1.增加读取properties工具类

public class PropertiesListenerConfig {
        public static Map<String, String> propertiesMap = new HashMap<>();
    
        private static void processProperties(Properties props) throws BeansException {
            propertiesMap = new HashMap<String, String>();
            for (Object key : props.keySet()) {
                String keyStr = key.toString();
                try {
                    // PropertiesLoaderUtils的默认编码是ISO-8859-1,在这里转码一下
                    propertiesMap.put(keyStr, new String(props.getProperty(keyStr).getBytes("ISO-8859-1"), "utf-8"));
                } catch (UnsupportedEncodingException e) {
                    e.printStackTrace();
                } catch (java.lang.Exception e) {
                    e.printStackTrace();
                }
            }
        }
    
        public static void loadAllProperties(String propertyFileName) {
            try {
                Properties properties = PropertiesLoaderUtils.loadAllProperties(propertyFileName);
                processProperties(properties);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    
        public static String getProperty(String name) {
            return propertiesMap.get(name).toString();
        }
    
        public static Map<String, String> getAllProperty() {
            return propertiesMap;
        }
    }

2.在监听类中调用配置工具类

public void onApplicationEvent(ApplicationStartingEvent arg0) {
            PropertiesListenerConfig.loadAllProperties("platform-config.properties");
            System.out.println("sadasdasdasd"+PropertiesListenerConfig.propertiesMap.get("gps.gps-offset"));
    }
