Nutch的插件机制分析

Abstract

Abstract: The design principles of Nutch's plug-in mechanism are discussed.Nutch's lightweight plug-in architecture includes three basic concepts.They are micro-kernel,extension point and extension;plug-in,plug-in manifest and plug-in manifest descriptor;plug-in factory and plug-in manifest parser.The processes of plug-in and the mappings between relative concepts and real files in Nutch are also summarized.It's obvious that in-depth understanding of Nutch's plug-in mechanism can contribute to build flexible new applications based on Nutch.

Key words: Nutch, micro-kernel, plug-in, extension, extension point
