当尝试使用 Morphia for MongoDB 启动 Play Java 应用程序时，我得到以下堆栈跟踪，这是由于重新编译已编译的过滤器类型引起的：

Internal Server Error (500) for request GET /

Compilation error (In {module:morphia-1.2.3d}/app/morphia/Filter.java around line 8)
The file {module:morphia-1.2.3d}/app/morphia/Filter.java could not be compiled. Error raised is : The type Filter is already defined

当从 application.conf 和 dependencies.yml 加载 morphia 模块时会发生此问题

要解决它，请转到您的 application.conf 并注释掉“加载 morphia 模块”下面的行，然后重新启动 Play。

# load morphia module 
#module.morphia=${play.path}/modules/morphia-1.2.3d
