java.util.MissingResourceException: Can't find bundle for base name xxx.package.messages

Caused by: java.util.MissingResourceException: Can’t find bundle for base name xxx.package.messages

问题描述

在使用ResourceBundle处理国际化properties文件时

private static final ResourceBundle RESOURCE_BUNDLE 
					= ResourceBundle.getBundle(BUNDLE_NAME);

结果：

Caused by: java.util.MissingResourceException: 
Can't find bundle for base name xxx.package.messages, locale zh_CN
	at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1573)
	at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1396)
	at java.util.ResourceBundle.getBundle(ResourceBundle.java:782)

解决方案

如要读取message.properties文件

不带包名

将message.properties文件放在src/main/resources下，那么

private static final String BUNDLE_NAME = "message";

带包名

如果将message.properties放在在src/main/resources某个包下，如com.example，那么：

private static final String BUNDLE_NAME = "com/example/message";

如果还是报同样的错，请检查target目录下message.properties是否真正放置正确！！

工具类

附上用ResourceBundle获取message.properties文件的工具类:

public abstract class Messages {

	//注意！！ 不用带properties后缀
	//直接将message.properties放在resources/com/exmple/下
	private static final String BUNDLE_NAME = "com/example/message";
	
	//直接将message.properties放在resources下
	//private static final String BUNDLE_NAME = "message";

	private static final ResourceBundle RESOURCE_BUNDLE = ResourceBundle.getBundle(BUNDLE_NAME);


	public static String getString(String key){
		try {
			return RESOURCE_BUNDLE.getString(key);
		} catch (MissingResourceException e) {
			return '!' + key + '!';
		}
	}

	public static String getString(String key, Object ...args){
		try {
			return MessageFormat.format(RESOURCE_BUNDLE.getString(key), args);
		} catch (MissingResourceException e) {
			return '!' + key + '!';
		}
	}
}

good luck !
