java - Spring MVC - passed http request argument not match the same String value, why? -
i'm passing email parameter value "adrian@domain.com in way:
.../confirmation?email="adrian@domain.com" that request handled following controlerr's method assign parameter modelatrribute added confirm.jsp view:
@requestmapping(value="/confirmation") public string accessconfirmationform(@requestparam(value = "email") string email, model model) { confirmationcode confcode = new confirmationcode(); confcode.setemail(email); model.addattribute("confcode", confcode); return "confirm"; } that's code confirm.jsp:
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%> <%@ page session="false" %> <html> <head> <title>confirmation</title> </head> <body> <form:form modelattribute="confcode" action="${pagecontext.request.contextpath}/confirm" method="get"> <table> <tr> <td>confirmation code email ${confcode.email}:</td> <td><form:input path="confirmationcode" /></td> <td><font color="red"><form:errors path="confirmationcode"></form:errors></font></td> <td><form:hidden path="email" value= "${confcode.email}" /></td> </tr> <tr> <td><input type="submit" value="confirm"></td> </tr> </table> </form:form> after submitting form request reirected following controller's method:
@requestmapping(value = "/confirm", method = requestmethod.get) public string confirmuser( // @requestparam(value = "email", required=false) string email, @valid @modelattribute(value = "confcode") confirmationcode confcode, bindingresult result, model model) {...} problem email variable of confcode attribute in stage not equal manualy type string "adrian@domain.com", when printing email variable on console can see excatly same string "adrian@domain.com" without trailing spaces.
it causes email variable not applicable when i'm trying email entity in dao implementation class:
//it causes null reference emails mail = entitymanager.find(emails.class, email); //it returns proper entity emails mail = entitymanager.find(emails.class, "adrian@domain.com"); i think reason why these 2 string aren't equal encoding, maybe? encoding in db latin-1 (iso 8859-1)?
how solve problem?
why both string aren't equal each other?
.../confirmation?email="adrian@domain.com"
i think param value shouldn't have double quote
