### 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);
            }
    
        }
    }
