I have a field in the Firestore database that is TimeStamp and is in this format: Quarta-feira, 11 de Outubro de 2017 às 10:24:54 GMT-03:00
It is defined as: map.put("timestamp", FieldValue.serverTimestamp());
According to Firestore instructions, you need to add a annotation, directly to the model class.
I have in my class the TimeStamp field in String. I tried using TimeStamp and it does not work
What is the best way to solve this problem?
Code Class Model:
public class Servicos {
private String nome_produto;
private String duracao;
private String valor;
private String valor_old;
private String categoria;

private String sub_categoria_nome;
private String descricao;
private String duracao_milis;
private String timestamp;
public Servicos() {
}
public Servicos(String nome_produto, String duracao, String valor, String valor_old,
String categoria, String categoria_nome, String sub_categoria, String sub_categoria_nome,
String descricao, String duracao_milis, String timestamp){
this.nome_produto = nome_produto;
this.duracao = duracao;
this.valor = valor;
this.valor_old = valor_old;
this.categoria = categoria;
this.categoria_nome = categoria_nome;
this.duracao_milis = duracao_milis;
this.sub_categoria = sub_categoria;
this.sub_categoria_nome = sub_categoria_nome;
this.descricao = descricao;
this.timestamp = timestamp;
}
public String getNome_produto() {

Ref Firestore Documentation: Link Firestore
// If you're using custom Java objects in Android, add an #ServerTimestamp
// annotation to a Date field for your custom object classes. This indicates
// that the Date field should be treated as a server timestamp by the object mapper.
DocumentReference docRef = db.collection("objects").document("some-id");
// Update the timestamp field with the value from the server
Map<String,Object> updates = new HashMap<>();
updates.put("timestamp", FieldValue.serverTimestamp());
docRef.update(updates).addOnCompleteListener(new OnCompleteListener<Void>() {
// ...
// ...
Here's an example of how to use ServerTimestamp with a custom Java class:
public class Rating {
private String userId;
private #ServerTimestamp Date timestamp;
public Rating() {}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public Date getTimestamp() {
return timestamp;
}
public void setTimestamp(Date timestamp) {
this.timestamp = timestamp;
}
}
Try this:
public class Klass {
private Date timestamp;
public Klass() {}
#ServerTimestamp
public Date getTimestamp() {
return timestamp;
}
public void setTimestamp(Date timestamp) {
this.timestamp = timestamp;
}
}

I have a payload string and want to change it to values of entity. The payload as below:
{"resultCode":"200","resultMessage":"Success","consent":[{"name":"A","sourceSystem":"IGN","updateBy":"Admin","remark":"good","version":"1.0","updateDate":1600658621871},{"name":"B","sourceSystem":"IGN","updateBy":"Admin","remark":"good","version":"2.0","updateDate":1874819158457},{"name":"C","sourceSystem":"IGN","updateBy":"Admin","remark":"good","version":"3.0","updateDate":1358819159457}]}
And the entities:
public class ListConsentResponse {
private String resultCode;
private String resultMessage;
private List<ConsentDTO> consent;
public String getResultCode() {
return resultCode;
}
public void setResultCode(String resultCode) {
this.resultCode = resultCode;
}
public String getResultMessage() {
return resultMessage;
}
public void setResultMessage(String resultMessage) {
this.resultMessage = resultMessage;
}
public List<ConsentDTO> getConsent() {
return consent;
}
public void setConsent(List<ConsentDTO> consent) {
this.consent = consent;
}
}
public class ConsentDTO {
private String name;
private String sourceSystem;
private String updateBy;
private String remark;
private String version;
private Timestamp updateDate;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSourceSystem() {
return sourceSystem;
}
public void setSourceSystem(String sourceSystem) {
this.sourceSystem = sourceSystem;
}
public String getUpdateBy() {
return updateBy;
}
public void setUpdateBy(String updateBy) {
this.updateBy = updateBy;
}
public String getRemark() {
return remark;
}
public void setRemark(String remark) {
this.remark = remark;
}
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
public Timestamp getUpdateDate() {
return updateDate;
}
public void setUpdateDate(Timestamp updateDate) {
this.updateDate = updateDate;
}
}
But when I parse to json using GsonBuilder :
ListConsentResponse listConsentResponse = Utility.createGsonObject()
.fromJson(payload, ListConsentResponse.class);
I have error:
com.google.gson.JsonSyntaxException: 1600658621871
Is there any way help me get parse the string with Timestamp value to entity. Or at least can I change the Timestamp value to String value in payload (For example change 1600658621871 to "1600658621871").
Thanks.
I'm doing the below query to find records that are in a temp table and dont exist in master then insert the results to the master table
#Query(value = "select b from InboundTemp b where b.transactionId NOT IN (SELECT p2.transactionId FROM Inbound p2)")
ArrayList<InboundTemp> findMissing();
However if I pass a single result object to the JpaRepository save method (To update the master table)it does an update instead of an insert.
what would I be doing wrong?

The only reason why JPA does an update instead of insert is that the Primary Key already exists in your persistence layer or your table. So kindly check or post your source code in order to review it and find what is wrong (if the issue is not in your data).
Now that you have updated the question with the source code, your bug is probably on the instantiation of the postpaytransaction object.
try to insert into your loop before everything else
postpaytransaction = new PostPayTransaction ()
I had the exactly same issue. My point was that the SpringBoot was automatically recreating the DB on startup, incorrectly creating the identity column in the table.
Look for spring.jpa.hibernate.ddl-auto.
I need to map two pojo class using one to many, but getting the below error
com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column 'testCaseStepsform' at row 1

You should choose to annotate object properties or getters. Don't use it simultaneously.
Apart, #xl0e answer
You need to correct mapping
#OneToMany(mappedBy = "testCaseForm", cascade = CascadeType.ALL)
public ArrayList<TestCaseStepsForm> getTestCaseStepsform() {
return testCaseStepsform;
}
I'm having a problem fetching data from database.
I'm trying to fetch the list of array.
But my problem is that i can only get the last element of the array maybe because it overwrites the previous one.
Here's my code.
String sql;
sql = "select * from NM_PROPERTIES_LOADER";
ResultSet rs = stmt.executeQuery(sql);
String prop_name = null;
String prop_value = null;
PropertyData reader = new PropertyData();
while(rs.next()){
prop_name = rs.getString("prop_name");
prop_value = rs.getString("prop_value");
reader.setPropName(prop_name);
reader.setPropValue(prop_value);
..//other setter..
System.out.println(prop_name + " " + prop_value);
}
prop.add(reader);
In my sysout I can retrieve all the datas. but on my page only the last element is retrieved. Here's my dao class.
public class PropertyData {
private int id;
private String propName;
private String propValue;
private String engineName;
private String desc;
private Date createdAt;
private String createdBy;
private Date updatedAt;
private String updatedBy;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getPropName() {
return propName;
}
public void setPropName(String propName) {
this.propName = propName;
}
public String getPropValue() {
return propValue;
}
public void setPropValue(String propValue) {
this.propValue = propValue;
}
public String getEngineName() {
return engineName;
}
public void setEngineName(String engineName) {
this.engineName = engineName;
}
public String getDesc() {
return desc;
}
public void setDesc(String desc) {
this.desc = desc;
}
public Date getCreatedAt() {
return createdAt;
}
public void setCreatedAt(Date createdAt) {
this.createdAt = createdAt;
}
public String getCreatedBy() {
return createdBy;
}
public void setCreatedBy(String createdBy) {
this.createdBy = createdBy;
}
public Date getUpdatedAt() {
return updatedAt;
}
public void setUpdatedAt(Date updatedAt) {
this.updatedAt = updatedAt;
}
public String getUpdatedBy() {
return updatedBy;
}
public void setUpdatedBy(String updatedBy) {
this.updatedBy = updatedBy;
}
}
In every iteration of the loop, you overwrite the content of reader.
You want to create reader inside the loop, not outside,
and also do prop.add(reader) inside the loop, not outside.
Like this:
String sql = "select * from NM_PROPERTIES_LOADER";
ResultSet rs = stmt.executeQuery(sql);
while(rs.next()) {
PropertyData reader = new PropertyData();
String name = rs.getString("prop_name");
String value = rs.getString("prop_value");
reader.setPropName(name);
reader.setPropValue(value);
// other setter calls..
prop.add(reader);
}
I have two classes which implement Parcelable. And objects of one of them I have to write to a list. First model:

public Date getUpdateTime() {

}
public void setUpdateTime(Date updateTime) {

}
public ChallengeCategory getCategory() {

}
public void setCategory(ChallengeCategory category) {

}
And I have a problem at this line: userArrayList = in.readTypedList(userArrayList, User.CREATOR); It looks like this: And example of the second model:
public class User implements Parcelable {

Can you help me to find my mistake?
You must initialized userArrayList before use it:
userArrayList = new ArrayList<User>();
in.readTypedList(userArrayList, User.CREATOR);
Initialize ArraList and retrieve the data to this list from parcelable.
Something like this:
userArrayList = new ArrayList<User>();
in.readTypedList(userArrayList, User.CREATOR);
