websecurityconfig.java
@configuration @enablewebsecurity public class websecurityconfig extends websecurityconfigureradapter { @override protected void configure(authenticationmanagerbuilder auth) throws exception { auth. inmemoryauthentication() .withuser("user").password("user").roles("user").and() .withuser("admin").password("admin").roles("user", "admin"); } } securityapplicationinitializer.java

showcarlistaction
public class showcarlistaction implements action { /** list of cars. */ private list<car> carlist; /** auto service. */ private carservice carservice; @override public string execute() throws exception { carlist = carservice.loadallcars(); homecoming success; } public list<car> getcarlist() { homecoming carlist; } public void setcarservice(carservice carservice) { this.carservice = carservice; } }
i solve problem next steps:
switch annotation configuration spring beans (dont forget component-scan in spring xml) annotate websecurityconfig@component delete constructor in securityapplicationinitializer, because have contextconfiglocation java spring struts2 spring-security
