Question

我使用java.lang.StackOverflowError和text使用Java编写项目。我在加载Spring文件时遇到Maven dependencines问题，我试图找到问题，但我不知道它为什么不加载它。

错误信息：

apache

导致此错误的代码：

xml

也许您需要更多代码来帮助我？我认为使用从属关系是可以的，但我不确定。我的java.lang.NoClassDefFoundError: org/apache/http/client/config/RequestConfig$Builder at java.lang.Class.getDeclaredMethods0(Native Method) at

pom.xml文件位于项目<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.3.6</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpasyncclient</artifactId> <version>4.0.2</version> </dependency> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpmime</artifactId> <version>4.3.6</version> </dependency>文件夹

中

public-api-client-spring-context.xml

的内容

resources

有什么想法吗？

Answer 1

spring上下文配置文件中的这一行：

    <bean name="httpClient" class="org.apache.http.client.HttpClient" factory-bean="requestFactory"
        factory-method="getHttpClient"/>

尝试加载apache HTTP客户端，但显然在运行时它在类路径中不可用。您是否忘记在maven pom.xml中将其作为依赖项提及？或者你不是由maven构建安装包吗？

Answer 2

我解决了这个问题。我项目中有很多模块，其他模块覆盖org.apache.httpclient版本，导致冲突。
