我遇到了Spring Security的麻煩。我可以登錄但不能登出（至少不是如預期的那樣）。春季安全註銷
登錄後，我將被重定向到/secure/home.xhtml < - 此工作正常，並按預期工作。但是我無法通過＃{request.contextPath} /註銷註銷。 （我已經改變了春季安全配置註銷URL，但我也有一個默認試過）總有一個404
這裏至今代碼：
index.xhtm < - 工作正常
<form method="POST" id="loginForm" action="#{request.contextPath}/j_spring_security_check" class="form-signin" autocomplete="off">
<div class="form-group">
<label for="username" class="control-label">#{bundle["login.username"]}</label>
<input type="text" name="username" id="username" class="input-block-level form-control"
placeholder="#{bundle['label.username']}" required="true" tabindex="1" />
<span class="help-block"></span>
</div>
<div class="form-group">
<label for="password" class="control-label">#{bundle["login.password"]}</label>
<input type="password" class="input-block-level form-control" name="password" id="password" tabindex="2"
placeholder="#{bundle['label.password']}" required="true" />
<span class="help-block"></span>
</div>
<button type="submit" tabindex="3" class="btn btn-success btn-block">#{bundle["login.action"]}</button>
<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" />
</form>
彈簧security.xhtml，HTTP的conf
<security:http use-expressions="true" >
<security:intercept-url pattern="/secure/**" access="hasAnyRole('USER','ADMIN')" />
<security:intercept-url pattern="/admin/**" access="hasRole('ADMIN')" />
<!--<security:access-denied-handler error-page="/404.xhtml" />-->
<security:form-login
login-page="/index.xhtml"
default-target-url="/secure/home.xhtml"
authentication-failure-url="/index.xhtml?error"
username-parameter="username"
password-parameter="password" />
<security:logout logout-url="/logout" logout-success-url="/index.xhtml?logout" invalidate-session="true" delete-cookies="JSESSIONID" />
<security:csrf />
</security:http>
這是我試圖執行關於向其他的答案在這裏STA註銷的方式ckoverflow：
<a href="#{request.contextPath}/logout">logout</a>
<h:outputLink value="#{request.contextPath}/logout">Logout</h:outputLink>
但這兩個鏈接都不起作用。我得到了404.我也讀過你應該用pageContext.request.contextPath替換request.contextPath，但那也不行。 （以代替localhost：8080/myContext /註銷鏈接將我重定向到本地主機：8080 /註銷）
一個教程給我看，說註銷可以用這個來還實施：
<form method="POST" id="loginForm" action="#{request.contextPath}/logout" class="form-signin" autocomplete="off">
<button type="submit" tabindex="3" class="btn btn-success btn-block">#{bundle["logout.action"]}</button>
<input type="hidden" name="#{_csrf.parameterName}" value="#{_csrf.token}" />
</form>
在開始它似乎解決了我的問題，但在向安全部分添加更多頁面（例如「profile.xhtml」）之後，我加入了在加載頁面後註銷的不受歡迎的行爲。 因此，如果我在我的home.xhtml中添加上面的註銷表單，即使我沒有點擊註銷，似乎也會註銷。如果我刷新頁面，即使沒有點擊註銷，我也會被重定向到index.xhtml（登錄）。所以，如果我點擊鏈接到profile.xhtml，我會自然重定向到index.xhtml，因爲春天認爲我退出了。沒有這個表單，我保持登錄狀態，但無法註銷！一團糟！
啊，如果我在註銷按鈕單擊窗體上，我得到以下錯誤：
HTTP Status 403 - Expected CSRF token not found. Has your session expired?
type Status report
messageExpected CSRF token not found. Has your session expired?
descriptionAccess to the specified resource has been forbidden.
我也實在沒有想法什麼毛病我的配置:(

使用的GlassFish 4.1，Spring Framework的版本4.1.2.RELEASE和春季安全版本3.2.5.RELEASE
我希望每一個答案。這個錯誤已經花了兩天，沒有任何解決方案:(
