1.專案模組圖
2.完成SpringMVC的基本搭建
pom.xml（下載jar包的檔案）

//標明掃描器經過的類
@Controller
public class MainController {
//測試框架是否成功
@RequestMapping("test")
public String test(){
System.out.println("springmvc成功搭建");
return "index";
}
}
將專案釋出到伺服器上，然後訪問http://localhost:8080/test.action看控制輸出
則搭建SpringMVC成功
SprinMVC轉發、重定向、收集date資料、自定義轉換器、檔案上傳、json資料轉換
轉發

重新發布專案，瀏覽器訪問http://localhost:8080/testForword.action
重定向

在springmvc.xml添加註解驅動的配置和自定義轉換器的配置
