SSM(springmvc+spring+mybatis)基本框架搭建
此配置基于3.2版本搭建
此配置不详细解释底层，需要研究自行百度，末尾提供源码包
实际上我采用mybatis的原因在于，对于新手而已，我觉得他容易上手很多。
首先xml配置文件主要有3个，另外两个properties配置文件（log4j打印sql到控制台，方便进行调试，mysql.properties文件则是配置的数据库的一些链接参数）,文件全放于src下面即可
log4j.properties（打印sql到控制台，方便调试）
log4j.rootLogger=DEBUG, Console
#Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
mysql.properties
#driverClassName=com.mysql.jdbc.Driver #在配置数据库连接池的时候，有一个选项validationQuery，该选项用来验证数据库连接的有效性 validationQuery=SELECT 1 jdbc_url=jdbc:mysql://localhost:3306/boke?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull jdbc_username=root jdbc_password=123456
