今天我在Ebean和play2.0上遇到了一个小问题。我在de.ppi.psec.services.AuthenticationServiceImpl第333行写了一些东西
Ebean.find(PsecUser.class).where().eq("byLoginname", loginname).findUnique();
并获取以下Stacktrace
[error] application - Problem during validate Login

我想知道为什么我没有在stacktrace中找到我的班级。我尝试了类似于旧的Ebean-app的东西，在那里我得到了信息。那么为什么我没有在stacktrace中找到我的课程呢？我解决了这个问题，所以我确定错误发生在de.ppi.psec.services.AuthenticationServiceImpl第333行。
