How to close a spring ApplicationContext?

Question

After my application finishes I want to close the spring context.
The relevant code has an ApplicationContext reference but I couldn't find a close method.

Answer 1

将您的ApplicationContext向下转换为ConfigurableApplicationContext ，它定义了close()方法：

((ConfigurableApplicationContext)appCtx).close();

Answer 2

You need to register a shutdown hook with the JVM as shown below:

((AbstractApplicationContext)appCtx).registerShutdownHook();

For more information see: Spring Manual: 3.6.1.6 Shutting down the Spring IoC container gracefully in non-web applications

Answer 3

If you initialise context like one below

ApplicationContext context = new ClassPathXmlApplicationContext(beansXML); 

clean context like these

((ClassPathXmlApplicationContext) context).close();

Answer 4

If Java SE 7 and later , don't close, use try-with-resources which ensures that each resource is closed at the end of the statement.

try(final AbstractApplicationContext applicationContext = new ClassPathXmlApplicationContext(new String[]{"classpath*:META-INF/spring/*.xml" }))
{
     //write your code
}

public static void main(String[] args) {
    ApplicationContext context=new ClassPathXmlApplicationContext("SpringCnf.xml");
    Resturant rstro1=(Resturant)context.getBean("resturantBean");
    rstro1.setWelcome("hello user");
    rstro1.welcomeNote();
    ((ClassPathXmlApplicationContext) context).close();
