Annotation processor to generate Hibernate DAO.
Auto generate DAO for @Entity classes with support for annotation driven validations, defaults, sorting, filtering and much more. Changes to the entity classes are automatically reflected in the generated DAO class, have cleaner codebases and simpler PR's.
Focus on codebase not on Predicates.
To generate a DAO annotate your @Entity class with @GenerateDao.
package com.example;
@GenerateDao //Annotation to generate DAO class
@Entity
public class Delivery {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
private String orderId;
private String customerName;
}Brahma-Dao creates a DAO with CRUD methods already generated and a basic search API. We provide a more in depth search api, filtering, sorting etc, please refer the Wiki to know more. You can always extend this class to add more custom functionality.
package com.example.dao;
public class Brahma_DeliveryDao extends AbstractDAO<Delivery> {
public Brahma_DeliveryDao(SessionFactory sessionFactory) {
super(sessionFactory);
}
public Delivery createOrUpdate(Delivery delivery) {
return persist(delivery);
}
public Delivery getById(Integer id) {
return get(id);
}
//Any attribute/column changes in the entity class are automatically reflected here
protected List<Predicate> getPredicateList(Delivery searchQuery,
CriteriaBuilder criteriaBuilder, Root<Delivery> from) {
List<Predicate> searchRestrictions = new ArrayList<>();
if (searchQuery.getId() != null) {
searchRestrictions.add(criteriaBuilder.equal(from.get("id"), searchQuery.getId()));
}
if (searchQuery.getOrderId() != null) {
searchRestrictions.add(criteriaBuilder.equal(from.get("orderId"), searchQuery.getOrderId()));
}
if (searchQuery.getCustomerName() != null) {
searchRestrictions.add(criteriaBuilder.equal(from.get("customerName"), searchQuery.getCustomerName()));
}
return searchRestrictions;
}
public List<Delivery> search(Delivery searchQuery) {
return getSearchQuery(searchQuery).list();
}
public Delivery searchUniqueResult(Delivery searchQuery) {
return getSearchQuery(searchQuery).uniqueResult();
}
}Create more powerful DAO's with support for validations, defaults, sorting, filtering and much more. Refer the Wiki to know more.
