Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: org/apache/http/client/HttpClient

Question

enter image description here

我尝试点击 API 然后出现了这种类型的错误 - org.springframework.web.util.NestedServletException: 处理程序调度失败；嵌套异常是 java.lang.NoClassDefFoundError: org/apache/http/client/HttpClient

Answer 1

确保您已经根据您使用的工具添加了对 apache http 组件的依赖。按照这个 link [apache http 组件的依赖][1]https://hc.apache.org/httpcomponents-client-ga/httpclient/dependency-info.html 添加依赖项。

Answer 2

NoClassDefFoundError 表示 class 在编译时可用但无法在运行时找到定义。尝试升级您的 httpclient depedency，

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.3</version>
</dependency>

然后运行clean install

Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: org/apache/http/client/HttpClient
