spring mvc - Tuckey URL Rewrite Filter Java Class Configuration -

i have been researching how perform url rewrites on tomcat 8 , keep running same 2 suggestions.

1) use tuckey urlrewritefilter. 2) run apache on top of tomcat use mod_rewrite.

in regards former, urlrewritefilter doesn't appear have documentation how configure in java format opposed xml. spring mvc application not make use of web.xml file - configuration done via java classes - , i'm not in position configure xml.

is there way configure in way or there alternatives other trying run apache on top of tomcat?

for example, there way achieve in java opposed xml:

<filter>    <filter-name>urlrewritefilter</filter-name>    <filter-class>org.tuckey.web.filters.urlrewrite.urlrewritefilter</filter-class> </filter> <filter-mapping>     <filter-name>urlrewritefilter</filter-name>     <url-pattern>/*</url-pattern>     <dispatcher>request</dispatcher>     <dispatcher>forward</dispatcher> </filter-mapping> 

this webapplicationinitializer class:

public class initializer implements webapplicationinitializer {  @override public void onstartup(servletcontext container) {   // create 'root' spring application context   annotationconfigwebapplicationcontext rootcontext =     new annotationconfigwebapplicationcontext();   rootcontext.register(rootconfig.class);    // manage lifecycle of root application context   container.addlistener(new contextloaderlistener(rootcontext));    // create dispatcher servlet's spring application context   annotationconfigwebapplicationcontext dispatchercontext =     new annotationconfigwebapplicationcontext();   dispatchercontext.register(webappconfig.class);    // register , map dispatcher servlet   servletregistration.dynamic dispatcher =     container.addservlet("dispatcher", new dispatcherservlet(dispatchercontext));   dispatcher.setloadonstartup(1);   dispatcher.addmapping("/*");   dispatcher.addmapping("*.html"); }   } 

my rootconfig

@configuration @componentscan(basepackages={"com.ucrisko.*"},     excludefilters={       @componentscan.filter(type=filtertype.annotation, value=enablewebmvc.class)     }) public class rootconfig {  } 

and webappconfig

@configuration @enablewebmvc @componentscan(basepackages={"com.ucrisko.*"}) public class webappconfig extends webmvcconfigureradapter{  @override public void addresourcehandlers(resourcehandlerregistry registry) {     registry.addresourcehandler("/resources/**").addresourcelocations("/resources/"); }  ...various other beans } 

in spring boot can define filter bean in configuration. i'm not sure if works in plain spring mvc can try. 1 awkward thing configuring filter java code - have implement filterconfig. working spring boot example looks (snippet config class):

@bean public urlrewritefilter urlrewritefilter(final servletcontext servletcontext) throws servletexception {     urlrewritefilter urlrewritefilter = new urlrewritefilter();     urlrewritefilter.init(new filterconfig() {         private final map<string, string> params = new hashmap<string, string>();         {             params.put("confpath", "urlrewrite.xml");         }          @override         public string getfiltername() {             return "urlreritefilter";         }          @override         public servletcontext getservletcontext() {             return servletcontext;         }          @override         public string getinitparameter(string name) {             return params.get(name);         }          @override         public enumeration<string> getinitparameternames() {             return collections.enumeration(params.keyset());         }     });      return urlrewritefilter; } 

as regular spring mvc, seems should implement webapplicationinitializer. webapplicationinitializer java code equivalent of web.xml configuration. according documentation, spring should pick implementations classpath , run them. sample implementation may (note: haven't tested if works, should set on right path):

public class initalizer extends abstractannotationconfigdispatcherservletinitializer {      @override     protected class<?>[] getrootconfigclasses() {         return null;     }      @override     protected class<?>[] getservletconfigclasses() {         return new class<?>[] {webappconfig.class};     }      @override     protected string[] getservletmappings() {         return new string[] {"/*", "*.html"};     }      @override     protected filter[] getservletfilters() {         urlrewritefilter urlrewritefilter = new urlrewritefilter();         /*          * add filter configuration here if necessary          */         return new filter[] {urlrewritefilter};     } } 

abstractannotationconfigdispatcherservletinitializer spring's implementation of webapplicationinitializer interface intention make initialization of dispcherservlet (which entry point spring mvc) easier. in example webappconfig.class main spring java config class.

edit

if prefer keep current initializer code, should posssible add following lines in onstartup method:

filterregistration.dynamic urlrewritefilter = servletcontext.addfilter("urlrewritefilter",  new urlrewritefilter()); urlrewritefilter.setinitparameter("confpath", "urlrewrite.xml"); urlrewritefilter.addmappingforurlpatterns(enumset.of(dispatchertype.request, dispatchertype.forward), false, "/*");
