jpa-2.1

I am trying to map native SQL result to my POJO. Here is the configuration. I am using spring. <bean id="ls360Emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" > <property name="dataSource" ref="ls360DataSource" /> <property name="jpaVendorAdapter" ref="vendorAdaptor" /> <property name="packagesToScan" value="abc.xyz"/> <property name="jpaProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop> <prop key="hibernate.max_fetch_depth">3</prop> <prop key="hibernate.jdbc.fetch_size">50</prop> <prop key="hibernate.jdbc.batch_size"

Two years ago I was working on a project using: spring 4.0.3.RELEASE jpa 2.0 hibernate 4.2.7.Final java 1.6.X This project has a maven task hibernate3-maven-plugin which allow us to generate a database schema without any connection to a database (MySQL). Now we are upgrading this project with: java 1.8 jpa 2.1 spring 4.2.4.RELEASE hibernate 5.0.6.Final I understand that hibernate3-maven-plugin does not work on JPA 2.1 and hibernate > 4.3. All the solution I have found need a connection to a database. For instance: Auto generate data schema from JPA annotated entity classes . Does anyone know

I have a Spring repository as follows: import org.springframework.data.repository.Repository; import org.springframework.stereotype.Component; import com.test.domain.My; @Component public interface MyRepository extends Repository<My, String> { My findOne(String code); My findByName(String name); } The entity class is: import javax.persistence.ColumnResult; import javax.persistence.ConstructorResult; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.SqlResultSetMapping; import javax.persistence.Table; import com.fasterxml.jackson.annotation.JsonCreator;

I already went through the below few links, but it did not solved my problem: Java Jackson: deserialize complex polymorphic object model: JsonMappingException: Unexpected token (START_OBJECT), expected VALUE_STRING Java Jackson - Unexpected token (START_ARRAY), expected VALUE_STRING In my project, we've 15 batch jobs. I am converting 15 batch jobs into 15 different micro-services. For that I have created one Spring Boot module, which has Entity classes, JPA repository layer and service layer. That jar I will import into each micro-services (batch jobs), so that batch job should work fine. I am

I am testing JPA2.1 and the new "schema generation" feature. For that, I tested two implementations under the HyperSQL database : EclipseLink 2.5.2-M1 which is the reference implementation. Hibernate 4.3 I don't have any preference for an implementation (not even for performance). I tested EclipseLink because it was the first JPA2.1 implementation available, but now, Hibernate 4.3 is here and JPA2.1 compliant. The only thing I want is to get something independent from the JPA provider - except for the configuration (like cache, logging, static weaving, ...). As for schema generation, several

I have a table named group_table in MySQL with only two columns user_group_id and group_id (both of them are of type VARCHAR ). Both of these columns together form a composite primary key. I need to execute a statement using a sub-select IN() to select rows based on a list of values passed to the query. @Override @SuppressWarnings("unchecked") public List<GroupTable> getList(List<GroupTable> list) { CriteriaBuilder criteriaBuilder=entityManager.getCriteriaBuilder(); CriteriaQuery<GroupTable> criteriaQuery=criteriaBuilder.createQuery(GroupTable.class); Root<GroupTable> root = criteriaQuery.from
