Spring Web MVC Eclipse 編譯環境
Spring 3.1 + Eclipse 3.6EE + Tomcat 6 + WTP 3.2.4

  1. 前言
  2. Eclipse
    1. 新增專案
    2. 匯入Web App Libraties
    3. 匯入Java Resources
    4. 程式碼
  3. 結果

前言

補充

Eclipse

  • Spring 3.1
  • Eclipse 3.6EE
  • Tomcat 6

下載 tomcat 專案到系統內

  • WTP 3.2.4

在 Eclipse->Help->"install new software" 安裝 WTP 3.2.4 與 WTP 3.2.4 SDK

新增專案

new project -> other -> "web" : "Dynamic Web Project" -> project name = "Web1SpringMVC" -> 完成

匯入Web App Libraties

加入所有spring*.jar 到 WebContent/WEB-INF/lib/ 內

用 指令 或用 file->import->"file system" 精靈 將 spring/dist/*.jar 匯入到此資料夾

匯入Java Resources

在 java build path -> libraries : add external jars -> 選擇 spring/dist/*.jar -> ok

程式碼

  • WebContent/WEB-INF/jsp/hello.jsp 
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>

<!doctype html>
<html>
    <head>
      <meta charset="UTF-8">
        <title>First Spring MVC</title>
    </head>
    <body>
        <h1>Hello, ${user}!!</h1>
        <p>usage: hello.do?user=xx</p>
    </body>
    
</html>

  • "Java Resource"-> src/org.waue/HelloController.java 
package org.waue;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

public class HelloController implements Controller {
    private String viewPage;

    public ModelAndView handleRequest(HttpServletRequest req, 
                                            HttpServletResponse res)

        String user = req.getParameter("user");
        return new ModelAndView(viewPage, "user", user);
    }
    
    public void setViewPage(String viewPage) {
        this.viewPage = viewPage;
    }
}

結果

​http://localhost:8080/Web1SpringMVC/hello.do?user=aa
