java - Spring MVC & Freemarker session attribute not exposed -

i've got problem freemarker's viewresolver spring - session attributes not exposed view, in spring's internalresourceviewresolver.

now, important part is: when change spring's resolver freemarker's one, session attribute not passed, it's null. when spring's resolver working, session passed.

my code:

dispatcher-servlet.xml:

logincontroller.java:

@controller @requestmapping("/login") @sessionattributes("usersession") public class logincontroller {      @autowired     private usersdatabaseservice usersdatabaseservice;      @requestmapping(method = requestmethod.post)     public string login(             @modelattribute userlogincredentials userlogincredentials,             usersession usersession,             final redirectattributes redirectattributes)     {         int failedloginattempts = usersession.getfailedloginattempts();          if (failedloginattempts < loginconfig.maxlogintries ||                 system.currenttimemillis()-usersession.getfailedloginswaittimestart() > loginconfig.failedloginswaitminutes*60*1000) {              if (usersdatabaseservice.isvalidpassword(userlogincredentials.getusername(), userlogincredentials.getpassword())) {                 usersession.setuser(usersdatabaseservice.getuser(userlogincredentials.getusername()));                     usersession.setfailedloginswaittimestart(system.currenttimemillis());             }             else {                 failedloginattempts++;                  if (failedloginattempts == loginconfig.maxlogintries) {                     redirectattributes.addflashattribute("error",                              "you've entered invalid username or password more "                             + loginconfig.maxlogintries + " times. try again in "                             + loginconfig.failedloginswaitminutes +" minutes.");                 }                 else {                      redirectattributes.addflashattribute("error", "invalid username or password");                     usersession.setfailedloginattempts(failedloginattempts);                     system.out.println(failedloginattempts);                 }             }         }         else {             redirectattributes.addflashattribute("error",                      "you've entered invalid username or password more "                     + loginconfig.maxlogintries + " times. try again in "                     + loginconfig.failedloginswaitminutes +" minutes.");          }          return "redirect:/";     } } 

indexcontroller:

@controller @requestmapping("/index") public class indexcontroller {     @requestmapping(method=requestmethod.get)     public string getindex(model model) {         return "index";     }      @modelattribute("userregistercredentials")     public userregistercredentials getuserregistercredentials() {         return new userregistercredentials();     }      @modelattribute("userlogincredentials")     public userlogincredentials getuserlogincredentials() {         return new userlogincredentials();     } } 

index.jsp:

<body>     <!-- code freemarker -->     <#if error??>         ${error}     </#if>      <#if usersession??>         ${usersession}     </#if>      <#if !(usersession??)>         b     </#if>      <!-- code jstl -->     ${usersession} 

you have session problem because of redirectattributes.addflashattribute(). means addflashattribute stores attributes in flashmap (which internally maintained in users session , removed once next redirected request gets fulfilled),

just try without redirectattributes.addflashattribute() session.

may you
