java - EBean增强专家

Question

我试图让 Ebean 在我的 spring Kotlin 项目中工作，但是当我运行我的应用程序时，我一直收到这个异常:

Caused by: java.lang.IllegalStateException: Bean class com.sshmanager.server.database.entity.User is not enhanced?

我已经添加了 io.ebean.tile:enhancement 插件。

我也试过用mvn ebean:init命令添加ebean.mf来控制增强，但是运行时出现异常:

Commands:
  M - Manifest - add ebean.mf to control enhancement (recommended)
  P - Test properties - Add test-ebean.properties to configure Ebean when running tests (recommended)
  L - Logging - Add test logging entry to log SQL when running tests (recommended)
  G - Generate migrations - Add GenerateDbMigration for generating DB migration scripts (recommended)
  D - Docker - Add support for running tests against Docker containers (Postgres, ElasticSearch etc)
  F - Finders - generate finders
  T - Type safe query beans - manually generate them (rather than via APT/KAPT)
  Q - Quit
  Select an command: [M/P/L/G/D/F/T/Q] > M
Select a package that will contain the entity beans
  0 - Other
  1 - com.sshmanager.server.database.entity
select one of the options above
1
---- answer: com.sshmanager.server.database.entity

我找不到其他人有这个异常(exception)......

有谁知道我该如何解决这个问题？

我正在使用最新版本的 Ebean。

编辑
我正在使用 Intellij 并刚刚安装了 Ebean 增强插件，但它仍然不起作用。在构建消息中，我可以看到我的实体得到了增强，但我仍然有异常:

java.lang.IllegalStateException: Bean class com.sshmanager.server.database.entity.User is not enhanced?

Answer 1

文档引用:https://ebean.io/docs/getting-started/maven

注意你需要 - 增强瓷砖(你有) - src/main/resources/ebean.mf(你好像哪里不见了？)

请注意，mvn ebean:init 已被弃用并被 cli 工具取代。 引用https://ebean.io/docs/getting-started/cli-tool

另请注意，这里有一个故障排除页面:请参阅 https://ebean.io/docs/trouble-shooting
