This api works for inserting and updating but everytim I update the image dissapears so I am trying to say orElse if image not exist set image to existing image any advice pls

image.ifPresent(pic ->
{
try {
bank.setImage(new Binary(BsonBinarySubType.BINARY, pic.getBytes()));
} catch (IOException e) {
e.printStackTrace();
}
});
Bank result = bankRepository.save(bank);
return ResponseEntity.ok().body(result);

Use Something like this

public ResponseEntity<Entity> updateEntity(#RequestPart("entity") #Valid Entity entity, #RequestPart("file") #Valid Optional<MultipartFile> image) throws IOException {

I have a application written in Spring, Hibernate and SpringBoot,
I have 2 entities class with one to many mapping,
Here are my LeadUserDb entity class
#Entity
#Table(name="lead_user_db")
#NamedQuery(name="LeadUserDb.findAll", query="SELECT l FROM LeadUserDb l")
public class LeadUserDb implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
private Integer id;
#Column(name="branchcode")
private String branchcode;
#Column(name="reporting_level")
private int reportingLevel;
//bi-directional many-to-one association to UserBasicDetailsDb
#ManyToOne
#JoinColumn(name="email_Id")
private UserBasicDetailsDb userBasicDetailsDb;
public LeadUserDb() {
}
public String getBranchcode() {
return this.branchcode;
}
public void setBranchcode(String branchcode) {
this.branchcode = branchcode;
}
public int getReportingLevel() {
return this.reportingLevel;
}
public void setReportingLevel(int reportingLevel) {
this.reportingLevel = reportingLevel;
}
public UserBasicDetailsDb getUserBasicDetailsDb() {
return this.userBasicDetailsDb;
}
public void setUserBasicDetailsDb(UserBasicDetailsDb userBasicDetailsDb) {
this.userBasicDetailsDb = userBasicDetailsDb;
}
And This is my UserBasicDetailsDb Entity Class
#Entity
#Table(name="user_basic_details_db")
public class UserBasicDetailsDb implements Serializable {
private static final long serialVersionUID = 1L;
#Id
private String email;
private String address;

this.email = email;
}
public String getAddress() {
return this.address;
}
public void setAddress(String address) {
this.address = address;
}
public String getCity() {
return this.city;
}
public void setCity(String city) {
this.city = city;
}
public String getDob() {
return this.dob;
}
public void setDob(String dob) {
this.dob = dob;
}
public String getMobile() {
return this.mobile;
}
public void setMobile(String mobile) {
this.mobile = mobile;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
public String getPan() {
return this.pan;
}
public void setPan(String pan) {
this.pan = pan;
}
public String getPincode() {
return this.pincode;
}
public void setPincode(String pincode) {
this.pincode = pincode;
}
public String getState() {
return this.state;
}
public void setState(String state) {

}
public List<LeadUserDb> getLeadUserDbs() {
return this.leadUserDbs;
}
public void setLeadUserDbs(List<LeadUserDb> leadUserDbs) {
this.leadUserDbs = leadUserDbs;
}
public LeadUserDb addLeadUserDb(LeadUserDb leadUserDb) {
getLeadUserDbs().add(leadUserDb);
leadUserDb.setUserBasicDetailsDb(this);
return leadUserDb;
}
public LeadUserDb removeLeadUserDb(LeadUserDb leadUserDb) {
getLeadUserDbs().remove(leadUserDb);
leadUserDb.setUserBasicDetailsDb(null);
return leadUserDb;
}
what i want to achieve is to create a query like this one
SELECT a.branchcode as branchCode,b.name FROM lead_user_db a
inner join user_basic_details_db b
where b.email = a.email_id and a.reporting_level = 3
here is what I have written my Repository class
public interface GetUserList extends CrudRepository<LeadUserDb, Integer> {
#Query(value = "SELECT a.id, a.branchcode as branchCode,b.name as name,a.reporting_level,a.email_id FROM lead_user_db a\n" +
"inner join user_basic_details_db b\n" +
"where b.email = a.email_id and a.reporting_level = ?1", nativeQuery = true)
List<LeadUserDb> findByReportingLevel(int reportingLevel);
}
and this is how I am calling it
UserBasicDetailsDb details = GetUserList.findByReportingLevel(3);
NOTE
Getting a new error Cannot determine value type from string test#dev.com
I am getting a hell lot of data, and the actual output have only 2 records
My question is how can i fetch the list of user based on reportingLevel
Any help would be appreciated

In debug mode, string response in objectMapper shows correct response, string response in attractionMainResponse giving a success but can't map the attractionDetailModel, giving null.
Is this about a Jackson ObjectMapper? Is it possible to create a smaller example, that makes it easier to give a solution.
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.
I have used objectify to query the GAE datastore i have set up that has at least one entity in it but i keep getting the following response
200 OK
Show headers -
{
"kind": "call#resourcesItem",
"etag": "\"AiR-q6YO1YYMgAaz-ZfT_fl7oeY/pcKQAVaDylr_ZSckRfQAxsphOUU\""
}
here is what the objectify request looks like
#ApiMethod(name = "queryCalls", path = "queryCalls", httpMethod = HttpMethod.POST)
public List<Call> queryCalls()
{
Query<Call> query = ofy().load().type(Call.class).order("name");
return query.list();
}
Call is obviously the class of the entity that is being used.
Any solutions would be most appreciated

As you have highlighted in your last comment, your #Entity classes must have a no-arg constructor in order for Objectify to be able to construct objects from Datastore entities.
Once that is sorted you will be able to order your results using #Indexed properties defined in your class.

public int getQuantity() {
return quantity;

my script updateProduct
public boolean updateProduct(Product p) {
boolean ret = false;
if (productDao != null) {
try {
productDao = getDao(Product.class);
UpdateBuilder<Product, Integer> updateBuilder = productDao
.updateBuilder();
updateBuilder.updateColumnValue("name", p.getName());
updateBuilder.updateColumnValue("quantity", p.getQuantity());
updateBuilder.updateColumnValue("categorie", p.getCategorie());
updateBuilder.updateColumnValue("description", p.getDesc());
updateBuilder.updateColumnValue("photo", p.getPhoto());
// but only update the rows where the description is some value
updateBuilder.where().eq("productId", p.getProductId());
// actually perform the update
String str = updateBuilder.prepareStatementString();
// UPDATE `Product` SET `name` = 'gcd' ,`quantity` = 1
// ,`categorie` = 1 ,`description` = ? ,`photo` = '' WHERE
// `productId` = 0
if (productDao.update(updateBuilder.prepare()) != 1) {
ret = false;
} else {
productDao.refresh(p);
ret = true;
}
} catch (Exception e) {
ret = false;
e.printStackTrace();
}
}
return ret;
}
then I call it with a function like this, but allways return false :(
public boolean updateProduct(Product p) {
boolean ret = false;
try {
ret = getHelper().updateProduct(p);
} catch (Exception e) {
e.printStackTrace();
ret =false;
}
return ret;
}
I can create and delete but I can not update . I tried everything.
If you please take a moment to answer my question I will appreciate.
for other developers, if you come face to face with a problem like this you should ensure the table must have an identity key.
#DatabaseTable(tableName = "User")
public class User {
#DatabaseField(generatedId = true)
public int id;
#DatabaseField
public String ServiceUserId;
#DatabaseField
public boolean IsActive;
#DatabaseField
public String FirstName;
#DatabaseField
public String LastName;
#DatabaseField
public String Key;
#DatabaseField
public String Email;
}
The solution was
Simply get the Instance of the object Product from the DB then modify to finaly send to the updateProduct method.
for example first I need to create any method first to get an objet by ID
// get the Instance calling to the getProductByID
Product p = getHelper().getProductByID(p.getId())
//modify any value of the product
p.setFirstName("asd");
//call the update
ret = getHelper().updateProduct(p);
then my objects is Updated.
Put attention for the object Id(should be the same) and use the natif function update(Product);
In your case, you must override equals and hashCode.
