Can we use @autowired in jsp. If yes then how.?

Question

I am building a web application using spring and hibernate. I wanted to build the server side table for that I need a method that is written in Service class. But to execute it successfully I need to autowire it to the repected class as for now it is giving a Null Pointer Exception accessing the table.

No you can't use @autowired in JSP. If you need a bean in JSP, you can use the following :

ApplicationContext ac = RequestContextUtils.getWebApplicationContext(request);
ac.getBean("yourBeanName");

Edited to :-

Example Bean :

@Component("abcBean")
public Abc{

    public void sysout(){
        System.out.printn("Hello world");
    }

}

In JSP:

You can use this spring managed singleton bean as:

ApplicationContext ac = RequestContextUtils.getWebApplicationContext(request);
Abc abc = (Abc) ac.getBean("abcBean");
abc.sysout();

Please post if anything else is required.
