07.03 架構實戰篇（十三）：Spring Boot Logback 郵件通知

日誌對於應用程序來說是非常重要的，當你的程序報錯了，而你又不知道是多麼可怕的一件事情，本文使用logback把程序報錯信息郵件到開發者

目錄結構

項目依賴配置

pom.xml

這裡主要使用了spring boot 郵件的依賴 spring-boot-starter-mail , 確實好方便

日誌郵件配置

mail-appender.xml


<included>
 
 <property>
 <property>
 <property>
 <property>
 <property>
 <property>
 <property>
 <property>
 <appender>
 <smtphost>${smtpHost}/<smtphost>
 <smtpport>${smtpPort}/<smtpport>
 <username>${username}/<username>
 <password>${password}/<password>
 ${SSL}
 <asynchronoussending>false/<asynchronoussending>
 ${mailTo} 
 <from>${mailFrom}/<from>
 <subject>${mailSubject}/<subject>
 <layout>
 <filter>
 <level>ERROR/<level>
 /<filter>
 /<appender>
/<included>
 <property>
 <property>
 <property>
 <property>

這裡需要把你自己的郵箱配置上去，並填上你的授權密碼

郵箱記得打開 smtp 設置

Logback 配置

logback.xml


<configuration>
 
 <include>
 
 <property>
 
 <include>
  

 <include>
 
 <include>
 <root>
 <appender-ref>
 <appender-ref>
 <appender-ref>
 /<root>
/<configuration>

這裡導入郵件配置文件和增加一行

日誌文件配置

application.properties

logging.path=../logs
logging.file=../logs/file.log
logging.level.root=info
spring.http.encoding.charset=utf-8

模擬異常

AppController

package com.itunion.log.mail;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import java.util.Random;
@RequestMapping("/app")
@RestController
public class AppController {
 private Logger logger = LoggerFactory.getLogger(AppController.class);
 @RequestMapping
 public String selectList() {
 boolean flag = new Random().nextBoolean();
 if (flag) { 

 throw new RuntimeException("查詢報錯");
 } else {
 return "正常返回 當前時間：" + System.currentTimeMillis();
 }
 }
 @ExceptionHandler
 @ResponseBody
 public String exceptionHandler(Exception e) {
 logger.error(e.getMessage(), e);
 return e.getMessage();
 }
}
