весенний mvc формирует преобразование боба из строки в длинный

0 голосов
/ 18 февраля 2012

У меня очень простой крет.Он состоит из компонента, представляющего данные формы.У меня есть поле с длинным значением.В JSP я пишу это: <form:hidden path="id"/>.Когда я отправляю форму, я получаю сообщение об ошибке HTTP Status 400.

Короче, когда отправка длинного значения, пружина mvc не может преобразовать его в long для создания объекта формы.

поток прост: пользователь нажимает кнопку «Редактировать над электронной компанией».Контроллер через службу извлекает компанию, затем отображается представление, и, наконец, пользователь отправляет изменения ... но когда длинное значение передается, я получил ошибку.

Отладочная информация говорит мне об этом: 

DefaultHandlerExceptionResolver [DEBUG] Resolving exception from handler [public java.lang.String ar.com.held.controller.CompanyController.edit(java.lang.Long,org.springframework.ui.Model)]: org.springframework.beans.TypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.lang.Long'; nested exception is java.lang.NumberFormatException: For input string: "save"

вот код:

мой бин формы: 

public class CompanyForm {

    private Long id;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    @NotBlank
    private String name;
    @NotBlank
    private String addressStreet;
    @NotBlank
    private String addressCity;
    @NotBlank
    private String addressState;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddressStreet() {
        return addressStreet;
    }

    public void setAddressStreet(String addressStreet) {
        this.addressStreet = addressStreet;
    }

    public String getAddressCity() {
        return addressCity;
    }

    public void setAddressCity(String addressCity) {
        this.addressCity = addressCity;
    }

    public String getAddressState() {
        return addressState;
    }

    public void setAddressState(String addressState) {
        this.addressState = addressState;
    }

}

мой контроллер: 

@RequestMapping(value={"edit/{companyId}"})
    public String edit(@PathVariable Long companyId, Model model){
        CompanyForm form = new CompanyForm();
        if(companyId!=null){
            Company company = companyService.find(companyId);
            if(company!=null)
                modelMapper.map(company, form);
        }
        model.addAttribute("form", form);
        return "company/edit";
    }

    @RequestMapping(value={"new"})
    public String edit(Model model){
        return this.edit(null, model);
    }

    @RequestMapping(value="save", method={RequestMethod.POST})
    public String save(@ModelAttribute("form") @Valid CompanyForm companyForm, BindingResult result){
        if(result.hasErrors())
            return "company/edit";
        Company company;
        if(companyForm.getId()!=null)
            company = companyService.find(companyForm.getId());
        else
            company = new Company();
        modelMapper.map(companyForm, company);
        companyService.save(company, getLoggedUser());
        return "redirect:list";
    }

мой jsp: 

<form:form method="post" action="save" modelAttribute="form" cssClass="form-horizontal" >
        <fieldset>

            <form:hidden path="id"/>
            ++++  others fields +++
            <div class="form-actions">
                <input type="submit" value="Guardar" class="btn btn-primary btn-large"/>
            </div>
        </fieldset>
    </form:form>

Ну, проблема была здесь:

, когда я редактирую компанию, я указываю на / companies / edit / {id} 

<form:form method="post" action="save" modelAttribute="form" cssClass="form-horizontal" >

, поэтому, когда я отправляю формуURL выглядит так: / companies / edit / save и мой контроллер ожидает /companies/save..

, поэтому я должен указать абсолютный путь для атрибута action в теге формы.Как здесь: 

<form:form method="post" action="${pageContext.request.contextPath}/companies/save" modelAttribute="form" cssClass="form-horizontal" >

и проблема решена .. это была проблема URL.
