大家好，我是讯享网，很高兴认识大家。

在工作中，经常遇到警告、异常等数据，需要以某些方式告知维护人员。比较通常的方式是邮件，也有用企业微信的。通常邮件使用apache的emali工具类。

添加maven依赖：

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-email --> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-email</artifactId> <version>1.5</version> </dependency>

application.yml添加配置

讯享网srping: email: host: .com #邮件服务器 from: @.com #邮件发送账户 username: @.com #发送账户的用户名 password: #发送账户的密码 defaultEncoding: UTF-8 to: @.com #接收账户 title: #邮箱标题

邮箱配置类

@Configuration @ConfigurationProperties(prefix = "spring.email") public class EmailConfig { private String host; private String from; private String username; private String password; private String defaultEncoding; private String to; private String title; }

发送邮件工具类

讯享网public class EmailUtil { private EmailConfig emailConfig; private Logger logger = LoggerFactory.getLogger(getClass()); public EmailUtil(EmailConfig emailConfig) { this.emailConfig = emailConfig; } public <T> void sendMsg(T e) { try { Email email = initEmail(emailConfig); sendData(email, e); email.send(); } catch (EmailException ex) { logger.error("=============邮件发送失败============", ex); } } private Email initEmail(EmailConfig emailConfig) throws EmailException { Email email = new SimpleEmail(); email.setHostName(emailConfig.getHost()); email.setCharset(emailConfig.getDefaultEncoding()); email.setSmtpPort(25); email.setAuthentication(emailConfig.getUsername(), emailConfig.getPassword()); //email.setSSLOnConnect(true); email.setFrom(emailConfig.getFrom()); email.setSubject(emailConfig.getTitle()); //email.setMsg(errMsg); email.addTo(emailConfig.getTo().split(";")); //email.send(); return email; } public static void send(Email email) throws EmailException { email.send(); } private <T> void sendData(Email email, T e) throws EmailException { if (e instanceof String) { email.setMsg((String) e); } else if (e instanceof Exception) { Exception ex = (Exception) e; String errMsg = ex.getMessage() + "\n"; for (StackTraceElement element : ex.getStackTrace()) { errMsg += "\tat " + String.valueOf(element); } email.setMsg(errMsg); } } }

使用的地方这样调

@Autowired private EmailConfig emailConfig; @Test public void testSendEmail() { try { int bigDecimal = 10/0; }catch (Exception e){ new EmailUtil(emailConfig).sendMsg(e); } }
