I have met the error when I am implementing a method in Netbeans.
java.lang.IllegalArgumentException: You have provided an instance of
an incorrect PK class for this find operation.
Class expected : class java.lang.Integer,
Class received : class java.lang.String.
Below are the entities that are used in the method:
public class Staff implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Basic(optional = false)
#Column(name = "STAFF_ID")
private Integer staffId;
#Size(max = 30)
#Column(name = "NAME")
private String name;
#Size(max = 100)
#Column(name = "PASSWORD")
private String password;
#Size(max = 20)
#Column(name = "ROLES")
private String roles;

public Staff() {

public Staff(Integer staffId) {
this.staffId = staffId;

}

}
#Override
public int hashCode() {
int hash = 0;

return hash;

public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Staff)) {
return false;
}

return false;
}
return true;
}
#Override
public String toString() {
return "entity.Staff[ staffId=" + staffId + " ]";
}
}
The method in my controller:
public String verify(){
String result = "failed";
String authcode = staffBean.getVerifyCodeByName(getLoginUserName());
//get verifycodefrom database by name
Staff temp = staffBean.find(authcode);
if ( code.equals(authcode)){
result ="success";
temp.setVerifyCode("");
temp.setVerifyStatus("Verified");
staffBean.edit(temp);
}
return result;
My facade:
#Override
public String getVerifyCodeByName(String name) {
Query q = em.createNamedQuery("Staff.getVerifyCodeByName");
q.setParameter("name", name);
return ((String) q.getSingleResult()).toString();
My facadelocal:
public String getVerifyCodeByName(String name);
i am unsure which variable has the error in it. :(
i guess the Problem comes on the line:
Staff temp = staffBean.find(authcode);
You try to search for a Staff instance, based on a string. But the search you would like to do should be based on an Integer, as this is your #Id attribute.
What is the primary key of your Staff object? You don't show us the whole class. The error message is saying that you are expected to pass an Integer and you are passing a String.

I'm using spring boot to construct a database using AWS RDS as well. I want to track down how many stars a user gives to different products. I learnt to go around the many-to-many relationship by creating a table connecting two one-to-many other tables. For this reason, I have created the following tables:
When a user rates a product, an api is called through the put command in order to track down which user(uid) rates which product(pid). When the product(pid) is not rated by anyone, a rate_item is created that contains the pid and also the uid. However, when another user (with a different uid) rates the same product (same pid), the rate_item is updated, which is a problem becausse supposedly, a new row containing the same pid and a different uid should be created, as seen in the following (user with "uid 1" has already rated the same product and when user with "uid 2" rates the same product, the entity gets updated, but not like a new entity is created):

I will really appreciate anyone who can help me with this! I've been stuck for a whole day! I don't want to use the many-to-many annotation because it seems a bit messy. Thanks!
I have found the mistake. In my RatingEntity code, the getter and setter are erroneous. There's some typos there. It should be
public Integer getPruid() {
return pruid;
}
public void setPruid(Integer pruid) {
this.pruid = pruid;
}
I have a problem when using Long type attributes, I created an attribute called 'Cnh' which receives a 11 digit code, I already put the L in the end of the value, but when I run it in JUnit it still says Integer number too large: 06161567318l.
Is there any possible way I can avoid it
I don't wanna change the attribute type, because I have another which has the same problem but it is a 'hashcode' (it would be really tough to change)

I need it to accept values way bigger than the limit(I know... but I also know you know what I'm talking about) ]:)
I'm running a query via Hibernate and it´s returning a list. But the list contains objects instead of my Entities... I'm not a pro in Hibernate, but my other queries work well. I have got no idea what is my mistake right now.

List users = null;
try {
startOperation(false);
Query query = getSession().createQuery(" from UserEntity where mandant = '" + id + "'");
users = query.list();

handleException(e);

Any ideas what im doing wrong?
I hope I understood the question correctly and that my answer will help you.
Please use query.setParameter([name of parameter], [value]) it will help you with the concationation. more details on that link: https://www.mkyong.com/hibernate/hibernate-parameter-binding-examples/
Your Entitys are now Objects in the users List. you can define your List already to the Objecttype of your desire, for example List<UserEntity> users = q.getResultList()
2.a now you can adress the single elements in your list like
if(!users.isEmpty()) {
for(UserEntity uEntity : users){
uEntity.doSomething()
}
return users.get(0)}
I hope this was helpful for you
this is my first post, so please bear with me if i do make any errors.
I get an error " java.lang.IllegalStateException: During synchronization a new object was found through a relationship that was not marked cascade PERSIST"
whenever i want to query(add,edit,delete) the database.
The tables related are sponsors and donations. There is a one to many relationship between them. Classes below:

The field
#ManyToOne(optional = false)
private Sponsors sponsorid;
in the Donations entity is not configured for cascading. Try changing it to:
#ManuToOne(optional = false, cascade = CascadeType.ALL)
private Sponsors sponsorid;
I feel my app runs slow. I use Java for my server, so except java itself,the first reason of slow run, I think, is the account of database access. Hibernate could search all attribute associate with the entity which you are using, so I think it may send a lot of SQL language when finding one entity. If there's a large concurrent happening ,the trouble will happen.

Just like this, User contains Topic, Label or other Entity in future. So I think that is not possible to remove this association. How could I improve my database access to improve access speed?
Another reason influncing the app speed may be my algorithm. I use bubble sort, selection sort, and quick sort. Each sort seems to cost little time on little data. But what if the concurrent occurs? 300 users may cost only 20 msec but 300 000 I couldn't imagine.
Here is my sort code:
private static List<Map<String,Object>> sortInteger(List<Map<String,Object>> list){
int index = 0;
int max = 0;
Map<String,Object> temp = new HashMap<String, Object>();
for(int i=0;i<list.size();i++){
for(int j=0;j<list.size()-i-1;j++){
Map<String,Object> pre = (Map<String, Object>) list.get(j);
Map<String,Object> next = (Map<String, Object>) list.get(j+1);
if((Integer)pre.get("sortnum")<(Integer)next.get("sortnum")){
temp = pre;
list.set(j, next);
list.set(j+1,pre);
}
}
}
return list;
}
So in terms of above, I need some suggestion to solve my question,either theory or code.
