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();

例外：

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（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

用于一般用途（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

请看一下如何选择正确的库：

如果您正在使用maven并且您的软件必须在servlet容器中运行，请尝试以下依赖项：

<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>

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