Am getting values in Ajax page
function GetInfoDivision()
{
var data = $("#storeName").val();
$.ajax({
type : "POST",
contentType : "application/json",
url : "hello",
data : JSON.stringify(data),
dataType : 'json',
//timeout : 100000,
success : function(map) {
console.log("SUCCESS: ", data);
display(data);
},
error : function(e) {
console.log("ERROR: ", e);
display(e);
},
done : function(e) {
console.log("DONE");
}
});
But Controller page getting null value ...Ajax data value not passed to the controller
@RequestMapping(value="/hello", method = RequestMethod.POST)
public String employeeLogin(ModelMap model, HttpServletRequest request) {
String sname = request.getParameter("storeName");
System.out.println("s="+sname);
shopModel s = new shopModel();
s.setStoreName(sname);
//boolean result = employeeService.employeeLogin(employee);
boolean result =false;
if(result == true){
model.addAttribute("message", "Successfully logged in.");
}
else
{
model.addAttribute("message", "Username or password is wrong.");
}
return "redirect:index.jsp";
}
You should use the @RequestBody
annotation in the parameter of the controller function.
@Autowired
private HttpServletRequest request;
@RequestMapping(value="/hello", method = RequestMethod.POST)
public String employeeLogin(@RequestBody ModelMap model) {
If storeName is just a string then you can use @RequestParam
@RequestMapping(value="/hello", method = RequestMethod.POST)
public String employeeLogin(ModelMap model, HttpServletRequest request,
@RequestParam(value = "storeName", required = false) String storeName) {
String sname = storeName;
}
and in Ajax call you can have call like
url : "hello" + "?storeName=" + data
and remove below property in Ajax call
data : JSON.stringify(data),
Your Ajax will look like below:
function GetInfoDivision()
{
var data = $("#storeName").val();
$.ajax({
type : "POST",
contentType : "application/json",
url : "hello" + "?storeName=" + data,
dataType : 'json',
//timeout : 100000,
success : function(map) {
console.log("SUCCESS: ", data);
display(data);
},
error : function(e) {
console.log("ERROR: ", e);
display(e);
},
done : function(e) {
console.log("DONE");
}
});
@RequestMapping(value = "hello", method = RequestMethod.POST)
@ResponseBody
public String methodname(@RequestParam("data") String data) {
...
return "";
}
