进程已结束,退出代码1

上面就是报错代码，下面是test类的源码

package test;

import dao.TestDaoImpl;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.core.io.FileSystemResource;

public class Test_SSM {
    public static void main(String[] args)
    {
//        用下面这行代码就不会报错
        //BeanFactory appCon=new XmlBeanFactory(new FileSystemResource("E:\\ideaprojects\\gradle_test\\src\\main\\resources\\applicationContext.xml"));
        ApplicationContext appCon=new ClassPathXmlApplicationContext("applicationContext.xml");
        TestDaoImpl tt= (TestDaoImpl) appCon.getBean("test");
        tt.sayHello();
    }

}

用淘汰了的

BeanFactory appCon=new XmlBeanFactory(new FileSystemResource("E:\\ideaprojects\\gradle_test\\src\\main\\resources\\applicationContext.xml"));

就不会报错但是用

 ApplicationContext appCon=new ClassPathXmlApplicationContext("applicationContext.xml");

就会报上面的那种错所以应该不是xml文件的问题，但是我一直找不到原因啊

Answer 1

applicationContext.xml前面带个 classpath: 试试看
