ResourceServiceREST has been adapted to GenericRESTService. Updating functionality in ResourceServiceREST is not implemented yet.
As part of this patch, the generic infraestructure for REST services has been improved. In particular, recoverable error support has been provided. Exceptions representing recoverable errors must extend from RecoverableErrorException. To demonstrate this capability, ResourceServiceREST nows reports non-existent calendars, criterions, critetion types, and cost categories as recoverable errors.
IMPORTANT: "code" column has been added to tables of the following entitites: Resource, CriterionSatisfaction, and ResourcesCostCategoryAssignment. "code" column has been removed from Machine's table. In consequence, it is better to remove all the database when applying this patch (navaldev, navaldevtest, navalprod, and navaprodtest).
This change is compatible with the current Web user interface. The only thing you will notice is that when creating a machine, the form containing the code automatically displays a value in the code field (which, of course, can be changed by the user). Of course, the user interface should be improved to set a blank value or propose a more meaningful code to the user (probably this second option).
The service has not been adpated to GenericRESTService yet and duplicate codes in resources *being* imported are not detected yet (GenericRESTService will make this automatically).
GenericRESTService provides initial common functionality to all services. Some another generic infraestructure has been improved (IntegrationEntity, IIntegrationEntityDAO, InstanceConstraintViolationsDTO, and ConstraintViolationConverter) or simplified (IntegrationEntityDTO).
GenericRESTService does not implement all desirable features yet (e.g. recoverable errors). Please, do not use it yet.
CriterionServiceREST has been reimplemented in terms of it. Tests have also been improved.
Support for updating criterion types when importing criterion types has been added.
To update a criterion type, it is only necessary to send the modifications, and not all the state. In consequence, it is only necessary to send modified propert
ies in the criterions and the criterion type itself, and only new or modified cr
iterions need to be sent. Furthermore, any legal change in the criterion hierarchy of the criterion type is allowed.
Finally, a test case has been added to test the updating funcionality.
IMPORTANT: CriterionType and Criterion tables must be removed because they now need "code" column with non-null values. Any row in any other table refering to CriterionType and Criterion instances must also probably be removed. In consequence, it is probably better to remove all databases (navaldev, navaldevtest, navalprod and navalprodtest).
This first version does not implement updates yet (only insertions) and does not detect repeated codes in the entities being imported (repeated codes in database are detected). "code" attribute has now been added to entities, and "num-instance" + "code" + "entity-type" attribute has been added to InstanceConstraintViolationsDTO.
This effort has been implemented creating reusable classes (to facilitate migration of the rest of services) and with a non-invasive approach (to make possible migrate each service individually and minimize the number of changes to the current code [specially testing code]).
Some existing methods/attributes in existing reusable classes (e.g. Util, InstanceConstraintViolationsDTO) have been deprecated (to support migration of services incrementally) and new ones have been implemented.
New reusables clases have been implemented: IntegrationEntity (all entities used in application integration must extend from this one), IIntegrationEntityDAO, IntegrationEntityDAO, InstanceConstraintViolationsDTOId (identifier for an instance causing a list of constraint violations), and IntegrationEntityDTO (all entity DTOs must extend from this one). Please, have a look to the JavaDoc of such classes.
It illustrates an error when trying to add a resource with overlapping criterions satisfactions refering to the same criterion (even though its criterion type allows simultaneous criterion satisfactions). This case was already illustrated as a test case in ResourceServiceTest.
Please note that criterion satisfaction overlapping means: (1) if criterion satisfactions refer to the same Criterion, they must not overlap (regardless of its CriterionType allows simultaneous criterion satisfactions per resource), and (2) if CriterionType does not allow simultaneous criterion satisfactions per resource, criterion satisfactions (of the same type) must not overlap (regardless of they refer to different Criterion objects).
The following improvements have been implemented: (1) criterion type and criterion names are trimmed with StringUtils.trim, (2) case is ignored for criterion type and criterion names, (3) just one constraint violation is reported for a criterion type with a name already used by another criterion type being imported, (4) CriterionType::checkConstraintNonRepeatedCriterionNames now discards criterions with names fulfilling StringUtils.isBlank(criterionName), (5) Criterion::createUnvalidated and CriterionType::createUnvalidated now use BaseEntity::create (to avoid to call setNewObject and other possible future actions), and (6) assertTrue/assertFalse JUnit methods in CriterionServiceTest now make use of the toString method provided by constraint violations related DTOs (to make debugging easier).
Support for importing resources with cost assignments has been implemented. Many test cases have been implemented for checking all constraint violations in cost assigments (special care has been taken to check time interval overlappings). toString method has been implemented in constraint violation related DTOs to facilitate debuging in testing.
Resources to be imported can now specify a calendar name. Each resource will have a derived calendar of the specified one. Furthermore, test cases have been implemented for the most common cases (calendar not specified -> use default calendar, calendar specified, and non-existent calendar).
Resources with the same "logical" name (code for machines; first name, surnamne, and nif for workers) among the list of resources *being imported* are detected. This detection must be implemented at the service-level (at the entity-level, @AssertTrue annotations in Machine and Worker detect importation of resources with the same logical name as other resources already existing in the *database*). A test case has been added (furthermore, ResourceServiceTest has been refactorized a little bit).

Subject: [PATCH 6/7] ItEr41S15CUImportacionRecursosProductivosItEr40S20: Constraint added to verify criterion satisfactions are of a CriterionType compatible with the resource.
A test case has also been added.
@Valid has been specified in Resource::getCriterionSatisfactions. A test case has been added to verify a validation constraint is generated when a resource containing a criterion satisfaction without start date is being imported with the REST service (@Valid annotation is necessary).
Bug fixed when firstName, surname or nif are null in a worker to be imported with the REST service. Now, Worker::checkConstraintUniqueFirstName checks if such fields are null.
REST service for importing resources has been exported remotely. A script and a sample file with resources is also provided. Complex validations are not implemented yet.
The new foler includes a README file (please, update it when adding new scripts), common scripts (base64.sh and rest-common-env.sh), two scripts (post-criterions-types.sh and get-criterion-types.sh) for importing/exporting criterion types, and a sample file (criterion-types-sample.xml) with criterion types to be imported.
