JavaWeb学习笔记-spring-01-概述(实例)

简介

• 模块
  
  • Core Container//核心容器
  • Core 基本核心工具类
  • Beans 访问文件配置，创建管理bean，IOC/DI
  • Context Beans扩展
  • Expression Language 查询、操作对象的语言模块
• Data Access/Integration
  
  • JDBC JDBC
  • ORM 关系-对象映射
  • OXM OBJECT/XML映射
  • JMS 制造和消费消息
  • Transaction 支持编程和声明式事务
• web
  
  • web web集成特性
  • web-servlet springMVC
  • web-struts struts支持
  • web-porlet porlet&web-servlet MVC实现
• AOP//面向切面
  
  • Aspects Aspectj支持
  • Instrumentation 特定服务器使用
• Test//junit和testNG测试

容器简单实例

//定义bean
public class MyTestBean {
    private String testStr = "testStr";

    public String getTestStr() {
        return testStr;
    }

    public void setTestStr(String testStr) {
        this.testStr = testStr;
    }
}

创建库表

mysql -uroot -proot
drop database if exists sampledb;
create database sampledb default characterset utf8;
use sampledb;

create table t_user(
    user_id int auto_increment primary key,
    user_name varchar(30),
    password varchar(32),
    last_visit datetime,
    last_ip varchar(32)
)engine=innodb;

###创建用户登录日志表
create table t_login_log(
    login_log_id int auto_increment primary key,
    user_id int,
    ip varchar(23),
    login_datetime datetime
)engine=innodb;

插入初始化数据

insert into t_user (user_name,password) values('admin','123456');
commit;
