Prototype Bean doesn't get autowired as expected

Question

TestController.java

@RestController
public class TestController {

    @Autowired
    private TestClass testClass;

    @RequestMapping(value = \"/test\", method         


        

Answer 1

As mentioned, controller is by default singleton, that's why instantiation and injection of TestClass is performed only once on its creation.

Solution can be to inject application context and get the bean manually:

@RestController
public class TestController {

    @Autowired
    ApplicationContext ctx;

    @RequestMapping(value = "/test", method = RequestMethod.GET)
    public void testThread(HttpServletResponse response) throws Exception {
        ((TestClass) ctx.getBean(TestClass.class)).doSomething();
    }
}

Now, when a TestClass bean is requested, Spring knowing that it is @Prototype, will create a new instance and return it.

Another solution is to make the controller @Scope("prototype").
