我是新來的春天3.2.2。我試圖在運行時使用Spring提供的工具ReloadableResourceBundleMessageSource重新加載資源包。但它似乎不能按預期工作。我已經創建了以下獨立的Java應用程序示例。春季問題ReloadableResourceBundleMessageSource
請查找下面的應用程序上下文xml文件和示例的源代碼。

/**

public class TestSpringInterLocalization {
/**

public static void main(String[] args) throws Exception{
// TODO Auto-generated method stub
ApplicationContext ctx=new ClassPathXmlApplicationContext("com/springinterlocalization/springinternationalizationcontext.xml");
System.out.println(ctx.getMessage("jinesh.thirdtest", null, null));
System.out.println("Updating the properties file");
FileOutputStream fos = null;
try {
fos = new FileOutputStream("C:\\workspace\\SpringExamples\\src\\standard.properties");
fos.write("jinesh.latestaddproperty=this is the newly added property."
.getBytes("UTF-8"));
fos.close();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("going to sleep for 10 secs while the bundles are reloaded");
Thread.sleep(10 * 1000);
System.out.println(ctx.getMessage("jinesh.latestaddproperty", null, null));
}
}
在上述例子中我試圖添加jinesh.latestaddproperty到屬性文件在類路徑standard.properties文件,但它似乎屬性被添加到屬性文件,但彈簧不能夠接受這種變化並給出下面的錯誤。

我只想知道爲什麼spring不能挑選變化以及如何解決問題?
你的答案,但由於春季是六必居不能從文件中的絕對路徑讀爲好。我在該文件(jinesh.propeties)中添加了簡單屬性,但spring無法從該文件讀取任何屬性。任何想法 ? – Beast
我認爲絕對文件的問題是不需要指定擴展名,所以只需要指定basename爲'file:/D:/Jinesh/jinesh'而不是'file:/D:/Jinesh/jinesh.properties'。另外,我在本地嘗試了類似的設置,並且我看到了房地產的變化。 –
即使刪除.properties擴展名,我仍然面臨同樣的問題。我無法讀取文件文件中指定的任何屬性:/ D:/ Jinesh/jinesh。你有什麼想法爲什麼這是行不通的? – Beast
