ajax request not working with Spring boot

[Ng Sharma]

I'm try hit url using ajax but it not working.

Javascript File

function updateLeadSquaredCapturing(){
    var leadDetails = {
          firstName    : parseJwt(getAuthToken()).name,
          phone        : String(userMobileNumber),
          emailAddress : parseJwt(getAuthToken()).emailId,
          mx_courses   : segmentList
    }
    alert(JSON.stringify(leadDetails));
    $.ajax({
            url: apiBasePath + "/create/user/leadcapture",
            data: JSON.stringify(leadDetails),
            type: "POST",
            contentType: "application/json",
            dataType: "text",
            success: function (response) {
            alert("Success  "+ JSON.stringify(response));
              console.log('success');
            },
            error: function (response) {
              alert("Error   "+JSON.stringify(response));
                console.log('fail.');
            }
          });
}

Controller

@RestController
@RequestMapping({"/api/v1"})
public class LeadController {

    @PostMapping("/create/user/leadcapture")
    @ResponseBody public String createLeadCapture(@Valid @RequestBody LeadCapture capture) {

      System.out.println("Name : " +  capture.getFirstName());
      System.out.println("Email : " + capture.getEmailAddress());
      System.out.println("ToString : " + capture);

      return "Successful";
    }
}

LeadCapture Class

public class LeadCapture {

  private String firstName;
  private String mobileno;
  private String emailAddress;
  private String mx_courses;

  /**Getter And Setter*/
}

I merged your stuff with the following thread. I hope that is okay by you.

Every time I try to send a post request, I get 500 error.Post request via postman works fine too, so there is no problems on the server side. What is the Mistake?

Controller

package com.neostencil.services;

import com.neostencil.leadsquard.LeadCapture;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.http.*;
import org.springframework.stereotype.Service;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;
import org.springframework.web.util.UriComponentsBuilder;

@Service
public class LeadSquardService {

  private final Logger LOGGER = LoggerFactory.getLogger(this.getClass());

  @Value("${leadsquard.accesskey}")
  private String access_key;

  @Value("${leadsquard.secretkey}")
  private String serect_key;

  /**
   * Create a New User in Lead Capture.
   * @param leadCapture
   * */
  public void createNewUserInLeadCapture(LeadCapture leadCapture) {

    MultiValueMap<String, String> mapdata = new LinkedMultiValueMap<>();
    mapdata.add("FirstName", leadCapture.getFirstName());
    mapdata.add("Phone", "");
    mapdata.add("EmailAddress", leadCapture.getEmailAddress());
    mapdata.add("mx_Courses", leadCapture.getMx_courses());


    UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl("hostUrl");
    builder.queryParam("accessKey" , access_key );
    builder.queryParam("secretKey", serect_key);


    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_JSON);
    //headers.set("Accept", MediaType.APPLICATION_JSON_VALUE);

    try {
      HttpEntity<MultiValueMap<String,String>> requestEntity = new HttpEntity<>(mapdata, headers);


      RestTemplate restTemplate = new RestTemplate();
      ResponseEntity<String> response = restTemplate.exchange(builder.build().toUriString(), HttpMethod.POST, requestEntity, String.class);

      HttpStatus statusCode = response.getStatusCode();
      if (statusCode == HttpStatus.ACCEPTED) {

        System.out.println("ResponseEntity : " + response.getBody());
      }
    } catch (Exception e) {
        e.printStackTrace();
    }
  }
}

I'm thinking that you can't use HttpEntity<MultiValueMap<String, String>> to create a JSON request.

See if this recent topic helps you out: https://coderanch.com/t/730462/java/HTTP-POST-java-process-throwing

A "500" error is a server-side error. You should have a stack trace and we need to see it before we can offer much in the way of help.

It's only throw 500 internal error

[Paul Clapham]

I don't know what you mean by "internal error".

If you use Ajax to submit something to the server, and it comes back with a 500 status code, then that means that an error occurred on the server. So if that's what happened to you, then you have to look on the server to find out what the error was. Or if it's not your server, then you need to contact the people who manage the server and ask them to work with you to find the problem.
