So I have the following Model:
#Entity
#Table(name = "Project")
public class Project implements java.io.Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "PROJECT_ID", unique = true, nullable = false)
private int projectId;
private String name;
...
#ManyToOne
#JoinColumn(name = "MANAGER_ID")
#NotEmpty(message = "test")
private User manager;
....
}
For some reason the "#NotEmpty" annotation gives the following error when
the input is blank:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is javax.validation.UnexpectedTypeException: HV000030: No validator could be found for type: com.springmvc.model.User.
I am passing my values to the backend the following way:
<form:select path="manager" class="selectpicker form-control">
<form:option value="" >Alle managers</form:option>
<c:forEach var="manager" items="${managers}">
<form:option value="${manager.userId}" >${manager.getUserDetail().firstName}
${manager.getUserDetail().lastName}</form:option>
</c:forEach>
</form:select>
What am I doing wrong?
Replace #NotEmpty with #NotNull, that should fix your problem.

}
ModelAndView mv = new ModelAndView("redirect:list");
return mv;

What am I doing wrong?
You most likely need to build a converter class such as this one :
#Component("facilityConverter")
public class FacilityConverter implements Converter<String, Facility>
{
#Autowired
FacilityService facilityService;
#Override
public Facility convert(String id)
{
return facilityService.findById(Integer.parseInt(id));
}
}
Then, you need to register it by implementing the addFormatters method inside of a configuration class implementing WebMvcConfigurer like so :
#Override
public void addFormatters (FormatterRegistry registry)
{
registry.addConverter((FacilityConverter)ctx.getBean("facilityConverter"));
}
Your entities will then correctly be mapped from a dropdown selection. Also, this might not be part of your issue but you can just build your dropdowns like this :
<form:select name="linkedInterface" path="linkedInterface" id="linkedInterface">
<form:options items="${interfaces}" itemLabel="name" itemValue="id"/>
</form:select>
The productId field is actually a Product object, not an ID (String/int). You need your JSP to use path="productId.id" rather than path="productId".
(Although I'd also suggest you also rename the field product rather than productId.)
<form:select path="product.id">
I think you'll hit the same issue on your <form:select path="client"> too.
i have problem with pass object(CarType) in spring input form.
My Car model:
#Entity
#Table(name="CAR")
public class Car implements Serializable{
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name = "CAR_ID", unique=true, nullable=false)
private long id;
#NotEmpty
#Column(name = "REG_NO", nullable=false)
private String regNo;
#NotEmpty
#Column(name = "YEAR", nullable=false, length = 4)
private String year;
#Column(name = "AVAILABLE", nullable=false)
private boolean available = true;
#Column(name = "START_DATE")
private String startDate;
#Column(name = "RETURN_DATE")
private String returnDate;
#OneToOne
#JoinColumn(name="CAR_TYPE_ID")
private CarType carType;
//getters and setters
Car Type model:
#Entity
#Table(name = "CAR_TYPE")
public class CarType {
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name = "CAR_TYPE_ID", unique=true, nullable=false)
private int id;
#NotEmpty
#Column(name = "MARK", nullable=false)
private String mark;
#NotEmpty
#Column(name = "MODEL", nullable=false)
private String model;
//getters and setters
Controllers:
#RequestMapping(value = { "/rent-car-{regNo}" }, method = RequestMethod.GET)
public String rentCar(#PathVariable String regNo, ModelMap model) {
Car car = carService.findCarByRegNo(regNo);
model.addAttribute("car", car);
return "rentcar";
}
#RequestMapping(value = { "/rent-car-{regNo}" }, method = RequestMethod.POST)
public String saveRentCar(#Valid Car car, BindingResult result, ModelMap model) {
carService.updateCar(car);
model.addAttribute("success", "Car " + car.getRegNo() + " rented successfully");
return "registrationsuccess";
}
JSP file
<form:form method="POST" modelAttribute="car" class="form-horizontal">
<form:input type="hidden" path="id" id="id"/>
<form:input type="hidden" path="year" id="year"/>
<form:input type="hidden" path="regNo" id="regNo"/>

<form:input type="hidden" path="carType" id="carType"/>
<form:input type="text" path="startDate" id="startDate"/>
<form:input type="text" path="returnDate" id="returnDate"/>
I have problem with that code
<form:input type="hidden" path="carType" id="carType"/>
how can i pass object CarType to Car form? I always have that same error: column 'CAR_TYPE_ID' cannot be null. It looks like I'm transferring a null CarType to Car. I dont know why?
Someone can help me? In registercar.jsp i used converter (convert regNo to class CarType) and its works.
You need to know how the Car object gets bound in the Controller handler method from http request from the client. Spring MVC maps the the request parameters to contruct the Car object. Hence the CarType is an associated object. You need to provide a minimal clue to Spring MVC to construct that for you.
<form:form method="POST" action="/rent-car${regNo}" modelAttribute="car">
......
<form:input type="hidden" path="carType.id"/>
<form:input type="hidden" path="carType.model"/>
<form:input type="hidden" path="carType.mark"/>
<input type="submit" value="Submit"/>
</form:form>
you will find a complementary example here is this article Spring MVC - Binding Request Parameters and Path Variables to Java Backing Objects
I looking for help in understanding how to create a new object through a form which has the user select multiple sub-objects (which will come pre-populated) and available to select with a checkbox.
OrderController.java
#RequestMapping(value = { "/order" }, method = RequestMethod.GET)
public String order(ModelMap model) {
List<Exam> exams = examService.findAllExams();
List<Document> documents = documentService.findAllDocuments();
model.addAttribute("exams", exams);
model.addAttribute("documents", documents);
return "order"; // jsp page reference
}
Order.java
#Entity
#Table(name="\"order\"")
public class Order implements Serializable
{
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name = "order_id", unique = true, nullable = false)
private Integer id;
#GeneratedValue(generator = "uuid")
#GenericGenerator(name = "uuid", strategy = "uuid2")
#Column(name = "uuid", unique = true, nullable = false)
private String uuid;
#Temporal(TemporalType.DATE)
#Column(name = "order_date", unique = true, nullable = false)
private Date orderDate;

#JoinColumn(name = "user_id", nullable = false)
private User user;
#OneToMany(fetch = FetchType.LAZY, mappedBy = "order")
private Set<OrderExam> orderExams = new HashSet<OrderExam>(0);
#OneToMany(fetch = FetchType.LAZY, mappedBy = "order")
private Set<OrderDocument> orderDocuments = new HashSet<OrderDocument(0);
//getters & setters
}
OrderExam.java
#Entity
#Table(name="order_exam")
public class OrderExam implements Serializable
{
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy=GenerationType.IDENTITY)
#Column(name = "order_exam_id", unique = true, nullable = false)

private Exam exam;
#Column(name="exam_amount", nullable=true)
private Integer examAmount;
#Column(name="answer_sheet_amount", nullable=true)
private String answerSheetName;
#Column(name="students_per_csv", nullable=true)
private String studentsPerCSV;
#Column(name="pas", nullable=true)
private Boolean pearsonAnswerSheet;
//getters & setters
}
Exam.java
#Entity
#Table(name="exam")
public class Exam implements Serializable
{
private static final long serialVersionUID = 1L;
#Id

private String code;
#OneToMany(fetch = FetchType.LAZY, mappedBy = "exam")
private Set<OrderExam> exams = new HashSet<OrderExam>(0);
//getters & setters
}
As you can see I am passing in a list of exams and documents which will populate a form with available options (can be seen in the image below (exams anyway)). The user needs to be able to select multiple rows, so that a single order has multiple exams and documents associated to it.
My order.jsp is a little much to post the entire thing here but here is the part I have which is displayed in the image above.
Order.jsp
<form:form method="POST" modelAttribute="order" class="form-horizontal form-label-left">
<c:forEach items="${exams}" var="exam">
<tr>
<th scope="row"><input type="checkbox" class="flat"></th>
<td><input id="middle-name" type="text" name="middle-name" readonly="readonly" value="${exam.name} - ${exam.code}" class="form-control col-md-7 col-xs-12"></td>
<td><input id="middle-name" type="text" name="middle-name" value="0" class="form-control col-md-3 col-xs-12"></td>
<td><input id="middle-name" type="text" name="middle-name" value="0" class="form-control col-md-3 col-xs-12"></td>
<td><input id="middle-name" type="text" name="middle-name" value="0" class="form-control col-md-3 col-xs-12"></td>
<c:choose>
<c:when test="${exam.name == 'Algebra 2 (Common Core)'}">
<th scope="row"><input type="checkbox" class="flat"></th>
</c:when>
<c:otherwise>
<th scope="row"></th>
</c:otherwise>
</c:choose>
</tr>
</c:forEach>
<!-- Other Stuff Goes Here -->
</form:form>
So in short, would someone be willing to show me how to set up the form in the way I described above? Thanks in advance.
Your question is a bit broad however you could try this as below. I have only covered exams. Principal for documents will be the same.
You will need a couple of new classes to capture the submitted form inputs:
Order Form to Capture Selections
public class OrderForm{
private List<ExamWrapper> allAvailableExams = new ArrayList<>();
private XOptionPrintWrapper selectedWrapper;
public OrderForm(){
}
//getters and setters
}
Exam Wrapper : Decorates an Exam with a 'selected' property
public class ExamWrapper{
private boolean selected;
private Exam exam;
public ExamWrapper(Exam exam){
this.exam = exams;
}
//getters and setters
}
Change Contoller to
public class OrderController{
//Exams model populated by the method below
//moved as we also need it populated on POST
#RequestMapping(value = { "/order" }, method = RequestMethod.GET)
public String order(ModelMap modelMap) {
//only needed on GET so put in model here
List<XOptionPrintWrapper> availableWrappers = //someList;
modelMap.put("availableWrappers", availableWrappers);
return "order";
}
//handles for submit
//model atribute is automatically populated by the framework
#RequestMapping(value = { "/order" }, method = RequestMethod.POST)
public String order(#ModelAttribute("orderForm") OrderForm orderForm) {
//process selected exams
return "nextView";
}
//on get populates the initial model for display
//on post create an instance which the form params will be bound to
#ModelAttribute("orderForm")
public OrderForm getOrderForm(){
OrderForm orderForm = new OrderForm();
List<Exam> exams = examService.findAllExams();
for(Exam exam : exams){
orderForm.getAllAvailableExams.add(new ExamWrapper(exam));
}
return orderForm;
}
}
In JSP use Sping support for binding to indexed properties:
<form:form method="POST" modelAttribute="orderForm" class="form-horizontal form-label-left">
<c:forEach items="${orderForm.allAvailableExams}" var="exam" varStatus="status">
<tr>
<th scope="row"><input name="allAvailableExams[${status.index}].selected"
type="checkbox" class="flat"></th>
</tr>
</c:forEach>
<form:select path="selectedWrapper">
<form:options items="${availableWrappers}"
itemValue="somePropertyOfXOptionPrintWrapper "
itemLabel="somePropertyOfXOptionPrintWrapper " />
</form:select>
</form>
I obviously haven't been able to try all of this but think it should all be okay.
Im new with Spring, and Iam having this exception.
I have a jsp, with many selects. All of them work fine, but one show this exception:
org.apache.jasper.JasperException: Ha sucedido una excepción al procesar la página JSP /WEB-INF/pages/nuevo-expediente.jsp en línea 45
42: <td>

Im implementing the selct same way others which are working fine. Here the jsp code:
<tr>
<td>Expediente padre:</td>
<td>
<form:select path="expedientePadre.codExpediente">
<form:option value="-" label="Seleccione un expediente"/>
<form:options items="${expedientes}" itemLabel="codExpediente" itemValue="codExpediente"/>
</form:select>
<form:errors path="expedientePadre" element="span"/>
</td>
</tr>
Here the controller:
#RequestMapping(value = "nuevo-expediente")
public String createExpedienteGet(Model model) {
model.addAttribute("expediente", new Expediente());
model.addAttribute("expedienteP", new Expediente());
List<TipoResolucion> resoluciones = service.getResoluciones();
List<TipoExpediente> listaTipos = service.getTipos();
List<EstadoExpediente> listaEstados = service.getEstados();
List<Expediente> listaExpedientes = service.getExpedientes();
List<TipoRelacion> listaRelaciones = service.getRelaciones();
List<CanalExpediente> listaCanales = service.getCanales();
List<IdiomaExpediente> listaIdiomas = service.getIdiomas();
model.addAttribute("resoluciones", resoluciones);
model.addAttribute("tipos", listaTipos);
model.addAttribute("estados", listaEstados);
model.addAttribute("expedientes", listaExpedientes);
model.addAttribute("tiposRelacion", listaRelaciones);
model.addAttribute("canales", listaCanales);
model.addAttribute("idiomas", listaIdiomas);
return "nuevo-expediente";
}
#RequestMapping(value = "nuevo-expediente", method = RequestMethod.POST)
public String createExpedientePost(#ModelAttribute("expediente") Expediente expediente, BindingResult result) {
service.createExpediente(expediente);
return "redirect:expedientes";
}
here, the entity Expediente:
#Entity
#Table(name="Expediente")
public class Expediente implements Serializable {
#Id
#Column(length = 15)
private String codExpediente;
#ManyToOne(cascade={CascadeType.ALL})
#JoinColumn(name = "tipoExpediente")
private TipoExpediente tipoExpediente;

#Temporal(javax.persistence.TemporalType.TIMESTAMP)
private Date fechaCierre;
public String getCodExpediente() {
return codExpediente;
}
public void setCodExpediente(String codExpediente) {
this.codExpediente = codExpediente;
}
............................
............................
And finally the TipoExpediente Entity
package com.atlantis.atecliente.model;
import java.io.Serializable;
import javax.persistence.*;
#Entity
#Table
public class TipoExpediente implements Serializable {
#Id
#Column(length = 40)
private String tipo;
public String getTipo() {
return tipo;
}
public void setTipo(String tipo) {
this.tipo = tipo;
}
}
I think it could happen because the expedientePadre property, is a foreign key to the same entity Expediente, but I dont know resolve it...
Some help? Thanks!
I think the problem is that your class TipExpediente class does not have getter or setter methods for the property codExpedient. Spring is looking at your TipoExpediente class and expecting it to have the property you outlined in the JSP.
I'd like someone could explication about converter in spring mvc.
My domain class:
#Entity
#Table(name = "TIME_SHEET")
public class TimeSheet implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
#Column(name = "ID_TIME_SHEET")
private Long id;
#NotNull(message = "timesheet.cadastro.horainicio.obrigatorio")
#Temporal(TemporalType.TIME)
#Column(name = "INICIO", nullable = false)
private Date horaInicio;
#NotNull(message = "timesheet.cadastro.horafim.obrigatorio")
#Temporal(TemporalType.TIME)
#Column(name = "FIM", nullable = false)
private Date horaFim;
#Column(name = "LATITUDE", nullable = true)
private Double latitude;
#Column(name = "LONGITUDE", nullable = true)
private Double longitude;
#Size(max = 300,message = "timesheet.cadastro.observacao.acimaDoPermitido")
#Column(name = "OBSERVACAO", nullable = true)
private String observacao;
//#NotNull(message = "timesheet.cadastro.dia.obrigatorio")
#ManyToOne(cascade = javax.persistence.CascadeType.ALL)
#JoinColumn(name = "ID_DIAS")
private Dias dia;
//#NotNull(message = "timesheet.cadastro.usuario.obrigatorio")
#ManyToOne(cascade = javax.persistence.CascadeType.ALL)
#JoinColumn(name = "ID_USUARIO")
private Usuario usuario;
...
My class converter:
public class IdToUsuarioConverter implements Converter<String, Usuario> {
#Autowired
private IusuarioService usuarioService;
public Usuario convert(String id) {
return usuarioService.buscaPorId(Long.valueOf(id));
}
}
In my springmvc.xml:
<mvc:annotation-driven conversion-service="conversionService"/>
<bean id="conversionService"
class="org.springframework.context.support.ConversionServiceFactoryBean">
<property name="converters">
<set>
<bean class="br.com.infowhere.timeSheet.converter.IdToUsuarioConverter"/>
</set>
</property>
</bean>
I don't have problem, but my question is:
1-) When my converter will act ?
2-) My .jsp will post a form where I have one list similar:
<form:select path="user" items="${userList}" multiple="false" />
HTML:
<select id="user" name="user">
<option value="1">User 1</option>
<option value="2">User 2</option>
</select>
At what time my converter will work ?
I'm sorry but I'm trying to understand about converter.
thanks !!!
Your converter will convert id's to Usario objects in your controllers.
For example:
#Controller
public class MyController {
#RequestMapping("/showUsario")
public String showUsario(#RequestParam("id") Usario usario, Model model) {
model.addAttribute("usario", usario);
return "showUsario";
}
}
Then a request to /showUsario?id=123 will convert String "123" to Usario using the converter. If you didn't have a converter you would have to put String id (instead of Usario) in method parameters and manually convert the id to Usario. This way, Spring does it for you using your converter.
