Question

我在访问spring-social链接和facebook时遇到NoClassDefFound异常。奇怪的是我有一个项目使用相同的连接代码和一个nt的代码。我已经通过他们中的两个之间的差异，并没有看到任何对我有意义。

这是我得到的完整痕迹。欢迎任何提示或搜索方向。

Answer 1

更改为HTTP客户端4.3.1，它应该工作... 还看看

https://issues.springsource.org/browse/SOCIALFB-144?page=com.atlassian.streams.streams-jira-plugin:activity-stream-issue-tab

Answer 2

org / apache / http / client / protocol / HttpClientContext是自4.3（https://hc.apache.org/httpcomponents-client-4.3.x/httpclient/apidocs/org/apache/http/client/protocol/HttpClientContext.html）以来在httpcomponents-client中打包的类。我认为你根本没有合适的版本或项目。

尝试添加此内容：

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

处理程序处理失败;嵌套异常是java.lang.NoClassDefFoundError：org / apache / http / client / protocol / HttpClientContext
