使用Maven创建web项目(SSM框架)

1.创建一个project

2.输入相关信息

3.选择maven

4.选择项目地址

5.添加pom包

6.在项目中新建java resources 等项目文件夹 和 log4j.properties文件

7.在spring文件夹中新增 applicationContext.xml

8.新建jdbc.properties

driver=com.mysql.jdbc.Driver  
url=jdbc:mysql://127.0.0.1:3306/dianping  
user=root  
password=root
#定义初始连接数
initialSize=0  
#定义最大连接数
maxActive=20  
#定义最大空闲
maxIdle=20  
#定义最小空闲
minIdle=1  
#定义最长等待时间
maxWait=60000  

9.修改log4j.xml

#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/comment.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

10.修改web.xml
