我有一个页面来获取所有字段及其关系数据。

我想要实现的是插入包，然后插入它的相关内容。

我该怎么做？如果有什么遗漏，请评论一下，我必须补充一下。

显示形式控制器

代码语言：javascript
运行
复制
@GetMapping("/add-tour-package")
public String showAddPackageForm(Model model) {
    TourPackage tourPackage = new TourPackage();
    Itinerary itinerary = new Itinerary();
    model.addAttribute("tourPackage", tourPackage);
    model.addAttribute("itinerary", itinerary);
    return "new-tour-package";
}

插入旅游套餐

代码语言：javascript
运行
复制
@PostMapping("/save-tour-package")
public String saveTourPackage(@ModelAttribute("tourPackage") TourPackage tourPackage, @ModelAttribute("itinerary") Itinerary itinerary) {
    // save package to database
    tourPackageService.saveTourPackage(tourPackage);
    return "redirect:/";
}

具有动态字段的表单。请注意，行程是动态输入字段，因此将有多个行程。

代码语言：javascript
运行
复制
<form th:action="@{/save-tour-package}" th:object="${tourPackage}" method="POST">
        <div class="form-group">
            <div class="form-group">
                <label for="title">Title</label>

在做tourPackageService.saveTourPackage(tourPackage);之前，只需为tourPackage：tourPackage.setItineraries(itinerary);设置行程。确保您对日程安排(在tourPackage.setItineraries(itinerary);之前)做了相同的操作：

itinerary.forEach(项目-> { item.setTourPackage(tourPackage)；}

那就做tourPackageService.saveTourPackage(tourPackage)；
