Question

我是百老汇的新手......有人可以告诉你百事可乐和弹簧控制器之间的价值观是如何传递的......请为thymeleaf-spring-mvc建议好的教程......

在下面的示例中，请让我知道用户在文本字段中输入所有者的值是如何传递给spring控制器的，以便验证并返回结果。反之，控制器返回的结果如何由百万美元来显示结果。如何知道LASTNAME的值对于控制器..如何将它传递给控制器owner.getLastName（）的所有者对象..

        <div class="control-group" id="lastName">

@RequestMapping（value =“/ owners”，method = RequestMethod.GET） public String processFindForm（Owner owner，BindingResult result，Model model）{

    // allow parameterless GET request for /owners to return all records
    if (owner.getLastName() == null) {
        owner.setLastName(""); // empty string signifies broadest possible search
    }

    // find owners by last name
    Collection<Owner> results = this.clinicService.findOwnerByLastName(owner.getLastName());
    if (results.size() < 1) {
        // no owners found
        result.rejectValue("lastName", "notFound", "not found");
        return "owners/findOwners";
    }
    if (results.size() > 1) {
        // multiple owners found
        model.addAttribute("selections", results);
        return "owners/ownersList";
    } else {
        // 1 owner found
        owner = results.iterator().next();
        return "redirect:/owners/" + owner.getId();
    }
}

假设您有一个控制器方法，如：

void method-name(Owner owner){
    // ...
}

单击提交按钮时，值会自动设置为域类，然后创建新方法并设置对象的模型属性 model.addAttribute("owner",new Owner);
