SpringBoot MockBean not available in new java thread

In my testcase, I call my two spring bean in my testcase. following is the sample code. the FundService mock is not correct in callbackService.callback() call, I found if I create a new Thread, the mockbean mock is not avaliable in the new Thread.

public class TestTopUpServcie {

    @MockBean
    private FundService fundservice;

    @Autowired
    private TopUpService topupService;

    @Autowired
    private CallbackService. callbackService;

    @Test
    public void testTopUp(){
        // do the mock
        Mockito.doReturn(new TopupResponse()).when(fundservice).topUp(any());

        // in this method call, the mock(fundService.topUp()) is correct, return the TopUpResponse object.
        topupService.topup();

        // in this method call,  it will create new Thread to do some biz logic,  in new Thread,  the mock fundservice not work. only return null.
        callbackService.callback();

    }

}

Thanks wilkinsona, but for my case, I cannot upgrade the spring boot version, do you have any other suggestions?

I'm afraid not. Spring Boot 1.5.x is no longer supported either commercially or in open source. Someone on Stack Overflow may be able to help you, but you will have to provide a minimal, reproducible example that makes it as easy as possible for them to reproduce the problem.
