SpringBoot攔截全域性異常併發送郵件給指定郵箱
阿新 • • 發佈:2019-01-07
主要是看一下Springboot中傳送郵件的方法,至於攔截Springboot全域性異常之前的文章中有。
一 傳送郵件
在Springboot中傳送郵件非常簡單。
pom.xml引入maven依賴
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
在application.yml裡設定發信人的賬號、密碼spring:
mail:
host: smtp.qq.com
username: [email protected]
password: njcvcbdkrofgbhie
properties:
mail:
smtp:
auth: true
starttls:
enable: true
required: true
這個username就是未來發信時的郵箱地址,password是授權碼。這裡以普通qq郵箱為例,注意password不是qq密碼,而是授權碼。
在qq郵箱-設定-賬戶,找到圖片中的地方,開啟IMAP/SMTP服務,開啟後才能在別的客戶端使用該qq郵箱發郵件,然後生成授權碼,填寫到application.yml的password位置。
然後就可以使用該郵箱作為發件人了。
看一下發郵件的具體程式碼,參考http://blog.csdn.net/clementad/article/details/51833416
然後就可以使用裡面的方法發郵件了。package com.tianyalei.testmail.service; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.beans.factory.annotation.Value; import org.springframework.core.io.FileSystemResource; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSender; import org.springframework.mail.javamail.MimeMessageHelper; import org.springframework.stereotype.Service; import javax.mail.MessagingException; import javax.mail.internet.MimeMessage; import java.io.File; @Service public class MailService { private final Logger logger = LoggerFactory.getLogger(this.getClass()); @Autowired private JavaMailSender sender; @Value("${spring.mail.username}") private String from; /** * 傳送純文字的簡單郵件 * @param to * @param subject * @param content */ public void sendSimpleMail(String to, String subject, String content){ SimpleMailMessage message = new SimpleMailMessage(); message.setFrom(from); message.setTo(to); message.setSubject(subject); message.setText(content); try { sender.send(message); logger.info("簡單郵件已經發送。"); } catch (Exception e) { logger.error("傳送簡單郵件時發生異常!", e); } } /** * 傳送html格式的郵件 * @param to * @param subject * @param content */ public void sendHtmlMail(String to, String subject, String content){ MimeMessage message = sender.createMimeMessage(); try { //true表示需要建立一個multipart message MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(content, true); sender.send(message); logger.info("html郵件已經發送。"); } catch (MessagingException e) { logger.error("傳送html郵件時發生異常!", e); } } /** * 傳送帶附件的郵件 * @param to * @param subject * @param content * @param filePath */ public void sendAttachmentsMail(String to, String subject, String content, String filePath){ MimeMessage message = sender.createMimeMessage(); try { //true表示需要建立一個multipart message MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(content, true); FileSystemResource file = new FileSystemResource(new File(filePath)); String fileName = filePath.substring(filePath.lastIndexOf(File.separator)); helper.addAttachment(fileName, file); sender.send(message); logger.info("帶附件的郵件已經發送。"); } catch (MessagingException e) { logger.error("傳送帶附件的郵件時發生異常!", e); } } /** * 傳送嵌入靜態資源(一般是圖片)的郵件 * @param to * @param subject * @param content 郵件內容,需要包括一個靜態資源的id,比如:<img src=\"cid:rscId01\" > * @param rscPath 靜態資源路徑和檔名 * @param rscId 靜態資源id */ public void sendInlineResourceMail(String to, String subject, String content, String rscPath, String rscId){ MimeMessage message = sender.createMimeMessage(); try { //true表示需要建立一個multipart message MimeMessageHelper helper = new MimeMessageHelper(message, true); helper.setFrom(from); helper.setTo(to); helper.setSubject(subject); helper.setText(content, true); FileSystemResource res = new FileSystemResource(new File(rscPath)); helper.addInline(rscId, res); sender.send(message); logger.info("嵌入靜態資源的郵件已經發送。"); } catch (MessagingException e) { logger.error("傳送嵌入靜態資源的郵件時發生異常!", e); } } }
可以先寫個簡單的測試類,呼叫
mailService.sendSimpleMail("[email protected]", "主題:簡單郵件", "測試郵件內容");
填寫個收信人的地址就OK了。然後就能收到郵件了。收信人可以有多個,通過SimpleMailMessage可以看到。二 攔截全域性異常併發郵件
定義一個全域性攔截類package com.tianyalei.testmail.global;
import com.tianyalei.testmail.service.MailService;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.context.request.WebRequest;
import org.springframework.web.servlet.mvc.method.annotation.ResponseEntityExceptionHandler;
import javax.servlet.http.HttpServletRequest;
import java.io.PrintWriter;
import java.io.StringWriter;
import java.util.Enumeration;
import static org.springframework.http.HttpStatus.NOT_EXTENDED;
/**
* Created by wuwf on 17/3/31.
* 全域性異常處理
*/
@ControllerAdvice
public class GlobalExceptionHandler extends ResponseEntityExceptionHandler {
private Logger logger = LoggerFactory.getLogger(getClass().getName());
@Autowired
private MailService mailService;
/**
* 在controller裡面內容執行之前,校驗一些引數不匹配啊,Get post方法不對啊之類的
*/
@Override
protected ResponseEntity<Object> handleExceptionInternal(Exception ex, Object body, HttpHeaders headers, HttpStatus status, WebRequest request) {
System.out.println("錯誤");
return new ResponseEntity<>("出錯了", NOT_EXTENDED);
}
@ExceptionHandler(value = Exception.class)
@ResponseBody
public String jsonHandler(HttpServletRequest request, Exception e) throws Exception {
log(e, request);
StringWriter sw = new StringWriter();
PrintWriter pw = new PrintWriter(sw);
e.printStackTrace(pw);
//傳送郵件
mailService.sendSimpleMail("[email protected]", "異常", sw.toString());
return "發生異常";
}
private void log(Exception ex, HttpServletRequest request) {
logger.error("************************異常開始*******************************");
logger.error("請求地址:" + request.getRequestURL());
Enumeration enumeration = request.getParameterNames();
logger.error("請求引數");
while (enumeration.hasMoreElements()) {
String name = enumeration.nextElement().toString();
logger.error(name + "---" + request.getParameter(name));
}
StackTraceElement[] error = ex.getStackTrace();
for (StackTraceElement stackTraceElement : error) {
logger.error(stackTraceElement.toString());
}
logger.error("************************異常結束*******************************");
}
}
當有異常時會進入被@ExceptionHandler標註的方法中,在該方法裡做異常日誌的記錄和發郵件的邏輯。手動觸發個異常,看看結果可以看到已經收到郵件了。
