我正在使用Spring Security SAML 1.0.1。我有set up the IDP metadata so it reaches a Discovery service，它由idpDiscoveryURL定義。該參數包含URL http://wayf-shib.ueb.eu/fede-renater/WAYF。SAML遠程發現服務：缺少「返回」參數
已到達遠程發現，但它抱怨該請求不包含「返回」參數。事實上，這是Spring SAML生成請求：
http://wayf-shib.ueb.eu/fede-renater/WAYF?entityID=http%3A%2F%2Facem.u-bretagneloire.fr%3A80%2FACEM%2Fsaml%2Fmetadata&returnIDParam=idp
所生成的參數是：
entityID與正確值;returnIDParam由值爲「idp」的值由Spring SAML自動設置。
問題：如何配置Spring Security SAML，使其產生的請求return參數？
如果這能幫助，這是我目前的配置：
