所以我有3种jsp形式。第一个带有一般信息。在完成第一个表格后，它应该基于下拉返回eather表格2或表格3的值。到目前为止，到目前为止，已正确将对象写入db，执行了检查并显示了正确的jsp表格，但是，当用户填写第二个表单时，什么也没有发生，因此不会调用第二个表单的后方法。 任何有关如何解决此问题的技巧将不胜感激。 我已经折腾了头，在互联网上搜索了几天，但找不到直接的答案。
GeneralController：
@Controller
public class GeneralController {
@Autowired
private GeneralRepo repo;
@GetMapping("new")
public String getNew(Map<String, Object> model) {
WrapperClass wrapper = new WrapperClass();
model.put("wrapperForm", wrapper);
return "newRecord";
}
@PostMapping("new")
public String handlePost(@ModelAttribute("wrapperForm") WrapperClass wrapper)
{
Address address = new Address(wrapper.getNameOrg(), wrapper.getStreet(), wrapper.getNumber(), wrapper.getZip(),
wrapper.getCity(), wrapper.getTelephone(), wrapper.getEmail());
General general = new General(wrapper.getLanguage(), wrapper.getApplication(), wrapper.getNameKbo(), wrapper.getKboNumber(),
address, wrapper.getApplicationType(), wrapper.getNotes(), null, null, null, null);
String url;
if (general.getApplicationType().equalsIgnoreCase("voortzetting")) {
url = "invoices";
} else {
url = "employee";
}
repo.save(general);
return "redirect:/" + url;
}
}

例如在返回值中传递完整的URL
return "http://localhost:8080/projectname/"+url;
