### 1. 创建项目 ###

**      1. 1 创建Maven项目，打包方式选择war类型**

**     1.2 解决pom.xml文件报错。因为项目打包为war，创建后webapp下缺少WEB-INF/web.xml，手动配置**

### 2. 配置文件 ###

**   2.1 pom.xml文件导入基本依赖坐标、Maven插件、定义jdk环境**

**     2.2 数据库配置文件db.properties(文件名可以自定义，后面需要将此配置文件加载到Spring配置文件)**

#数据库配置信息
    jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://182.61.40.184:3306/mine?useUnicode=true&characterEncoding=UTF-8&useSSL=false
    jdbc.username=root
    jdbc.password=ghcjgwq3qB%
    
    #初始连接数
    initSize=50
    #最大连接数
    maxSize=50

** 2.3 日志配置** **log4j.properties****(文件名可以自定义，后面需要将此配置文件加载到Spring配置文件)**

#日志级别:info  包含自定义的stdout,logfile配置
    log4j.rootLogger=info,stdout,logfile
    #stdout 输出到控制台
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender	
    #定义日志布局模式    可以灵活地指定布局模式
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    #定义输出格式
    log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %F %p %m%n
    
    
    
    #logfile 输出到指定文件 
    log4j.appender.logfile.File=D:/G(other)/temp/log/ssm.log
    #定义日志布局模式    可以灵活地指定布局模式
    log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
    # 定义输出格式
    log4j.appender.logfile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %F %p %m%n
    #每天产生一个日志文件

### 3. 根据配置文件创建相关包 ###

**根据配置文件中的配置，创建相关的实体类层、Controller层、Service层和dao层以及对应的mapper映射文件。**
