解决.properties文件中文读取乱码问题（idea Java）

一、 对于.properties文件的读取容易出现的中文读取乱码问题

1、原始代码 未加读取.properties文件的规则

public class CityCodeUtils {

    private static Properties properties = new Properties();
    public static String DEFAULT_CODE = "101010100";

    private CityCodeUtils() {

    }

    static  {
        ClassLoader classLoader = CityCodeUtils.class.getClassLoader();
        InputStream is = classLoader.getResourceAsStream("文件名.properties");
        try {
            properties.load(is);
        }  catch (IOException e) {
            throw new RuntimeException(e);
        }

    }

    public static String getCityCode(String cityName) {
        String code = properties.getProperty(cityName, "101010100");
        return code;
    }
}

2、加入.properties读取规则

public class CityCodeUtils {

    private static Properties properties = new Properties();
    public static String DEFAULT_CODE = "101010100";

    private CityCodeUtils() {

    }

    static  {
        ClassLoader classLoader = CityCodeUtils.class.getClassLoader();
        InputStream is = classLoader.getResourceAsStream("文件名.properties");
        try {

            //解决读取properties文件时的中文乱码问题
            //给中文读取设置为utf-8编码规则 若不加BufferedReader 设置的编码规则
            //则很有可能在读取文件名.properties 时出现乱码
            BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(is,"utf-8"));
            properties.load(bufferedReader);
        }  catch (IOException e) {
            throw new RuntimeException(e);
        }

    }
}

至此 问题已解决！
