How to remove multiple rows via checkbox

I am new to spring and I need to be able to delete the selected rows by checkbox. How can I delete multiple rows from the database? I am using Thymeleaf as view.
Here is my code:
HTML
<div class="col-md-12">
<table class="table" id="tableImport">
<thead>
<tr>
<th scope="col">Remove</th>
<th scope="col">Debt Age Rule</th>
<th scope="col">Reminder</th>
<th scope="col">Frequency</th>
<th scope="col">Reorder</th>
</tr>
</thead>
<tbody>
<tr th:each="configCampaign:${listConfigCampaigns}">
<td>
<input type="checkbox" name="my-checkbox">
</td>
<td th:text="${configCampaign.debtagerule}"></td>
<td th:text="${configCampaign.remindebttype}"></td>
<td th:text="'Every '+${configCampaign.every} + ' ' + ${configCampaign.unit}"></td>
<td></td>
</tr>
</tbody>
</table>
<div class="col-md-12" style="text-align: center">
<input class="btn btn-primary" type="button" value="- Remove Selected Action(s)"/>
</div>
</div>
This table shows me data from an arrayList in memory, nothing with a database, I need to remove those selected objects from the array. At the moment I have my controller like this
Entity
private int configid;
private String debtagerule;
private String remindebttype;
private int every;
private String unit;
private boolean selected;
//getters and setters
In addition to the above, this is the controller with which I am currently working
Controller
#GetMapping("/deleteConfigureCampaign")
public String deleteConfig(#ModelAttribute ConfigCampaign configCampaign, Model model) {
listConfigCampaigns.remove(configCampaign);
return "redirect:/configureCampaign";
}

In Spring Boot, You have to use JpaRepository<> for delete data from database and need to understand structure of Spring Boot project.
Here is sturcture of Spring Boot project:
Entity -> Repository -> Service -> Controller -> View.
Here down is code:
Entity
#Table(name = "config_master")
public class ConfigCampaign {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer configid;
private String debtagerule;
private String remindebttype;
private Integer every;
private String unit;
private boolean selected;
// Constructor, Getter and Setter
}
Repository
Use of #Modifying annotation: It is used to enhance the #Query annotation so that we can execute not only SELECT queries, but also INSERT, UPDATE, DELETE, and even DDL queries
#Repository
public interface ConfigRepo extends JpaRepository<ConfigCampaign, Integer>{
#Modifying
#Transactional
#Query(nativeQuery = true, value = "DELETE FROM config_master WHERE configid IN(?1)")
void delConfig(List<Integer> configId);
}
Service
#Service
public class PojoServiceImpl{
#Autowired
private ConfigRepo configRepo;
#Override
public void delConfig(Integer[] configId) {
configRepo.delConfig(Arrays.asList(configId));
}
}
Controller
// Show table of Config Campaign
#RequestMapping(value = "/showconfig", method = RequestMethod.GET)
public String getConfig(Model mdl)
{
List<ConfigCampaign> getConfig = pojoService.getAllConfig();
mdl.addAttribute("config", getConfig);
return "showConfigCampaign";
}
// Delete item from Config Campaign
#RequestMapping(value = "/delcampaign", method = RequestMethod.GET)
public String deleteConfig(#RequestParam("cid") Integer[] configId)
{
pojoService.delConfig(configId);
return "redirect:/showconfig";
}
showConfigCampaign
You have to add configData.configid in checkbox.
<form th:action="#{/delcampaign}" th:object="${sconfig}">
<div class="container">
<div class="row">
<div class="col-sm-12">
<table class="table" style="text-align: center">
<thead>
<tr>
<th scope="col">Remove</th>
<th scope="col">Debt Age Rule</th>
<th scope="col">Reminder</th>
<th scope="col">Frequency</th>
</tr>
</thead>
<tbody>
<tr th:each="configData: ${config}">
<td><input type="checkbox" name="cid" th:value="${configData.configid}"/></td>
<td th:text="${configData.debtagerule}"></td>
<td th:text="${configData.remindebttype}"></td>
<td th:text="${configData.every}"></td>
</tr>
</tbody>
</table>
<input type="submit" value="Delete Users" />

populating thymeleaf dropdown with data of another table

i'm new to spring-boot. In my system there are two models named subject,course(two databases with the same names and connected by the foreign key course_id).I need to make it possible to select course name in a dropdown list in the addSubject thymeleaf form. Can someone please tell me how to do this
Subject.DAO file
#Service
public class SubjectDAO {
#Autowired
SubjectRepository subjectRepository;
//to save a subject
public Subject save(Subject subject){
return subjectRepository.save(subject);
}

//get a subject by id

subjectRepository.deleteById(id);
}
}

public Course save(Course course){
return courseRepository.save(course);
}

So you want to load Course combo inside subject html
You need to modify subject controller
#RequestMapping("/subject")
public String viewHomePage(Model model){
List<Subject> subjectDetails= subjectDAO.findAll();
List<Course> courseDetail= courseDAO.findAll();
model.addAttribute("subjectDetails",subjectDetails);
model.addAttribute("courses",courseDetail);
return "subject";
}
In HTML
<tr>
<td>Course:</td>
<td>
<select th:field="*{course_code}">
<option value="">Choose..</option>
<option th:each="course: ${courses}" th:value="${course.id}" th:text="${course.name}" />
</select>
</td>
</tr>
<tr>
Edit 1:
I think you are loading addSubject.html
In that case you need to modify addSubject controller
#RequestMapping("/subject/new")
public String addSubject(Model model){
Subject subject =new Subject();
model.addAttribute("subject",subject);
List<Course> courseDetail= courseDAO.findAll();
model.addAttribute("courses",courseDetail);
return "addSubject";
}
Edit 2:
As per your code in Git I can see
#Autowired
private SubjectDAO subjectDAO;
private CourseDAO courseDAO;
It should be
#Autowired
private SubjectDAO subjectDAO;
#Autowired
private CourseDAO courseDAO;

First add all courses to the ModelMap
model.addAttribute("cources",courseDao.findAll());
Then use th:each attribute to populate select options
<select th:field="*{course}">
<option value="">Choose..</option>
<option th:each="c: ${cources}" th:value="${c.id}" th:text="${c.name}" />
</select>

Recover form in JAVA-Spring (with thymeleaf) from html page

I am new in development tool and i am trying to use spring with thymeleaf to create a form to register on a website. I am currently not able to recover information from the form to another page which only show the list of users.
I create a classic Spring boot security in Eclipse with model/service/dao/controller java files.
My Model java file --> Register.java
#Entity
public class Register {
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private long id;
private String pseudo;
private String lastname;
private String firstname;
private String sex;
private String country;
private String phone;
private String spokenlanguages;
private String email;
private String password;
private String job;
private boolean premium;
public void updateRegister(String pseudo, String lastname, String firstname, String sex, String country, String phone,
String spokenlanguages, String email, String password, String job, boolean premium) {
this.pseudo = pseudo;
this.lastname = lastname;
this.firstname = firstname;
this.sex = sex;
this.country = country;
this.phone = phone;
this.spokenlanguages = spokenlanguages;
this.email = email;
this.password = password;
this.job = job;
this.premium = premium;
// with all the getters & setters
}
My Service java file --> RegisterService.java
public interface RegisterService {
public List<Register> list();
public Register getById(long id);
}
My Repository Java file --> RegisterRepository.java
#Repository
public interface RegisterRepository extends PagingAndSortingRepository<Register, Long> {}
My Controller Java file --> RegisterController.java
#Controller
public class RegisterController {
#Autowired
RegisterRepository registerRepository;
#RequestMapping(value="/register", method=RequestMethod.GET)
public String form (Model model) {
return "register/form";
}
#PostMapping("/register/add")
public String registerAdd(
#Valid Register register,
BindingResult result,
Model model) {
if (result.hasErrors()) {
return "redirect:/error";
}
else {
Register r = new Register();
r.updateRegister(register.getPseudo(),
register.getLastname(),
register.getFirstname(),
register.getSex(),
register.getCountry(),
register.getPhone(),
register.getSpokenlanguages(),
register.getEmail(),
register.getPassword(),
register.getJob(),
register.isPremium());
System.out.println(r);
registerRepository.save(r);
model.addAttribute("registerlist", registerRepository.findAll());
return "register/valid";
}
}
#RequestMapping(value="/register/valid", method=RequestMethod.GET)
public String list (Model model) {
return "redirect:/home";
}
}

Thanks in advance for the help.
Feel free to ask me more in order to a better unterstanding...

Try to add #ModelAttribute("register") in your registerAdd method, so it should look like
#RequestMapping(value="/register/add", method=RequestMethod.POST)
public String registerAdd(#ModelAttribute("register") #Valid Register register, BindingResult result, Model model)
Let me know if it was the problem.
Edit1
Add this line to your GET mapping
model.addAttribute("register", new Register());
So it should look like:
#RequestMapping(value = "/register", method = RequestMethod.GET)
public String form(Model model) {
model.addAttribute("register", new Register());
return "register/form";
}
Hope it solves the problem :)

I have used html and thymeleaf here. This is my controller. In the controller I want to pass parameters to the sendUserRegisterEmail method which I was taken from the user.
#Autowired
private EmailService emailService;
#ResponseBody
#RequestMapping(value = "/contact-us", method = RequestMethod.POST)
public String showContactForm(#RequestParam("name") String contactName, #RequestParam("email") String contactEmail) {
emailService.sendUserRegisterEmail(contactName, contactEmail);
return "index";
}
I wrote a DTO class as well.
public class ContactUsDto {
private String name;
private String email;
private String telephone;
private String message;
public ContactUsDto(String name, String email, String telephone, String message) {
this.name = name;
this.email = email;
this.telephone = telephone;
this.message = message;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
}
Currently I get no errors. But the email is not receiving. I have no any issues with the method which I used to send the email. Because I have used it in another instances. The only issue is passing form data to it. Please help me to resolve this

#RequestParam is used to pass the request parameters e.g.
http://example.com/path?name=myName&email=myEmail
Whereas #RequestBody is used to get the request's body, which in most cases for REST is a json (application/json) body. So your method will be
#ResponseBody
#RequestMapping(value = "/contact-us", method = RequestMethod.POST)
public String showContactForm(#RequestBody ContactUsDto contactUsDto ) {
emailService.sendUserRegisterEmail(contactUsDto.getContactName(), contactUsDto.getContactEmail());
return "index";
}

add to your input attibute name like this
<input type="email" name="email" class="form-control" th:value="${email}" placeholder=""/>
<input name="name" type="text" th:value="${name}" placeholder=""/>
and try again .
