Question

我的问题与此问题非常相似：Spring MVC Multiple Controllers with same @RequestMapping

我正在使用Spring Boot构建简单的人力资源Web应用程序。我有一份工作清单和每个工作的个人网址：

本地主机：8080 /作业/ 1

此页面包含作业发布详细信息和未经身份验证的用户 - 申请人（在这种情况下）可用于应用此作业的表单。经过身份验证的用户-HR Manager-只能查看发布详细信息，而不能查看表单。我在验证表单输入方面遇到了麻烦。

我先尝试了什么：

@Controller
public class ApplicationController {

    private final AppService appService;

    @Autowired
    public ApplicationController(AppService appService) {
        this.appService = appService;
    }

    @RequestMapping(value = "/jobs/{id}", method = RequestMethod.POST)
    public String handleApplyForm(@PathVariable Long id, @Valid @ModelAttribute("form") ApplyForm form, BindingResult bindingResult) {
        if (bindingResult.hasErrors()) {
            return "job_detail"; //HTML page which contains job details and the application form
        }
        appService.apply(form, id);
        return "redirect:/jobs";
    }

    @RequestMapping(value = "/applications/{id}", method = RequestMethod.GET)
    public ModelAndView getApplicationPage(@PathVariable Long id) {
        if (null == appService.getAppById(id)) {
            throw new NoSuchElementException(String.format("Application=%s not found", id));
        } else {
            return new ModelAndView("application_detail", "app", appService.getAppById(id));
        }
    }
}

你猜这不起作用，因为我无法得到模型。所以我将handleApplyForm()添加到JobController并进行了一些更改：

@Controller
public class JobController {

    private final JobService jobService;
    private final AppService appService;

    @Autowired
    public JobController(JobService jobService, AppService appService) {
        this.jobService = jobService;
        this.appService = appService;
    }

    @RequestMapping(value = "/jobs/{id}", method = RequestMethod.POST)
    public ModelAndView handleApplyForm(@PathVariable Long id, @Valid @ModelAttribute("form") ApplyForm form, BindingResult bindingResult) {
        if (bindingResult.hasErrors()) {
            return getJobPage(id);
        }

        appService.apply(form, id);
        return new ModelAndView("redirect:/jobs");
    }

    @RequestMapping(value = "/jobs/{id}", method = RequestMethod.GET)
    public ModelAndView getJobPage(@PathVariable Long id) {
        Map<String, Object> model = new HashMap<String, Object>();

        if (null == jobService.getJobById(id)) {
            throw new NoSuchElementException(String.format("Job=%s not found", id));
        } else {
            model.put("job", jobService.getJobById(id));
            model.put("form", new ApplyForm());
        }

        return new ModelAndView("job_detail", model);
    }
}

通过这种方式，验证可以正常工作，但我仍然无法获得与刷新页面相同的效果here，以便所有有效输入都消失，并且不会显示错误消息。

顺便说一句，job_detail.html是这样的：

<h1>Job Details</h1>
<p th:inline="text"><strong>Title:</strong> [[${job.title}]]</p>
<p th:inline="text"><strong>Description:</strong> [[${job.description}]]</p>
<p th:inline="text"><strong>Number of people to hire:</strong> [[${job.numPeopleToHire}]]</p>
<p th:inline="text"><strong>Last application date:</strong> [[${job.lastDate}]]</p>

<div sec:authorize="isAuthenticated()">
    <form th:action="@{/jobs/} + ${job.id}" method="post">
        <input type="submit" value="Delete this posting" name="delete" />
    </form>
 </div>

<div sec:authorize="isAnonymous()">
    <h1>Application Form</h1>
    <form action="#" th:action="@{/jobs/} + ${job.id}" method="post">
        <div>
            <label>First name</label>
            <input type="text" name="firstName" th:value="${form.firstName}" />
            <td th:if="${#fields.hasErrors('form.firstName')}" th:errors="${form.firstName}"></td>
        </div>

        <!-- and other input fields -->

        <input type="submit" value="Submit" name="apply" /> <input type="reset" value="Reset" />
    </form>
</div>

检查百里叶文件here

th：field属性的值必须是选择表达式（* {...}），

此外，ApplyForm已曝光，您可以在表单中捕获它。

然后您的表单应如下所示：

<form action="#" th:action="@{/jobs/} + ${job.id}" th:object="${applyForm}" method="post">
        <div>
            <label>First name</label>
            <input type="text" name="firstName" th:value="*{firstName}" />
            <td th:if="${#fields.hasErrors('firstName')}" th:errors="*{firstName}"></td>
        </div>

        <!-- and other input fields -->

        <input type="submit" value="Submit" name="apply" /> <input type="reset" value="Reset" />
</form>

Spring Boot具有相同映射的多个控制器
