SSM博客登录注册

我的博客采用的是 spring+springmvc+mybatis框架，用maven和git管理项目，之后的其他功能还有待进一步的学习。

首先新建一个maven项目，我的项目组成大概就这样，

建立好项目后，配置pom.xml文件，pom文件是maven用来导入项目相关jar包的关键文件，

pom.xml

配置好pom.xml文件后，配置spring相关文件，spring-mvc.xml，spring-mybatis.xml

配置完这些文件后 ，把log4j的也配置一下
------
log4j

#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n配好所有配置文件以后，根据在数据库中建好的表，创建实体类，dao，mapper.xml以及对应service和serviceImpl，之后创建controller
写好对应的业务逻辑，这样，一个简单的SSM框架的登录注册功能就完成辣。项目地址：https://github.com/alexbibihere/web-ssm我写好了登录注册以后，前台页面还剩很多东西要写，还有很多东西要学习，等准备充分了，再开始接着完成这个博客吧。
