1、Access denied for user ''@'localhost' to database 'bug'
    mysql -u root

　　mysql> use mysql;

　　mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';

　　mysql> FLUSH PRIVILEGES;

2、Error nested exception is java.lang.UnsupportedClassVersionError: Bad version number in .class file (unable to load class com.integration.entity.User)
BuildPath/Jre lib/Java -c 三者一致即可

3、Error Cannot find class [com.integration.action.LoginAction] for bean with name 'loginAction' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]; nested exception is java.lang.ClassNotFoundException: com.integration.action.LoginAction
com.integration.action.LoginAction 有拼写错误

4、创建mysql 表的例子

CREATE DATABASE if not exists Bug DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
use Bug;
drop table if exists `USER`;
create table if not exists `USER`（
id int(10) NOT NULL auto_increment,
name varchar(100) default null,
password varchar(100) default null,
type varchar(100) default null，
primary key（id）
);
