Spring 3.x 企业开发实战Chapter2 Part1

需要什么包就导入什么包，没道全也没什么，等控制台报错缺什么包就导入就是了（先把Trace复制到notepad++里面方便查看）。

学习笔记：

（1）<context:component-scan>使用说明：在xml配置了这个标签后，spring可以自动去扫描base-pack下面或者子包下面的Java文件，如果扫描到有@Component
@Controller@Service等这些注解的类，则把这些类注册为bean，这也是为什么不用再注册类似jdbcTemplate这样的对象了，感觉特别屌。。。。

（2）注意JdbcTemplate的应用
