java - How to use dependency injection in JAXB unmarshalled objects? -

-

i have factory class

@applicationscoped /* 'applicationscoped' not must */ class myfactory {     @inject    private iservice aservice;     ... }

and jaxb annotated class

@xmlrootelement(name = "item") class anitem {    @inject   myfactory myfactory;    ... }

anitem instantiated jaxb xml file. problem myfactory null. if replace 

... myfactory myfactory = new myfactory(); ...

then myfactory.aservice null.

how can use dependency injection within classes created jaxb?

the following solution inspired block of adam warski, see beanmanager javadoc

at first i'll need 2 utility methods:

import javax.enterprise.inject.spi.bean; import javax.enterprise.inject.spi.beanmanager; import javax.naming.initialcontext; import javax.naming.namingexception;  public class utils {   public static beanmanager getbeanmanager() {     try {         initialcontext initialcontext = new initialcontext();         return (beanmanager) initialcontext.lookup("java:comp/beanmanager");     } catch (namingexception e) {         throw new runtimeexception("failed retrieve beanmanager!", e);     }   }    public static <t> t getbean(class<t> c) {     t result = null;     beanmanager bm = getbeanmanager();     set<bean<?>> beans = bm.getbeans(c);     if (! beans.isempty()) {         bean<?> bean = beans.iterator().next();         result = c.cast(bm.getreference(bean, c, bm.createcreationalcontext(bean)));     }     return result;   } }

class anitem has changed this:

@xmlrootelement(name = "item") class anitem {    myfactory myfactory = utils.getbean(myfactory.class);    ... }

hi project arc based, using uinavigationcontroller make transition between viewcontroller. using profiler analyse happening behind scene memory. noticed when push viewcontroller allocate memory components , when pop not freeing allocated memory. since using arc unable implement dealloc or release component. have analysed in detail , there no memory leak in project. i not using strong property push viewcontroller. here how pushing viewcontroller. viewcontroller *obj = [[viewcontroller alloc] init]; [self.navigationcontroller pushviewcontroller:obj animated:no]; any clue whats going on? should free memory have consumed. please advise your description indicates have retain cycle, leads objects not being deallocated. typical source of retain cycles properties assigned loading nib files (usually declared iboutlet ). two strategies break them , release objects: declare property weak : @property (nonatomic, weak) iboutlet uilabel *statuslabel; set property nil in...
