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

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;    }}

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！
