java - unable to use matrix variable in spring -

i learning springmvc , encountered problem not able use matrix variables when call url neither hitting controller nor showing exception not triggering code expected have following classes:

controller class

@autowired     productrepositiry productrepositiry;  @requestmapping("/filter/{path}")     public string getfiltered(@matrixvariable(pathvar = "path") map<string, list<string>> filterparms, model model) {         model.addattribute("items", productrepositiry.getfilteredproducts(filterparms));          return "viewall";     } 

repositiry class

private list<item> list = new arraylist<>();      public list<item> getlist() {          item first = new item();         first.setitemone("firstone");         first.setitemtwo("firsttwo");         first.setitemthree("firstthree");          item second = new item();          second.setitemone("seconeone");         second.setitemtwo("firsttwo");         second.setitemthree("secondthree");          item third = new item();         third.setitemone("thirdone");         third.setitemtwo("thirdtwo");         third.setitemthree("thirdthree");          item 4 = new item();         four.setitemone("fourone");         four.setitemtwo("fourtwo");         four.setitemthree("thirdthree");          list.add(first);         list.add(second);         list.add(third);         list.add(four);         return list;     }      public set<item> getfilteredproducts(map<string, list<string>> filterparms) {         set<string> keys = filterparms.keyset();         set<item> itemone = new hashset<>();         set<item> itemtwo = new hashset<>();          if (keys.contains("item")) {             (string 1 : filterparms.get("item")) {                 (item : list) {                     if (one.equalsignorecase(i.getitemtwo()))                         itemone.add(i);                 }             }         } else             throw new nullpointerexception("value not found");         if (keys.contains("one")) {             (string 2 : filterparms.get("one")) {                 (item : list) {                     if (two.equalsignorecase(i.getitemthree())) {                         itemtwo.add(i);                     }                 }             }         }          itemone.addall(itemtwo);         (item : itemone) {             system.out.println(i.getitemone());         }         return itemone;     } } 

url

http://localhost:8080/matrix_variables/filter;item=firsttwo

while hitting url viewall (jsp page) supposed show data of first , second repositiry class returning error

error

http status 404 -  type status report  message  description requested resource not available.  apache tomcat/8.0.36 

the thing mention when i'm running project ("/") working fine when introduced matrix variable not working.

and dispatcherservlet-servlet.xml

<mvc:annotation-driven enable-matrix-variables="true" />     <context:component-scan base-package="com" />     <bean         class="org.springframework.web.servlet.view.internalresourceviewresolver">         <property name="suffix" value=".jsp" />         <property name="prefix" value="/view/" />     </bean> 

all want fetch values repositiry using matrix variable view not happening,i wrong there, not able find it,can me problem.

best regards

you using ";" in request url. use "/" instead.
