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();
}
这里没有记录错误,所以这里似乎一切都按预期工作。
bean 是请求范围的。
我的潜在相关配置web.xml
:
<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userBean.getPortalUrl()
上面的 logout() 方法)
