                                                                                                                                               com.fasterxml.jackson.core.JsonProcessingException

Parameters:

jsonObject -

entity -

Returns:

Throws:

IOException

com.fasterxml.jackson.core.JsonProcessingException

findById

@PostAuthorize(value="hasRole(@configHolder.getSuperAdminRoleName()) or hasPermission(returnObject, \'READ\')")
 @Transactional(readOnly=true)
public E findById(Integer id)

Return the real object from the database. Returns null if the object does not exist.

Parameters:

id -

loadById

@PostAuthorize(value="hasRole(@configHolder.getSuperAdminRoleName()) or hasPermission(returnObject, \'READ\')")
 @Transactional(readOnly=true)
public E loadById(int id)

Return a proxy of the object (without hitting the database). This should only be used if it is assumed that the object really exists and where non-existence would be an actual error.

Parameters:

id -

findAll

@PostFilter(value="hasRole(@configHolder.getSuperAdminRoleName()) or hasPermission(filterObject, \'READ\')")
 @Transactional(readOnly=true)
public List<E> findAll()

findAllRestricted

@PostFilter(value="hasRole(@configHolder.getSuperAdminRoleName()) or hasPermission(filterObject, \'READ\')")
public List<E> findAllRestricted(org.springframework.util.MultiValueMap<String,String> restrictToRequest)

Returns all entities, but possibly with only the passed fields set with actual values.

findBySimpleFilter

@PostFilter(value="hasRole(@configHolder.getSuperAdminRoleName()) or hasPermission(filterObject, \'READ\')")
 @Transactional(readOnly=true)
public List<E> findBySimpleFilter(org.springframework.util.MultiValueMap<String,String> requestedFilter)

Finds all entities that match the given filter (multi value map).

Each key in the multi value map is the name of a field/property of the entity. These values may be case insensitive! Each field name is mapped to a list of values (passed as Strings).

Fields that do not exist in the entity will be ignored.

Example:

 int=['1','2']
 string=['foo']
 bool1=['0']
 bool2=['true']
 

would be translated to a filter like (values are casted to the target type of the field)

 (int == 1 || int == 2) && (string == 'foo') && (bool1 == false) && (bool2 == true)
 

and return all entities that match this condition.

This will only work on simple properties of an entity.

The optional special key can contain a comma separated list of fieldNames you want to be filled with actual values. If you e.g. pass output:only=id,Name, the returned object will have all other fields being set to null, except for id and name (Notice how casing does not matter).

Parameters:

requestedFilter -

Returns:

findAllWhereFieldEquals

@PostFilter(value="hasRole(@configHolder.getSuperAdminRoleName()) or hasPermission(filterObject, \'READ\')")
 @Transactional(readOnly=true)
public List<E> findAllWhereFieldEquals(String fieldName,
                                                                                                                                                                                   Object fieldValue)

Returns a list of entity objects that have field named fieldName, which has an object fieldEntity as value.

Parameters:

fieldName - The name of the field

fieldValue - The element that should be set as value

Returns:

The list of objects

findAllWithCollectionContaining

@PostFilter(value="hasRole(@configHolder.getSuperAdminRoleName()) or hasPermission(filterObject, \'READ\')")
 @Transactional(readOnly=true)
public List<E> findAllWithCollectionContaining(String fieldName,
                                                                                                                                                                                           PersistentObject subElement)

Returns a list of entity objects that have a collection named fieldName, which contains the passed subElement.

The can e.g. be used to return all applications that contain a certain layer.

Parameters:

fieldName - The name of the collection field

subElement - The element that should be contained in the collection

Returns:

The list of objects

delete

@PreAuthorize(value="hasRole(@configHolder.getSuperAdminRoleName()) or hasPermission(#e, \'DELETE\')")
public void delete(E e)

Parameters:

e -
