hibernate

问题 Iam forced to apply this question because everything else documented is not working. Goal: To log SQL statements as they are executed in the DB along with their bounded variables. Environment: Payara 5.182, Hibernate 5.3.2, SLF4j with Logback. It seems that the official approach is NOT to touch the persistence.xml to enable hibernate logging but to properly configure the logging framework. pom.xml <!-- Logging --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic<

问题 I am developing an application using Struts 2 and Hibernate. On a JSP page I have one form in which all CRUD operations I am performing. I want my Form data to be persisted, which is temporarily entered in the form fields. One approach which I tried is to bind all the data into an Object and store that object in a session or cache but I know there is some limitation of storing data like this. My form is having the functionality to add n number of rows which means I have to store large amount

For example: builder.like( root.get(Book_.name) , search) Book_ can not be resolved as variable. Now I have followed this http://hibernate.org/orm/tooling/ and added <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-jpamodelgen</artifactId> <version>5.2.6.Final</version> </dependency> As it stated here

问题 Assume I have a Entity called Product . I design a Repo as @Repository interface ProductRepository implements JPARepository<Product, Integer>{} This would inherit all the default methods such as save, findAll etc; Now I want to have one custom method, which is also a common method for other entities. I added another interface and implementation interface CustomRepository<T,ID>{ public void customMethod() } class CustomRepositoryImpl implements CustomRepository<T,ID>{ public void customMethod(

问题 I am creating some simple Spring Boot project with Hibernate JPA. I created some data model which consists 5 tables for now and created entities reflecting tables. I have set spring.jpa.generate-ddl=true and my entities was correctly reflected by schema created in PostgreSQL. Next step was to start adding relations. Part of my assumed datamodel is (paron my UML) Very simple one to many relation. My entities look that way (getters and setters omitted below, exist in code): @Entity public class

问题 I have a problem with sending an object with values from inputs fields to controller in add user method. It generates an error ("Bad request") caused by a select box.
