前言
修改properties文件的目录：在application.yml或者application.properties中配置 spring.message.basename
spring:
application:
name: test-worklog
messages:
basename: i18n/messages
encoding: UTF-8
MessageSource的使用：
1. 无参数
operation.success = 操作成功。
String msg1 = this.messageSource.getMessage(" operation.success ", null, Locale.CHINA);
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;
}
总结
