The best practice of the%Bundlename framework in the Java class library
In Java development, we often need to perform localized processing so that the text resources of applications or libraries can be translated into different languages.The %Bundleename framework is a common mechanism to deal with localized resources in Java. It provides a convenient way to load localized resource files and apply it to the application.
The %Bundleename framework usually uses .properties files to store text resources in different languages, and read and loaded through Java code.Below is the best practice of the%Bundleename framework:
1. Use naming agreement: When using the%Bundleename framework, it is recommended to use a specific naming agreement to organize resource files.Generally, the resource files of each language should have the same basic name as the original resource files and end the language identifier.For example, for a resource file called "MESSAGES.PROPERTIES", its French translation version should be named "MESSAGES_FR.PROPERTIES".
2. Place resource files: It is recommended to place all resource files under the class path of the application. The files under the same directory structure should maintain the same package hierarchical structure.This can easily find and load resource files by the%Bundleename framework.
3. Use attribute file encoding: Make sure that all resource files are saved with correct character codes in order to correctly read and process the text.UTF-8 coding is usually recommended.
4. Load resource file: When using the%Bundleename framework to load resource files in the Java code, usually create a ResourceBundle object, and specify the basic name and Locale of the resource file to be loaded.For example, for a resource file called "MESSAS.PROPERTIES", you can use the following code to load:
import java.util.ResourceBundle;
import java.util.Locale;
ResourceBundle bundle = ResourceBundle.getBundle("messages", Locale.getDefault());
In the above example, Locale.getDefault () returns the default Locale of the current system.If you need to load the resource files of a specific language version, you can pass the corresponding Locale parameters, such as Locale.french to load the French version of resource files.
5. Obtain resource value: Once the resource file is loaded, you can obtain the resource value corresponding to the specific key through the GetString () method of the ResourceBundle object.For example, if you want to obtain a string corresponding to the "Hello" key, you can use the following code:
String helloMessage = bundle.getString("hello");
System.out.println(helloMessage);
The above code will print the string value corresponding to the "Hello" key in the resource file.
The %Bundleename framework provides a convenient way to handle localized resources in the Java library.By following the best practice above, you can easily use the%Bundlename framework to manage text resources and provide correct translation for different languages.
