Next, we need to analyze the WMS project.

The package of the geoserver WMS project is as follows:

Org. geoserver. wms	Contains the webmapservice interface for responding to WMS requests, defaultwebmapservice by default, wmsinfo for service configuration, WMS loading, and watermarks. The defaultwebmapservice class forwards getmap and other operations to specific Bean components for operations, such as wmsgetmap.
Org. geoserver. wms. kvp	Name-Value Pair (kVp)-related parsing class
Org. geoserver. wms. responses	The WMS output is enhanced, such as the pluile output.
Org. geoserver. wms. responses. decoration	Add decoration, such as scale and watermark to WMS output.
Org. geoserver. wms. util	Contains WMS helper classes. Currently, only wmsrequests classes that help construct WMS requests are included.
Org. geoserver. wms. xml	Currently, only the class sldxmlrequestreader that reads the SLD request XML is included.
Org. vfny. geoserver. config	Configuration model. The main class is wmsconfig.
Org. vfny. geoserver. global	Saves the application information. There is only one WMS class, which has beenOrg. geoserver. wmsReplace the wmsinfo interface.
Org. vfny. geoserver. sld	Currently, only the SLD exception class sldexception is included.
Org. vfny. geoserver. sld. requests	Class for reading SLD requests in WMS
Org. vfny. geoserver. sld. responses	Class for responding to SLD in WMS
Org. vfny. geoserver. wms	Contains the response interfaces for some WMS operations, the most important of which is the getmapproducer interface, which is implemented by map in various formats, including abstractgetmapproducer, abstractrastermapproducer, atomgeorssmapproducer ultrastermapproducer, geotiffmapproducer, gifmapproducer, extends mapproducer, kmlmapproducer, kmzmapproducer, metatilemapproducer, openlayersmapproducer, pngmapproducer, rssgeorssmapproducer, svgmapproducerproxy, tiffmapproducer, etc.
Org. vfny. geoserver. wms. requests	The class that reads WMS requests.
Org. vfny. geoserver. WMS. Requests. Readers	Contains the wmsxmlrequestreader class.
Org. vfny. geoserver. WMS. Responses	The packet that responds to WMS, including the map generation class in various formats.
Org. vfny. geoserver. WMS. Responses. featureinfo
Org. vfny. geoserver. WMS. Responses. helpers	Includes some tool classes for responding to WMS, such as describelayertransformer, jaisupport, and wmscapstransformer.
Org.vfny.geoserver.wms.responses.legend.gif	Generation and conversion of legends containing GIF format
Org. vfny. geoserver. WMS. Responses. Legend. Jai	Generation and conversion of legends that contain formats supported by the Jai Library

Org. vfny. geoserver. WMS. Responses. Legend. Raster
Org. vfny. geoserver. WMS. Responses. Map. georss	Contains the map SS format map generation and conversion classes, such as atomgeorssmapproducer and rssgeorssmapproducer.
Org. vfny. geoserver. WMS. Responses. Map. geotiff	Mapmapproducer
Org.vfny.geoserver.wms.responses.map.gif	Generate and convert a map in GIF format
Org.vfny.geoserver.wms.responses.map.jpeg	Generate and convert a map in JPEG format
Org. vfny. geoserver. WMS. Responses. Map. kml	Generate and convert map containing kml format
Org. vfny. geoserver. WMS. Responses. Map. metatile	Generate and convert map in tile form
Org. vfny. geoserver. WMS. Responses. Map. openlayers	Generate and convert a Map in the form of Openlayers
