java - 从前一个 Controller 重定向时未调用 Post 方法

标签 java spring-mvc jsp spring-boot servlets

所以我有 3 个 jsp 表单。第一个包含一般信息。完成第一个表单后，它应该基于下拉列表的值返回表单 2 或表单 3。到目前为止，对象已正确写入数据库，执行检查并显示正确的 jsp 表单，但当用户填写第二个表单时，没有任何反应，读取第二个表单的 postmethod 未调用。 任何有关如何解决此问题的提示将不胜感激。 我已经绞尽脑汁在互联网上搜索了好几天，但找不到直接的答案。

通用 Controller :

@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;
}
}

最佳答案

例如在返回中传递完整的 URL

return "http://localhost:8080/projectname/"+url;
