我可以动态加载资源包吗?我可以动态编辑资源包吗?

Can I load a resource bundle dynamically? Can I edit a resource bundle dynamically?

如果我能拥有这样一个逻辑资源包(即位于上下文中而不是物理文件)，那将是最好的.

It would be best if I can have such a logical resource bundle (i.e. located in context not as physical file).

如何从文件加载资源包资源?

推荐答案

你能覆盖 ListResourceBundle?它提供了一个扩展点，用于添加您自己的 Object[][] 资源密钥对.

Would you be able to override the ListResourceBundle? It provides an extension point for adding in your own Object[][] of resource key pairs.

来自 javadoc:

From the javadoc:

public class MyResources extends ListResourceBundle {
     protected Object[][] getContents() {
         return new Object[][] = {
         // LOCALIZE THIS
             {"s1", "The disk "{1}" contains {0}."},  // MessageFormat pattern
             {"s2", "1"},                               // location of {0} in pattern
             {"s3", "My Disk"},                         // sample disk name
             {"s4", "no files"},                        // first ChoiceFormat choice
             {"s5", "one file"},                        // second ChoiceFormat choice
             {"s6", "{0,number} files"},                // third ChoiceFormat choice
             {"s7", "3 Mar 96"},                        // sample date
             {"s8", new Dimension(1,5)}                 // real object, not just string
         // END OF MATERIAL TO LOCALIZE
         };
     }
 }

此示例返回一个硬编码列表，但您可以修改它以从数据库或其他任何内容中返回您想要的任何内容.

This example returns a hard coded listing but you can modify that to return whatever you want from a database or anything else.
