我定义了一个看起来像这样的简单类

public class Spring1 {
    public static void main(String[] args) {
        ApplicationContext context = new  ClassPathXmlApplicationContext("spring.xml");

     }
}

我的配置文件是

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

</beans>

当我运行应用程序时，它显示以下错误

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory

我认为您没有包含“apache commons logging jar”。下载并将其添加到您的项目中

下载commons-logging并将 jar(s) 放在 WEB-INF/lib 中。Spring 框架带有很多库。确保您已在类路径中添加了所有必需的。

并且对于未来 - 谷歌搜索未找到的类名以查看它属于哪个库，下载它并将其放在类路径中。

org.apache.commons.logging.LogFactory与您的 Spring 版本不兼容。

下载JAR
