I am struggling with a NoClassDefFound exception in access to spring-social linked in and facebook. What is strange is I have a project which works using the same code for connexion and one which does nt. I have gone thru the differences between the 2 of them and doesnt see any which makes sense to me.

Here is the full trace I get. Any hint or search direction is welcome.

    type Exception report
    message Handler processing failed; nested exception is java.lang.NoClassDefFoundError:     org/apache/http/client/protocol/HttpClientContext

    description The server encountered an internal error that prevented it from fulfilling this request.exception

org/apache/http/client/protocol/HttpClientContext 是自 4.3 以来封装在 httpcomponents-client 中的一个类（https://hc.apache.org/httpcomponents-client-4.3.x/httpclient/apidocs/org/apache/http /client/protocol/HttpClientContext.html）。我认为您根本没有正确的版本或项目。

尝试添加这个：

<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.3.2</version>
</dependency>

更改为 HTTP Client 4.3.1，它应该可以工作......也看看
