In Spring Tool Suite - The web application [ROOT] appears to have started a thread named [HikariPool-1 housekeeper] but has failed to stop it

I created a small application in Spring Tool suite 4. I checked my code hundreds of times but didn't find any error. When application is executed it says:
"The web application [ROOT] appears to have started a thread named [HikariPool-1 housekeeper] but has failed to stop it. This is very likely to create a memory leak."

JPA, Using CriteriaBuilder for filter query

I want to implement an additive filter on a table of records (Student information). This is the breakdown of the problem
There are three parameters to filter with.
The method returns count, the result, the pageSize and pageNumber.
The table changes with change in the filter parameter.
I am new to criteriaBuilder in JPA. Have managed to write some codes with some information i read online about it. I hope someone help me with it.
The kind of search was implemented on this site : www.hdpopcorns.co
This is my code;
public Page<Student> findStudentByParam(FindStudentDTO findStudentDTO, Pageable pageable) {
String studentName = findStudentDTO.getStudentName();
Long levelId = findStudentDTO.getLevel();
Long sclassId = findStudentDTO.getSclass();
CriteriaBuilder cb = emf.getCriteriaBuilder();
CriteriaQuery<FindStudentDTO> studentQuery = cb.createQuery(FindStudentDTO.class);
Root<Student> studentRoot = studentQuery.from(Student.class);
Root<SClass> classRoot = studentQuery.from(SClass.class);
List<Predicate> filterPredicates = new ArrayList<>();
if((studentName != null && !studentName.isEmpty()) && ((levelId == null) && (sclassId == null))){
System.out.println("Ths is level 1");
filterPredicates.add(
cb.or(
cb.like(cb.lower(studentRoot.get("firstName")),"%" + studentName + "%"),
cb.like(cb.lower(studentRoot.get("middleName")),"%" + studentName + "%"),
cb.like(cb.lower(studentRoot.get("lastName")),"%" + studentName + "%")
)
);
}else if(levelId != null && ((studentName == null && studentName.isEmpty()) && sclassId == null)) {
filterPredicates.add(cb.equal(studentRoot.join("level").get("id"),findStudentDTO.getLevel()));
log.info("I am here");
}else if(sclassId != null && ((studentName == null && studentName.isEmpty()) && levelId == null)) {
System.out.println("2");
filterPredicates.add(cb.equal(studentRoot.join("sClass").get("id"),findStudentDTO.getSclass()));

Thanks in advance

Ensure that the Student, Level and SClass entities are joined by the right #OneToMany/#ManyToMany annotations.
Since you are using JPA, I would suggest you take a look at QueryDSL to generate dynamic query predicates. You will need to first generate the Predicate classes for your entities. Once generated, these classes provide a great way of chaining predicates in a builder pattern.
There are very useful quick-start articles that you can find here and here.
HTH!

JSON parse error: Cannot construct instance of `com.example.greetapp.domain.User`

I'm using JHipster and I'm running the following curl command:

In my humble opinion, there are a couple of things to check.
First, it isn't recommended to use the same object to store data in your database and response a request. The data object could be GangUser, User and Gang, while the response objects GangUserApi, UserApi, and GangApi. With this approach, you'll be able to amend a layer without modifying another.
Second, your service is expecting a GangUser with a User inside. The same User Object that you use to store it in the database. You're just sending a String ("1") instead of an object there.
A quick solution could be modifying the JSON:
{
"role": "member",
"gang": "3",
"user": {
"id":"1"
}
}
But I would like to know if you understand what was going on. That is more important than just give you a quick solution.
Cheers.

Using Hibernate merge() and refresh()

I have a table, and I want to change state field of mapped table from 1 to 0 when I press delete button. Here is the logic.
It is my mapped table
#Entity
#Table(name = "POSITION_ACCOUNT")
public class PositionAccount {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Basic(optional = false)
#Column(name = "ID", columnDefinition = "NUMERIC(15, 0)",unique = true,nullable = false)
private Long id;
public Long getId() {
return id;
}
#Column(name = "ACCT_NUMBER")
private String accountNumber;
public String getAccountNumber() { return accountNumber; }
#Column(name = "ACCT_NAME")
private String accountName;
public String getAccountName() {
return accountName;
}
#Column(name = "CURRENCY_CODE")
private String currencyCode;
public String getCurrencyCode() {
return currencyCode;
}
#Column(name = "BALANCE")
private BigDecimal balance = new BigDecimal("0");
public BigDecimal getBalance() {
return balance;
}
#Column(name = "ACCT_TYPE")
private String accountType;
public String getAccountType() { return accountType; }
#Column(name = "STATE")
private int state = 1;
public int getState() {
return state;
}
public void setId(Long id) {
this.id = id;
}
public void setAccountNumber(String accountNumber) {
this.accountNumber = accountNumber;
}
public void setAccountName(String accountName) {
this.accountName = accountName;
}
public void setCurrencyCode(String currencyCode) {
this.currencyCode = currencyCode;
}
public void setBalance(BigDecimal balance) {
this.balance = balance;
}
public void setState(int state) {
this.state = state;
}
public void setAccountType(String accountType) { this.accountType = accountType; }
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
PositionAccount that = (PositionAccount) o;
return !(id != null ? !id.equals(that.id) : that.id != null);
}
#Override
public int hashCode() {
return id != null ? id.hashCode() : 0;
}
#Override
public String toString() {
return "PositionAccount{" +
"id=" + id +
", accountNumber='" + accountNumber + '\'' +
", accountName='" + accountName + '\'' +
", currencyCode='" + currencyCode + '\'' +
", balance=" + balance +
", state=" + state +
'}';
}
}
Here is my #ActionMethod
#Inject
private LoroNostroService service;
#Inject
private LoroNostroModel model;
#ActionMethod(ACTION_DELETE_ACCOUNT)
public void deleteAccount() {
PositionAccount account = tv_loro_nostro_accounts.getSelectionModel().getSelectedItem();
DeleteAccount input = new DeleteAccount();
input.setAccountId(account.getId());
input.setType(account.getAccountType());
input.setAccNum(account.getAccountNumber());
input.setAccName(account.getAccountName());
input.setCurrency(account.getCurrencyCode());
input.setBalance(account.getBalance());
input.setCurState(0);
service.deleteAccount(input, context.getTaskView(), result -> {
model.getAccounts().addAll(result.getAccount());
tv_loro_nostro_accounts.getSelectionModel().selectFirst();
});
}
where tv_loro_nostro_accounts is TableView from which I make a selection. DeleteAccount class is a class where I define all fields of my table with getters and setters. service.deleteAccount after some manipulations goes here:
#Path("deleteAccount")
#POST
public DeleteAccount deleteAccount(DeleteAccount model){
try {
model = operationService.execute(model,(result, userDetails) -> {
PositionAccount a = new PositionAccount();
a.setAccountType(result.getType());
a.setAccountNumber(result.getAccNum());
a.setAccountName(result.getAccName());
a.setCurrencyCode(result.getCurrency());
a.setState(0);
service.deleteAccount(a);
result.setState(OperationState.DONE);
return result;
});
}catch (AdcException e) {
logger.error("X: ", e);
model.setState(OperationState.ERROR);
model.setErrorText(e.getLocalizedMessage(model.getLocale()));
} catch (Exception e) {
logger.error("X: ", e);
model.setState(OperationState.ERROR);
model.setErrorText(e.getLocalizedMessage());
}
return model;
}
where service.deleteAccount is
public void deleteAccount(PositionAccount account){
repository.deleteAccount(account);
}
and repository.deleteAccount is
public void deleteAccount(PositionAccount account){
em.merge(account);
em.refresh(account);
}
When I run above, I receive error
Entity not managed; nested exception is java.lang.IllaegalArgumentException: Entity not managed
Please hrlp to fix above.

merge returnes the managed entity instance, so to make this not to throw exception do:
account = em.merge(account);
em.refresh(account);
However, refresh will overwrite all the changes, so it is not needed here. Your method should look like:
public void deleteAccount(PositionAccount account) {
em.merge(account);
}
