java - 谷歌日历: Cannot find com. google.api.client.json.JsonFactory.fromInputStream

标签 java json maven google-api google-api-java-client

我正在开发一个 Spring-MVC 应用程序，我试图在其中集成日历功能。不幸的是，由于 json 错误，我陷入了身份验证阶段本身。我正在尝试使用谷歌的示例代码，但它已经过时了，所以我做了一些修改。请看一下。 错误日志:

java.lang.NoSuchMethodError: com.google.api.client.json.JsonFactory.fromInputStream(Ljava/io/InputStream;Ljava/lang/Class;)Ljava/lang/Object;
    com.google.api.client.googleapis.auth.oauth2.GoogleClientSecrets.load(GoogleClientSecrets.java:167)
    com.journaldev.spring.utility.OAuth.authorize(OAuth.java:73)

Oauth 类，我在其中实现日历功能。

public class OAuth {

    private static final String APPLICATION_NAME = "appname";

    private static final java.io.File DATA_STORE_DIR =
            new java.io.File(System.getProperty("user.home"), "" +
                    "/Store/calendar_sample");

    private static FileDataStoreFactory dataStoreFactory;

    private static HttpTransport httpTransport;

    private static final com.google.api.client.json.JsonFactory JSON_FACTORY = JacksonFactory.getDefaultInstance();

    private static com.google.api.services.calendar.Calendar client;

    static final java.util.List<Calendar> addedCalendarsUsingBatch = Lists.newArrayList();

    public void authorizeAndTest(){

        try {
            httpTransport = new NetHttpTransport();
            dataStoreFactory = new FileDataStoreFactory(DATA_STORE_DIR);
            Credential credential = authorize();

            client = new com.google.api.services.calendar.Calendar.Builder(httpTransport,JSON_FACTORY,credential).setApplicationName(APPLICATION_NAME).build();

            showCalenders();
            addCalendarsUsingBatch();
            Calendar calendar = addCalendar();
            updateCalendar(calendar);
            addEvent(calendar);
            showEvents(calendar);
            deleteCalendarInBatch();
            deleteCalendar(calendar);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static Credential authorize() throws Exception{


        InputStream inputStream = new FileInputStream(new File("/home/akshay/c0cc3b4b7502.json"));


        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY,inputStream);

//发生在这一行。

   if (clientSecrets.getDetails().getClientId().startsWith("Enter")
            || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) {
        System.out.println(
                "Enter Client ID and Secret from https://code.google.com/apis/console/?api=calendar "
                        + "into calendar-cmdline-sample/src/main/resources/client_secrets.json");
        return null;
    }

    AuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(httpTransport,JSON_FACTORY,clientSecrets,
            Collections.singleton(CalendarScopes.CALENDAR)).setDataStoreFactory(dataStoreFactory).build();

    return new AuthorizationCodeInstalledApp(flow,new LocalServerReceiver()).authorize("user@gmail.com");
}

最佳答案

您需要考虑以下几点:

  1. 日历 API 不需要依赖项 com.google.gdata.core。除非您需要将其用于其他 Google API，否则可以将其删除

  2. 您有两个 google-http-client 实现:google-http-client-jackson 和 google-http-client-jackson2 。您需要删除其中之一。

  3. 您使用了不必要且过旧的依赖项，例如 google-api-client-auth-oauth2:1.2.3-alpha 和 google-api-client:1.4 .1-测试版

  4. google-api-services-calendar 和 google-http-client-jackson2 的版本不匹配。对于 google-http-client-jackson2:1.19.0，您需要使用 google-api-services-calendar:v3-rev121-1.19.0。请注意，HTTP 客户端的版本与日历客户端版本的后缀相同？

  5. 如果您想使用 LocalServerReceiver，则 google-oauth-client-java6 依赖项必须替换为 google-oauth-client-jetty 类。

最后，这是我的工作依赖项集和稍微更新的 OAuth 类:

    <dependency>
        <groupId>com.google.apis</groupId>
        <artifactId>google-api-services-calendar</artifactId>
        <version>v3-rev121-1.19.0</version>
    </dependency>

    <dependency>
        <groupId>com.google.http-client</groupId>
        <artifactId>google-http-client-jackson</artifactId>
        <version>1.19.0</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.security.oauth</groupId>
        <artifactId>spring-security-oauth2</artifactId>
        <version>2.0.3.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>com.google.oauth-client</groupId>
        <artifactId>google-oauth-client-jetty</artifactId>
        <version>1.19.0</version>
    </dependency>

请注意，您需要更改 json 文件的路径:

public class OAuth {

    private static final String APPLICATION_NAME = "APPNAME";

    private static final java.io.File DATA_STORE_DIR =
            new java.io.File(System.getProperty("user.home"), "" +
                    "/Store/calendar_sample");

    private static FileDataStoreFactory dataStoreFactory;

    private static HttpTransport httpTransport;

    private static final com.google.api.client.json.JsonFactory JSON_FACTORY = new JacksonFactory();

    private static com.google.api.services.calendar.Calendar client;


    public void authorizeAndTest() {

        try {
            httpTransport = new NetHttpTransport();
            dataStoreFactory = new FileDataStoreFactory(DATA_STORE_DIR);
            Credential credential = authorize();

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    private static Credential authorize() throws Exception {


        FileReader credentialsReader = new FileReader(new File("client_secret_47576556653-go0fkf4c56dohm6m16s2400qed5ps410.apps.googleusercontent.com.json"));

// It gives me an error for line below.
        GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, credentialsReader);
        if (clientSecrets.getDetails().getClientId().startsWith("Enter")
                || clientSecrets.getDetails().getClientSecret().startsWith("Enter ")) {
            System.out.println(
                    "Enter Client ID and Secret from https://code.google.com/apis/console/?api=calendar "
                            + "into calendar-cmdline-sample/src/main/resources/client_secrets.json");
            return null;
        }

        AuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(httpTransport, JSON_FACTORY, clientSecrets,
                Collections.singleton(CalendarScopes.CALENDAR)).setDataStoreFactory(dataStoreFactory).build();

        return new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user@gmail.com");
    }
