java - 如何在没有 appengine 的情况下使用 google-api-services-plus-v1

Question

我想在 java 控制台应用程序中使用 google-api-services-plus-v1 lib，但每当执行以下代码时，我都会收到 ClassDefFoundError:

Plus.Activities.Search req = service.activities().search(q); 
ActivityFeed feed = req.execute();

异常(exception):

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/appengine/api/urlfetch/HTTPMethod
at com.google.api.client.extensions.appengine.http.UrlFetchTransport.buildRequest(UrlFetchTransport.java:125)

如何添加这些库？

Answer 1

您正在使用 AppEngine 的 google-api-java-client 发行版:

以下是 Servlet 应用程序所需的依赖项文件夹中的 jar 文件(或每个依赖项的较新兼容版本):

google-api-client-1.17.0-rc.jar
google-api-client-servlet-1.17.0-rc.jar
google-oauth-client-1.17.0-rc.jar
google-oauth-client-servlet-1.17.0-rc.jar
google-http-client-1.17.0-rc.jar
commons-logging-1.1.1.jar
gson-2.1.jar
httpclient-4.0.3.jar
httpcore-4.0.1.jar
jackson-core-asl-1.9.4.jar
jackson-core-2.1.3.jar
jdo2-api-2.3-eb.jar
jsr305-1.3.9.jar
protobuf-java-2.2.0.jar
transaction-api-1.1.jar
xpp3-1.1.4c.jar

通用(命令行):

google-api-client-1.17.0-rc.jar
google-oauth-client-1.17.0-rc.jar
google-http-client-1.17.0-rc.jar
commons-logging-1.1.1.jar
gson-2.1.jar
httpclient-4.0.3.jar
httpcore-4.0.1.jar
jackson-core-asl-1.9.4.jar
jackson-core-2.1.3.jar
jsr305-1.3.9.jar
protobuf-java-2.2.0.jar
xpp3-1.1.4c.jar

如果您喜欢 Maven 并且您的软件必须在 servlet 容器中运行，请尝试此依赖项:

<dependency>
      <groupId>com.google.api-client</groupId>
      <artifactId>google-api-client-servlet</artifactId>
      <version>1.17.0-rc</version>
    </dependency>

而不是

 <dependency>
      <groupId>com.google.api-client</groupId>
      <artifactId>google-api-client-appengine</artifactId>
      <version>1.17.0-rc</version>
    </dependency>
