java - 应用程序无法加载 applicationContent.xml。为什么？

Question

我正在尝试一个 spring，其中我尝试使用 javabean 打印 Student 类的 name 属性就像

<bean id="studentbean" class="spring1.Student">  
<property name="name" value="krishna kant"></property>  
</bean>

这是我所拥有的图像

但是当我尝试运行时它说:类路径资源 [applicationContext.xml] 无法打开，因为它不存在

log4j:WARN No appenders could be found for logger (org.springframework.beans.factory.xml.XmlBeanDefinitionReader).
log4j:WARN Please initialize the log4j system properly.

还有一些其他问题也有同样的错误，但我无法将这些问题与我的问题联系起来。帮我找出我做错了什么。

//------------------Test.java-------------------
package spring1;

import org.springframework.beans.factory.BeanFactory;  
import org.springframework.beans.factory.xml.XmlBeanFactory;  
import org.springframework.core.io.ClassPathResource;  
import org.springframework.core.io.Resource;  

public class Test {  
public static void main(String[] args) {  
    Resource resource=new ClassPathResource("applicationContent.xml");  
    BeanFactory factory=new XmlBeanFactory(resource);  

    Student student=(Student)factory.getBean("studentbean");  
    student.displayInfo();  
}  
}
---------------------Student.java------------------------
package spring1;

public class Student {  
private String name;  

public String getName() {  
    return name;  
}  

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

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


---------------------applicationContent.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"

<bean id="studentbean" class="spring1.Student">  
<property name="name" value="krishna kant"></property>  
</bean>  

</beans> 

Answer 1

尝试 spring1/applicationContent.xml 而不是 applicationContent.xml，因为您的 applicationContent.xml 驻留在 spring1
