推荐答案

您可以尝试使用<f:param>:

<ui:repeat value="#{userBean.users}" var="u">
    ...
    <h:link outcome="userDetails" value="Details">
        <f:param name="userID" value="#{u.id}" />
    </h:link>
    ...
</ui:repeat>

然后您将获得如下所示的ID:

then you can get the id like this:

@ManagedBean
@RequestScoped
public class UserDetailsBean {

    @ManagedProperty(value = "#{param.userID}")
    private String userID;

    // Getters and Setters
}
