org.hibernate.service.UnknownUnwrapTypeException: Cannot unwrap to requested type [javax.sql.DataSource] - java

I am getting this error while running my application : org.hibernate.service.UnknownUnwrapTypeException: Cannot unwrap to requested type [javax.sql.DataSource]
My configuration class :
#Configuration
#PropertySource("classpath:META-INF/spring/jdbc.properties")
public class HibernateConfig {
#Autowired
private Environment env;
#Bean(name="dataSource")
public DataSource getDataSource() throws PropertyVetoException{
ComboPooledDataSource dataSource = new ComboPooledDataSource();
dataSource.setDriverClass(env.getProperty("db.driverClass"));
dataSource.setJdbcUrl(env.getProperty("db.jdbcUrl"));
dataSource.setUser(env.getProperty("db.user"));
dataSource.setPassword(env.getProperty("db.password"));

dataSource.setAutoCommitOnClose(false);
dataSource.setInitialPoolSize(5);
return dataSource;
}
#Bean(name="sessionFactory")
#Scope("singleton")
public LocalSessionFactoryBean getSessionFactory(DataSource dataSource){
LocalSessionFactoryBean localSessionFactoryBean = new LocalSessionFactoryBean();
Properties hibernateProperties = new Properties();
hibernateProperties.setProperty("hibernate.dialect", env.getProperty("db.dialect"));
hibernateProperties.setProperty("hibernate.jdbc.batch_size", "0");
hibernateProperties.setProperty("c3p0.acquire_increment", "1");
localSessionFactoryBean.setHibernateProperties(hibernateProperties);
return localSessionFactoryBean;
}
#Bean(name="transactionManager")
public HibernateTransactionManager getTransactionManager(SessionFactory sessionFactory){
HibernateTransactionManager transactionManager = new HibernateTransactionManager();
transactionManager.setSessionFactory(sessionFactory);
return transactionManager;
}
}
I ran actually into this thread which talks about the same issue. However I am wondering if it is a sort of bug in hibernate5 that has not been fixed yet or does it relate to something else. Thank you in advance.

Pls give me advise, how to insert in database the binary data, like a zip file that is located in the resource folder.
I know that in unit test we can use annotation #Before which give us opportunity to do what you want. But how do it when you start your app with java config.
I have also faced the same issue.
This answer worked for me. You can try it, I think this will work for you.

Multiple database connection reusing entity mapping

We have a case where we connect to different databases environments, but the tables in each of the environment are the same.
Is there any way I can reuse the entity class for each of the environment?
I am using separate config class for each of the environment. Below is the config for one of the environment, similarly I have 4 others. The "packages" deduce which environment to connect to.
codejava
#Configuration
#EnableJpaRepositories(basePackages = {"packages"},
entityManagerFactoryRef = "OneEntityManager",
transactionManagerRef = "OneTransactionManager")
public class DevDataSourceConfig {
#Bean
#Primary
public LocalContainerEntityManagerFactoryBean OneEntityManager() {
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(OneDataSource());
em.setPackagesToScan(String[]{"packages"});
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
em.setJpaVendorAdapter(vendorAdapter);
HashMap<String, Object> properties = new HashMap<>();
properties.put("hibernate.hbm2ddl.auto", env.getProperty("hibernate.hbm2ddl.auto"));
properties.put("hibernate.dialect", env.getProperty("hibernate.dialect"));
em.setJpaPropertyMap(properties);
return em;
}
#Primary
#Bean
public DataSource OneDataSource() {
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setDriverClassName(driverclass);
dataSource.setUrl(url);
dataSource.setUsername(uName);
dataSource.setPassword(dbPass);
return dataSource;
}
#Primary
#Bean
public PlatformTransactionManager OneTransactionManager() {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(OneEntityManager().getObject());
return transactionManager;
}
}

Configure Hibernate models discovery in Spring

I want to configure Spring with Hibernate 5 and JNDI using this code:
#Configuration
#EnableTransactionManagement
public class ContextDatasource {
#Bean
public LocalSessionFactoryBean sessionFactory() throws NamingException {
LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();
sessionFactory.setDataSource(dataSource());
sessionFactory.setPackagesToScan("org.database.models");
sessionFactory.setHibernateProperties(hibernateProperties());
return sessionFactory;
}
#Bean
public PlatformTransactionManager hibernateTransactionManager() throws NamingException {
HibernateTransactionManager transactionManager
= new HibernateTransactionManager();
transactionManager.setSessionFactory(sessionFactory().getObject());
return transactionManager;
}
private final Properties hibernateProperties() {
Properties hibernateProperties = new Properties();
hibernateProperties.setProperty(
"hibernate.show_sql", "true");
hibernateProperties.setProperty(
"hibernate.format_sql", "true");
hibernateProperties.setProperty(
"hibernate.hbm2ddl.auto", "create-drop");
hibernateProperties.setProperty(
"hibernate.dialect", "org.hibernate.dialect.MariaDBDialect");
return hibernateProperties;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory()
throws NamingException {
LocalContainerEntityManagerFactoryBean em
= new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource());
return em;
}
#Bean
public DataSource dataSource() throws NamingException {
return (DataSource) new JndiTemplate().lookup("java:/global/production_gateway");
}
#Bean
public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(emf);
return transactionManager;
}
}
But when I deploy the code I get error. Looks like I have to add another XML configuration file:
Caused by: java.lang.IllegalStateException: No persistence units parsed from {classpath*:META-INF/persistence.xml}
Hibernate models are located in a remote jar under Java package org.database.models How I can map them using Java code?
May you need to add dependencies to your pom file, if you use maven
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>5.1.0.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.1.0.Final</version>
</dependency>
To prevent hibernate persistence.xml usage, you must define on LocalContainerEntityManagerFactoryBean the packages to scan entity from.
emf.setPackagesToScan(myPackagesToScan);

Jhipster Multi-tenancy with Hibernate Second Level Caching

I've been attempting to turn my JHipster generated application into a multi-tenancy app using this - http://jannatconsulting.com/blog/?p=41 blog post as a base.
I've run into a problem with second level caching. Spring boot appears to correctly detect and set up:
DatabaseConfiguration.java
#Configuration

public DataSource dataSource(DataSourceProperties dataSourceProperties, JHipsterProperties jHipsterProperties) {
log.debug("Configuring Master Datasource");
if (dataSourceProperties.getUrl() == null) {
log.error("Your database connection pool configuration is incorrect! The application" +
" cannot start. Please check your Spring profile, current profiles are: {}",
Arrays.toString(env.getActiveProfiles()));
throw new ApplicationContextException("Database connection pool is not configured correctly");
}
HikariConfig config = new HikariConfig();
config.setDataSourceClassName(dataSourceProperties.getDriverClassName());
config.addDataSourceProperty("url", dataSourceProperties.getUrl());
if (dataSourceProperties.getUsername() != null) {
config.addDataSourceProperty("user", dataSourceProperties.getUsername());
} else {
config.addDataSourceProperty("user", ""); // HikariCP doesn't allow null user
}

config.addDataSourceProperty("prepStmtCacheSize", jHipsterProperties.getDatasource().getPrepStmtCacheSize());
config.addDataSourceProperty("prepStmtCacheSqlLimit", jHipsterProperties.getDatasource().getPrepStmtCacheSqlLimit());
}
if (metricRegistry != null) {
config.setMetricRegistry(metricRegistry);
}
return new HikariDataSource(config);
}
#Bean(name = "masterEntityManager")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(){
JpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource(datasourceProperties, jhipsterProperties));

em.setJpaVendorAdapter(vendorAdapter);
em.setJpaProperties(additionalJpaProperties());
em.setPersistenceUnitName("master");
return em;
}
private Properties additionalJpaProperties() {

for (Map.Entry<String, String> entry : jpaProperties.getHibernateProperties(dataSource).entrySet()) {
properties.setProperty(entry.getKey(), entry.getValue());
}
return properties;
}
#Bean(name = "masterTransactionManager")
public JpaTransactionManager transactionManager(EntityManagerFactory masterEntityManager){
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(masterEntityManager);
return transactionManager;
}
}
When spring tries to configure:
MultiTenancyJPAConfiguration.java
#Configuration
#EnableConfigurationProperties(JpaProperties.class)
#EnableJpaRepositories(
entityManagerFactoryRef = "tenantEntityManager",
transactionManagerRef = "tenantTransactionManager",
basePackages = {"com.quadrimular.nts.helium.repository.tenant"})
#EnableTransactionManagement
public class MultiTenancyJpaConfiguration {
#Bean(name = "tenantEntityManager")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource,
MultiTenantConnectionProvider connectionProvider,

LocalContainerEntityManagerFactoryBean emfBean = new LocalContainerEntityManagerFactoryBean();
emfBean.setDataSource(dataSource);
emfBean.setPackagesToScan("com.quadrimular.nts.helium.domain.tenant");
emfBean.setJpaVendorAdapter(jpaVendorAdapter());
Map<String, Object> properties = new HashMap<>();
properties.put(org.hibernate.cfg.Environment.MULTI_TENANT, MultiTenancyStrategy.DATABASE);
properties.put(org.hibernate.cfg.Environment.MULTI_TENANT_CONNECTION_PROVIDER, connectionProvider);
properties.put(org.hibernate.cfg.Environment.MULTI_TENANT_IDENTIFIER_RESOLVER, tenantResolver);
properties.put("hibernate.ejb.naming_strategy", "org.hibernate.cfg.ImprovedNamingStrategy");
emfBean.setJpaPropertyMap(properties);
return emfBean;
}
#Bean(name = "tenantTransactionManager")
public JpaTransactionManager transactionManager(EntityManagerFactory tenantEntityManager){
JpaTransactionManager transactionManager = new JpaTransactionManager();
transactionManager.setEntityManagerFactory(tenantEntityManager);
return transactionManager;
}
}
I'm getting this in my trace:
Caused by: org.hibernate.cache.NoCacheRegionFactoryAvailableException: Second-level cache is used in the application, but property hibernate.cache.region.factory_class is not given; please either disable second level cache or set correct region factory using the hibernate.cache.region.factory_class setting and make sure the second level cache provider (hibernate-infinispan, e.g.) is available on the classpath.
I have all the required properties defined in my application-dev.yml
hibernate.cache.use_second_level_cache: true
hibernate.cache.use_query_cache: false
hibernate.generate_statistics: true
hibernate.cache.region.factory_class: org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory
It appears that it's being read and used correctly by spring boot for my DatabaseConfiguration.java. I can't work out why it's not detecting the property file. If I try to disable the cache by setting:
hibernate.cache.use_second_level_cache: false
DatabaseConfiguration.java detects and behaves accordingly however MultiTenancyJPAConfiguration.java still throws the same exception.
Am I missing something obvious?
The answer is to actually set the jpa property values on the entity manager. I'm not sure how I overlooked this; I thought that somehow they were already set.
Firstly I injected the main datasource and the jpa properties object provided by spring boot if I'm not mistaken.
MultiTenancyJPAConfiguration.java
#Inject
private JpaProperties jpaProperties;
#Inject
private DataSource dataSource;
I then set the values using the same method used in DatabaseConfiguration.java
MultiTenancyJPAConfiguration.java
#Bean(name = "tenantEntityManager")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource,
MultiTenantConnectionProvider connectionProvider,
CurrentTenantIdentifierResolver tenantResolver) {
LocalContainerEntityManagerFactoryBean emfBean = new LocalContainerEntityManagerFactoryBean();
emfBean.setDataSource(dataSource);
emfBean.setPackagesToScan("com.quadrimular.nts.helium.domain.tenant");
emfBean.setJpaVendorAdapter(jpaVendorAdapter());
Map<String, Object> properties = new HashMap<>();
properties.put(org.hibernate.cfg.Environment.MULTI_TENANT, MultiTenancyStrategy.DATABASE);
properties.put(org.hibernate.cfg.Environment.MULTI_TENANT_CONNECTION_PROVIDER, connectionProvider);
properties.put(org.hibernate.cfg.Environment.MULTI_TENANT_IDENTIFIER_RESOLVER, tenantResolver);
properties.put("hibernate.ejb.naming_strategy", "org.hibernate.cfg.ImprovedNamingStrategy");
emfBean.setJpaPropertyMap(properties);
emfBean.setJpaProperties(additionalJpaProperties());
return emfBean;
}
private Properties additionalJpaProperties() {
Properties properties = new Properties();
for (Map.Entry<String, String> entry : jpaProperties.getHibernateProperties(dataSource).entrySet()) {
properties.setProperty(entry.getKey(), entry.getValue());
}
return properties;
}
Using the method additionalJpaProperties() to get all the hibernate jpa properties for my main datasource. I then set the hibernate property map properties after the hard coded ones. Clearly not the cleanest solution I plan to set all jpa values from the .yml file.

Atomikos + OpenJpa +DB2 XA standalone - setAutocommit(true) not allowed

I have a spring batch project and am using Atomikos for transaction management.
Here is my datasource configuration and atomikos configuration.
#Bean

properties.setProperty("serverName", "localhost");
properties.setProperty("databaseName", "somedb");

properties.setProperty("driverType", "4");
properties.setProperty("resultSetHoldability","2");
AtomikosDataSourceBean atomikosDataSourceBean = new AtomikosDataSourceBean();
atomikosDataSourceBean.setXaDataSourceClassName("com.ibm.db2.jcc.DB2XADataSource");
atomikosDataSourceBean.setXaProperties(properties);
atomikosDataSourceBean.setPoolSize(5);
return atomikosDataSourceBean;
}
#Bean(initMethod = "init", destroyMethod = "close")
public UserTransactionManager atomikosTransactionManager(){
UserTransactionManager atomikosTransactionManager = new UserTransactionManager();
atomikosTransactionManager.setForceShutdown(false);
return atomikosTransactionManager;
}
#Bean
public UserTransactionImp atomikosUserTransaction() throws SystemException{
UserTransactionImp atomikosUserTransaction = new UserTransactionImp();
atomikosUserTransaction.setTransactionTimeout(300);
return atomikosUserTransaction;
}
#Bean
public JtaTransactionManager transactionManager(UserTransactionManager atomikosTransactionManager, UserTransactionImp atomikosUserTransaction) throws SystemException{
JtaTransactionManager jtaTransactionManager = new JtaTransactionManager();
jtaTransactionManager.setTransactionManager(atomikosTransactionManager);
jtaTransactionManager.setUserTransaction(atomikosUserTransaction);
jtaTransactionManager.setAllowCustomIsolationLevels(true);
return jtaTransactionManager;
}
#Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource) {
final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource);
em.setJtaDataSource(dataSource);
em.setPackagesToScan("org.company.entity");
em.setJpaVendorAdapter(new OpenJpaVendorAdapter());
em.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver());
em.setSharedCacheMode(SharedCacheMode.ALL);
em.setJpaProperties(additionalProperties());
return em;
}
final Properties additionalProperties() {
final Properties openJpaProperties = new Properties();
openJpaProperties.setProperty("javax.persistence.transactionType","jta");
openJpaProperties.setProperty("openjpa.TransactionMode", "local");
openJpaProperties.setProperty("openjpa.ConnectionFactoryMode", "local");
openJpaProperties.setProperty("openjpa.MetaDataRepository", "Preload=true");
openJpaProperties.setProperty("openjpa.Compatibility", "QuotedNumbersInQueries=true");
openJpaProperties .setProperty("openjpa.ConnectionFactoryProperties", "PrettyPrint=true, PrettyPrintLineLength=80, PrintParameters=true");
return openJpaProperties;
}
When i call spring repository to update the database it throws me an error saying Invalid operation: setAutoCommit(true) is not allowed during Global Transaction. See stacktrace below. Any thoughts on this will be very helpful.
com.ibm.db2.jcc.am.SqlException: [jcc][t4][10126][10304][3.62.56] Invalid operation: setAutoCommit(true) is not allowed during Global Transaction. ERRORCODE=-4201, SQLSTATE=2D521

I was able to fix it. The issue here is we need to tell openJpa to participate in Atomikos transactions. Here is a updated version of the additionalProperties() method:
#Bean
#DependsOn("transactionManager")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, JpaVendorAdapter jpaVendorAdapter,
TransactionManager transactionManager) {
final LocalContainerEntityManagerFactoryBean em = new LocalContainerEntityManagerFactoryBean();
em.setDataSource(dataSource);
em.setJtaDataSource(dataSource);
em.setPackagesToScan("org.company.entity");
em.setJpaVendorAdapter(jpaVendorAdapter);
em.setLoadTimeWeaver(new InstrumentationLoadTimeWeaver());
em.setSharedCacheMode(SharedCacheMode.ALL);
em.setJpaProperties(additionalProperties(dataSource, transactionManager));
return em;
}
final Properties additionalProperties(DataSource dataSource, TransactionManager transactionManager) {
final Properties openJpaProperties = new Properties();
openJpaProperties.put("javax.persistence.transactionType", "JTA");
openJpaProperties.put("openjpa.TransactionMode", "managed");
openJpaProperties.put("openjpa.ConnectionFactoryMode", "managed");
openJpaProperties.put("openjpa.ConnectionFactory", dataSource);
openJpaProperties.put("openjpa.ManagedRuntime", "invocation(TransactionManagerMethod=com.atomikos.icatch.jta.TransactionManagerImp.getTransactionManager)");
openJpaProperties.put("openjpa.MetaDataRepository", "Preload=true");
openJpaProperties.put("openjpa.Compatibility", "QuotedNumbersInQueries=true");
openJpaProperties.put("openjpa.ConnectionFactoryProperties", "PrettyPrint=true, PrettyPrintLineLength=80, PrintParameters=true");
return openJpaProperties;
}
