 	 * If specified will use the provided SpEL expression to resolve the security context. This
 	 * is convenient if users need to transform the result.
 	 *
-	 * <p>
-	 * For example, perhaps the user wants to resolve a CustomUser object that is final

-	 * that looks like:
-	 * </p>
-	 *
 	 * <pre>

-	 * }
+	 * &#64;CurrentSecurityContext(expression = "authentication") Authentication authentication
 	 * </pre>
 	 *
-	 * Then the user can specify an annotation that looks like:
+	 * <p>
+	 *    if you want to retrieve more object from the authentcation, you can see the following the expression
+	 * </p>

 	 * <pre>
