5. jdbc.properties
jdbc.url=jdbc:mysql://127.0.0.1:3306/crm
jdbc.username=root
jdbc.password=root
6. 配置页面处理器 // 页面访问到时 *.html，通过此可以转化为 *.jsp
项目中，所有的jsp文件，都存放在WEB-INF下，该目录是一个受保护的目录，其中的资源，不允许通过浏览器的地址栏直接访问，需要在Controller层添加一个RequestMapping进行映射，然后在方法中通过转发的形式来访问页面，但是由于项目中的页面很多，我们不想为每一个页面都提供一个单独的RequestMapping，我们需要对页面访问提供统一处理！思路：凡是页面的访问，后缀名统一使用.html来完成，我们可以添加一个RequestMapping("/**/.html")来匹配所有的页面访问，然后在方法中通过访问的地址，来确定选择哪个视图。
@Controller
public class PagerController {
@RequestMapping("/**/*.html")
public String pager(HttpServletRequest request){
// 获取请求的URI
String url=request.getRequestURI();
// 会走视图解析器
// 前缀 + url.substring(0,url.lastIndexOf("."))+后缀
return url.substring(0,url.lastIndexOf("."));
}
}
不停的思考，就会不停的进步
