CAS Logout 通知全部登陸客戶端銷燬Session

具體通知由org.jasig.cas.authentication.principal.AbstractWebApplicationService發出。logOutOfService方法生成發送消息，而後由org.jasig.cas.util.HttpClient的sendMessageToEndPoint方法發出。
public boolean sendMessageToEndPoint(final String url, final String message) {
HttpURLConnection connection = null;
BufferedReader in = null;
try {
if (log.isDebugEnabled()) {
log.debug("Attempting to access " + url);
}
final URL logoutUrl = new URL(url);
final String output = "logoutRequest=" + URLEncoder.encode(message, "UTF-8");

connection = (HttpURLConnection) logoutUrl.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setReadTimeout(this.readTimeout);
connection.setConnectTimeout(this.connectionTimeout);
connection.setRequestProperty("Content-Length", ""
+ Integer.toString(output.getBytes().length));
connection.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
final DataOutputStream printout = new DataOutputStream(connection
.getOutputStream());
printout.writeBytes(output);
printout.flush();
printout.close();

in = new BufferedReader(new InputStreamReader(connection
.getInputStream()));

while (in.readLine() != null) {
// nothing to do
}

if (log.isDebugEnabled()) {
log.debug("Finished sending message to" + url);
}
return true;
} catch (final Exception e) {
log.error(e,e);
return false;
} finally {
if (in != null) {
try {
in.close();
} catch (final IOException e) {
// can't do anything
}
}
if (connection != null) {
connection.disconnect();
}
}
}

CAS4.2單點登陸如何配置多個系統登陸一次和退出到登陸頁問題 200

一、我用CAS4.2搭建了cas服務端，客戶端是3.4.1版本二、如今服務端配置好了，也能夠經過我配置的客戶端系統訪問和查詢數據庫登陸三、問題：我配置了兩個cas系統castest1和castest2，兩個系統serverName分別配置爲hhaip-cas1.com和hhaip-cas2.com，如今我訪問castest1且登陸成功，而後同一瀏覽器訪問castest2仍是跳轉到登陸頁面，預期應該直接跳轉到我訪問的頁面纔是四、問題2：我想退出到登陸頁，可是我每次都退出到我設置的那個連接，且打開瀏覽器新標籤訪問我這個系統居然不會跳轉到登陸頁而是直接跳轉到個人系統頁面，即：我可能沒有退出成功，下圖是個人退出URL和客戶端web.xml配置。五、注意個人cas-server是4.2版本和老版本差異很大，請你們不要複製其餘的代碼回答問題。

最佳答案

 

對於cas4.0在cas-server.xml中搜索logoutAction,將${cas.logout.followServiceRedirects:false}中的false改爲true,以下:<bean id="logoutAction" class="org.jasig.cas.web.flow.LogoutAction"p:servicesManager-ref="servicesManager"p:followServiceRedirects="${cas.logout.followServiceRedirects:true}"/>至於cas4.2,cas-server.xml中少了不少東西,把這三行放到最後試試
