如何在后备bean中以字符串形式获取message.properties的条目? [英] How can I get an entry of message.properties as a String in backing bean?

问题描述

我需要在后备bean中将message.properties的消息作为String接收.

I need to get message.properties's message as a String in backing bean.

我该如何实现?

推荐答案

如果将其定义为faces-config.xml中application的message-bundle，如下所示

If it is definied as a message-bundle of the application in faces-config.xml like follows

<application>
    <message-bundle>messages</message-bundle>
</application>

然后您可以通过 Application#getMessageBundle()

then you can get its name by Application#getMessageBundle()

String messageBundleName = facesContext.getApplication().getMessageBundle();

通过这种方式，您可以获取其 ResourceBundle 实例如下:

This way you can get its ResourceBundle instance as follows:

ResourceBundle messageBundle = ResourceBundle.getBundle(messageBundleName);

最后，您可以按如下所示通过键获取message属性:

Finally you can get a message property by key as follows:

String value = messageBundle.getString("property.key");
