java - 缺少资源异常 : Can't find bundle for base name

Question

我知道在 stackoverflow 和其他论坛上有很多关于此错误的问题和答案。但我仍然找不到解决方案...

我的代码:

package com.sodifrance.apex.presentation.generic.utils;

import java.util.ResourceBundle;

public class EnumTranslator {

    private static EnumTranslator instance = null;

    private EnumTranslator() {
    }

    public static EnumTranslator getDefaut() {
        if (instance == null)
        {
            instance = new EnumTranslator();
        }
        return instance;
    }

    public String translate(Enum<?> enumerationValue) {
        String localizedMessage = "";

        if (enumerationValue != null)
        {
            ResourceBundle b = ResourceBundle.getBundle("resources.enumerations");

            localizedMessage = enumerationValue.name();

            if (b != null)
            {
                localizedMessage = b.getString(enumerationValue.getDeclaringClass().getName() + "." + enumerationValue.name());
            }
        }

        return localizedMessage;
    }
}

Tomcat 控制台:

当我在 Debug模式下检查这一行时:

ResourceBundle b = ResourceBundle.getBundle("resources.enumerations");

我有这样的消息:

The method getBundle(String) is undefined for the type Enum Translator

我的文件配置:

Resource.getBundle 采用 FQCN 作为参数。在语句 ResourceBundle.getBundle("resources.enumerations") 中，JRE 正在查找文件 resources/enumerations<_local>.properties

在您的示例中，您应该使用 getBundle("com.sod.ap.properties.enumerations")
