jsf 中的动态绑定
我在 JSF 页面中遇到动态绑定问题 我正在使用 JSF 1.1
我想要的只是管理器具有动态的管理器名称
<%String manger="ManagerName";%>
上面的代码只是一个片段，它将作为
jsf 文件中的请求参数代码
<h:inputText id="street1" value="#{address.street1}"
binding = "#{<%=manager%>.billingStreet}"
/>
出现这是错误我正在得到的

您不能混合使用 scriptlet
<% %>和 EL${ }。使用其中之一。由于它来自请求参数，因此只需在 EL 中将其作为
${param.name}访问即可。如果 bean 在请求范围内，那么您可以通过${requestScope[param.name]}访问它。因此：对于会话作用域 bean，请使用
#{sessionScope}代替。与问题无关，这种设计/方法有味道。
You can't mix scriptlets
<% %>and EL${ }. Use the one or the other.Since it comes from a request parameter, just access it as
${param.name}in EL. If the bean is in the request scope, then you can then access it by${requestScope[param.name]}. So:For a session scoped bean, use
#{sessionScope}instead.Unrelated to the problem/question, this design/approach smells.
