在java中,在多语言国际化时可以用 *.java 类来作为资源文件使用。
1. 首先定义类, 类必须继承ListResourceBundle
类所在路径为: src/I18N
1 public class myMessage_en_US extends ListResourceBundle { 2 3 private final Object mydata[][] = { { "hello", "hello!" }, 4 { "greetting", "Love you . {0}" } }; 5 6 @Override 7 protected Object[][] getContents() { 8 return mydata; 9 } 10 11 }
2. 编写测试用例,使用资源文件
该文件在default package 包里面
public static void main() { Locale current = new Locale("zh","CN"); ResourceBundle bundle = ResourceBundle.getBundle("myMessage", current); String format = bundle.getString("greetting"); System.out.println(MessageFormat.format(format, "Jay")); }
可惜的是出错了
Exception in thread "main" java.util.MissingResourceException: Can‘t find bundle for base name myMessage, locale zh_CN at java.util.ResourceBundle.throwMissingResourceException(Unknown Source) at java.util.ResourceBundle.getBundleImpl(Unknown Source) at java.util.ResourceBundle.getBundle(Unknown Source) at program.I18NTest(program.java:89) at program.main(program.java:20)
尝试很多次之后还是不好使,最终把类 myMessage_en_US和调用的main函数都放在了default package下面。好使了
输出结果
你好,Jay
看来是资源路径的问题,经过各种尝试之后把路径进行了修改,如下
private static void I18NTest() { Locale current = new Locale("zh","CN"); ResourceBundle bundle = ResourceBundle.getBundle("I18N.myMessage", current); String format = bundle.getString("greetting"); System.out.println(MessageFormat.format(format, "Jay")); }
而不是修改文件存放的路径。
Java: MissingResourceException, "Can't find bundle for base name myMessage, locale zh_CN"
