- 新建maven模組springmvc-002
在springmvc-002模組中的pom.xml中新增打包方式為war

- 在springmvc-002模組上右擊,新增框架支援,如圖所示:
- 補充:從Java EE 8開始，Servlet API的維護權轉交給了Eclipse Foundation的Jakarta EE社群。因此，在最新的Jakarta EE版本中，Servlet API的包名已經從javax.servlet更改為了jakarta.servlet。這意味著jakarta.servlet-api是Servlet API在Jakarta EE 9（以及後續版本）中的新命名形式。
- 新增完web框架後會自動生成web目錄,如圖所示
- 編輯web.xml檔案

- 在com.powernode.springmvc.controller新增IndexController類
package com.powernode.springmvc.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class IndexController {
@RequestMapping("/")
public String index(){
return "index";
}
@RequestMapping("/first")
public String first(){
System.out.println("業務邏輯");
return "first";
}
}
- 在WEB-INF目錄下新增templates目錄,並在此目錄下新增firstm.html檔案和index.html
