基于用户角色的outputttext呈现条件

Question

我必须根据用户角色在JSF中呈现outputText输出文本框为:

<h:outputText id="citizenaddress" value="#{customerView.customerCurrentAddress}" escape="false" rendered="#{facesContext.externalContext.userInRole('isabletoGetCitizenAddress')}"></h:outputText>

web . xml是:

<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">

，例外是:

javax.el.ELException: /info/citizenInfo.xhtml @42,193 rendered="#{facesContext.externalContext.userInRole('isabletoGetCitizenAddress')}": Method userInRole not found

Answer 1

方法为isUserInRole(String)。

您可能将bean属性的表达式规则与方法的语法混淆了。

我认为表达式应该是:

#{facesContext.externalContext.isUserInRole('isabletoGetCitizenAddress')}

Answer 2

尝试将isabletoGetCitizenAddress的双引号改为单引号。<h:outputText id="citizenaddress" value="#{customerView.customerCurrentAddress}" escape="false" rendered="#{facesContext.externalContext.userInRole('isabletoGetCitizenAddress')}"></h:outputText>
