问题：

@Intercepts({ @Signature(type = StatementHandler.class, method = "prepare", args = { Connection.class }) })
public class PaginationInterceptor implements Interceptor {......}

Exception in thread "main" org.apache.ibatis.exceptions.PersistenceException:

问题原因：

MyBatis 3.4.0 之后，StatementHandler的prepare方法做了修改

Statement prepare(Connection connection, Integer transactionTimeout) throws SQLException;

解决方法：

1.修改为

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

2.降低MyBatis版本号
