  • Maven和Spring mvc下的页面的跳转与取值

    (此处tomcat的端口设置为80)

    例如:在testForm.jsp里提交表单,在ok.jsp里取值

    testForm.jsp页面代码如下:

    <%@ page contentType="text/html;charset=UTF-8" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>页面的跳转与取值</title>
    </head>
    <body>
        <form action="../../api/ceshilei/ceshifangfa" method="post">
            门店编码<input name="num" />
            门店名称<input name="name"/>
            <input id="btnSubmit" type="submit" value="提交"/>
        </form>
        
    </body>
    </html>

    处理器类TestFormSubmit.java进行接收处理,代码如下:

     1 package com.thinkgem.jeesite.modules.store.dao.ceshi1;
     2 
     3 import javax.servlet.http.HttpServletRequest;
     4 import javax.servlet.http.HttpServletResponse;
     5 
     6 import org.springframework.stereotype.Controller;
     7 import org.springframework.ui.Model;
     8 import org.springframework.web.bind.annotation.RequestMapping;
     9 
    10 import com.thinkgem.jeesite.common.config.Global;
    11 import com.thinkgem.jeesite.modules.store.entity.ceshi1.TestEntity;
    12 import com.thinkgem.jeesite.modules.store.entity.daily.TStoresDaily;
    13 
    14 @Controller   //用于标识是处理器类
    15 @RequestMapping(value="api/ceshilei")     //请求到处理器类的绑定
    16 public class TestFormSubmit {
    17     
    18     @RequestMapping(value="ceshifangfa")
    19     public String ceshi(TestEntity te, HttpServletRequest request, HttpServletResponse response, Model model){
    20         System.out.println("test ing ");
    21         model.addAttribute("testentity",te);
    22         return "modules/store/ceshi1/ok";
    23     }
    24     
    25 //    @RequestMapping(value="ceshifangfa")          //请求到处理器功能方法的绑定
    26 //    public String ceshi(String num, String name, HttpServletRequest request, HttpServletResponse response, Model model){
    27 //        System.out.println("test ing ");
    28 ////        model.addAttribute("testentity",te);
    29 //        model.addAttribute("num",num);
    30 //        model.addAttribute("name",name);
    31 //        System.out.println("num=="+num);
    32 //        System.out.println("name=="+name);
    33 ////        return "modules/store/ceshi1/ok";
    34 //        return "redirect:ok";    //重定向,值在地址栏有显示,但是页面没有
    35 //    }
    36     
    37     @RequestMapping("toForm")
    38     public String toForm() {
    39         return "modules/store/ceshi1/testForm";
    40     }
    41     
    42     @RequestMapping("ok")
    43     public String ok() {
    44         return "modules/store/ceshi1/ok";
    45     }
    46     
    47 }

    最终接收值的页面ok.jsp,代码如下:

    <%@ page contentType="text/html;charset=UTF-8" %>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>页面的取值</title>
    </head>
    <body>
    
        提交的门店编码是${testentity.num }<br>
        提交的门店名称是${testentity.name }<br>
            
    </body>
    </html>

    在地址栏输入http://localhost/api/ceshilei/toForm,请求到处理器类value为api/ceshilei的类,并调用请求方法value值为toForm的方法。该toForm方法返回一个要访问的目标文件路径(去掉前缀和后缀的路径,前缀和后缀在spring-mvc.xml中有说明),此处就是testForm.jsp。

    在testForm.jsp页面填写表单并提交,action为"../../api/ceshilei/ceshifangfa"。即调用处理器类value为api/ceshilei的类,并调用请求方法value值为ceshifangfa的方法(此处为ceshi)。该方法接收提交的表单传来的值并把值addAttribute给model,并返回一个要访问的目标文件路径。页面跳转到ok.jsp。

    ok.jsp用el表达式取值。
