我正在关注这个问题---> Spring MVC:如何执行验证?
这是我的控制器代码
@RequestMapping(value = "saveBankDetails.htm", method = RequestMethod.POST)
public ModelAndView saveBankDetails(ModelMap model ,@Valid @ModelAttribute("SpringWeb")BankDetails bean,
BindingResult result){
System.out.println(result.hasErrors());
System.out.println(bean.getNoOfBankDetails());
System.out.println(bean.getBankDetails().get(0).getNameOfBank());
if(result.hasErrors())
{
return new ModelAndView("error/error", "command",new String());
}
else{
return new ModelAndView("bankDetails/bankDetails", "command",bean);
}
}
BankDetails bean 包含 EntityBankDetails 的 ArrayList。我已将验证应用于 EntityBankDetail 的字段,如图所示
public class EntityBankDetail {
@NotNull
@Size(max = 3)
private String nameOfBank;
private Double EMIforProposedLoan;
private String nameOfBranch;
private String accountType;
private String accountNumber;
private String applicantType;
//Getters and Setters
}
我在 BankDetail 字段中输入超过 3 个字符,以便我在控制台上获得控制器的输出为
false
3

为什么我的验证不起作用?我做错了什么?请指教..
编辑以包含 BankDetailBean
/*
* This class represent the entire Bank Details Page. It can contain 0-4 EntityBankDetais
* */
public class BankDetails {
private ArrayList<EntityBankDetail> bankDetails;
private String[] entities;
@Size(max = 1)
private int noOfBankDetails;
public ArrayList<EntityBankDetail> getBankDetails() {
return bankDetails;
}
public void setBankDetails(ArrayList<EntityBankDetail> bankDetails) {
this.bankDetails = bankDetails;
}
public String[] getEntities() {
return entities;
}
public void setEntities(String[] entities) {
this.entities = entities;
}
public int getNoOfBankDetails() {
return noOfBankDetails;
}
public void setNoOfBankDetails(int noOfBankDetails) {
this.noOfBankDetails = noOfBankDetails;
}
}
我在这个 bean 上收到错误,无法解析 Class EntityBankDetail 键入。两者都在同一个包中,为什么会这样??
