spring boot国际化——MessageSource的使用

spring:
    application:
        name: test-worklog
    messages:
        basename: i18n/messages
        encoding: UTF-8

operation.success = 操作成功。

2. 动态参数

start.ge.end = 开始日期{0}必须小于结束日期{1}！

String [] param = {startDate, endDate};

String msg =getMessage("start.ge.end", param);

@Autowired
private MessageSource messageSource;

/**
 * 国际化
 *
 * @param result
 * @return
 */
public String getMessage(String result, Object[] params) {
    String message = "";
    try {
        Locale locale = LocaleContextHolder.getLocale();
        message = messageSource.getMessage(result, params, locale);
    } catch (Exception e) {
        LOGGER.error("parse message error! ", e);
    }
    return message;
}

补充一个方法，适用于类中无法获取到MessageSource

/**
 * 国际化
 * 注：通过@Autowired private MessageSource messageSource无法获取
 *
 * @param result
 * @return
 */
public String getMessage(String result, Object[] params) {
    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setCacheSeconds(-1);
    messageSource.setDefaultEncoding(StandardCharsets.UTF_8.name());
    messageSource.setBasenames("/i18n/messages");

    String message = "";
    try {
        Locale locale = LocaleContextHolder.getLocale();
        message = messageSource.getMessage(result, params, locale);
    } catch (Exception e) {
        log.error("parse message error! ", e);
    }
    return message;
}
