Answer 1

我认为这与您从控制器返回联系人的事实有关。默认视图解析器正在查找适合的HTML文件以显示结果。您是否尝试返回响应正文实体或指向某种视图页面？

Answer 2

您似乎向“/logicalideasJPA/contacts.html”发送了请求，但没有处理此请求的控制器。

@Controller
@RequestMapping("/contacts")
public class ContactController {

@Autowired
private ContactsImp serviceInter;

@RequestMapping(method = RequestMethod.GET)
public String showContactForm(Map<String, Contacts> map){
    Contacts contacts = new Contacts();
    map.put("contacts", contacts);
    return "contacts";
}

通过上述更改，您的请求应在/ contacts uri

处理

警告：org.springframework.web.servlet.PageNotFound - 找不到带URI的HTTP请求的映射
