java - 我使用 GoogleAPI 时 Tomcat 启动错误

Question

我对 GoogleAPI 有一些疑问。

Tomcat 工作正常，但是当我写那些时，我的 tomcat 不能正常工作。

HttpTransport transport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();

这是我的 Controller 。

                    // Get profile information from payload
                    String email = payload.getEmail();
                    boolean emailVerified = Boolean.valueOf(payload.getEmailVerified());
                    String name = (String) payload.get("name");

                    String givenName = (String) payload.get("given_name");

                    // Use or store profile information
                    // ...
                     System.out.println("User ID: " + userId);

                } else {
                    System.out.println("Invalid ID token.");
                }   
    }
}

这是错误的。

条件:jdk 1.8，Tomcat 8.5

请帮我解决这个错误。

如果您想了解更多信息，请告诉我。我会上传它。

谢谢。

检查这一行:

java.lang.NoClassDefFoundError: com/google/api/client/http/HttpTransport

您需要在来自 here 的 Tomcat 类路径中添加 google-api-client jar 文件
