我在春天制作了一个简单的程序来解决这个错误。

----

我借助此链接。 http://www.javatpoint.com/steps-to-create-spring-application 我执行以下步骤

在此文件夹WEB-INF test.xml中创建一个xml

<?xml version="1.0" encoding="UTF-8"?>  
<beans  
    xmlns="http://www.springframework.org/schema/beans"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
    xmlns:p="http://www.springframework.org/schema/p"  
    xsi:schemaLocation="http://www.springframework.org/schema/beans  
               http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">  

<bean id="studentbean" class="test">  
<property name="name" value="Vimal Jaiswal"></property>  
</bean>  

</beans>  


public class test {
public static void main(String[] args) {
    System.out.println("----");
    ApplicationContext applicationContext = new ClassPathXmlApplicationContext("META-INF/test.xml");
;   
    //BeanFactory factory=new XmlBeanFactory(appContext);  

    Student student=(Student)applicationContext.getBean("studentbean");  
    student.displayInfo(); 
}
}

问题在于：

Caused by: java.io.FileNotFoundException: class path resource [META-INF/test.xml]

你的类路径中没有该文件..

将您的test.xml文件放入META-INF目录

对于新问题，在测试类中，您必须为name属性声明getter和setter ..
