In the Java Web development process, processing form data is an important part of the common is the form post processing a single piece of data, but also encountered one time to submit multiple data to the server, as follows:

JSP page is generally used in the loop Insert input box, and all the ID and name is the same prefix, convenient server access

1 <  items= "${objlist}"  var= "obj">2     < id = "key_${obj."   Id} "  name=" key_${obj. Id} "/>3</c:foreach>

Server-side Get parameter code:

1@RequestMapping (value = "/xxxsave", method =requestmethod.post)2  PublicString Paypropssave (FinalHttpServletRequest Request) {3 4     FinalEnumeration<string> enums =Request.getparameternames (); //Get request all parameters 5 6     FinalList<obj> objlist =NewArraylist<obj>();7 8      while(Enums.hasmoreelements ()) {9         FinalString paramname =enums.nextelement (). toString ();Ten         if(Paramname.startswith ("Key_") {//filter all parameters starting with Key_ One             FinalString Elementvalue =Request.getparameter (paramname); A             Finalobj obj =NewObj (); - Obj.setid (elementvalue); -             . the             . -             . - Objlist.add (props); -         } +     } -  + objservice.saveobjlist (objlist); A     ... at     ... -     ... -  - return"XXX"; -  -}
