javamail微软邮箱账号在oauth2认证方式下使用exchange协议进行发送邮件

一、在 Microsoft Entra管理中心进行应用注册获取应用程序id、租户id和密钥的值

1、应用注册

2、应用注册完成后，获取应用程序id和租户id

3、生成密钥，并记录密钥的值


4、添加权限


然后需要管理员同意添加权限

二、废话不多说，直接上代码

        String mailAddress = "邮箱账号";
        String tenant_id = "租户id";
        String client_id = "应用id";
        String client_secret = "密钥的值";//注意不是密钥的id
        String scope = "https://outlook.office365.com/.default";

        HttpClient httpClient = new HttpClient();

            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            postMethod.releaseConnection();
        }

        ExchangeService service = new ExchangeService();

        service.setCredentials(new OAuth2Credentials(token));
        service.setTraceEnabled(true);
        service.traceMessage(TraceFlags.EwsRequest, "office365");
        service.setImpersonatedUserId(new ImpersonatedUserId(ConnectingIdType.SmtpAddress, mailAddress));
        service.setUrl(new URI("https://outlook.office365.com/ews/exchange.asmx"));
        //service.setUrl(new URI("https://partner.outlook.cn/ews/exchange.asmx"));//中国版（21v世纪互联运营的）的微软邮箱账号需要设置这个地址
        service.getHttpHeaders().put("X-AnchorMailbox", mailAddress);

        EmailMessage msg = new EmailMessage(service);
        msg.setFrom(new EmailAddress("mailAddress", mailAddress));
        msg.getToRecipients().add(new EmailAddress("收件人邮箱昵称", "收件人邮箱地址"));
        msg.setSubject("邮件oauth2测试");
        MessageBody messageBody = new MessageBody();
        messageBody.setBodyType(BodyType.Text);
        messageBody.setText("哈哈哈哈");
        msg.setBody(messageBody);

        msg.setImportance(Importance.Normal);
        msg.send();
    }

     static class OAuth2Credentials extends ExchangeCredentials {
         private String accessToken;

         public OAuth2Credentials(String accessToken) {
             Preconditions.checkNotNull(accessToken);
             this.accessToken = accessToken;
         }

         @Override
         public void prepareWebRequest(HttpWebRequest client)
                 throws URISyntaxException {
             super.prepareWebRequest(client);
             if (client.getHeaders() != null) client.getHeaders().put("Authorization", "Bearer " + accessToken);
         }
    }
}

这样就可以在oauth2认证方式下使用exchange协议进行发送邮件或者接收邮件了
