處理程序處理失敗;嵌套的異常是java.lang.NoClassDefFoundError：org/apache/http/client/protocol/HttpClientContext

Question

我在NoClassDefFound異常中訪問spring-social鏈接和facebook。奇怪的是，我有一個項目使用相同的代碼進行連接，另一個使用nt。我已經通過他們兩個之間的差異，並沒有看到任何有意義的東西。

這是我得到的完整跟蹤。任何暗示或搜索方向是受歡迎的。

Answer 1

組織/阿帕奇/ HTTP /客戶/協議/ HttpClientContext是類從4.3（https://hc.apache.org/httpcomponents-client-4.3.x/httpclient/apidocs/org/apache/http/client/protocol/HttpClientContext.html）打包到httpcomponents-client中。我認爲你根本沒有正確的版本或項目。

嘗試添加此：

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

Answer 2

變化HTTP客戶端4.3.1，它應該工作... 也看看
