find(models.common.AppMode.class, 1L);
        return JPA.em().find(common.models.AppMode.class, 1L);

但我收到同样的错误：

[IllegalArgumentException: Unknown entity: models.common.AppMode]

我的问题是：如何在play子项目中配置hibernate以在运行时将子模块类添加到类路径？

My question is: How to configure hibernate in play subproject to add submodules models class to classpath at runtime?

我在两个build.sbt文件中都声明了libraryDependencies with hibernate。

I have in both build.sbt files declared libraryDependencies with hibernate.

我是否应该为每个模块设置persistence.xml文件/配置？

Should I have persistence.xml file/configuration for each module?

推荐答案

我必须手动添加映射思想xml persistance文件并使用注释映射：@Entity

I have to mannually add mapping thought xml persistance file and also using Annotation Mapping: @Entity
