无法加载spring PropertyPlaceHolderConfigure中的属性错误
我使用无法加载spring PropertyPlaceHolderConfigure中的属性错误,spring,Spring,我使用PropertyPlaceHolderConfigure，得到了以下代码： public static void main(String[] args) { Scanner sc=null; CustomerDTO dto=null; //create IOC Container ApplicationContext ctx=new FileSystemXmlApplicationContext("src/main/java/com/nt/c
PropertyPlaceHolderConfigurepublic static void main(String[] args) {
Scanner sc=null;
CustomerDTO dto=null;
//create IOC Container
ApplicationContext ctx=new FileSystemXmlApplicationContext("src/main/java/com/nt/cfgs/applicationContext.xml");
//get PropertyPlaaceHolderConfigurer OBJ
BeanFactoryPostProcessor bfpp=ctx.getBean("ppc",PropertyPlaceholderConfigurer.class);
bfpp.postProcessBeanFactory((ConfigurableListableBeanFactory)ctx);
sc=new Scanner(System.in);
System.out.println("Enter Customer NO: ");
int cno=sc.nextInt();
System.out.println("Enter Customer Name: ");
String cname=sc.next();
System.out.println("Enter Principal Amount:: ");
float pamt=sc.nextFloat();
System.out.println("Enter Rate of Interest: ");
float rate=sc.nextFloat();
System.out.println("Enter Time/Period: ");
float time=sc.nextFloat();
//set values to dto
dto=new CustomerDTO();
dto.setCno(cno);
dto.setCname(cname);
dto.setPamt(pamt);
dto.setRate(rate);
dto.setTime(time);
//getBean
LoanService service=ctx.getBean("service",LoanService.class);
System.out.println(service.calcIntrAmt(dto));
}

如何解决此问题？您应该将应用程序上下文放在src/main/resources/com/nt/cfgs/applicationContext.xml中，然后尝试使用“com/nt/cfgs/applicationContext.xml”来阅读它。。。您的类不会从项目的顶部执行，而是从目标文件夹中执行，因此它无法看到您相对于“目标”指示的路径
或者更好的是，使用类路径上下文读取器和路径“classpath:com/nt/cfgs/applicationContext.xml”…异常很简单。上面说
Exception in thread "main" org.springframework.beans.factory.BeanInitializationException: Could not load properties; nested exception is java.io.FileNotFoundException: src\main\java\com\nt\commons\DBDetails.properties
这意味着它无法在给定的路径中找到
