I have a page that displays the list of all the journals available. I want to write a thymeleaf expression language that highlights the already subscribed journals using there journal id . So for all the subscribed journals the text for the hyper-link href should be "Unsubscribe" and vice verse if its not subscribed.

Controller
#Controller
public class SubscriptionController {
#Autowired
private SubscriberService subscriberService;
#RequestMapping(value = "/subscribe", method = RequestMethod.POST)
String subscribe(Model model, #RequestParam("journalId") Integer journalId) {
JournalToken token = (JournalToken) SecurityContextHolder.getContext().getAuthentication();
Account user = (Account) token.getCredentials();
model.addAttribute("user", user);
Journal journal = this.subscriberService.findJournalById(journalId);
this.subscriberService.subscribeJournalForSubscriber(journal, user);
return "redirect:subscriptions";
}
#RequestMapping(value = "/subscriptions", method = RequestMethod.GET)
String list(Model model) {
JournalToken token = (JournalToken) SecurityContextHolder.getContext().getAuthentication();
Account user = (Account) token.getCredentials();
model.addAttribute("user", user);
ArrayList<Journal> journals = this.subscriberService.FindAllJournals();
model.addAttribute("journals", journals);
StringBuilder sub = new StringBuilder();
ArrayList<Subscription> subscribed = this.subscriberService.getSubscribedJournalsForSubscriber(user);
model.addAttribute("subscriptions", subscribed);
return "subscriptions";
}
}
Model subscriptions
#Entity
#Table(uniqueConstraints={#UniqueConstraint(columnNames={"userId", "journalId"})})
public class Subscription {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
#Version
private Integer version;
private Integer userId;
private Integer journalId;
public void setId(Integer id) {
this.id = id;
}
public Integer getId() {
return this.id;
}
public void setVersion(Integer version) {
this.version = version;
}
public Integer getVersion() {
return this.version;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public Integer getUserId() {
return this.userId;
}
public void setJournalId(Integer journalId) {
this.journalId = journalId;
}
public Integer getJournalId() {
return this.journalId;
}
}
you can change your arrayList subscribed to have only the ids of journals (more optimised).
So, in the controller you can have something like this
ArrayList<Integer> subscribed =
this.subscriberService.getSubscribedJournalsForSubscriber(user); //modify it so it returns the journals ids instead of the whole object(Subscription)
then in the thymeleaf change the anchor with something like this
<a id="href" th:href="'javascript:subscribe(\'' + ${journal.id} + '\');'">
<span th:if="${#lists.contains(subscriptions, journal.id) }" th:text="Unsubscribe"> Unsubscribe </span>
<span th:if="not ${#lists.contains(subscriptions, journal.id) }" th:text="Subscribe"> Subscribe </span>
</a>
Have a look at the documentation of thymeleaf http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html
/*
* Check if element or elements are contained in list

${#lists.contains(list, element)}

Intro:
My app works in the general sense. All as I want. But when I set up validation (and it does work), it won't load all my hidden content. I moved it all to its own page, and it still did not work. So I am asking here with my original set up. I understand it is messy, but I will clean it up once I figure this out.
I can't find anything related to my problem, which makes me think, the way that I am doing it might not be the best approach. So pointers are more than welcome.
Problem:
Adding Validation to my forms breaks my Thymeleaf template. Unable to hide and unhide elements. It looks stuck. But on the terminal, the program does run fine.
My controller
(it's big... I still need to learn how to break it in smaller chunks.)

I moved the content I was hiding to its own page. It loads the page, but the content remains hidden. Even after taking a break I am still unable to find what is wrong. Specially when it works 100% without validation.
I'm trying to add data in table via server but unable to succeed. I tried many things but nothing worked. I'm getting the data from the server but unable to populate that in table.. can someone please help me out?
I'm getting this :
"DataTables warning: table id=particlarsTable - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1"
Let me explain my code first:
(In View)
When I click on "Add New Particular" button, bootstrap modal will popup with input fields, those fields will send to the server then again back to view and populate the table with the same data without refreshing the whole page.
I'm stuck on the last stage, I'm getting the data on UI/View in ajax success handler but unable to load that data in table.
here is my view :
<form class="form-horizontal" method="post" id="createAdHocForm">
<div class="row">
<div class="col-md-3">
<div class="form-group">
<label>Select Flat</label>
<select asp-for="AdHocInvoice.FlatRid" asp-items="#(new SelectList(Model.Flats,"FlatRid","FlatNumber"))" class="form-control form-control-sm selectpicker" data-live-search="true">

Action Method on controller:
public JsonResult AddParticular(string particular, decimal amount)
{
_flatInvoiceViewModel.AdHocInvoice.FlatInvoiceItems.Add(new FlatInvoiceItem { Particular = particular, Amount = amount });
return Json(_flatInvoiceViewModel);
}
Class/Model:
public class FlatInvoiceItem
{
public Guid FlatInvoiceItemRid { get; set; }
public Guid FlatInvoiceRid { get; set; }
public Guid FundRuleRid { get; set; }
public string Particular { get; set; }
public decimal Amount { get; set; }
}
NOTE: this code is in initial phase, I need that input data on server for further process(will add code later) so don't want to use $.('#table_body_id').append("<tr>..</tr>"); type of code.
1.Firstly,reload() is used to send request back to the method which display the DataTable initially(e.g. name this method Test).
2.Secondly,From your AddParticular method,you just add a data to the list but the lifetime is just one request,so when you reload to Test method,the list still contains the initial data without new data.
Conclusion: I suggest that you could save data to database.And get data from database.
Here is a working demo about how to use DataTabale:
1.Model:
public class Test
{
public int Id { get; set; }
public AdHocInvoice AdHocInvoice { get; set; }

You need to have test for your classes controllers, repositories and services. Your builder is fine, your controller should like something like
#SpringBootTest
public class ProductControllerTest {
#InjectMocks
private ProductController productController;
#Mock
private ProductService productService;
#Mock
private BindingResult bindingResult;
private Model model;
private Product productOptional;
private List<Product> products;
private Product product;
#Before
public void setUp() {
MockitoAnnotations.initMocks(this);
this.productOptional = ProductBuilder.mockProductBuilder().getProduct();
this.products = (List<Product>) ProductBuilder.mockCollectionProductBuilder().getProducts();
this.product = ProductBuilder.mockProductBuilder().getProduct();
this.model = new ConcurrentModel();
}
#Test
public void index() {
Mockito.when(this.productService.searchAll()).thenReturn(this.products);
Assert.assertEquals(this.productController.index(this.model), "product/index");
Assert.assertEquals(this.model.containsAttribute("products"), true);
}
#Test
public void create() {
Assert.assertEquals(this.productController.add(product, this.model), "product/addProduct");
}
#Test
public void update() {
Mockito.when(this.productService.searchById((long) 1)).thenReturn(this.productOptional);
Assert.assertEquals(this.productController.edit((long) 0, this.model), "product/editProduct");
Assert.assertEquals(this.model.containsAttribute("product"), false);
}
#Test
public void save() {
Mockito.when(this.productService.inserir(this.product)).thenReturn(this.product);
Mockito.when(this.bindingResult.hasErrors()).thenReturn(true);
Assert.assertEquals(this.productController.save(this.product, this.bindingResult, this.model), "product/addProduct");
}
#Test
public void saveError() {
Mockito.when(this.productService.inserir(this.product)).thenReturn(this.product);
Mockito.when(this.bindingResult.hasErrors()).thenReturn(true);
Assert.assertEquals(this.productController.save(this.product, this.bindingResult, this.model), "product/addProduct");
}
#Test
public void delete() {
Assert.assertEquals(this.productController.delete((long) 1, this.model), "product/index");
Mockito.verify(this.productService, Mockito.times(1)).deletar((long) 1);
}
}
For repositories
#RunWith(SpringRunner.class)
#SpringBootTest
public class ProductRepositoryTest {
#Autowired
private ProductRepository productRepository;
private Product product;
#Before
public void setUp() {
this.product = ProductBuilder.mockProductBuilder().getProduct();
}
#After
public void after() {
this.productRepository.deleteAll();
}
#Test
public void findAll() {
Assert.assertThat(this.productRepository.findAll(), instanceOf(List.class));
}
#Test
public void findById() {
Assert.assertThat(this.productRepository.findById((long) 2), instanceOf(Optional.class));
}
#Test
public void saveCreate() {
this.product.setId((long) 1);
this.product = this.productRepository.save(this.product);
//Assert.assertNotEquals(this.product.getId(), 1);
}
#Test
public void saveUpdate() {
this.product.setId((long) 0);
this.product = this.productRepository.save(this.product);
this.product.setNome("Jonas");
Product productAtualizado = this.productRepository.save(this.product);
Assert.assertEquals(productAtualizado.getNome(), this.product.getNome());
}
#Test
public void deleteById() {
this.product = this.productRepository.save(this.product);
this.productRepository.deleteById(this.product.getId());
Assert.assertEquals(this.productRepository.findAll().size(), 0);
}

My page doesn’t open. On this page I can create a user and give him a username and password + role (admin or user). Why does page doesn t work. You can look at the code, it seems to have written correctly. Maybe somewhere I made a mistake in the code.Tomcat gives error 404. I just need him to open this page, you can see the controller

Change URL to admin/addUser
because in your controller you have added a root level admin
#RequestMapping("/admin")
ex .http://localhost:8080/SchoolMaven/admin/addUser
I am trying to bind the input type checkbox using spring form controller,But i failed .
Here i am posting Controller,bean and jsp example,One more thing is i can't use
.
Below is the code:
Controller:
package com.test.web;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.SimpleFormController;
import com.vaannila.domain.User;
import com.vaannila.service.UserService;
#SuppressWarnings("deprecation")
public class UserController extends SimpleFormController {
private UserService userService;
public UserController() {
setCommandClass(User.class);
setCommandName("user");
}
public void setUserService(UserService userService) {
this.userService = userService;
}
#Override
protected ModelAndView onSubmit(Object command) throws Exception {
User user = (User) command;
user.setCommunity(user.getCommunity());
userService.add(user);
return new ModelAndView("userForm","user",user);
}
}
jsp:
<%# page language="java" contentType="text/html; charset=ISO-8859-1"

Java beans:
package com.test.domain;
public class User {
private String name;
private String password;
private String gender;
private String country;
private String aboutYou;
private String[] community;
private Boolean mailingList;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {

}
public void setPassword(String password) {
this.password = password;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getCountry() {
return country;
}
public void setCountry(String country) {
this.country = country;
}
public String getAboutYou() {
return aboutYou;
}
public void setAboutYou(String aboutYou) {
this.aboutYou = aboutYou;
}
public String[] getCommunity() {
return community;
}
public void setCommunity(String[] community) {
this.community = community;
}
public Boolean getMailingList() {
return mailingList;
}
public void setMailingList(Boolean mailingList) {
this.mailingList = mailingList;
}
}
I tried different ways,but no luck.Any hints please.
the browser will not send the field in the request if the checkbox isn't checked. the value will either be "true" or not sent. you will never get a "false" value.
add a hidden field with _name for every checkbox
EX:
<input type="checkbox" name="community" value="Hibernate"/>
<input type="hidden" name="_community" value="on"/>
Then, spring will take care of it.
If you do not use the form tag it will not automaticly bind your checkboxes. If you use plain html you have to bind the your self.
You can solve this by adding a list of community objects and then use form:checkboxes.
For example:
<form:checkboxes path="communityList" items="${communityList}" itemValue="key" itemLabel="value" />
I would also recomend you to use a HashMap when using ModelAndView like this:
Map<String, Object> model = new HashMap<String, Object>();
model.put("user", user);
model.put("communityList", communityList);
return new ModelAndView("userFormat", model);
Manually bind using 'ServletRequestUtils'... http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/web/bind/ServletRequestUtils.html
Example
public ModelAndView test(HttpServletRequest request, HttpServletResponse response) throws ServletRequestBindingException {
Long subscriptionOwnerId = ServletRequestUtils.getLongParameter(request, "id");
return new ModelAndView('test'); }`
