@qmdx

In 3.4.0, StatementHandler#prepare(Connection) has been changed to StatementHandler#prepare(Connection,Integer).

See https://github.com/mybatis/mybatis-3/blob/master/src/main/java/org/apache/ibatis/executor/statement/StatementHandler.java#L33-L34 .

Oh, I see . thanks
Done

That was in fact my fault because I should have left the old method. Sorry. I have already added that to the release notes.

@leefinechan
to solve problem just modify the anotation of the interceptor (by add Integer.class) like this :

@Intercepts({ @Signature(type = StatementHandler.class, method = "prepare", args = { Connection.class, Integer.class }) })

[champion97]

Statement prepare(Connection var1, Integer var2) throws SQLException;
