I have three fields department_Id,department_Name,department_location in departmentForm act as a model object in this model form.
I have use annotation to validate the fields. Now, I want to only use two fields in different jsp page say create.jsp and one field in different jsp page say getDepartmentById.
When I press submit button of create.jsp, validation is happening but after providing correct information its not submitted cause in this page.
I haven't give one field department_Id which is auto generated by my DAO layer. So, please help me, how to reject this value to execute my create.jsp page for successfully creating department in database.
When I printed the BindingResult object, it shown as follow:
Field error in object 'departmentForm' on field 'departmentId': rejected value [null];
codes [NotEmpty.departmentForm.departmentId,NotEmpty.departmentId,NotEmpty.java.lang.String,NotEmpty];
arguments [org.springframework.context.support.DefaultMessageSourceResolvable:
codes [departmentForm.departmentId,departmentId]; arguments [];
default message [departmentId],org.hibernate.validator.constraints.NotEmpty.message},
[Ljava.lang.Class;#4fc4a198,[Ljava.lang.Class;#764d2b11];
default message [may not be empty]`
This is how I coded in controller:
#RequestMapping(value = "/createDepartment", method = RequestMethod.POST)
public String createEmployee(#Valid DepartmentForm departmentForm,
BindingResult bindingResult, Map<String, DepartmentForm> model)
throws Exception {
if (bindingResult.hasErrors()) {
System.out.println(bindingResult);
bindingResult.reject(departmentForm.getDepartmentId());
return "departmentForm";
}
System.out.println("mr ankur jadiy");
model.put("departmentForm", departmentForm);
departmentForm.setUpdateStatus('A');
if (departmentForm.getUpdateStatus() == 'A') {
departmentServiceImpl
.actionDecider(convertDeptFormToDeptBO(departmentForm));
}
return "Success";
}
my DepartmentForm code is as follow:
package com.nousinfo.tutorial.model;
import javax.validation.constraints.Size;
import org.hibernate.validator.constraints.NotEmpty;
public class DepartmentForm {
#NotEmpty
#Size(min = 1, max = 20,message="")
private String departmentId;
#NotEmpty
private String departmentName;
private String departmentLocation;
private Character updateStatus;
public String getDepartmentId() {
return departmentId;
}
public void setDepartmentId(String departmentId) {
this.departmentId = departmentId;
}
public String getDepartmentName() {
return departmentName;
}
public void setDepartmentName(String departmentName) {
this.departmentName = departmentName;
}
public String getDepartmentLocation() {
return departmentLocation;
}
public void setDepartmentLocation(String departmentLocation) {
this.departmentLocation = departmentLocation;
}
public Character getUpdateStatus() {
return updateStatus;
}
public void setUpdateStatus(Character updateStatus) {
this.updateStatus = updateStatus;
}
}
and my create.jsp is

What the error says is that you're missing value for departmentId, which is not surprising since you defined it as
#NotEmpty
#Size(min = 1, max = 20,message="")
You don't really need to validate departmentId if it's autogenerated by your code. You probably should remove it from the DepartmentForm, especially since it's not in the form, or at least make it optional.
You can make it mandatory in your business object, but the form backing object should reflect what's in the form.
update
If departmentId is a database-generated id, you should set it as disallowed in your controller's InitBinder:
#InitBinder
public void initBinder(WebDataBinder binder) {
binder.setDisallowedFields(new String[] { "departmentId" });
}

I entered
Quotation cluster (" "): 1
Quotation Exclamation cluster ("!"): 2
And some text for phrases.
Like this:
The problem:
To createPost quotationCluster and quotationExclamationCluster came as zeroes.
But I entered 1 and 2 respectively.
Could you help me understand what I have don wrongly and correct the situation.
Change
<input type="number" id="quotation-cluster"
name="quotation-cluster" th:value="${quotationCluster}"/>
To:
<input type="number" id="quotation-cluster" th:field="*{questionCluster}"
name="quotationCluster" th:value="${quotationCluster}"/>
the name and th:field should be same as the declared attribute in your java class CorePhraseForm. Repeat this for the the next input (Textarea).
I have 2 tables, city and hotel_details in my database. I am trying to fetch the data from these tables and populating inside a form for registering the customer. But I am getting "java.lang.IllegalStateException: Neither BindingResult nor plain target object for bean name 'command' available as request attribute" as error.

When you use <form:form> attribute, it requires you to specify model object that should be bound to form tag. If you don't specify any model attribute default name is used as command.
Following is the description of form:form tag from spring-form.tld -
<attribute>
<description>Name of the model attribute under which the form object is exposed.
Defaults to 'command'.</description>
<name>modelAttribute</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
<attribute>
<description>Name of the model attribute under which the form object is exposed.
Defaults to 'command'.</description>
<name>commandName</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
</attribute>
As you don't have any model object bound to form, try removing form:form tag and use HTML form tag and also make sure you match input parameter names with method parameter names. i.e -
<form action="search">
...
</form>
I am working with spring mvc and i want to know how get a hashset from a checkbox
Muy problem is that the checkbox return null
In your controller class, in any method, you need to populate hashset in Model and use it page.
For e.g.
#Controller
#RequestMapping("/member.htm")
public class MemberController {
#RequestMapping(method = RequestMethod.GET)
public String initForm(Model model) {
Member member = new Member();
Set<String> data = new HashSet<String>();
courses.add("Yoga");
courses.add("Stretching");
courses.add("Pilates");
courses.add("Aerobic");
courses.add("Oriental");
model.addAttribute("courses", courses);
return "member";
}
}
Use spring-taglib for use HashSet like:
<%# taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
<html>
<title>Spring MVC checkbox</title>
</head>
<body>
<h2>Subscribe to the gym</h2>
<form:form method="POST" commandName="member">
<table>
<tr>
<td>Choose the courses you like:</td>
<td><form:checkboxes path="courses" items="${courses}" />
</td>
</tr>
<tr>
<td><input type="submit" name="submit" value="Submit"></td>
</tr>
<tr>
</table>
</form:form>
</body>
</html>
This has been asked a few times but all of them did not answer my question. I have been trying to get different functionalities to work with Thymeleaf for two days now and been very unsuccessful. I have only been able to get it to work with spring-boot, however right now I am using spring-MVC.
First I will show you my dependencies
<%# taglib prefix="sf" uri="http://www.springframework.org/tags/form" %>
<%# page contentType="text/html;charset=UTF-8" language="java" %>
<html xmlns:th="http://www.thymeleaf.org" xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Create a New Account</title>
<link th:href="#{/resources/css/loginForm.css}" href="/resources/css/loginForm.css" rel="stylesheet"
type="text/css"/>
</head>
<body>
<form action="#" th:action="#{/createNewAccount}" th:object="${user}" method="post">
<table>
<tr>
<td>Name:</td>
<td><input type="text" th:field="*{username}" /></td>
<td th:if="${#fields.hasErrors('name')}" th:errors="*{username}">Name Error</td>
</tr>
<tr>
<td>Password:</td>
<td><input type="text" th:field="*{password}" /></td>
<td th:if="${#fields.hasErrors('age')}" th:errors="*{password}">Password Error</td>
</tr>
<tr>
<td><button type="submit">Submit</button></td>
</tr>
</table>
</form>
</body>
</html>
Now so you can see the errors my intellij IDE is showing:
User.java
package com.practice.domain;
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
/**
* Created by DrewJocham on 8/30/15.
*/
public class User {
#NotNull
#Size(min = 2, max = 30)
private String username;
#NotNull
private String password;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
#Override
public String toString() {
return "User{" +
"username='" + username + '\'' +
", password='" + password + '\'' +
'}';
}
}
The field name you call hasErrors with needs to match the field name in the object. Like so:
<td th:if="${#fields.hasErrors('username')}" th:errors="*{username}">Name Error</td>
Note that hasErrors('name') became hasErrors('username'), and:
<td th:if="${#fields.hasErrors('password')}" th:errors="*{password}">Password Error</td>
Note that hasErrors('age') became hasErrors('password').
As for the errors being highlighted in Intellij, I think they're misleading, and are related to this open issue: https://youtrack.jetbrains.com/issue/IDEA-132738
I searched everywhere for this error and looked through every single thread here with the same title, changed a lot in my code but still, the error is there.
it says:
HTTP Status 400 -
type Status report
message
description The request sent by the client was syntactically incorrect.
Apache Tomcat/7.0.35
My Controller code is:
#RequestMapping(value = "/manageInventory.htm", method = RequestMethod.GET)
public ModelAndView manageInventory(HttpSession session) {
ArrayList<Product> products = new ArrayList<Product>();
Manufacturer manufacturer = (Manufacturer) manufacturerDAO
.getByUsername(((UserAccount) session.getAttribute("user"))
.getUsername());
products = productDAO.getProductListByManufacturer(manufacturer
.getManufacturerName());
System.out.print(products.get(0).getProductName());
ModelAndView view = new ModelAndView("manageInventory");
view.addObject("products", products);
InventoryItem inventoryItem = new InventoryItem();
view.addObject("inventoryItem", inventoryItem);
return view;
}
#RequestMapping(value = "/manufacture.htm", method = RequestMethod.POST)
public ModelAndView manufactureProduct(HttpSession session, BindingResult result,
#ModelAttribute("inventoryItem") #Valid InventoryItem inventoryItem) {
System.out.print(result.getErrorCount()+" "+result.getAllErrors());
ModelAndView view = null;
if(!result.hasErrors())
{
Manufacturer manufacturer = manufacturerDAO
.getByUsername(((UserAccount) (session.getAttribute("user")))
.getUsername());
inventoryItem.setAvailability(true);
inventoryItem.setManufacturer(manufacturer);
manufacturer.getInventory().add(inventoryItem);
manufacturerDAO.update(manufacturer);
view = new ModelAndView("done");
}
else
{
view = new ModelAndView("manageInventory");
}
return view;
}
The first method adds inventoryItem into the model and I am fetching that for validations afterwards.
I am using tiles so,My tile for this is:
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%# taglib uri="http://www.springframework.org/tags/form" prefix="form"%>
<body>

</form:form>

My POJO has the following validation:
#NotNull
private int quantity;
Please help. Thanks in advance.
I forgot to add HttpServletRequest request to the method input parameters.
I added it and it stared working. strange, but worked. :)
