Class BasicLogEventEntity

java.lang.Object

org.apache.logging.log4j.core.appender.db.jpa.AbstractLogEventWrapperEntity

org.apache.logging.log4j.core.appender.db.jpa.BasicLogEventEntity

All Implemented Interfaces:

Serializable, LogEvent

@MappedSuperclass
public abstract class BasicLogEventEntity
extends AbstractLogEventWrapperEntity

Users of the JPA appender may want to extend this class instead of AbstractLogEventWrapperEntity. This class implements all of the required mutator methods but does not implement a mutable entity ID property. In order to create an entity based on this class, you need only create two constructors matching this class's constructors, annotate the class @Entity and @Table, and implement the fully mutable entity ID property annotated with @Id and @GeneratedValue to tell the JPA provider how to calculate an ID for new events.

The attributes in this entity use the default column names (which, according to the JPA spec, are the property names minus the "get" and "set" from the accessors/mutators). If you want to use different column names for one or more columns, override the necessary accessor methods defined in this class with the same annotations plus the @Column annotation to specify the column name.

The getContextMap() and getContextStack() attributes in this entity use the ContextMapAttributeConverter and ContextStackAttributeConverter, respectively. These convert the properties to simple strings that cannot be converted back to the properties. If you wish to instead convert these to a reversible JSON string, override these attributes with the same annotations but use the ContextMapJsonAttributeConverter and ContextStackJsonAttributeConverter instead.

All other attributes in this entity use reversible converters that can be used for both persistence and retrieval. If there are any attributes you do not want persistent, you should override their accessor methods and annotate with @Transient.

Constructor Detail

BasicLogEventEntity

public BasicLogEventEntity()

Instantiates this base class. All concrete implementations must have a constructor matching this constructor's signature. The no-argument constructor is required for a standards-compliant JPA provider to accept this as an entity.

BasicLogEventEntity

public BasicLogEventEntity(LogEvent wrappedEvent)

Instantiates this base class. All concrete implementations must have a constructor matching this constructor's signature. This constructor is used for wrapping this entity around a logged event.

Parameters:

wrappedEvent - The underlying event from which information is obtained.

getLevel

public org.apache.logging.log4j.Level getLevel()

Gets the level. Annotated with @Basic and @Enumerated(EnumType.STRING).

Returns:

the level.

getLoggerName

public String getLoggerName()
