I'm currently building a advance search for a project using Specifications and Criteria Builder, I have multiple entities that I would like to create a generic class Specification builder. My question, is it possible to do it?
Entity example
#Entity
#Table(name = "marcas")
public class Brand implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer id;
#Column(name = "nombre")
private String name;
#Enumerated(EnumType.STRING)
#Column(name = "tipo_marca")
private Brandtype brandtype;
#Column(name = "fecha_creacion")
private LocalDateTime creationDate;
#Column(name = "fecha_actalizacion")
private LocalDateTime updateDate;
#OneToMany(
mappedBy = "brand",
fetch = FetchType.LAZY
)
private Set<Bike> bikes;
#OneToMany(
mappedBy = "brand",
fetch = FetchType.LAZY
)
private Set<Model> models;
#OneToMany(
mappedBy = "brand",
fetch = FetchType.LAZY
)
private Set<Accesorie> accesories;
public Brand() {
}
public Brand(Integer id, String name, Brandtype brandtype) {
this.id = id;
this.name = name;
this.brandtype = brandtype;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Brandtype getBrandtype() {
return brandtype;
}
public void setBrandtype(Brandtype brandtype) {
this.brandtype = brandtype;
}
public Set<Bike> getBikes() {
return bikes;
}
public void setBikes(Set<Bike> bikes) {
this.bikes = bikes;
}
public Set<Model> getModels() {
return models;
}
public void setModels(Set<Model> models) {
this.models = models;
}
public Set<Accesorie> getAccesories() {
return accesories;
}
public void setAccesories(Set<Accesorie> accesories) {
this.accesories = accesories;
}
public LocalDateTime getCreationDate() {
return creationDate;
}
public void setCreationDate(LocalDateTime creationDate) {
this.creationDate = creationDate;
}
public LocalDateTime getUpdateDate() {
return updateDate;
}
public void setUpdateDate(LocalDateTime updateDate) {
this.updateDate = updateDate;
}
#PrePersist
public void beforeCreate(){
this.creationDate = LocalDateTime.now();
}
#PreUpdate
public void beforeUpdate(){
this.updateDate = LocalDateTime.now();
}
#Override
public String toString() {
return "Brand{" +
"id=" + id +
", name='" + name + '\'' +
", brandtype=" + brandtype+
'}';
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Brand brand = (Brand) o;
return id.equals(brand.id) && name.equals(brand.name);
}
#Override
public int hashCode() {
return Objects.hash(id, name);
}
}
Reposotory example
#Repository
public interface BrandRepository extends PagingAndSortingRepository <Brand, Integer>, JpaSpecificationExecutor<Brand> {
}
Search Criteria class:
public class SearchCriteria {
private String key;
private String operation;
private Object value;
public SearchCriteria() {
}
public SearchCriteria(String key, String operation, Object value) {
this.key = key;
this.operation = operation;
this.value = value;
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
public String getOperation() {
return operation;
}
public void setOperation(String operation) {
this.operation = operation;
}
public Object getValue() {
return value;
}
public void setValue(Object value) {
this.value = value;
}
}
And this is the class Specification:
public class BrandSpecification implements Specification<Brand>{
private SearchCriteria criteria;
public BrandSpecification(SearchCriteria searchCriteria) {
this.criteria = searchCriteria;
}
#Override
public Predicate toPredicate(Root<Brand> root, CriteriaQuery<?> query, CriteriaBuilder builder) {
if (criteria.getOperation().equalsIgnoreCase(">")) {
return builder.greaterThanOrEqualTo(
root.<String> get(criteria.getKey()), criteria.getValue().toString());
}
else if (criteria.getOperation().equalsIgnoreCase("<")) {
return builder.lessThanOrEqualTo(
root.<String> get(criteria.getKey()), criteria.getValue().toString());
}
else if (criteria.getOperation().equalsIgnoreCase(":")) {
if (root.get(criteria.getKey()).getJavaType() == String.class) {
return builder.like(
root.<String>get(criteria.getKey()), "%" + criteria.getValue() + "%");
} else {
return builder.equal(root.get(criteria.getKey()), criteria.getValue());
}
}
return null;
}
public SearchCriteria getCriteria() {
return criteria;
}
public void setCriteria(SearchCriteria criteria) {
this.criteria = criteria;
}
}
I want to convert to generic so I can re use the code and dont need to rewrite it multiple times, can I have something like: public class GenericSpecification implements Specification<E>{}
You can do the following:
public class AppSpecification<T> implements Specification<T>{
private SearchCriteria criteria;
public AppSpecification(SearchCriteria searchCriteria) {
this.criteria = searchCriteria;
}
#Override
public Predicate toPredicate(Root<T> root, CriteriaQuery<?> query, CriteriaBuilder builder) {
if (criteria.getOperation().equalsIgnoreCase(">")) {
return builder.greaterThanOrEqualTo(
root.<T> get(criteria.getKey()), criteria.getValue().toString());
}
else if (criteria.getOperation().equalsIgnoreCase("<")) {
return builder.lessThanOrEqualTo(
root.<T> get(criteria.getKey()), criteria.getValue().toString());
}
else if (criteria.getOperation().equalsIgnoreCase(":")) {
if (root.get(criteria.getKey()).getJavaType() == String.class) {
return builder.like(
root.<T>get(criteria.getKey()), "%" + criteria.getValue() + "%");
} else {
return builder.equal(root.get(criteria.getKey()), criteria.getValue());
}
}
return null;
}
then you can initiate the class as follows:
var brandSpecification = new AppSpecification<Brand>(searchCriteria);

Can you check table details in sql , is it having "" quotes around it or single quotes
As i also faced same issue in my code , in that i was having table details as below
CREATE TABLE `orders` (
`id` INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
`firstname` VARCHAR(50) NOT NULL,
);
And i was accessing it with below bean
#Entity
#Table(name="orders")
public class Order {
#Id
#GeneratedValue
#Column(name="id")
private int id;
#Column(name="firstname")
private String firstName;
#OneToMany(targetEntity=OrderLine.class,
cascade = CascadeType.ALL,
fetch = FetchType.LAZY)
#JoinTable(
name="orderlines",
joinColumns = {#JoinColumn(table = "orderlines", name="FK_orders_orders",
referencedColumnName = "order_id")},
inverseJoinColumns={#JoinColumn(table = "orders", name="FK_orders_orders",
referencedColumnName = "id")}
)
After removing single quotes it started working for me

When you get Test and access Test.questions later, after leaving the transaction, you will get a lazy initialization exception when the Test entity is detached and questions has not been initialized/fetched yet. You can either do a specific fetch, or depending on your configuration, you can call Test.getQuestions().size() before you exit the transaction.

Basically you have to handle the Exception. Introduce a try catch block and output the appropriate message.
Handle the exception at the base level and funnel it to the controller.
I've been stuck here for almost a week trying find the answer on the internet but sadly nothing worked. :( Everytime I try to update using this method:
private Tenant updateTenantWithApplicationProperties(List<TenantApplicationProperty> newTenantApplicationProperties, String tenantId) {
String reason = "Update application properties.";
Tenant existingTenant = tenantRepository.findById(tenantId);
List<TenantApplicationProperty> temp = existingTenant.getTenantApplicationProperties();
existingTenant.setTenantApplicationProperties(newTenantApplicationProperties);
setApplicationPropertiesUpdateValues(temp, existingTenant);
if(newTenantApplicationProperties != null && newTenantApplicationProperties.size() != 0) {
Tenant savedTenantWithAppProps = saveTenantWithLog(existingTenant, reason);
return savedTenantWithAppProps;
}
return existingTenant;
}
Im always getting this error:
javax.persistence.PersistenceException: org.hibernate.PersistentObjectException: detached entity passed to persist: com.infor.ecom.tenant.manager.model.entity.ApplicationProperty
at org.hibernate.ejb.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1361)

But when Im using this method it works fine:
public Tenant updateTenant(Tenant tenant) {
List<Database> databases = tenant.getDatabases();
List<Administrator> administrators = tenant.getAdministrators();
validateUpdateTenant(tenant);
validateDatabases(databases);
validateAdministrators(administrators);

tenant);

setEcomDBParamsDefaultValues(tenant);
setAdministratorDefaultValues(tenant);
Database updateEcomDb = getDatabaseByType(tenant.getDatabases(),
TenantManagerConstants.ECOM_DATASOURCE);
Boolean shouldInstallNewDB = true;
if (existingEcomDb.getName().equalsIgnoreCase(updateEcomDb.getName())
&& existingEcomDb.getHost().equalsIgnoreCase(
updateEcomDb.getHost())
&& existingEcomDb.getPort().equals(updateEcomDb.getPort())) {
shouldInstallNewDB = false;
} else {
testEcomDBConnection(updateEcomDb);
}
int ecomDbTableCount = getEcomDBTableCount(updateEcomDb);
String[][] languages = formatAndValidateLanguages(updateEcomDb
.getEcomDatabaseParameters().getLanguages());
Tenant updatedTenant = saveExistingTenant(tenant);
if (updatedTenant != null) {
if (shouldInstallNewDB || ecomDbTableCount == 0) {
installDatabase(updateEcomDb, languages, updatedTenant);
} else {
updateDatabase(updateEcomDb, languages, updatedTenant);
}
storageService.updateTenantFolderStructure(updatedTenant);
} else {
throw new TenantManagerException(

return updatedTenant;

In application property, you defined 1-1 relation like:
#OneToOne
#JoinColumn(name = "property_group_id")
private ApplicationPropertyGroup applicationPropertyGroup;
#OneToOne
#JoinColumn(name = "property_type_id")
private ApplicationPropertyType applicationPropertyType;
While you have not defined the same relation (note it should work bidirectionally i.e. say for e.g. if you as a person related to an employee id, then employee id is related to you as a person well) in individual property ApplicationPropertyGroup and ApplicationPropertyType.
You should add the same 1-1 relation in ApplicationPropertyGroup and ApplicationPropertyType with ApplicationProperty.
