无法使用TH：thymeleaf字段

Question

我正在尝试开发一个带有spring boot的项目，它将被员工用于休假或休假，我也将crud操作用作Rest web服务，但是我在thymeleaf的th：字段中遇到了一个问题，它会生成错误:org.thymeleaf.exceptions.templateProcessingException：在执行处理器'org.thymeleaf.spring5.processor.springInputGeneralFieldTagProcessor'（模板：“admin/home”-第81行，第54列）期间出错，下面可以找到控制器的代码和html

@GetMapping("/application")
public String applicationForm(Model model) {
    model.addAttribute("application", new Application());
    return "home";
}

@RequestMapping(value="/application", method=RequestMethod.POST)
public String applicationSubmit(@ModelAttribute Application application, Model model, BindingResult bindingResult, MultipartHttpServletRequest request) throws IOException {
    if (bindingResult.hasErrors()) 
        return "home";

    model.addAttribute("application", application);

    return "result";
}

<form action="#" th:action="@{'createApplication'}" th:object="${application}" method="post">

            Description: <input type="text" id="description" th:field="*{description}"/>    
            From Date: <input type="text" id="from" th:field="*{fromDate}" />
            To Date: <input type="text" id="to" th:field="*{toDate}"/>

            <button type="submit" class="btn btn-primary">Submit</button>

            </form>

Answer 1

使用此应用程序类。当不能从thymeleaf访问字段（它们不是公共的或没有公共访问权限（getters/setters））时，会发生此异常。

public class Application {
private String description;
private String fromDate;
private String toDate;

public String getDescription() {
    return description;
}

public void setDescription(String description) {
    this.description = description;
}

public String getFromDate() {
    return fromDate;
}

public void setFromDate(String fromDate) {
    this.fromDate = fromDate;
}

public String getToDate() {
    return toDate;
}

public void setToDate(String toDate) {
    this.toDate = toDate;
}

}
