Play Framework：无法在 Ebean 服务器中注册 class
Play Framework: cannot register class in Ebean server
我正在尝试从 java 6 升级到 7。在 Java 6 中一切正常。
但是当我使用Java 7时，播放出现以下错误
Cannot register class [models.ActivityMetrics] in Ebean server
In conf/dev.conf at line 43.
41
42 evolutionplugin=disabled
43 ebean.default = "models.*" <<<<<<<<<<<<<<<<<<<<<
44
是maven项目。它构建成功，但在 运行 时出现上述错误。
我正在使用 play 2.2.0。
我曾尝试使用 clean, compile, play 推荐的命令序列来回答过去的类似问题，但没有帮助。
使用 Java 7 而不是 Java 6 时，对模型的要求是否会发生变化？关于我应该改变什么的任何建议。
更新：
在日志文件中找到以下堆栈跟踪。

使用 getter 而不是直接访问字段后错误消失了
以下更改有效。
