为什么我不使用FileSystemResource类读取xml文件

问题:

我创建了一个程序,它将使用FilesystemResource从指定路径读取我的applicationContext.xml文件并调用B.Method。 我无法理解为什么我会收到这样的错误:

  

任何人都可以指导我如何解决这个问题:

以下是代码

public static void main(String[] args) {
    Resource res=null;
    BeanFactory factory=null;
    Object obj=null;
    WishMessageGenerator generator=null;
    //Locate Cfg File
    res=new FileSystemResource("com/jc/cfgs/applicationContext.xml");
    //Create IOC Container      
    factory=new XmlBeanFactory(res);
    //getBean Class Object      
    obj=factory.getBean("wish");
    //TypeCasting       
    generator=(WishMessageGenerator)obj;
    //Invoke Businees Method        
    System.out.println("Message ="+generator.wishMsg("jalaj"));

}

}

错误显示:

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from file [/Users/mansi/Desktop/springapp/SpringApp4/com/jc/cfgs/applicationContext.xml]; nested exception is java.io.FileNotFoundException: com/jc/cfgs/applicationContext.xml (No such file or directory)

答案 0 :(得分:0)

如果资源位于类路径中,则不应使用旨在指定绝对路径的FileSystemResource

ClassPathResource也是org.springframework.core.io.Resource实施更合适。

在您的实际代码中,src文件夹位于类路径中,因此这应该没问题:

res = new ClassPathResource("com/jc/cfgs/applicationContext.xml");
