public static ApplicationContext applicationContext;
public static PreProfitTestCase preProfitTestCase;
public static PreProfitUrl preProfitUrl;
@BeforeClass
public void start(){
    if(!Application.started){
        applicationContext = SpringApplication.run(Application.class);
        Application.started = true;
    }else{
        applicationContext = Application.get();
    }
    preProfitUrl = applicationContext.getBean(PreProfitUrl.class);
    preProfitTestCase = applicationContext.getBean(PreProfitTestCase.class);
}
