三.springmvc.xml文件配置    

四.创建mybatist-config.xml

五.创建applicationContext.xml

六.创建log4j.properties

# rootLogger是所有日志的根日志,修改该日志属性将对所有日志起作用
# 下面的属性配置中,所有日志的输出级别是debug,输出源是con
log4j.rootLogger=debug,con
# 定义输出源的输出位置是控制台
log4j.appender.con=org.apache.log4j.ConsoleAppender
# 定义输出日志的布局采用的类
log4j.appender.con.layout=org.apache.log4j.PatternLayout
# 定义日志输出布局
log4j.appender.con.layout.ConversionPattern=%d{MM-dd HH:mm:ss}[%p]%c%n -%m%n

七.创建SaleMapper.xml

    
        
        
        
        
        
        
            
            
            
        
        
            
            
            
            
        
    
    
        SELECT *
        FROM
        sale
        AS a
        INNER JOIN product AS b ON a.productId = b.id
        INNER JOIN users AS c ON a.userId = c.id
    

 
        SELECT *
        FROM
        sale
        AS a
        INNER JOIN product AS b ON a.productId = b.id
        INNER JOIN users AS c ON a.userId = c.id
        ORDER BY a.saleDate ASC
    
    
        SELECT *
        FROM
        sale
        AS a
        INNER JOIN product AS b ON a.productId = b.id
        INNER JOIN users AS c ON a.userId = c.id
        ORDER BY a.totalPrice ASC
    
    
        SELECT COUNT(*) FROM Users WHERE userName=#{userName} and password=#{password}
    
    
         SELECT * FROM Product
    

八.创建实体类、Mapper程、Service层、Web层

。。。。。。。

九.部署项目
