Java Load Properties 文件，定义message信息

初始化Properties对象，load properties文件：

private static final Properties MESSAGERESOURCES = new Properties();

static {
        try {
            MESSAGERESOURCES.load(ClassLoader.getSystemResourceAsStream("/messages.properties"));
            MessageFormat.format("", "");
        } catch (IOException e) {
            mylogger.error("Error >>>> : Could not load error message resource file 'message.properties'", e);
        }
    }

message.properties 文件内容：

ERROR_MESSAGE = test product number is {0}, the env {1} can not do this.

格式化message信息：

String para[] = {"1001", "dev_1"};

String message = MessageFormat.format(MESSAGERESOURCES.getProperty(“ERROR_MESSAGE”, para);

得到的Message信息为：

test product number is 1001, the env dev_1 can not do this.
