Resource leak: 'context' is never closed

spring实例化时

public void test2() {
    ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
    //配置文件中的id属性
    IHelloService service = (IHelloService) context.getBean("helloService");
    service.sayHello();

}

可以将前面用子类来写，并关闭

public void test2() {
    ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
    //配置文件中的id属性
    IHelloService service = (IHelloService) context.getBean("helloService");
    service.sayHello();
    context.close();
}
