loginserviceimpl.java
@service public class loginserviceimpl implements loginservice{ @autowired tenantdao tenantdao; @transactional @override public string gettenantidentifier(string email, string password) { .... logincontroller.java
@component @scope("session") @qualifier("login") public class logincontroller { private string email; private string password; private string tenantid; @autowired loginservice loginservice; public void dologin() { this.tenantid = loginservice.gettenantidentifier(email, password); .. login.xhtml
<ui:define name="content"> <h:form id="form"> <p:growl id="growl" showdetail="true" life="3000" /> <h:panelgrid columns="2" cellpadding="5"> <h:outputlabel for="username" value="username:" /> <p:inputtext value="#{login.email}" id="username" required="true" label="username"/> <h:outputlabel for="password" value="password:" /> <p:inputtext value="#{login.password}" id="password" required="true" label="password" type="password" /> <f:facet name="footer"> <p:commandbutton id="loginbutton" value="login" update="growl" action="#{login.dologin()}"/> </f:facet> </h:panelgrid> </h:form> </ui:define> so choose use spring manage of beans. here's i've done resolve problem (but still no result)
i tried use inject jsf
@managedbeanlogincontroller, ,@managedpropertyloginservice. got null pointer after invokedologin(). said loginservice has null pointer.after tried use spring injection logincontroller can see above, got error.
/login.xhtml @21,109 value="#{login.email}": target unreachable, identifier 'login' resolved null
anyone can me ? follow , try many suggestion in forum, nothing's work.
finally figured out, need remove @qualifier annotation , edit @component annotation @component("login").
what silly mistakes...
