idea环境基于maven整合ssm

1.首先创建maven项目

选择新建maven项目并勾选Create from archetype并选择webapp进行项目的构建，然后点击next

填写项目相关信息：
GroupID 是项目组织唯一的标识符，实际对应JAVA的包的结构，是main目录里java的目录结构。
ArtifactID是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。
设置好之后点击next。

选择maven，可以选择本地的maven或者使用idea自带的maven进行创建。然后点击next。

这里配置项目的名称，直接finish就行。

2.包结构的设置
自己手动创建项目包，创建好后的项目结构如下图所示。

这是我们是不能再Java目录下直接创建Java文件的，我们需要将包的属性改为source。如下图所示。点击左上角的file然后点击project Structs然后点击modules将mian下的Java文件夹标记为source，resources文件夹标记为resource。将test下的Java标记为test，resources标记为resource。

3.配置文件

3.1 首先配置pom.xml。由于用maven来管理项目，所以相关依赖我们不必再自己手动导入。而是用pom.xml配置相关jar包。下面是简易的pom.xml配置

pom.xml

3.2 在resource下新建jdbc.properties文件，配置数据库连接信息

driverClasss=com.mysql.jdbc.Driver  
jdbcUrl=jdbc:mysql://localhost:3306/db_ssm
username=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  

2.3 在resources下新建log4j配置文件

log4j.rootLogger=INFO,Console,File  

#控制台日志
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
log4j.appender.Console.layout=org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%p][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n  

#普通文件日志
log4j.appender.File=org.apache.log4j.RollingFileAppender  
log4j.appender.File.File=logs/ssm.log  
log4j.appender.File.MaxFileSize=10MB  
#输出日志，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][%t][%d{yyyy-MM-dd HH\:mm\:ss}][%C] - %m%n  

3.4 配置spring-mybatis.xml

基本的ssm算是搭建起来了，在下一遍博客中我将用这个架构来具体实现增删改查等操作。并详细介绍ssm的请求处理流程，以及各配置文件的具体作用。
