        <artifactId>tools.dynamia.modules.entityfiles.s3</artifactId>
        <version>7.4.0</version>
    </dependency>

Gradle

compile 'tools.dynamia.modules:tools.dynamia.modules.entityfiles:7.4.0'
compile 'tools.dynamia.modules:tools.dynamia.modules.entityfiles.ui:7.4.0'
compile 'tools.dynamia.modules:tools.dynamia.modules.entityfiles.s3:7.4.0'

Usage

Add a field of type tools.dynamia.modules.entityfile.domain.EntityFile in your JPA entity with association @OneToOne

import tools.dynamia.modules.entityfile.domain.EntityFile;

@Entity
public class Person implements AccountAware {


    @OneToOne
    private EntityFile photo;
    @OneToOne
    private EntityFile cover;
    // other fields

    //getter and setters    
}

Beside entities, the UI module install a new Action called FileAction to manage files attached to entities. This action is showed in CrudState.READ (tables or tree) of CrudView.

The same functionality of FileAction can be using anywhere in your user interface code invoking

EntityFileUtils.showFileExplorer(entity);

EntityFileService

tools.dynamia.modules.entityfile.service.EntityFileService

This service is the central core of this module, it helps you to attach any kind of file to any JPA entity.

Examples:

//somewhere in your code
@Component
class SomeSpringCompoonent{

    @Autowired
    private EntityFileService service;

    public void attachPhoto(File file, Person entity) {
        var fileInfo = new UploadFileInfo(file);
        var photo = entityService.createEntityFile(fileInfo, entity);

        entity.setPhoto(photo);
    }
}

EntityFileStorage

Internally EntityFileService use an instance of tools.dynamia.modules.entityfile.EntityFileStorage to process and upload files.

• LocalEntityFileStorage is the default implementation and store files in local file system
• S3EntityFileStorage in module S3 can upload files to AWS S3 buckets
