最近公司接了宜家的幾個產品，需要在原有的抽取服務添加完成後郵寄通知功能。先搞個初級版本，話不多說，上代碼：
一，引入依賴包
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-email</artifactId>
<version>1.5</version>
</dependency>
二，配置相關信息
email:
yijia: ## 開發環境
host: smtp.163.com
charset: gbk
username: 郵箱@163.com
password: EPXXX
templateName: yiJiaEmail
subject: IKEA related code table update tips
receiveMails: 接收[email protected],接收[email protected]
如果本地測試用自己郵件，需要開下權限。
三，郵件模板
在resources下創建templates文件夾寫需要的模板，eg：
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<style type="text/css">
body{
margin: 0px;
}
table.imagetable {
font-size:18px;
border-width: 1px;
border-collapse: collapse;
margin: auto;
}
table.imagetable th {
width: 350px;
border-width: 1px;
padding: 15px;
border-style: solid;
border-color: #CDC1C5;
}
table.imagetable td {
/*background:#dcddc0;*/
border-width: 1px;
padding: 15px;
border-style: solid;
border-color: #CDC1C5;
width: 350px;
text-align: center;
}
.daastitle{
/*display: inline-block;*/
padding: 6px 15px;
margin-bottom: 0;
font-size: 23px;
font-weight: normal;
line-height: 1.42857143;
text-align: center;
white-space: nowrap;
vertical-align: middle;
background-image: none;
border: 1px solid transparent;
border-radius: 4px;
color: #fff;
background-color: #5bc0de;
border-color: #46b8da;
}
</style>
<head>
<meta charset="UTF-8"/>
</head>
<body>
<div style="width: 700px;margin: auto;margin-top:50px">
<div class="daastitle"> 抽取任務完成</div>
<table class="imagetable">
<tr style="background-color: #fff">
<td>任務名稱</td>
<td>產品編號</td>
</tr>
<tr style="background-color: #fff">
<td th:text="${taskName}"></td>
<td th:text="${productKey}"></td>
</tr>
</table>
</div>
</body>
</html>
四，工具類
package com.easipass.extract.util;
import java.util.HashMap;
import java.util.Map;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.mail.EmailException;
import org.apache.commons.mail.HtmlEmail;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.thymeleaf.TemplateEngine;
import org.thymeleaf.context.Context;
/**

*/
@Configuration
@Slf4j
public class EmailTool {
private static TemplateEngine templateEngine;
@Autowired
public EmailTool(TemplateEngine templateEngine) {
EmailTool.templateEngine = templateEngine;
}
// 1 字符串 2 html
public static Map<String, Object> sendEmail(
Map<String, Object> datamap, Map<String, Object> emailParam, String type)
throws EmailException {
Map<String, Object> resultMap = new HashMap();
int successSum = 0;
int errSum = 0;
StringBuffer errEmails = new StringBuffer();
String templateName = (String) emailParam.get("templateName");
String[] receiveMails = (String[]) emailParam.get("receiveMails");
String subject = (String) emailParam.get("subject");
String context = null;
if ("1".equals(type)) {
context = (String) datamap.get("context");
} else if ("2".equals(type)) {
context = getContext(datamap, templateName);
} else {
log.error("##### 不支持此類型郵件 #####");
}
for (String email : receiveMails) {
try {
sendEmail(email, context, subject, emailParam);
log.info("發送郵件 至: " + email + " 成功");
successSum++;
} catch (Exception e) {
log.info("發送郵件 至: " + email + " 失敗,異常信息：" + e.getMessage(), e);
errSum++;
errEmails.append(email + ",");
}
}
resultMap.put("successSum", successSum);
resultMap.put("errSum", errSum);
if (errSum > 0) {
resultMap.put("errEmails", errEmails.deleteCharAt(errEmails.length() - 1).toString());
}
return resultMap;
}
private static void sendEmail(
String mailto, String context, String subject, Map<String, Object> emailParam)
throws EmailException {
String host = (String) emailParam.get("host");
String charset = (String) emailParam.get("charset");
String username = (String) emailParam.get("username");
String password = (String) emailParam.get("password");
HtmlEmail email = new HtmlEmail();
email.setHostName(host);
email.setCharset(charset);
email.setAuthentication(username, password);
email.setFrom(username, "");
email.setSubject(subject);
email.setHtmlMsg(context);
email.addTo(mailto);
String send = email.send();
log.info("send = " + send);
}
// 獲取html模板
private static String getContext(Map<String, Object> datamap, String templateName) {
Context context = new Context();
context.setVariables(datamap);
return templateEngine.process(templateName, context);
}
}
五，使用
private Map<String, Object> sendEmail(TaskInfoDTO taskInfo) throws Exception {
Map<String, Object> datamap = new HashMap<>();
String context = null;
// ...
// context 發送內容
// ...
datamap.put("context", context);
Map<String, Object> emailParam = new HashMap<>();
emailParam.put("host", host);
emailParam.put("charset", charset);
emailParam.put("username", username);
emailParam.put("password", password);
emailParam.put("templateName", templateName);
emailParam.put("subject", subject);
emailParam.put("receiveMails", receiveMails);
return EmailTool.sendEmail(datamap, emailParam, "1");
}
六，效果圖
郵件模板寫的很簡單，如需其他樣式自行修改模板。
