I can get access token with POSTMAN call by passing below parameters,

POST URL : https://api.sandbox.paypal.com/v1/oauth2/token

Authorization Type : Basic Auth

Username : MY_CLIENT_ID

Password : MY_SECRET

Headers Content-Type : application/x-www-form-urlencoded

Body grant_type : client_credentials

Please let me know, how can I set above details in REST TEMPLATE call in spring boot to get access token

You need to set authorization as part of header only. Username and Password are Base64 encoded when you send the request; you need to do the same in Java before requesting for access token. - Akash
Assuming you know how to make restTemplate call in Spring boot. If not, please go through the tutorial spring.io/guides/gs/consuming-rest first - Akash

you can refer to the following code

public void run(String... args) throws Exception {
        StringHttpMessageConverter stringHttpMessageConverter = new StringHttpMessageConverter(StandardCharsets.UTF_8);
        RestTemplate restTemplate = new RestTemplateBuilder()
                .setConnectTimeout(Duration.ofSeconds(60))
                .additionalMessageConverters(stringHttpMessageConverter)
                .build();

        String uri = "https://api.paypal.com/v1/oauth2/token?grant_type=client_credentials";
        String username = "yourAppClientId";
        String password = "yourAppPwd";

        HttpHeaders basicAuth = new HttpHeaders() {{
            String auth = username + ":" + password;
            byte[] encodedAuth = Base64.encodeBase64(
                    auth.getBytes(StandardCharsets.US_ASCII));
            String authHeader = "Basic " + new String(encodedAuth);
            set("Authorization", authHeader);
        }};

        ResponseEntity<String> response = restTemplate.exchange
                (uri, HttpMethod.POST, new HttpEntity<>(basicAuth), String.class);
        System.out.println(response.getBody());
    }
