Question

我正在尝试让我的春季Kotlin项目中的Ebean工作，但是在运行应用程序时，我不断收到此异常：

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。

我也尝试使用mvn ebean:init命令添加ebean.mf来控制增强，但是运行它时出现异常：

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

除了这个例外，我找不到其他人...

有人知道我该如何解决吗？

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，但是它仍然无法正常工作。在构建消息中，我可以看到我的实体得到了增强，但是仍然有例外：

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

Answer 1

文档参考：https://ebean.io/docs/getting-started/maven

请注意，您需要 -增强磁贴（您拥有的） -src / main / resources / ebean.mf（看起来像您丢失的地方吗？）

请注意，mvn ebean:init已过时，已被cli工具取代。请参阅https://ebean.io/docs/getting-started/cli-tool

还请注意，有一个有关此问题的疑难解答页面：请参阅https://ebean.io/docs/trouble-shooting

Answer 2

检查两件事以下是pom中的内容

<plugin>
            <groupId>io.ebean</groupId>
            <artifactId>ebean-maven-plugin</artifactId>
            <version>11.11.2</version>
            <executions>
                <execution>
                    <id>main</id>
                    <phase>process-classes</phase>
                    <configuration>
                        <transformArgs>debug=1</transformArgs>
                    </configuration>
                    <goals>
                        <goal>enhance</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

并且您的bean具有所有必需的注释，例如 @ Entity，@ Table和POJO扩展了io.ebean.Model
