Class CurrentSecurityContextArgumentResolver

java.lang.Object

org.springframework.security.web.method.annotation.CurrentSecurityContextArgumentResolver

All Implemented Interfaces:

org.springframework.web.method.support.HandlerMethodArgumentResolver

public final class CurrentSecurityContextArgumentResolver
extends java.lang.Object
implements org.springframework.web.method.support.HandlerMethodArgumentResolver

Allows resolving the SecurityContext using the CurrentSecurityContext annotation. For example, the following Controller:

 @Controller
 public class MyController {
     @RequestMapping("/im")
     public void security(@CurrentSecurityContext SecurityContext context) {
         // do something with context
     }
 }
 

it can also support the spring SPEL expression to get the value from SecurityContext

 @Controller
 public class MyController {
     @RequestMapping("/im")
     public void security(@CurrentSecurityContext(expression="authentication") Authentication authentication) {
         // do something with context
     }
 }
 

Will resolve the SecurityContext argument using SecurityContextHolder.getContext() from the SecurityContextHolder. If the SecurityContext is null, it will return null. If the types do not match, null will be returned unless CurrentSecurityContext.errorOnInvalidType() is true in which case a ClassCastException will be thrown.
