JSF如何取得Request中的parameter
用户进入http://localhost:8080/test/active.jsf?username=xxx&activecode=yyy页面
?
?? active.jsp :
?
<h:form id="acctiveAccount_form"> <h:inputText id="username" value="#{accountActiveBean.username}" required="true" maxlength="30"/ > <h:inputText id="activecode" value="#{accountActiveBean.activecode}" required="true" maxlength="30"/ > <h:inputSecret id="password" value="#{accountActiveBean.password}" required="true" maxlength="20"/ > <h:commandButton id="submitButton" value="#{messages['button_submit']}" action="#{accountActiveBean.active}" /> </h:form> ?
如何让username和activecode得到url中的参数"xxx","yyy"?
?
1. #{param.xxx},#{param.xxx}
?
2. 可以使用这个方法获得?
????FacesContext.getCurrentInstance().getExternalContext()
??? .getRequestParameterMap().get("...");
