我有一个带有注销按钮的应用程序。双击按钮后,我得到一个ViewExpiredException
:
An unexpected exception was caught during processing the request:
javax.faces.application.ViewExpiredException: /faces/session-timeout.xhtml
我的注销方法具有以下结构:
try {
destroyBackendSession(); // this logs to be successful
} catch (InvalidArgumentException e) {
logError(e);
} finally {
try {
FacesContext.getCurrentInstance().getExternalContext().redirect(userBean.getPortalUrl());
} catch (IOException e) {
logError(e);
}
FacesContext.getCurrentInstance().getExternalContext().invalidateSession();
}
此处未记录任何错误,因此似乎所有内容都按预期工作。
bean是请求作用域。
我web.xml
的潜在相关配置:
<context-param>
<!-- Serialization and deserialization of the component tree is a major performance hit. -->
<param-name>org.apache.myfaces.SERIALIZE_STATE_IN_SESSION</param-name>
<param-value>false</param-value>
</context-param>
[...]
<error-page>
<exception-type>javax.faces.application.ViewExpiredException</exception-type>
<location>/faces/session-timeout.xhtml</location>
</error-page>
理想情况下,我想在注销后将用户重定向到门户页面,而不是错误页面。 (参见logout() - 上面的方法中的userBean.getPortalUrl()
)
