Day73 SSM项目 搭建框架

编码风格变换

1、编程风格：
在Eclipse上创建Web项目，默认会产生一个WebRootWEB-INFlib目录，jar包复制到该目录后会自动加载到Web App Libraries库中
配置编码格式：
 window-preferences 搜索encoding  
                          workspace     textfile encoding  :utf-8
                          jsp files          encoding:   utf-8
                          其他默认为utf-8
UTF-8简介：
UTF-8（8-bit Unicode Transformation Format）是一种针对Unicode的可变长度字符编码，又称万国码。由Ken Thompson于1992年创建。现在已经标准化为RFC 3629。UTF-8用1到6个字节编码Unicode字符。用在网页上可以统一页面显示中文简体繁体及其它语言（如英文，日文，韩文）。
2、配置文件：
  applicationContext-dao.xml
  applicationContext-service.xml
  applicationContext-tx.xml
  jdbc.properties
 springmvc.xml
 log4J.properties
  mybatis.xml                      配置log4J   配置实体类别名
  web.xml
      在写配置文件时，ctrl+shift+t 搜索需要的类名的全限定路径。
3、包形式
 com.bjsxt.项目名.mapper
 com.bjsxt.项目名.service
 com.bjsxt.项目名.service.impl
 .......................等
4、SVN的使用。
使用方式一：直接使用eclipseSVN插件
使用方式二：使用客户端+eclipseSVN插件   客户端更新，然后在eclipse下创建项目进行开发。


疑问：  不使用依赖注入 
          没有设置编码过滤器的init.


其他知识：
网站： http://apache.org/
maven ：http://mvnrepository.com/
所有的配置文件在spring都有默认设置，如果自定义，就走默认设置

        乐观锁
        悲观锁
