I am using Spring and Thymeleaf templates. What I am trying is, to show a customer's addresses within a Thymeleaf template (using Bootstrap tabs) in a many-to-one relation.
I can't get the addresses to show up or add new ones. Any help is appreciated!
customerAddressform.html (Thymeleaf)

What I want to do
I aim to change the value of added todo from false to true after entering a check on checkbox provided next to each todo and then click the done-button.
I aim to show todos of which value is true.(true means 'done')
Does anyone know how to fix this?
I couldn't find the way to fix this and I’m so badly stuck at this task.

Firstly I figured out couple of codes that can cause serious performance issues and is not advised.
Here's a few:
Take off your Generated Getters and Setters and Leave the annotation #Getter and #Setter to do the work.
Take off <input type="hidden" th:field="*{add_id}" /> as it will be auto-generated from your entity Address private Long add_id
Take off address.toString() from your saveAddress controller as this is not needed to parse data to your Entity, your entity receives String already which will be parsed from your form, there is no need to convert with toString again.
One of your error states Failed to convert from type [java.lang.String] to type [java.lang.Long] which simply means you're trying to convert Long to String which should be auto generated by your Entity
I hope this helps!!!

return wholePrice;
}
public void setWholePrice(Double wholePrice) {
this.wholePrice = wholePrice;
}
}
I have replaced this:
List<Product> product = new ArrayList<>();
List<State> state = new ArrayList<>();
model.addAttribute("product", product);
model.addAttribute("state", state);
by this:
Product product = new Product();
State state = new State();
model.addAttribute("product", product);
model.addAttribute("state", state);```
now it works. Thank you.
I am trying to implement Hibernate+Spring Validation to my application,but there is one issue, it won't display error message on page after I submit faulty data. Here is code:
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
public class StudentVO {
private int studentID;
private String userName;
#NotNull
#Size(min=2, max=45, message="Your Name should be between 2 - 45 characters.")
private String firstName;
private String middleName;
#NotNull
#Size(min=2, max=45, message="Your Surname should be between 2 - 45 characters.")
private String lastName;
JSP
<form:form id="myform" modelAttribute="student" method="post" class="form-horizontal" action="/register/registerStudent">
<div class="form-group">
<label for="firstname" class="col-sm-3 control-label">First Name</label>
<div class="col-sm-6">
<form:input type="text" class="form-control float_left" id="firstname" path="firstName" placeholder="First Name" />
<form:errors path="firstName"></form:errors>
</div>
</div>
<div class="form-group">
<label for="middlename" class="col-sm-3 control-label" id="md">Middle Name</label>
<div class="col-sm-6">
<form:input type="text" class="form-control" id="middlename" path="middleName" placeholder="Middle Name" />
</div>
</div>
<div class="form-group">
<label for="lastname" class="col-sm-3 control-label">Last Name</label>
<div class=" col-sm-6">
<form:input type="text" class="form-control float_left" id="lastname" path="lastName" placeholder="Last Name" required="true" />
<form:errors path="lastName"></form:errors>
</div>
Controller
#RequestMapping(value = { "/register/registerStudent" }, method = { RequestMethod.GET, RequestMethod.POST })
public String registerSubmit(#Valid StudentVO student, BindingResult result, Model model, HttpServletRequest request,
#RequestParam String action, #RequestParam(value = "parentID", required = false) String parentID,
#RequestParam(value = "studentID", required = false) String studentID,
RedirectAttributes redirectAttributes) {
if(result.hasErrors()){
model.addAttribute("student", student);
List<Map<String, String>> age = lookupService.getFields("age");
model.addAttribute("age", age);
return "studentSignup";
}
Thanks for help!
I found problem in my registerSubmit method I didn't mention #ModelAttribute, so code for method should look like:
#RequestMapping(value = { "/register/registerStudent" }, method = { RequestMethod.GET, RequestMethod.POST })
public String registerSubmit(#Valid #ModelAttribute StudentVO student, BindingResult result, Model model, HttpServletRequest request,
#RequestParam String action, #RequestParam(value = "parentID", required = false) String parentID,
#RequestParam(value = "studentID", required = false) String studentID,
RedirectAttributes redirectAttributes) {
if(result.hasErrors()){
model.addAttribute("student", student);
List<Map<String, String>> age = lookupService.getFields("age");
model.addAttribute("age", age);
return "studentSignup";
}
