无法使用Spring Framework运行应用程序

Question

我已经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>

当我运行该应用程序时，它显示以下错误

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

我帮我弄错了。

Answer 1

我想你还没有包括“apache commons logging jar”。 下载并将其添加到您的项目中

Answer 2

Donwload commons-logging并将jar放在WEB-INF / lib.Spring框架中，附带了很多库。 确保在类路径中添加了所有必需的内容。

而对于未来 - 谷歌找不到的类名称，看看它属于哪个库，下载并将其放在类路径上。

Answer 3

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

下载JAR
