SpringBoot integrates Microsoft office 365 account solution (InsCode AI creation assistant)

SpringBoot integrates Microsoft office 365 account and requires the following steps:

1. Register the Azure AD application

To access Office 365 data using Microsoft Graph API, we need to first register an Azure AD application in order to obtain the corresponding application ID and secret.

2. Add API permissions

Add the "Microsoft Graph" permission to the application we created in the Azure portal so that we can access Office 365 data using the Microsoft Graph API.

3. Obtain access token

We need to use the OAuth 2.0 protocol to obtain the access token required to access Office 365 data. Spring Security OAuth 2.0 can be used to handle the OAuth 2.0 flow.

4. Call Microsoft Graph API

We can use Spring RestTemplate or Feign client to call Microsoft Graph API to obtain data.

Here is a sample code:

// 注入RestTemplate
@Autowired
private RestTemplate restTemplate;

// 注入OAuth2AuthorizedClientService
@Autowired
private OAuth2AuthorizedClientService oauth2ClientService;

// 发送请求获取数据
public SomeData getSomeDataFromOffice365() {
    
    
    OAuth2AuthenticationToken authentication = (OAuth2AuthenticationToken) SecurityContextHolder.getContext().getAuthentication();
    OAuth2AuthorizedClient oauth2Client = oauth2ClientService.loadAuthorizedClient(authentication.getAuthorizedClientRegistrationId(), authentication.getName());
    HttpHeaders headers = new HttpHeaders();
    headers.setBearerAuth(oauth2Client.getAccessToken().getTokenValue());
    HttpEntity<String> entity = new HttpEntity<>("parameters", headers);
    ResponseEntity<SomeData> response = restTemplate.exchange("https://graph.microsoft.com/v1.0/me", HttpMethod.GET, entity, SomeData.class);
    return response.getBody();
}

The above code demonstrates how to use OAuth2AuthorizedClientService and RestTemplate to access the Microsoft Graph API. We can also use the Feign client to call the API, which also requires configuring the OAuth 2.0 client.
