how to add filters to servlet when using @enablewebmvc annotation in spring 4? -

-

here current configuration

public class webappconfig implements webapplicationinitializer {     private static final string character_encoding_filter_encoding = "utf-8";     private static final string character_encoding_filter_name = "characterencoding";     private static final string character_encoding_filter_url_pattern = "/*";      private static final string dispatcher_servlet_name = "dispatcher";     private static final string dispatcher_servlet_mapping = "/";      @override     public void onstartup(servletcontext servletcontext) throws servletexception {         annotationconfigwebapplicationcontext rootcontext = new annotationconfigwebapplicationcontext();         rootcontext.register(exampleapplicationcontext.class);          configuredispatcherservlet(servletcontext, rootcontext);         enumset<dispatchertype> dispatchertypes = enumset.of(dispatchertype.request, dispatchertype.forward);         configurecharacterencodingfilter(servletcontext, dispatchertypes);         servletcontext.addlistener(new contextloaderlistener(rootcontext));     }      private void configuredispatcherservlet(servletcontext servletcontext, webapplicationcontext rootcontext) {         servletregistration.dynamic dispatcher = servletcontext.addservlet(                 dispatcher_servlet_name,                 new dispatcherservlet(rootcontext)         );         dispatcher.setloadonstartup(1);         dispatcher.addmapping(dispatcher_servlet_mapping);     }      private void configurecharacterencodingfilter(servletcontext servletcontext, enumset<dispatchertype> dispatchertypes) {         characterencodingfilter characterencodingfilter = new characterencodingfilter();         characterencodingfilter.setencoding(character_encoding_filter_encoding);         characterencodingfilter.setforceencoding(true);         filterregistration.dynamic characterencoding = servletcontext.addfilter(character_encoding_filter_name, characterencodingfilter);         characterencoding.addmappingforurlpatterns(dispatchertypes, true, character_encoding_filter_url_pattern);     } }

now want use @enablewebmvc

@enablewebmvc @componentscan(basepackages = { "com.example.mvc.base.controller" }) public class webappconfig extends webmvcconfigureradapter { }

how add filters , listeners servletcontext did using webapplicationinitializer?

  1. you still continue adding filters , listeners thorough webapplicationinitializer. class methods starts web application servlet registered required contexts , beans.
  2. in class dispatcherservlet created containing programmatically configured annotationconfigwebapplicationcontext.the dispatcher mapped .html. 
  3. webappconfig class enables webmvc based on annotation , scans base packages annotated resources. these further registered web application context of default servlet initialized webapplicationinitializer.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
