为什么我会得到;java.lang.NoClassDefFoundError:kong/unirest/unirest";?
我正在创建一个执行POST操作的Java应用程序。我需要对body执行HttpRequestWithBody以发送JSONObject。我正在使用Unirest来完成这项任务。在调试过程中,程序在创建请求并指定URL的行停止 代码如下:为什么我会得到;java.lang.NoClassDefFoundError:kong/unirest/unirest";?,java,apache-httpcomponents,unirest,Java,Apache Httpcomponents,Unirest,我正在创建一个执行POST操作的Java应用程序。我需要对body执行HttpRequestWithBody以发送JSONObject。我正在使用Unirest来完成这项任务。在调试过程中,程序在创建请求并指定URL的行停止 代码如下: HttpRequestWithBody response = Unirest.post("{{URL}}"); // This line has the problem try { *** adds headers and body *** } catc

我尝试添加其他apache.httpcomponents

感谢您的帮助。异常堆栈跟踪中的这一行表示您的类路径中没有类Unirest,线程“main”java.lang.NoClassDefFoundError:kong/Unirest/Unirest 然而,您似乎在依赖项部分添加了它的lib,由maven来解决,但它在“提供的范围”中,这意味着您希望其他东西为您提供它,例如ApplicationServer,但我认为这不是您的环境 因此,您是否可以删除为该依赖项提供的那一行
