Chapter 2. Mapping Entities - 0 views

  • Composite identifier
  • You can define a composite primary key through several syntaxes:
  • @EmbeddedId
  • ...66 more annotations...
  • map multiple properties as @Id properties
  • annotated the property as
  • map multiple properties as @Id properties and declare an external class to be the identifier type
  • declared on the entity via the @IdClass annotation
  • The identifier type must contain the same properties as the identifier properties of the entity: each property name must be the same, its type must be the same as well if the entity property is of a
  • basic type
  • last case is far from obvious
  • recommend you not to use it (for simplicity sake)
  • @EmbeddedId property
  • @EmbeddedId
  • @Embeddable
  • @EmbeddedId
  • @Embeddable
  • @Embeddable
  • @EmbeddedId
  • Multiple @Id properties
  • arguably more natural, approach
  • place @Id on multiple properties of my entity
  • only supported by Hibernate
  • does not require an extra embeddable component.
  • @IdClass
  • @IdClass on an entity points to the class (component) representing the identifier of the class
  • WarningThis approach is inherited from the EJB 2 days and we recommend against its use. But, after all it's your application and Hibernate supports it.
  • Mapping entity associations/relationships
  • One-to-one
  • three cases for one-to-one associations:
  • associated entities share the same primary keys values
  • foreign key is held by one of the entities (note that this FK column in the database should be constrained unique to simulate one-to-one multiplicity)
  • association table is used to store the link between the 2 entities (a unique constraint has to be defined on each fk to ensure the one to one multiplicity)
  • @PrimaryKeyJoinColumn
  • shared primary keys:
  • explicit foreign key column:
  • @JoinColumn(name="passport_fk")
  • foreign key column named passport_fk in the Customer table
  • may be bidirectional
  • owner is responsible for the association column(s) update
  • In a bidirectional relationship, one of the sides (and only one) has to be the owner
  • To declare a side as
  • not responsible for the relationship
  • the attribute
  • mappedBy
  • is used
  • mappedBy
  •  Indexed collections (List, Map)
  • Lists can be mapped in two different ways:
  • as ordered lists
  • as indexed lists
  • @OrderBy("number")
  • List<Order>
  • List<Order>
  • List<Order> 
  • To use one of the target entity property as a key of the map, use
  • @MapKey(name="myProperty")
  •  @MapKey(name"number")
  • Map<String,Order>
  • String number

      map key used in Customer.orders
  • @MapKeyJoinColumn/@MapKeyJoinColumns
  • if the map key type is another entity
  • @ManyToAny
  • 2.4.5.2. @Any
  • @Any annotation defines a polymorphic association to classes from multiple tables
  • this is most certainly not meant as the usual way of mapping (polymorphic) associations.
  • @ManyToAny allows polymorphic associations to classes from multiple tables
  • first column holds the type of the associated entity
  • remaining columns hold the identifier
  • not meant as the usual way of mapping (polymorphic) associations

Not able to set global mime-mapping | JBoss AS 7 | JBoss Community - 1 views

  • Not able to set global mime-mapping
  • mime-mapping is complex field and not resource. that is why it has its own operation handlers add-mime/remove-mime to handle its value. what are you trying to achive can be done by command:
  • /subsystem=web/configuration=container:add-mime(name=manifest,value="text/cache-manifest")
  • ...1 more annotation...
  • Just bit of a warning when using this, there was a bug in 7.1.1 when you added mime type that prevented server to start.so please use 7.1.2 or 7.2 nightly builds where this is fixed.

Logback-beagle - 0 views

  • Logback-beagle: an Eclipse plug-in for viewing logs
  • Logback-beagle is intended as a replacement for viewing logs via the console. It offers several advantages over the plain-old console: Events of level WARN and ERROR are marked by an orange flag and respectively a red flag. Quickly jump to the class and line where a given logging request originated Easly view and jump to the callers of any log statement upto eight levels deep Change the output format on-the-fly Measure the time elapsed between any two lines of log
