我正在尝试使用 Spring 和 postgres 使用 maven 来实现 solr 搜索，但是在运行应用程序时我得到 404 异常
Exception processing loader WebappLoader[/solrjExample] background process
java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.StackOverflowError
我真的不明白问题是什么这是我的 spring-servlet：

还有我的 web.xml

<web-app id="WebApp_ID" version="2.4"

</servlet>
<servlet-mapping>
<servlet-name>solrjExample</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
我认为配置有问题或者我是 solr 新手。
谢谢您的帮助。
一般来说，这种错误是由于递归无限循环造成的。您是否在服务器启动时执行了一些自己的代码？
