I'm trying to use Hibernate to persist a class that looks like this:
public class Item implements Serializable, Comparable<Item> {
// Item id
private Integer id;
// Description of item in inventory
private String description;
// Number of items described by this inventory item
private int count;
//Category item belongs to
private String category;
// Date item was purchased
private GregorianCalendar purchaseDate;
public Item() {
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getCount() {
return count;
}
public void setCount(int count) {
this.count = count;
}
public String getCategory() {
return category;
}
public void setCategory(String category) {
this.category = category;
}
public GregorianCalendar getPurchaseDate() {
return purchaseDate;
}
public void setPurchasedate(GregorianCalendar purchaseDate) {
this.purchaseDate = purchaseDate;
}
My Hibernate mapping file contains the following:
<property name="puchaseDate" type="java.util.GregorianCalendar">
<column name="purchase_date"></column>
</property>
When I try to run, I get error messages indicating there is no getter function for the purchaseDate attribute:

I'm new to Hibernate, so I don't know all the ins and outs, but I do have the getter and setter for the purchaseDate attribute. I don't know what I'm missing here - does anyone else?
It came to me once without any typos. I've added javassist.jar to classpath and it solved the problem.
Further on down the stack trace, it says this:
missing a getter for puchaseDate
You might want to check for typos ;) You're missing an R and setPurchasedate should be setPurchaseDate
It looks like the problem is probably in the capitalization: setPurchasedate() should be setPurchaseDate() (with a capital "D").
If it can help someone:
In my case there were errors in my mapping files. Classes were not referenced by their full package names. I did this mistake because I generated the mappings when my bean classes belonged to the default package (hence no package name; e.g.: Order instead of com.mypackage.Order) and then I moved my bean classes to package (in the example com.mypackage). Unfortunately mapping files did not changed accordingly with the new package definition.
My hint is redo Hibernate reverse engineering and see what it produces, comparing it with your current mapping files.
Pay attention to method name,It is case sensitive!
In my case,it could not recognize getter very well; my property name was uId and I used getUId name for getter name and when I changed it to getuId problem solved!
I included java assit.jar and it worked
<dependency>
<groupId>javassist</groupId>
<artifactId>javassist</artifactId>
<version>3.12.1.GA</version>
</dependency>
I experienced the
Unable to instantiate default tuplizer [org.hibernate.tuple.entity.PojoEntityTuplizer]
because I had a momentary lapse of donkeyness when renaming a field on a POJO that I had previously mapped.
I changed the Java attribute name with my trusty IDE refactor hotkey, which does not also change the getter & setter method names. I changed the getter (because it caught my attention with its #Column annotation that I also needed to address because the table column name was changing).
I neglected, however, to change the setter, and that was the cause of the error.

I'm currently working with Springboot. now I want to query data by Java.util.date via JpaRepository and I have the following code in my interface.
List<MyEnity> findByDate(Date date);
I use Java.util.date and I have a personal reason that I couldn't change to java.time. I've ensured that
MyEntity Class in date field has TemporalType.DATE like this
#Temporal(TemporalType.DATE) private Date date;
and also the date field in MySQL is also date type
enter image description here
I tried to use the findByDate(Date date) method above and the date paramter in the method is obviously exist in my database but I always get an Empty List...
The other methods like findByName(String name) or findAll() work just fine.
I've tried to log the SQL statement from hibernate and I found that the binding parameter [DATE] might be in a different format? in my db is 'yyyy-mm-dd'
here is a log where I query with id and date. and at the bottom of the log I notice that the Id is binded with query statement, but date won't

Actually, there is no problem with Date binding that why query executed perfectly.
May be problem is Application Timezone and Database timezone is not matching.
You are sending DATE with IndoChina Timezone(ICT) Tue Apr 15 00:00:00 ICT 1477 but you are using serverTimezone=UTC(In JDBC Url) for database which means you are using UTC Timezone for Database.
So, you can change the timezone for database using serverTimezone=ICT to use IndoChina Timezone(ICT)
I am trying to test that my connection to Hibernate is working in my code so I set up a basic method to create a new entity in a table. When I run the code I don't see an error and when I first ran it Hibernate successfully created the table but the row is not being created in the table. Anyone know why this might be happening? Pasted User class and code to create below as well as logs.
public static void main(String[] args) {
Session session = SessionFactoryUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
User user = new User();
user.setPassword("abcd");
user.setStatus(UserStatus.OFFLINE);
user.setUserName("testuser");
session.save(user);
}
User class:
#Entity
#Table(name="USERS")
public class User {
#Id
#GeneratedValue(strategy=GenerationType.AUTO)
#Column(name="USER_ID")
private String userId;
#Column(name="USER_NAME")
private String userName;
#Column(name="PASSWORD")
private String password;
#Enumerated(EnumType.STRING)
#Column(name="STATUS")
private UserStatus status;
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;

return userName;
}
public void setUserName(String userName) {

}

However in Yohan2.docx, nothing is changed, it is a pure copy of Yohan.docx. What have I done wrong here?
UPDATE
I tested the MERGEFIELD example from the GITHUB but it also didn't work. Below is the output printed in console

docx4j has an API for replacing MERGEFIELD and DOCPROPERTY fields, but not CITATION fields.
Is there a particular reason you are trying to use a CITATION field?
If you can swap to MERGEFIELD or DOCPROPERTY field, I'd do that. Otherwise, you could examine docx4j's code for handling those, and adapt it to handling CITATION.

Copy merge field name as appears in the document together with the arrow characters to your code.

This program does tens of thousands of consecutive inserts one after the other. I've never used Hibernate before. I'm getting extremely slow performance (if I just connect and execute the SQL manually I am 10-12x quicker. My batch_size is set to 50 as per many hibernate tutorials.
Here is a log from a single insert - perhaps you could help me understand exactly what is happening:

FINISH INSERT
When you call session.save(), hibernate will generate an INSERT SQL. This INSERT SQL will be appended to be issued to the DB during flushing (i.e session.flush()) .
During flushing, if hibernate.jdbc.batch_size is set to some non-zero value, Hibernate will use the batching feature introduced in the JDBC2 API to issue the batch insert SQL to the DB .
For example , if you save() 100 records and your hibernate.jdbc.batch_size is set to 50. During flushing, instead of issue the following SQL 100 times :
insert into TableA (id , fields) values (1, 'val1');
insert into TableA (id , fields) values (2, 'val2');
insert into TableA (id , fields) values (3, 'val3');
.........................
insert into TableA (id , fields) values (100, 'val100');
Hiberate will group them in batches of 50 , and only issue 2 SQL to the DB, like this:
insert into TableA (id , fields) values (1, 'val1') , (2, 'val2') ,(3, 'val3') ,(4, 'val4') ,......,(50, 'val50')
insert into TableA (id , fields) values (51, 'val51') , (52, 'val52') ,(53, 'val53') ,(54, 'val54'),...... ,(100, 'val100')
Please note that Hibernate would disable insert batching at the JDBC level transparently if the primary key of the inserting table isGenerationType.Identity.
From your log: you save() only one record and then flush(), so there is only one appending INSERT SQL to be processed for every flush. That's why Hibernate cannot help you to batch inserting as there is only one INSERT SQL to be processed. You should save() up to the certain amount of records before calling flush() instead of calling flush() for every save().
The best practise of batch inserting is something like this:
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
for ( int i=0; i<888888; i++ ) {
TableA record = new TableA();
record.setXXXX();
session.save(record)
if ( i % 50 == 0 ) { //50, same as the JDBC batch size
//flush a batch of inserts and release memory:
session.flush();
session.clear();
}
}
tx.commit();
session.close();
You save and flush the records batch by batch. In the end of each batch you should clear the persistence context to release some memory to prevent memory exhaustion as every persistent object is placed into the first level cache (your JVM's memory). You could also disable the second-level cache to reduce the unnecessary overhead.
Reference:
Official Hibernate Documentation : Chapter 14. Batch processing
Hibernate Batch Processing – Why you may not be using it. (Even if you think you are)
If you must use hibernate for huge batch jobs StatelessSession is the way to go. It strips things down to the most basic converting-objects-to-SQL-statements mapping and eliminates all of the overhead of the ORM features you're not using when just cramming rows into the DB wholesale.
It would also be much easier to make suggestions on your actual code than the log :)
11:02:56.133 [main] DEBUG o.h.transaction.JDBCTransaction - commit
This is saying that the database is committing after every insert. Ensure you are not committing your transaction / closing your session inside the insert loop. Do this once at the end instead.
