Hi i am trying to insert a record in Mysql and get the ID of the inserted user in Spring boot JPA. i am getting following error. i have seen couple of questions like this but there they provided answer as USE JDBC Template for these kind of output. is it not possible to do it??. or this is related to some other issue.
Controller
#RequestMapping(value = "/signup", method = RequestMethod.POST)
public String createsignup(#RequestParam String name,#RequestParam String email,#RequestParam String password, ModelMap model) {
int userid = 0;
User user = new User(name,email);
userrepository.save(user);
userid = user.getId();
Authentication auth = new Authentication(email,password,userid);
authrepository.save(auth);
model.put("remember_token", auth.getRemember_token());
return "redirect:/profile";
}
Model

After lot of search and try i found that User Table is default table in Postgresql. that's why it did not allowed. i have changed the table name and it worked. is there any other way is there to reuse it ?.
Make sure you have specified the correct dialect for hibernate and MySQL. It seems that value for identity column can't be set correctly.
For instance, if you use Spring Boot, check your application properties for something like:
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect
Or if you use Spring MVC without Spring Boot, that you have:
hibernateJpa.setDatabasePlatform("org.hibernate.dialect.MySQL5Dialect");
in LocalContainerEntityManagerFactoryBean configuration.

I'm currently learning Hibernate and I'm stuck at fetching data from many-to-many relationship in hibernate (spring-jpa). I'm trying to get data by id and it just doesn't work.
I know it's not realistic but one book can be taken from many persons.
The problem is, it does not matter in which class I put fetch type EAGER and in the second I put LAZY fetch type, it's throwing:
LazyInitializationException: failed to lazily initialize a collection of role
But if I put EAGER fetch type in both classes is throwing a StackOverFlowError.
The many-to-many logic goes like this we have a books in library and we have persons and many persons can take many books and book can be taken from many persons.
I have tried to put EAGER fetching in both classes but it gives me StackOverFlowError.
I have to mention that I'm using the JpaRepository interface.
The Person class:
#Entity
#Table(name = "persons")
public class Person { // (in library)
#Id
#Column(name = "id")
#GeneratedValue(strategy= GenerationType.IDENTITY)
private int id;
#Column(name = "name")
private String name;
#Column(name = "number_card")
private int numberCard;
#Column(name = "time_of_account_creating")
#Temporal(TemporalType.DATE)
private Date date;
#ManyToMany(cascade=CascadeType.ALL, fetch = FetchType.EAGER)
List<Book> books = new ArrayList<>();
public Person() {
this.date = new Date();
}
public Person(String name, int numberCard) {
this.name = name;
this.numberCard = numberCard;
this.date = new Date();
}
public void addBook(Book book) {
this.books.add(book);
}
// gettters and setters
The Book class:
#Entity
#Table(name = "books")
public class Book { // (in library)
#Id
#Column(name = "id")
#GeneratedValue(strategy= GenerationType.IDENTITY)
private int id;
#Column(name = "release_year")
private int releaseYear;
#Column(name = "name")
private String name;
#ManyToMany(mappedBy = "books", cascade=CascadeType.ALL, fetch = FetchType.LAZY)
private List<Person> persons = new ArrayList<>();
public Book() {
}
public Book(int releaseYear, String name) {
this.releaseYear = releaseYear;
this.name = name;
}
public List<Person> getPersons() {
return persons;
}
public void addPerson(Person person) {
this.persons.add(person);
}
// getters and setters
Main method in the #SpringBootApplication:
public static void main(String[] args) {
ApplicationContext context = SpringApplication.run(HibernateDemoApplication.class, args);
PersonRepository personRepository = context.getBean(PersonRepository.class);
System.out.println(personRepository.findById(4));

And I have to say it again, I am getting a StackOverFlowError if I put EAGER fetch type in both classes.
I know this thread is a few months old, but for asker in the future:
Issue:
You hide the Person#toString method. In the method you access the books field. It is fine since the fetchtype is EAGER. The issue is that you access the Book#toString where you access the persons field. This field is LAZY. Since you will not access this field within transaction you will always get the LazyInitializationException.
Solution:
Open a transaction. (google jpa transaction)
Load the entity.
Access the lazy fields. It will work!
Close the transaction: Note, all changes applied to loaded entities within transaction will be save to database automaticallay, there is no need to save them through repository DAO manually!
I'm using an H2 embedded database for testing, and after the tests complete, I'm seeing the system trying to close the database twice and then it hangs waiting on the last log line shown here:

This is happening with Spring Boot 2.1.5 and 2.1.6
In the test class I set up the database this way
#RunWith(SpringRunner.class)
#SpringBootTest
#TestPropertySource(locations = "classpath:application.yml")
#Slf4j
public class DBTest {
...
static EmbeddedDatabase informixDB;
static JdbcTemplate informixJDBCTemplate;
#BeforeClass
public static void initDb() {
informixDB = new EmbeddedDatabaseBuilder().setType(EmbeddedDatabaseType.H2).build();
informixJDBCTemplate = new JdbcTemplate(informixDB);
ClassPathResource initSchema = new ClassPathResource("data/informix/InformixUp.sql");
DatabasePopulator databasePopulator = new ResourceDatabasePopulator(initSchema);
DatabasePopulatorUtils.execute(databasePopulator, informixDB);
}
#AfterClass
public static void dropDb() {
ClassPathResource drop = new ClassPathResource("data/informix/InformixDown.sql");
DatabasePopulator databasePopulator = new ResourceDatabasePopulator(drop);
DatabasePopulatorUtils.execute(databasePopulator, informixDB);
}
I have this in my test/application.yml though it seems to be being ignored
spring:
jpa:

I wanted to make use of #Transactional, expecting that annotated methods get a separate transaction which will be committed at the end of the method.
However, if I check the DB, there was nothing committed:
#Transactional
public boolean borrowLibraryItem(Long libraryUserId, Long uniqueLibraryItemNumber) {
boolean success = false;
LibraryUser borrower = libraryUserRepository.findByLibraryUserId(libraryUserId);
LibraryItem borrowItem = libraryItemRepository.findByUniqueLibraryItemNumber(uniqueLibraryItemNumber);
success = borrower != null && borrowItem != null;
if (success) {
BorrowedByRel borrowedByRel = new BorrowedByRel(borrower, borrowItem);
borrowedByRel.setBorrowDate(LocalDateTime.now());
borrowItem.setBorrowedByRel(borrowedByRel);
// libraryItemRepository.save(borrowItem);
}
return success;
}
The code commits the changes perfectly fine when using the repository.save-method, but not without.
Configuration is done via spring boot - as far as I understood, things should work out of the box this way (this might be the part where I got something wrong):
#SpringBootApplication
#EnableNeo4jRepositories(basePackages = "yalms.libraryapi.repositories")
#EntityScan("yalms.libraryapi.entities")
#EnableTransactionManagement
public class YalmsLibraryApplication {
public static void main(String[] args) {
SpringApplication.run(YalmsLibraryApplication.class, args);
}
}
Something regarding transactions seems to be happening, as the following logging.level.org.springframework.transaction.interceptor=TRACE shows:
Getting transaction for borrowLibraryItem()..
Don't need to create transaction for findByLibraryUserId, not transactional..
Request: MATCH (n:`LibraryUser`)..
Don't need to create transaction for findByUniqueLibraryItemNumber, not transactional..
Request: MATCH (n:`LibraryItem`)..
Completing transaction for borrowLibraryItem().
I would expect though that the changes (the addition of a relationship) would be committed. Am I misunderstanding something here or do I have something not configured right? Any help would be very much appreciated, thanks in advance!
UPDATE:
I've added a Neo4jTransactionManager-Bean as suggested in the comments, unfortunately it didn't help to solve my issue:
#Bean
public SessionFactory sessionFactory() {
org.neo4j.ogm.config.Configuration configuration = new org.neo4j.ogm.config.Configuration.Builder()
.uri(databaseUrl)
.credentials(userName, password)
.build();
return new SessionFactory(configuration,"yalms.libraryapi");
}
#Bean
public Neo4jTransactionManager transactionManager() {
return new Neo4jTransactionManager(sessionFactory());
}
I've enabled trace-output regarding everything coming from spring.data.*, and it's quite surprising to me as it seems that everything seems to be working fine:

But the update still does not end up in DB - makes kinda sense as there is no query that creates the new relation, but I do not understand why not: The retrieved entities seem to be attached to the transaction, the entities get modified within the transaction, so the changes should be committed once the transaction completes. Or did I misunderstand something here fundamentally?
Neo4j-OGM (the object graph mapper behind Spring Data Neo4j) needs an explicit save call. This is currently done by the explicit Spring Data Neo4j save call. There is no auto-commit when using Spring's transactional boundary.
Basically you have no error in your application and the explicit save call needs to be un-commented.
Some notes on the comments: You do not need to define a TransactionManager on your own within a Spring Boot applications. The spring-boot-starter-neo4j takes care of initialising Configuration, SessionFactory and an appropriate TransactionManager.
I have a spring boot app, it pulls in a jar which has two database configs, both mysql db's. Both databases look to be starting up correctly in the logs, but are not uniquely identified. It looks like default is registered and then reregistered so it appears to overwrite.

I have two classes for configuring the database connections, both of these are located in the imported jar, basically a common library.
#Configuration
#EnableTransactionManagement
#PropertySource(value = { "classpath:/${app.execution.environment}/application.properties" })
#EnableJpaRepositories(basePackages = "com.example", entityManagerFactoryRef = "mysqlEntityManager", transactionManagerRef = "mysqlTransactionManager")
#EntityScan(basePackages = { "com.example" })
public class MysqlHibernateConfig {
// beans configured here marked with #Primary
...
}
and
#Configuration
#EnableTransactionManagement
#PropertySource(value = { "classpath:/${app.execution.environment}/application.properties" })
#EnableJpaRepositories(basePackages = "com.example.another_package", entityManagerFactoryRef = "mysqlEntityManager2", transactionManagerRef = "mysqlTransactionManager2")
#EntityScan(basePackages = { "com.example.another_package" })
public class MysqlHibernateConfig2 {
...
}
I try to get data from each database through classes like this:
#Transactional("mysqlTransactionManager") // workspace complains about not being able to find this bean
#Service
public class PriceService {
}
#Transactional("mysqlTransactionManager2") // workspace complains about not being able to find this bean
#Service
public class PriceService2 {
}
PriceService gets data just fine, but PriceService2 tries to get data from mysqlTransactionManager instead of from mysqlTransactionManager2.
I also have the following classes to run my boot app:
#Configuration
#ComponentScan(basePackages = "com.example")
public class WebMvcConfig extends WebMvcConfigurerAdapter {
//config stuff
}
#SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
How can I force one class to use a specific transaction manager/data source? I have been trying various configs and as far as I can tell this is set up correctly. If I put both of these datasource config classes into my spring boot app, I can connect to the correct datasources no problem. But when I move them to an outside library it does not work. I have to keep these in a common library because of the structure of my projects, two separate apps use this database config.
I do have the freedom to move the non primary db into my spring boot app if necessary, but that is not working either. Ends up with the same result.
I'm using Wicket in combination with Spring and Hibernate, at least that's what I'm trying to do, the problem comes with auto generating the tables with Hibernate annotations.
I've been trying many changes in the configuration but can't seem to figure out why my configuration doesn't generate any tables. And I'm hoping someone can point me in the right direction, even about the Spring configuration I'm not sure.
I've included all the files I'm using to try to make this work in links, so that it won't be a very long list of configuration files.
I'm using the following class with annotations, http://schrealex.com/downloads/User.java:
#Entity
#Table(name="user")
public class User {
#Id
#Column(name="user_id", unique=true, nullable=false)
#GeneratedValue(strategy=GenerationType.AUTO)
private Long id;
#Column(name="username")
private String username;
#Column(name="password")
private String password;
#Column(name="firstname")
private String firstname;
#Column(name="lastname")
private String lastname;
#Column(name="birthDate")
private Date birthDate;
#Column(name="email")
private String email;
#Column(name="profile_image")
private String profile_image;
public User() {
}
public User(String username, String password, String email) {
this.username = username;
this.password = password;
this.email = email;
}
// Getter and Setter methods
}
I'm using the following dependencies described in my pom.xml:
http://schrealex.com/downloads/pom.xml
I'm using the following configuration in applicationContext.xml and properties:
http://schrealex.com/downloads/application.properties
http://schrealex.com/downloads/applicationContext.xml
And finally web.xml:
http://schrealex.com/downloads/web.xml
If I'm missing any files you'd like to see, just ask.

Edit :-
I tried renaming my User class to MediaUser and the #Table annotation to mediaUser to avoid problems with the USER word being reserved for some databases.
What I've found from the start up logging, as seen above, is that it does say it's running the export:
INFO - SchemaExport - Running hbm2ddl schema export
INFO - SchemaExport - exporting generated schema to database
INFO - SchemaExport - schema export complete
Also tried different approaches to the Hibernate annotations, like using other imports, #Table is now used by importing javax.persistence.Table, but I also tried the Hibernate org.hibernate.annotations.table, thus far without a solution to my problem.
I've found the answer to my problem, the annotations need either be set on the instance variables or on the class and it's methods and it needs to implement Serializable like:
#Entity
public class User implements Serializable {
#Id
#GeneratedValue
private Long id;
private String username;
private String password;
private String firstname;
private String lastname;
private Date birthDate;
private String email;
private String profileImage;
public User() {
}
public User(String username, String password, String email) {
this.username = username;
this.password = password;
this.email = email;
}
// Getter and Setter methods
#Column
public getUsername() {
return username;
}
#Column
public getPassword() {
return password;
}
#Column
public getFirstname() {
return firstname;
}
#Column
public getLastname() {
return lastname;
}
#Column
#Temporal(TemporalType.TIME)
public getBirthDate() {
return birthDate;
}
#Column
public getEmail() {
return email;
}
#Column
public getProfileImage() {
return profileImage;
}
}
I had the same problem ... in my case, the problem was because the USER word is reserved for some data bases.
So, considering that your hibernate configuration files are right, just add a prefix in all your tables and the problem was solved.
I hope this solve your problem too =)
Try to use
#EntityScan({" yourentitypackagehere "})
in your springboot application
