path="userRoles" is multi select field. Which is populated with the method "initializeRoles()" from the controller. I have a converter also to convert Roles to UserRoles object. When I submit the form even after selecting all the Roles, I get only the first selected one always to the converter class as shown below. Why I am not getting String[] from JSP?
Output in the Converter class:
1

Added one more converter class for String[]. Then I started getting multiple values which were selected in in UI. Why I have to write two Converter classes. Is there a way to combine both the classes.
public class UserRolesConverter1 implements Converter<String[], List<UserRoles>> {
...
#Override
public List<UserRoles> convert(String[] roles) {

I am getting this error when I run my Project and I tried all the fixes online but it did not work.

Thanks in advance for the help
what is the right way to solve LocalDateTime error?
I am new to spring therefore I have tried to look for the way to solve this online but I cannot get around it.
This is my entity
package com.reserve.entities;
import java.time.LocalDateTime;
import java.util.Date;
import javax.persistence.Column;
import javax.persistence.Entity;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.format.annotation.DateTimeFormat.ISO;
#Entity
public class Flight extends AbstractEntity {
private String flightNumber;
private String operatingAirlines;
private String departureCity;
private String arrivalCity;
#DateTimeFormat(iso=ISO.DATE)
private Date dateOfDeparture;
#Column(name="estimatedDepartureTime",columnDefinition="TIMESTAMP")
private LocalDateTime estimatedDepartureTime;
public String getFlightNumber() {
return flightNumber;
}
public void setFlightNumber(String flightNumber) {
this.flightNumber = flightNumber;
}
public String getOperatingAirlines() {
return operatingAirlines;
}
public void setOperatingAirlines(String operatingAirlines) {
this.operatingAirlines = operatingAirlines;
}
public String getDepartureCity() {
return departureCity;
}
public void setDepartureCity(String departureCity) {
this.departureCity = departureCity;
}
public String getArrivalCity() {
return arrivalCity;
}
public void setArrivalCity(String arrivalCity) {
this.arrivalCity = arrivalCity;
}
public Date getDateOfDeparture() {
return dateOfDeparture;
}
public void setDateOfDeparture(Date dateOfDeparture) {
this.dateOfDeparture = dateOfDeparture;
}
public LocalDateTime getEstimatedDepartureTime() {
return estimatedDepartureTime;
}
public void setEstimatedDepartureTime(LocalDateTime estimatedDepartureTime) {
this.estimatedDepartureTime = estimatedDepartureTime;
}
#Override
public String toString() {
return "Flight [flightNumber=" + flightNumber + ", operatingAirlines=" + operatingAirlines + ", departureCity="
+ departureCity + ", arrivalCity=" + arrivalCity + ", dateOfDeparture=" + dateOfDeparture
+ ", estimatedDepartureTime=" + estimatedDepartureTime + "]";
}
}
This is my controller.
I am not sure which information is required.
Please let me know if there are more information that could help.

You can try to use Spring The Formatter SPI to convert Date expressed as String to LocalDateTime and vice versa.
public class DateTimeFormatters {
public static class LocalDateTimeFormatter implements Formatter<LocalDateTime> {
#Override
public LocalDateTime parse(String pattern, Locale locale) throws ParseException {
return LocalDateTime.parse(pattern, DateTimeFormatter.ISO_LOCAL_DATE_TIME);
}
#Override
public String print(LocalDateTime object, Locale locale) {
return object.format(DateTimeFormatter.ISO_LOCAL_DATE_TIME);
}
}
}
And register your Formatter e.g
public class ApplicationConfig implements WebMvcConfigurer {
...
#Override
public void addFormatters(FormatterRegistry registry) {
registry.addFormatter(new DateTimeFormatters.LocalDateTimeFormatter());
}
...
}
I was trying to send the posts to DB. However,when I tried to use themeleaf, it shows me the following error:

First of all your controller should contain get method which returns Student object as a form to bind. You missed that. It should look something like this:
#RequestMapping(value={"/StudentForm"},method=RequestMethod.GET)
public ModelAndView studentForm() {
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("student", new Student()) //returns object to thymeleaf context
modelAndView.setViewName("StudentForm");
return modelAndView;
}
then you should change your naming convention in your student class, fields should start with lower case. You should notice that you have field Name in your Student class but you want to map th:field="*{name}" in thymeleaf view.
Read something about DTO and Models because you shouldn't use your entities directly in controller layer
This is my Controller class

#GetMapping(value="/user")
public String getUser(Model model){
model.addAttribute("user", new User());

}
#PostMapping(value="/user")
public String postUser(#ModelAttribute("user") User user){

in controller user object does not bind the data into address model object.
output is user :user[name="name",address[]]
Your form seems to only manage one adress, but your domain model specifies a list of adresses. In this case you would need to name your input fields like address[0].street for the first address and so on.
So I'd consider to use a thymleaf iterator (th:each) to make all addresses manageable in your form. Then use th:field instead of defining name attributes. This should solve your problem.
<form class="form-horizontal" th:action="#{/user}" method="POST" th:object="${user}">
<div class="form-group">
<label for="inputDescription" class="col-sm-2 control-label">Full Name</label>

I am trying to submit the form and send the data to the post method of my controller, but all i get is status 400 error I am not able to understand why this error is poping when i am able to submit for the post method for the different JSP pages.
