Spring boot 項目本地調試，因爲集成了OAuth2.每次調試都要在header裏面傳token.麻煩。如何跳過去呢。
在源代碼： AffirmativeBased.java 的第83行打一個斷點。執行到這裏的時候手動更改deny的值爲0.讓他不拋異常就好了。

改了這裏還不行，因爲後面有 checkAllowIfAllAbstainDecisions(); 需要在類AbstractAccessDecisionManager的第80行打一個斷點。手動改一下allowIfAllAbstainDecisions的值就好了。

這還不夠，還要在OAuth2SecurityExpressionMethods類的第70行打斷點。修改decision的值。讓其不拋異常。
/**
* Check if any scope decisions have been denied in the current context and throw an exception if so. This method
* automatically wraps any expressions when using {@link OAuth2MethodSecurityExpressionHandler} or
* {@link OAuth2WebSecurityExpressionHandler}.
*
* OAuth2Example usage:
*
* <pre>
* access = "#oauth2.hasScope('read') or (#oauth2.hasScope('other') and hasRole('ROLE_USER'))"
* </pre>
*
* Will automatically be wrapped to ensure that explicit errors are propagated rather than a generic error when
* returning false:
*
* <pre>
* access = "#oauth2.throwOnError(#oauth2.hasScope('read') or (#oauth2.hasScope('other') and hasRole('ROLE_USER'))"
* </pre>
*
* N.B. normally this method will be automatically wrapped around all your access expressions. You could use it
* explicitly to get more control, or if you have registered your own <code>ExpressionParser</code> you might need
* it.
*
* @param decision the existing access decision
* @return true if the OAuth2 token has one of these scopes
* @throws InsufficientScopeException if the scope is invalid and we the flag is set to throw the exception
*/
public boolean throwOnError(boolean decision) {
if (!decision && !missingScopes.isEmpty()) {
Throwable failure = new InsufficientScopeException("Insufficient scope for this resource", missingScopes);
throw new AccessDeniedException(failure.getMessage(), failure);
}
return decision;
}
重點:如何改值，在IDEA開發時，選中變量，鼠標右鍵選中 Evaluate Expression.然後在輸入框裏面賦值就好啦。
