java - Spring 4 + Tiles (3 || 2.2.2) - Any way to access beans in view context? -

i trying access beans in tiles view.

tried solutions:

solution 1 tried

the solution accessing spring beans tiles view (jsp) francarl posted (servletcontextattributeexporter) working fine on first view (hello.jsp, not theme.jsp).

<?xml version="1.0" encoding="iso-8859-1" ?> <!doctype tiles-definitions public         "-//apache software foundation//dtd tiles configuration 3.0//en"         "http://tiles.apache.org/dtds/tiles-config_2_0.dtd"> <tiles-definitions>     <definition name="defaulttheme" template="/web-inf/views/theme.jsp" /> </tiles-definitions> 

i can access bean in hello.jsp not in /web-inf/views/theme.jsp

solution 2 tried

tried skaffman solution, 'tilesexposingbeansviewresolver', executing , buildview , it's code view.setexposecontextbeansasattributes(this.exposecontextbeansasattributes); executed too. rendermergedoutputmodel view class not executed. tried lot of way doing this. (tried these orders -1, 1, 10, 100, 99999). don't sure whatever can access these beans @ theme.jsp work. (i don't know why 1 doesn't fire up)

solution 3 tried

tried create viewpreparer, execute working , springbeanautowiringsupport.processinjectionbasedoncurrentcontext(this); sucessfully injects bean viewpreparer. unabled transfer viewpreparer theme , hello.jsp

public class viewpiewpreparer implements viewpreparer {      @autowired     private mainbean kmpv;      public void execute(tilesrequestcontext tilesrequest, attributecontext attributecontext)             throws preparerexception {         springbeanautowiringsupport.processinjectionbasedoncurrentcontext(this);          system.out.println(kmpv.gettwits().size()); // working          // cant access of these in hello , template         tilesrequest.getrequestscope().put("deneme", "deneme");         tilesrequest.getsessionscope().put("deneme", "deneme");         tilesrequest.getapplicationcontext().getapplicationscope().put("deneme", "deneme")      } }

is there solution this? need access news , tweets theme.jsp.

public class mainbean {      @autowired     kamptanimfacade kamptanimfacade;      @autowired     kategorifacade kategorifacade;      public list<kategori> getkamplar() {         return kategorifacade.getmenulist();     }      public list<status> gettwits() {         return mainservlet.twitter.statuses;     }      public string getdeneme() {         return "deneme";     } } 

if set tilesconfigurer resolve preparers bean names:

@bean public tilesconfigurer gettilesconfigurer() {     tilesconfigurer configurer = new tilesconfigurer();     configurer.setdefinitions(new string[] { "/web-inf/tiles.xml" });     ...     configurer.setpreparerfactoryclass(springbeanpreparerfactory.class);     return configurer; } 

and configure tiles definition use specific view preparer (spring bean name) in tiles.xml:

<definition name="viewname" template="/web-inf/.../view.jsp" preparer="aviewpreparer">     <put-attribute .... /> </definition> 

you can define bean (inside @componentscan) like:

@component public class aviewpreparer implements viewpreparer {      @autowired     private autowiredbean autowiredbean;      @override     public void execute(request tilesrequest,          attributecontext attributecontext) throws preparerexception {         attributecontext.putattribute("tilesattributename",              new attribute("tilesattributevalue"));     } } 

this way can print attribute (string) using in jsp:

<tiles:insertattribute name="tilesattributename"/> 

if need use complex object attribute, bean or list, can use following in jsp:

<tiles:importattribute name="tilesattributename"/> 

and then, have object in page scope , can work (in case of list):

<c:foreach items="${tilesattributename}" var="item">     ${item} </c:foreach> 

you can use simplespringpreparerfactory instead of springbeanpreparerfactory in tilesconfigurer, in case should use complete class name of view preparer in tiles.xml:

<definition name="viewname" template="/web-inf/.../view.jsp" preparer="package.name.of.view.preparer.aviewpreparer">     <put-attribute .... /> </definition>
