Nick Williams commented on LOG4J2-229: -------------------------------------- Ralph fixed this with r1482707. > New JDBC, JPA, and NoSQL database Appenders > ------------------------------------------- > > Key: LOG4J2-229 > URL: https://issues.apache.org/jira/browse/LOG4J2-229 > Project: Log4j 2 > Issue Type: New Feature > Components: Appenders, Core > Affects Versions: 2.0-beta5 > Reporter: Nick Williams > Assignee: Nick Williams > Attachments: db-appenders-r1479389.patch > > Original Estimate: 168h > Remaining Estimate: 168h > > As discussed on the mailing list ([1] and [2]), Log4j 2 is in need of some > database appenders. I have added this new feature and will attach a patch > shortly. The patch contains: > - A slight change to PatternLayout. Currently it is not possible to create a > PatternLayout that doesn't always handle exceptions. If you leave all > exception handling out of the pattern, an exception handler is forcibly added > to the end of the pattern. This behavior is controlled by a flag, but that > flag is always hard-coded to false. I added a parameter for it. This was > necessary for the JDBC appender. > - o.a.l.l.core.appender.db.AbstractDatabaseManager and > AbstractDatabaseAppender, together in concert, take care of some core > functionality common across all database appenders, such as buffering and > connection state. > - o.a.l.l.core.appender.db.jdbc.JDBCAppender (and Manager, other classes) > supports writing events to a relational database using raw JDBC. It's > injection-safe due to the use of prepared statements. It can be configured > with URL/username/password, JNDI data source, or a connection factory method. > - o.a.l.l.core.appender.db.jpa.JPAAppender (and Manager, other classes) > supports writing events to a relational database using the Java Persistence > API version 2.0. > - o.a.l.l.core.appender.db.nosql.NoSQLAppender (and Manager, other classes) > supports writing to an abstract concept of a NoSQL provider. Providers have > been created for MongoDB and Apache CouchDB. Creating a new provider is > extremely easy. > - Thorough unit tests for the abstract classes, the JDBC and JPA appenders, > and the abstract parts of the NoSQLAppender. Directly unit testing the > MongoDB and CouchDB providers in a platform-independent way is not easy and > may not be possible. > - Thorough documentation (both JavaDoc and Site documentation) for all of the > appenders. > [1] http://markmail.org/thread/z2wpmwelv7p6xh2o > [2] http://markmail.org/thread/s7pljqdjhjz5xfk5 -- This message is automatically generated by JIRA.
