我已经将一个视图范围 bean 注入到另一个视图范围 bean 中，并且我可以访问第一个 bean 的一些属性，但其他属性在 @PostContruct 中显示为 null。我怎样才能看到它们的真正价值？

提前致谢

更新：我只能看到在第一个 bean 的 @PostContruct 中更新的属性值，而不是其他

Bean 1(SelectOfferMpans)

我已将一个请求范围 bean 注入另一个视图范围 bean

你不能将一个 bean 注入到另一个范围更广的 bean 中。

作为一项规则，以下可憎的行为是不允许的：）

  1. @RequestScoped>>@ViewScoped

  2. @ViewScoped>>@SessionScoped

  3. @SessionScoped>>@ApplicationScoped

编辑（根据您的更新）：注入 bean 的属性，而不是注入 bean 本身，将导致静态注入。静态注入意味着注入目标的值是注入时可用的值。作为执行以下行的时间：

@ManagedProperty(value="#{selectOfferMpans.selectedSites}")

selectedSites一片空白。所以你应该在那里做的是注入整个bean

@ManagedProperty(value="#{selectOfferMpans}")

这样，您就可以访问您感兴趣的任何变量的当前值
