BeanDefinitionStoreException：IOException 从类路径资源解析 XML 文档 [applicationContext]

Question

我正在尝试创建我的第一个 Spring 应用程序。它显示以下错误：

log4j:WARN No appenders could be found for logger (org.springframework.beans.factory.xml.XmlBeanDefinitionReader).
log4j:WARN Please initialize the log4j system properly.
Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [applicationContext]; nested exception is java.io.FileNotFoundException: class path resource [applicationContext] cannot be opened because it does not exist

GetterSetter.java

package com.spring1;

private String name;

public String getName()
{
    return name;
}

public void setName(String name)
{
    this.name=name;
}

public void displayInfo()
{
    System.out.println("hello "+name);
}

FirstSpring1.java

package com.spring1;

public static void main(String[] args)
{
    GetterSetter gt=new GetterSetter();
    gt.setName("Google");
    gt.displayInfo();

    Resource resource = new ClassPathResource("applicationContext");
    BeanFactory factory = new XmlBeanFactory(resource);
    GetterSetter gt1 = (GetterSetter)factory.getBean("name1");
    gt1.displayInfo();
}

XML 文件位于src 文件夹中。

代替：

Resource resource = new ClassPathResource("applicationContext");

用途：

Resource resource = new ClassPathResource("applicationContext.xml");
