jspページに1つの送信ボタンが2つあります。フォーム1を自分のコントローラに送信します。 2つの画像とフォームフィールドで構成されています。

Controller.java

@RequestMapping(value="/schoolDetails",method=RequestMethod.GET) 
    public ModelAndView getschoolDetails(){ 

    ModelAndView model = new ModelAndView(); 
    School schools=new School(); 
    Map referenceData = new HashMap(); 
    referenceData.put("schoolObject", schools); 
    ModelAndView mav = new ModelAndView("schoolDetails", referenceData);  
    return mav; 
} 



@RequestMapping(value="/addSchoolDetails",method=RequestMethod.POST) 
public String addSchoolDetails(@ModelAttribute("schoolObject") School school, 
     @RequestParam("image") MultipartFile image,@RequestParam("logo") MultipartFile logo){ 

    if(result.hasErrors()){ 
     return "schoolDetails"; } 

    Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal(); 
    CustomUser user=null; 
    if (principal instanceof CustomUser) { 
    user = ((CustomUser)principal); 
    } 

    return "schoolDetails"; 
}

あなたのJSPが

以下のように、名前のイメージも名前のイメージにタグを追加してJSPファイルを修正した任意のタグが含まれていないとして

<form:form method="POST" role="form" action="/GenericApp/addSchoolDetails" enctype="multipart/form-data" modelAttribute="schoolObject"> 

    <div class="col s3" id="sName">School Name :</div> 
    <input id="form_text" name="schoolname" type="text" placeholder="School Name"/> 

    <div class="col s3" id="sName">Email ID :</div> 
    <input id="form_text" name="email" type="email" placeholder="Email ID"/> 

    <div class="col s3" id="sName">State :</div> 
    <select name="state" id="state_id" > 
     <option>State</option> 
     <option>Karnataka</option>            
    </select> 
    <div class="col s12 m4 l4" id="sName">Upload School Logo :</div> 
     <input type="file" name="logo" id="fileUpload" accept="image/x-png, image/gif, image/jpeg"/>
