title: Springboot + Thymeleaf: Failure by parsing a template
body: <p>i want to show a requested object in HTML and i get a Error and i have no idea what cause my error. Google could not help and now i try to ask you. I don't think the Error comes from my Table, because i commented it out and the error still occour. The Error also not come from &quot;http://localhost:8081/simulation&quot; because i reseive a valid JSON with valid values. Thanks for helping :).</p>
  <p>Here is my Code:</p>
  <p>ApiController.java:</p>
  <pre><code>package de.WI18C.Gruppe5.API.controller;
  import de.WI18C.Gruppe5.API.model.Unternehmen;
  import org.springframework.stereotype.Controller;
  import org.springframework.ui.Model;
  import org.springframework.web.bind.annotation.*;
  import org.springframework.web.client.RestTemplate;
  
  @Controller
  public class APIContoller {
  
  @RequestMapping(value = &quot;/unternehmen&quot;, method = RequestMethod.GET)
  public String viewUnternehmen(Model model) {
      RestTemplate restTemplate = new RestTemplate();
      Unternehmen unternehmen = restTemplate.getForObject(&quot;http://localhost:8081/simulation&quot;, Unternehmen.class);
      model.addAttribute(&quot;unternehmen&quot;, unternehmen);
  
      return &quot;unternehmen&quot;;
     }
  }
