java.lang.ClassCastException: java.lang.String cannot be cast to [C

I'm using the following code to convert char[] to string, but it is throwing:
java.lang.ClassCastException: java.lang.String cannot be cast to [C
char[] charArray = user.getUserPassword();
String userPassword = String.valueOf(charArray);
Here user.getUserPassword() returns char[]. I also tried the following:
String userPassword = new String(charArray);
But it also throws the same exception. (I'm using java 8.)
The complete stack trace;

This is the UserDAOImpl class;
#Repository("userDAO")
public class UserDAOImpl implements UserDAO{
#Autowired
private SessionFactory sessionFactory;
#SuppressWarnings("unchecked")
#Override
public List<Object[]> login(String UserName, String UserPassword) {
Session session = sessionFactory.openSession();
String hql = HqlConstant.UserQuery;
Query query = session.createQuery(hql);
query.setParameter("UserName", UserName);
query.setParameter("UserPassword", UserPassword);
List<Object[]> list = query.list();
session.close();
return list;
}
}
This is the HQL query;
from UserModel um inner join um.userRoleModel where um.UserName = :UserName and um.UserPassword = :UserPassword

My theory on what happens:
You put a String into
query.setParameter("UserPassword", UserPassword);
BUT
As you said, your userPassword property for your user Object is of type char[]
Now hibernate is a quite clever tool - it would recognize that object type for userPassword is char[] and then tries to set that into the generated query. But you passed a String.
Try this for once:
query.setParameter("UserPassword", UserPassword.toCharArray());
in your login method.

Try use
String userPassword = new StringBuilder()
.append(user.getUserPassword()).toString();

Try this:
String result=String.copyValueOf(charArray);

If you want to cast a String to a char (array, I'm guessing). I used a for loop.
for (int i = 0; i < length; i++) {
char[i] Letter = message1.charAt(i);
}
This was derived from my older code, but this should still convert the string message1 to a char Array... Tell me if this would help :P

I was facing the similar issue:
java.lang.ClassCastException: java.lang.String cannot be cast to [C
in the line
commons.validateException(String.valueOf(response.getBody().path("code")),
String.valueOf(response.getBody().path("message"))
Adding .toString() resolved the issue. Below is the line of code.
commons.validateException(String.valueOf(response.getBody().path("code").toString()),
String.valueOf(response.getBody().path("message").toString())

Hibernate: How to delete a batch of object from subclass table when inheritanceType.joined is set?

I have two classes. One is Question, one is TempQuestion:
#Entity
#Table(name="tbQuestion")
#DiscriminatorColumn(
name="discriminator",
discriminatorType=DiscriminatorType.STRING)
#Inheritance(strategy=InheritanceType.JOINED)
public abstract class Question {
private Integer qstId;
private String qstNum;
private Integer versionNum;
private String qstTitle;
private String qstInstruction;
private InterviewQstType qstType;
private boolean isChildQuestion;
private AnswerDataType answerDataType;
private String chartNodeLocation;
private Question parentQst;
private Set<Question> childQsts;
private Set<QstOption> options;
private Set<Answer> answers;
private List<QstOption> jumpTrgs;
.....
}
#Entity
#Table(name="tb_temp_question")
#DiscriminatorValue("temporary")
#PrimaryKeyJoinColumn(name="qstId")
#OnDelete(action = OnDeleteAction.CASCADE)
public class TempQuestion extends Question{
}
There is no any field only in TempQuestion (Just for testing purpose).
When I insert several records of data into these two tables, it works fine.
But When I try to delete all of them with the coding below, it gives me an error.
#Autowired
private SessionFactory sessionFactory;
public void deleteAll{
Session session = sessionFactory.openSession();
String stringQuery = "DELETE FROM TempQuestion";
Query query = session.createQuery(stringQuery);
query.executeUpdate();
}

And When I am calling the api I am getting response like
{
"timestamp": 1431668344518,
"status": 500,
"error": "Internal Server Error",
"exception": "org.springframework.transaction.CannotCreateTransactionException",
"message": "Could not open JPA EntityManager for transaction; nested exception is javax.persistence.PersistenceException: org.hibernate.TransactionException: JDBC begin transaction failed: ",
"path": "/api/act"
}
Here is my application.property
# DataSource settings: set here configurations for the database connection
spring.datasource.url = jdbc:mysql://localhost:3306/api
spring.datasource.username = root
spring.datasource.password = root
spring.datasource.driverClassName = com.mysql.jdbc.Driver
# Specify the DBMS
spring.jpa.database = MYSQL
# Show or not log for each sql query
spring.jpa.show-sql = true
# Hibernate settings are prefixed with spring.jpa.hibernate.*
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.naming_strategy = org.hibernate.cfg.ImprovedNamingStrategy
Here is my application class
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Bean
public Application webSecurityConfigurerAdapter() {
return new Application();
}
#Bean
public Filter characterEncodingFilter() {
CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
characterEncodingFilter.setEncoding("UTF-8");
characterEncodingFilter.setForceEncoding(true);
return characterEncodingFilter;
}
}
Edit:
Here is my controller code
#RequestMapping(value = "/", method = RequestMethod.POST)
#ResponseBody
public String createUser( #RequestBody User user){
userDao.save(user);
return ("Done");
}
}
Here is my Dao
#Transactional
public interface UserDao extends CrudRepository<User, Long> {
}
Can anyone tell me what is the actual problem and how to solve this?If more information needed feel free to ask.

I suggest you to add this config to your application.properties add retest :
spring.datasource.validationQuery=SELECT 1
spring.datasource.testOnBorrow=true

... 56 more
an this is the method that i want to handle the exception it returns an ArrayList :
public List<Tache> listPhaseTaches(Integer idphaseKey) {
return new java.util.ArrayList<Tache>(phaseDAO.findPhaseByPrimaryKey(idphaseKey).getTaches());
}
The problem is I don't know what i should do for handling NullPointerException for a method that returns an Arraylist

List list = someMethod();
if(list!=null){
//your logic
}
else{
return new List<T>();
}
Make sure that you return not-null value

you can handle this like
List list = someMethod();
if(list!=null){
//your logic
}
else{
}

your error lies either at phaseDAO is null or phaseDAO.findPhaseByPrimaryKey(idphaseKey) this returns null OR phaseDAO.findPhaseByPrimaryKey(idphaseKey).getTaches() this returns null
Use this >>
public List<Tache> listPhaseTaches(Integer idphaseKey) {
if(phaseDAO!=null){
if(phaseDAO.findPhaseByPrimaryKey(idphaseKey)!=null){
if(phaseDAO.findPhaseByPrimaryKey(idphaseKey)!=null){
return new ArrayList(phaseDAO.findPhaseByPrimaryKey(idphaseKey));
}
}
}
return null;
}

Provide the following null checks:
phaseDAO != null
phaseDAO.findPhaseByPrimaryKey(idphaseKey) != null
phaseDAO.findPhaseByPrimaryKey(idphaseKey).getTaches() != null

Try to put the SQL keyword AS between your column name and the aliases like this:
String query =
"SELECT cus.id, pLead.id AS leadId, cus.code AS custCode, cus.primaryName AS custName, " +
"cus.primaryKhmerName AS custkhmerName, pLead.phoneNo, prot.englishName AS propertyType, " +
"pro.houseno AS houseNo, pro.streetno AS streetNo, pLead.address " +
"FROM Customer cus, Contract con, Property pro, PropertyType prot, Lead pLead " +
"WHERE cus.id = con.customer AND prot.id = pro.propertyType AND pro.id = con.property AND cus.primaryLead = pLead.id ";
It is always a good practice to use the AS keyword because it is the SQL-92 standard.
