在Apex中发生异常时，把异常信息以邮件形式发生出去。

SendEmailUtils.cls

public with sharing class SendEmailUtils {
    public static void sendMailFromEx() {
        try {
            List<Opportunity> oppList = new List<Opportunity>();
            Opportunity oppItem1 = new Opportunity();
            oppItem1.Name = 'test001';
            oppItem1.StageName = 'Prospecting';
            //oppItem1.CloseDate = System.today();
            oppList.add(oppItem1);
            insert oppList;
        } catch (Exception ex) {
            List<OrgWideEmailAddress> owea = [select id from OrgWideEmailAddress limit 1];
            Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
            email.setToAddresses(new String[] { 'xxxx1987@163.com' });
            email.setSubject('my subject');
            // メール送信内容作成
            String body = String.format('my subject', new String[]{Datetime.now().format('yyyy-MM-dd kk:mm:ss.S', 'Asia/Tykyo'),
                                        String.ValueOf(ex.getMessage()),
                                        String.ValueOf(UserInfo.getUserName()),
                                        String.ValueOf(UserInfo.getSessionId()),
                                        String.ValueOf(ex.getStackTraceString())
                                    });
            email.setPlainTextBody(body);
            If (owea != null && owea.size() > 0) {
                email.setOrgWideEmailAddressId(owea.get(0).id);
            } else {
                email.setSenderDisplayName('Salesforce Support');
            }
            List<Messaging.SendEmailResult> results =
                Messaging.sendEmail(new Messaging.Email[] { email });
            if (!results.get(0).isSuccess()) {
                System.StatusCode statusCode = results.get(0).getErrors()[0].getStatusCode();
                String errorMessage = results.get(0).getErrors()[0].getMessage();
                system.debug(errorMessage);
            } else {
                system.debug('The email was sent successfully.');
            }
            throw ex;
        }
    }
}

为了测试，在开发者Console中调用当前Apex

看上边log，虽然显示发送成功，但是并没有收到邮件，看来在异常处理里边无法发送出去，只能另外想办法。

使用Platform Event方式实现

Platform Event是基于发布订阅模式，当salesforce发布消息以后，他的订阅者都有权力去订阅到发布的数据，当前场景下当异常发生时，发布消息，在通过trigger发送邮件信息。

自定义项目做成，用于保存error信息。

public with sharing class SendEmailUtils {
    public static void sendMailFromEx() {
        try {
            List<Opportunity> oppList = new List<Opportunity>();
            Opportunity oppItem1 = new Opportunity();
            oppItem1.Name = 'test001';
            oppItem1.StageName = 'Prospecting';
            //oppItem1.CloseDate = System.today();
            oppList.add(oppItem1);
            insert oppList;
        } catch (Exception ex) {
            List<SendEmail__e> needPublishSendEmailList = new List<SendEmail__e>();
            SendEmail__e sendEmailPublishItem = new SendEmail__e();
            sendEmailPublishItem.Exception_Content__c = String.ValueOf(ex.getMessage());
            sendEmailPublishItem.StackTrace__c = String.ValueOf(ex.getStackTraceString());
            needPublishSendEmailList.add(sendEmailPublishItem);
            if(!needPublishSendEmailList.isEmpty()) {
                List<Database.SaveResult> results = EventBus.publish(needPublishSendEmailList);
                for (Database.SaveResult sr : results) {
                    if (sr.isSuccess()) {
                        System.debug('Successfully published event.');
                    } else {
                        for(Database.Error err : sr.getErrors()) {
                            System.debug('Error returned: ' + err.getStatusCode() + ' - ' + err.getMessage());
                        }
                    }
                }
            }
            throw ex;
        }
    }
}

trigger SendEmailTrigger on SendEmail__e (after insert) {
