EntityManager JNDI Lookup

What is the correct JNDI string to look up this persistence unit JPA-DB that is shown on JBoss 6 Startup here:
10:26:09,847 INFO [PersistenceUnitDeployment] Starting persistence unit persistence.unit:unitName=tpar.ear/tpar-jboss-ejb3.jar#JPA-DB
10:26:09,847 INFO [Ejb3Configuration] Processing PersistenceUnitInfo [

I have tried the following and various others that I don't remember now and they all throw the NameNotFoundException:
entityManager = (EntityManager) jndi.lookup("java:/EntityManagers/JPA-DB");
entityManager = (EntityManager) jndi.lookup("java:comp/EntityManagers/JPA-DB");
entityManager = (EntityManager) jndi.lookup("java:comp/env/JPA-DB");
entityManager = (EntityManager) jndi.lookup("JPA-DB");

I was able to find the name by looking at the JNDI Tree view:
Go to http://localhost:8080/jmx-console
Search for JNDIView and click the link service=JNDIView
Invoke button for the list() method.
Search for the persistence name on the result tree view.
It looks like this:
Global JNDI Namespace
+- persistence.unit:unitName=tpar.ear (class: org.jnp.interfaces.NamingContext)
| +- tpar-jboss-ejb3.jar#JPADB (class: org.hibernate.impl.SessionFactoryImpl)
Though, the object is actually a SessionFactoryImpl and not an EntityManager.
Additionally, the jndi lookup string generated by JBoss is hideous:
jndi.lookup("persistence.unit:unitName=tpar.ear/tpar-jboss-ejb3.jar#JPADB");
By adding the following property to the persistence.xml, I can look up using a shorter name while getting the object as an EntityManager at the same time:
<property name="jboss.entity.manager.jndi.name" value="tpar/entity-manager"/>
Note that using the long JNDI name still returns SessionFactoryImpl object in case anyone wants a SessionFactory.

reload application context with all springboot test

I already add #SpringBootTest in all testcase.
'Run all test' in IDEA is OK, but when I use Maven test it didn't work.
how to reuse context in Maven test commend.
has any friend meet this problem? thx!
my test case like this:
#SpringBootTest
class EventControllerTest extends BaseTester{
...
}
#RunWith(SpringRunner::class)
#SpringBootTest
class BaseTester{}

Spring boot jpa data using wrong database

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.

Envers can't find audit tables

I want to use Envers in my project. The hardest part is to create audit tables. The database structure is created by flyway migrations. Therefore hibernate.hbm2ddl.auto = validate. According to the documentation I should use org.hibernate.envers.tools.hbm2ddl.EnversSchemaGenerator to create schema programmatically. But I didn't find any examples how to do it.
I created flyway migrations for audit tables. However seems like envers can't find them during the start for dev conf. Test conf works just fine. Here is my application.yml for dev:
spring.datasource:
driverClassName: com.mysql.jdbc.Driver
url: jdbc:mysql://localhost:3306/server?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8&connectionCollation=utf8&characterSetResults=UTF-8
username: root
spring.jpa:
database: MYSQL
show-sql: true
hibernate:
ddl-auto: validate
dialect: org.hibernate.dialect.MySQL5Dialect
naming_strategy: org.hibernate.cfg.ImprovedNamingStrategy
properties.org.hibernate.envers:
default_schema: server_audit
audit_table_suffix: _history
and Test:
spring:
profiles: test
spring.datasource:
driverClassName: org.h2.Driver
url: jdbc:h2:mem:test;MODE=MySQL;INIT=CREATE SCHEMA IF NOT EXISTS \"public\"\;CREATE SCHEMA IF NOT EXISTS \"SERVER_AUDIT\"
spring.jpa:
database: H2
show-sql: true
hibernate:
ddl-auto: validate
dialect: org.hibernate.dialect.H2Dialect
naming_strategy: org.hibernate.cfg.ImprovedNamingStrategy
During the start there is an exception:
java.sql.DatabaseMetaData : HHH000262: Table not found: accounts_history
[lication.main()] ationConfigEmbeddedWebApplicationContext : Exception encountered during context initialization - cancelling refresh attempt
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource
[org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.HibernateException: Missing table: accounts_history
Then I changed hbm2ddl.auto = update the output is weird:
java.sql.DatabaseMetaData : HHH000262: Table not found: accounts_history
org.hibernate.tool.hbm2ddl.SchemaUpdate : HHH000388: Unsuccessful: create table server_audit.accounts_history
org.hibernate.tool.hbm2ddl.SchemaUpdate : Table 'accounts_history' already exists
and it starts.
UPDATE
Can anyone provide example how to create audit tables using
org.hibernate.envers.tools.hbm2ddl.EnversSchemaGenerator
?

Hibernate does not generate table with annotations

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
