1.开发环境搭建
http://blog.csdn.net/zhshulin/article/details/30779873
2.maven项目创建：
http://blog.csdn.net/zhshulin/article/details/37921705
3.配置文件详解
在照着很多大佬们之前发表的的文章中我自己搭建了，但是出了很多问题，最后终于解决了，现在我总结一下自己的小小成果。
首先看一下项目的具体结构
项目结构
3.1详解pom.xml

注意：我使用的是oracle数据库，在引入oracle配置文件时会报错
这里写图片描述

3.3 log4j.properties

#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
