Question

我已经下载了Apache Ignite的2.7.5二进制文件。我在Cassandra-Ignite集成官方文档中提到了xml文件。但是，所有bean均无法加载。配置文件在我的桌面文件夹中。从我提取二进制zip的文件夹中运行Ignite。

错误：

var str1 = "do you ever looked", s1 = str1.split(' ');
var str2 = "do you fr ever looked", s2 = str2.split(' ');

let sims = Array.from(s1, (_,i) => Array.from(s2, () => '' + s1[i]));
console.log(sims);

配置文件：

Failed to instantiate Spring XML application context [springUrl=file:/C:/Users/Username/Desktop/ignite-con-new.xml, err=Configuration problem: Failed to import bean definitions from URL location

我知道它找不到bean的位置。您认为可能对此有何解决办法？

阅读的经验法则Spring错误一直向下滚动。

nested exception is java.io.FileNotFoundException: 
class path resource [org/apache/ignite/tests/cassandra/connection-settings.xml] 
cannot be opened because it does not exist

看起来该资源不在XML期望的位置。请注意，src/main/resources可以包含任意目录结构，例如src/main/resources/org/apache/ignite/tests/cassandra <-也许就是文件应该存放的位置？
