There was an unexpected error (type=Internal Server Error, status=500). class java.lang.String cannot be cast to class com.app.inventory.model.Product

Hello comunity I need your help with a problem in my proyect, i need to add details in the database at the same time, I have been researching how to do, I found the solution is using a iterator or a bucle for, When I use the bucle obvious I need to use arrays, I did it, But I have a object, i did the conversion (cast), but when i add the details at the web i can't because appears this error
Basically the error is the program can't cast a String to Object(Class)

Convert String to Money Thymeleaf

I am having a problem converting input String to money. I am creating a spring boot application with thymeleaf. I have a web page where user inputs the data and there is a particular field where he inputs the String and it needs to be converted to type joda.money as in my pojo class that field has money data type. This is a full governor_form.html:
<!DOCTYPE html>

<form th:action="#{/governors/save}" method="post" th:object="${governor}" style="max-width: 550px; margin: 0 auto;">

</div>
<script type="text/javascript">

This is where he inputs that data:
<div class="form-group row">
<label class="col-sm-4 col-form-label">Per Capita Income</label>
<div class="col-sm-8">
<input type="number" step="0.01" th:field="*{perCapitaIncome}" class="form-control" required>
</div>
</div>
So if i'm not mistaken Hibernate is having a problem converting a String input from thymeleaf to type money as I get the following error:
: Resolved [org.springframework.validation.BindException: org.springframework.validation.BeanPropertyBindingResult: 1 errors<EOL>Field error in object 'governor' on field 'perCapitaIncome': rejected value [1100]; codes [typeMismatch.governor.perCapitaIncome,typeMismatch.perCapitaIncome,typeMismatch.org.joda.money.Money,typeMismatch]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [governor.perCapitaIncome,perCapitaIncome]; arguments []; default message [perCapitaIncome]]; default message [Failed to convert property value of type 'java.lang.String' to required type 'org.joda.money.Money' for property 'perCapitaIncome'; Cannot convert value of type 'java.lang.String' to required type 'org.joda.money.Money' for property 'perCapitaIncome': no matching editors or conversion strategy found]]
This is the joda.money dependency:
<dependency>

<artifactId>joda-money</artifactId>

This is a POJO class:

How do I convert String to Money?

One solution would be to create custom deserilizer for Money field, and then use Jackson to set it.
Here is code snippet:
MoneyDeserializer.java :
public class MoneyDeserializer extends StdDeserializer<BigMoney> {
private static final long serialVersionUID = 2518470236548239933L;
public MoneyDeserializer() {
super(Money.class);
}
#Override
public BigMoney deserialize(final JsonParser jp, final DeserializationContext ctxt) throws IOException, JsonProcessingException {
return BigMoney.of(CurrencyUnit.USD, jp.readValueAs(Double.class));
}
}
Governor.java
import com.example.demo.filter.MoneyDeserializer;
import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import org.joda.money.BigMoney;
import org.joda.money.Money;
import java.io.Serializable;
public class Governor implements Serializable {
private Integer idGovernor;
private String fullName;
private Integer age;
private String position;
private java.sql.Date dateOfIntercession;
private java.sql.Date dateOfResignation;
private BigMoney perCapitaIncome;
private Integer populationBelowPoverty;
public Integer getIdGovernor() {
return this.idGovernor;
}
public void setIdGovernor(Integer idGovernor) {
this.idGovernor = idGovernor;
}
public String getFullName() {
return this.fullName;
}
public void setFullName(String fullName) {this.fullName = fullName;}
public Integer getAge() {
return this.age;
}
public void setAge(Integer age) {
this.age = age;
}
public String getPosition() {
return this.position;
}
public void setPosition(String position) {
this.position = position;
}
public java.sql.Date getDateOfIntercession() {
return this.dateOfIntercession;
}
public void setDateOfIntercession(java.sql.Date dateOfIntercession) {
this.dateOfIntercession = dateOfIntercession;
}
public java.sql.Date getDateOfResignation() {
return this.dateOfResignation;
}
public void setDateOfResignation(java.sql.Date dateOfResignation) {
this.dateOfResignation = dateOfResignation;
}
public BigMoney getPerCapitaIncome() {
return this.perCapitaIncome;
}
#JsonDeserialize(using = MoneyDeserializer.class)
public void setPerCapitaIncome(BigMoney perCapitaIncome) {
this.perCapitaIncome = perCapitaIncome;
}
public Integer getPopulationBelowPoverty() {
return this.populationBelowPoverty;
}
public void setPopulationBelowPoverty(Integer populationBelowPoverty) {
this.populationBelowPoverty = populationBelowPoverty;
}
#Override
public String toString() {
return "Governor{" +
"idGovernor=" + idGovernor +
", fullName='" + fullName + '\'' +
", age=" + age +
", position='" + position + '\'' +
", dateOfIntercession=" + dateOfIntercession +
", dateOfResignation=" + dateOfResignation +
", perCapitaIncome=" + perCapitaIncome +
", populationBelowPoverty=" + populationBelowPoverty +
'}';
}
}
NOTE: On your form, you are passing age field as Double, but in your class it's declared as Integer. So you will get exception during deserilization process.
Same thing applys for populationBelowPoverty field . Also, your date format is dd/MM/YYYY and I think this is not supported format for jackson. It should be YYYY-MM-dd.
Anyway, for example, if you send a JSON like this:
{
"idGovernor":1,
"fullName":"Test",
"age":1,
"dateOfIntercession":"2022-06-09",
"dateOfResignation":"2022-06-17",
"perCapitaIncome":"123.932",
"position":"position",
"populationBelowPoverty":"98"
}
to this controller method:
#PostMapping(value = "/test/governor")
public Governor testGovernor(#RequestBody Governor governor) {
return governor;
}
You should get response like this :
{
"idGovernor": 1,
"fullName": "Test",
"age": 1,
"position": "position",
"dateOfIntercession": "2022-06-09",
"dateOfResignation": "2022-06-17",
"perCapitaIncome": {
"amount": 123.932,
"zero": false,
"negative": false,
"positive": true,
"amountMajorLong": 123,
"negativeOrZero": false,
"amountMinorLong": 12393,
"amountMinor": 12393,
"positiveOrZero": true,
"minorPart": 93,
"scale": 3,
"amountMinorInt": 12393,
"currencyUnit": {
"code": "USD",
"numericCode": 840,
"decimalPlaces": 2,
"symbol": "$",
"numeric3Code": "840",
"countryCodes": [
"PR",
"MP",
"IO",
"FM",
"PW",
"GU",
"BQ",
"TC",
"VG",
"AS",
"VI",
"TL",
"UM",
"MH",
"EC",
"US"
],
"pseudoCurrency": false
},
"currencyScale": false,
"amountMajorInt": 123,
"amountMajor": 123
},
"populationBelowPoverty": 98
}
In your case, since you are using thymeleaf you can adjust this idea to your needs.

Adding image to mysql database doesn't work

Validation failed for object='auctionItem'

When trying to submit my form to create a new auction this error appears in the browser:
Whitelabel Error Page:
This application has no explicit mapping for /error, so you are seeing
this as a fallback.
Thu Mar 30 21:00:15 BST 2017
There was an unexpected error (type=Bad Request, status=400)
Validation failed for object='auctionItem'. Error count: 2
I can't seem to find any specific errors within my log, so I am having trouble finding the two validation errors show on the error page. I am pretty lost at this point. Hopefully someone can help me out, its preventing me from making progress at the moment.

Maybe you missed " BindingResult " in Controller.

BindingResult userloginResult)

Updated:
I could resolve the problem with removing enctype="multipart/form-data" at edit.jspx. But it raised another issue, how if I'm going to upload file?

Add #ModelAttribute annotation to your model object parameter in the controller method that you're calling, so that Spring knows that's the object that you want to bind the form data to.
/*
* Update a survey request

#RequestMapping(value = "/{id}", params = "form", method = RequestMethod.POST)
public String update(#ModelAttribute("surveyRequest") SurveyRequest surveyRequest,
BindingResult bindingResult, Model uiModel,
