spring mvc + mybatis 整合框架

（由于图片全部没有显示，下载链接：http://pan.baidu.com/s/1kUIE01h）

首先放几个该放的包（注意：后面两个mybatis-spring-1.1.1.jar mybatis-3.1.1.jar是因为不导入这两个包sql就不会在控制台打印，感觉调试的时候有点不方便，不需要的话就没什么）

下面还有几个包是用来使用json的，就可以直接返回字符串在网页上，如果不导入直接访问方法的话，会返回一个字符串名的jsp

文件目录如下：

接下来就是几个配置文件

applicationContext-dao.xml

db.properties 数据库的
jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/music

jdbc.username=root

jdbc.password=root

log4j.properties 打印日志的，建议看下log4j日志怎么配置，根据需要来

### set log levels ###

log4j.rootLogger = INFO , stdout

### export Console ###

log4j.appender.stdout = org.apache.log4j.ConsoleAppender

log4j.appender.stdout.Target = System.err

log4j.appender.stdout.layout=org.apache.log4j.SimpleLayout

log4j.logger.com.ibatis=DEBUG

log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG

log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG

log4j.logger.java.sql.Connection=DEBUG

测试是否配置成功：写好controller之后看能否用@controller这种注解，在这里面写一个方法用来测试

run server之后，看打印log日志是否正确，我记得应该出现这种才行

下面试我写的测试controller截图：

运行截图：

这个就算完了，需要用什么功能再导入包，虽然知道maven很方便，但我之前试的时候老是出问题，决定还是采用导入包的形式，勿嫌弃我out了
