私は非常にシンプルな分類をしています。フォームデータを表すBeanで構成されています。私は長い価値のあるフィールドを持っています。 jspで私はこれを書く：<form:hidden path="id"/>。フォームを送信すると、HTTPステータス400エラーが表示されます。spring mvc form bean文字列から文字列への変換
短い値で提出すると、mvcはフォームオブジェクトを構築するためにlongに変換できません。
フローは単純です：ユーザはe社で編集をクリックします。サービスを介してコントローラが会社を取得し、次にビューがレンダリングされ、最終的にユーザーが変更をサブミットします。しかし、長い値がサブミットされたときにエラーが発生しました。
デバッグ情報は、この私に語った：ここ
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"
コードは次のとおりです。
私のフォームBean：
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;
}
}
私のコントローラ：
@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";
}
私のjsp ：
