进程已结束，退出代码为 1

初始代码：

public class TestHelloSpring {
    public static void main(String[] args){
        //初始化spring容器，加载applicationContext.xml配置
        ClassPathXmlApplicationContext applicationContext=
        new ClassPathXmlApplicationContext("applicationContext.xml");
        //通过容器获取配置中helloSpring的实例
        HelloSpring helloSpring=(HelloSpring)applicationContext.getBean("HelloSpring");
        //调用方法
        helloSpring.show();
    }
}

方法一：将resources标记为资源根（未解决）
变成一下形式：

方法二(最终方法)：修改大小写

getBean(“HelloSpring”)中将小写误写为大写

将大写给位小写//最终修改代码：

public class TestHelloSpring {
    public static void main(String[] args){
        //初始化spring容器，加载applicationContext.xml配置
        ClassPathXmlApplicationContext applicationContext=
        new ClassPathXmlApplicationContext("applicationContext.xml");
        //通过容器获取配置中helloSpring的实例
        HelloSpring helloSpring=(HelloSpring)applicationContext.getBean("helloSpring");
        //调用方法
        helloSpring.show();
    }
