Line Notify 提供了我們可以去查詢使用者的token狀態和撤銷使用者的token功能，這些都可以幫助我們更方便的設置Notify設定。

查詢使用者token狀態

public static LineNotifyCheckResponse checkTokenStatus(String token) {
		HttpHeaders headers = new HttpHeaders();
		headers.setBearerAuth(token);
		HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<>(headers);
		ResponseEntity<LineNotifyCheckResponse> lineNotifyCheckResponse = 
		restTemplate.exchange(LineNotifyUrl.TOKEN_STATUS_CHECK.getUrl(), 
				LineNotifyUrl.TOKEN_STATUS_CHECK.getHttpMethod(), 
				entity, 
				LineNotifyCheckResponse.class);
		if(!lineNotifyCheckResponse.getStatusCode().equals(HttpStatus.OK)) {
			throw new LineNotifyUtilException(
					LineNotifyErrorEnum.TOKEN_STATUS_CHECK_ERROR.getError(),
					LineNotifyErrorEnum.TOKEN_STATUS_CHECK_ERROR.getMessage()
					);
		}
		return lineNotifyCheckResponse.getBody();
	}

LineNotifyCheckResponse

@Data
public class LineNotifyCheckResponse {
	
	private Integer status;
	private String message;
	private String targetType;
	private String target;

		HttpHeaders headers = new HttpHeaders();
		headers.setBearerAuth(token);
		HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<>(headers);
		ResponseEntity<LineNotifyRevokeResponse> lineNotifyRevokeResponse = 
		restTemplate.exchange(LineNotifyUrl.TOKEN_REVOKE.getUrl(), 
				LineNotifyUrl.TOKEN_REVOKE.getHttpMethod(), 
				entity, 
				LineNotifyRevokeResponse.class);
		if(!(lineNotifyRevokeResponse.getStatusCode().equals(HttpStatus.OK))&&
		   !(lineNotifyRevokeResponse.getStatusCode().equals(HttpStatus.UNAUTHORIZED))
			 ) {
			throw new LineNotifyUtilException(
					LineNotifyErrorEnum.TOKEN_REVOKE_FAIL.getError(),
					LineNotifyErrorEnum.TOKEN_REVOKE_FAIL.getMessage()
					);
