场景: 项目中常常会有一些message , 如邮件, 短信, UI的提示信息, 多数情况,写在代码中,或者配置文件xxx.properties, @value 或者读取xxx.properties ,这两种方案都...
1.好处,统一管理
2.动态管理,如配置了appolo , 配置中心
3. 配置国际化, 如中文 ,英文
使用:
一.依赖:
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-validation</artifactId> </dependency>
二.配置文件xxx.properties位置:
默认名字为 messages.properties
内容 :eg
//event.validation.content= Notification {0} exception was detected, caused by : {1} Sincerely XXX Team //event.validation.subject=ERROR: Validation error found for booking <{0}>
三.配置类:
import lombok.extern.slf4j.Slf4j; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.MessageSource; import org.springframework.stereotype.Component; import java.util.Locale; @Component @Slf4j public class MesgHelper { private static MessageSource messageSource; public static MessageSource getMessageSource() { return messageSource; } @Autowired public void setMessageSource(MessageSource msgSource) { MesgHelper.messageSource = msgSource; } /** * Convert single message according to locale. * * @param mesgKey * @param values * @param locale * @return */ public static String getMessage(String mesgKey,Object[] values,Locale locale) { Locale locale1 = locale!=null?locale:Locale.US; String mesgText = null; if(mesgKey != null && locale1 != null) { mesgText = messageSource.getMessage(mesgKey, values, locale1); } return mesgText; } }
四.使用:
//注入 @Autowired MesgHelper mesgHelper private static Runnable validationNotify(String bookingNo,String mesgKeys,String body) { return ()->{ log.debug("Current thread is {}",Thread.currentThread()); log.info("@@!!@@ NOT pass the null validation checking , below data not allow null: {}", mesgKeys); LinkedHashMap msgBody = JSONObject.parseObject(body,new TypeReference<LinkedHashMap<String, Object>>(){} ,Feature.OrderedField); String mailBody = JSONObject.toJSONString(msgBody, SerializerFeature.PrettyFormat, SerializerFeature.WriteMapNullValue); //参数变量 用{0} {2} 表示 //event.validation.content= Notification {0} exception was detected, caused by : {1} Sincerely XXX Team //event.validation.subject=ERROR: Validation error found for booking <{0}> //参数变量 Object[] paras = {bookingNo}; String subject = mesgHelper.getMessage("event.validation.subject", paras, null); //参数变量 Object[] params = { mesgKeys, mailBody}; String content = mesgHelper.getMessage("event.validation.content", params, null); MailUtils.sendMail(auoExOp,from,subject,content,to); }; }
