如何使用Weld注入不可序列化的类（如java.util.ResourceBundle）

问题描述

我想创建一个Producer，它可以将java.util.ResourceBundle注入任何类，以便轻松获取本地化的字符串。我的ResourceBundle-Producer如下所示：

I want to create a Producer that makes it possible to inject a java.util.ResourceBundle into any class in order to get localized Strings easily. My ResourceBundle-Producer looks like this:

public class ResourceBundleProducer {
  @Inject       
  public Locale locale;

  @Inject       
  public FacesContext facesContext;

  @Produces
  public ResourceBundle getResourceBundle() {
    return ResourceBundle.getBundle("/messages", locale )
  }
}

Locale和FacesContext的注入工作（从Seam 3 Alpha Source获取相应的生产者）。但不幸的是，ResourceBundle不是Serializable，因此无法以这种方式生成。当我试图访问一个调用使用我的ResourceBundle的bean的JSF页面时，我从Weld得到以下错误：

The Injection of Locale and FacesContext works (took the corresponding producers from the Seam 3 Alpha Source). But unfortunately, ResourceBundle is not Serializable and therefore can't be produced in this way. I'm getting the following Error from Weld when trying to access a JSF-page which calls a bean that uses my ResourceBundle:


引起的：org.jboss.weld.IllegalProductException：WELD-000054生产者不能产生用于注射不可序列实例为钝化beans\\\\

Producer\的非瞬态字段：org.jboss.weld .bean- / d：/ Program Files文件（x86）的/GlassFish-Tools-Bundle-For-Eclipse-1.2/glassfishv3/glassfish/domains/teachernews/applications/teachernews/-ProducerMethod-services.producers.ResourceBundleProducer.getResourceBundle（）\\ \\
Injection Point \：field web.PersonH​​ome.bundle


有没有办法让我的ResourceBundleResolver工作？或者是否有其他机制来获得类似的功能？
提前致谢！

Are there any ways to get my ResourceBundleResolver to work? Or are there any other mechanisms to get a similar functionality?Thanks in advance!

编辑：

好的，我我会花掉一些难得的积分;）
也会接受这个问题的好方法！

Okay, i'll spent some of my hardly earned points ;)Will also accept a good workaround for this issue!

我有另一个例子，创建一个制作人没有'工作：FlashProducer。还无法生成FacesContext-Flash，因为Flash不可序列化。

I got another example where creating a Producer doesn't work: a FlashProducer. A FacesContext-Flash also cannot be produced because Flash isn't serializable.

推荐答案

首先，ResourceBundle 不可序列化。请参见。消息很明确

Well, First of all ResourceBundle is not Serializable. See here. And The message is clear

钝化豆 ???我认为 web.PersonH​​ome 是有状态会话Bean或@ConversationScoped bean。我对吗 ？？？如果是这样，你应将你的捆绑属性标记为瞬态

passivating beans ??? I Think web.PersonHome is Either a Stateful Session Bean or a @ConversationScoped bean. Am i right ??? If so you should mark your bundle property as transient

private transient @Inject ResourceBundle bundle;
