Interface error:

Handler dispatch failed; nested exception is java.lang.AbstractMethodError:
com.shiku.im.dao.impl.FriendsDaoImpl.queryFriendsByName(ILjava/lang/String;)Ljava/util/List

Local debugging is good. An error will be reported when it is released to the test environment!

The final reason is the problem of distributed project compilation. The interface of module A is implemented in module B, and B is not compiled before compiling A.
