我的spring Boot应用程序在本地系统上运行正常。在UAT中部署时，它不会调用服务层，而是会得到nullpointerException
在我看来（SubmissionView.java），我正在打电话
List<Employee> employeeList = TouchKitHRUI.getEmployeeService().findAll();
在TouchKitHRUI.java中
服务层已注入
@Autowired
private EmployeeService employeeService;
calling service layer
public static EmployeeServiceImpl getEmployeeService() {
return (EmployeeServiceImpl) ((TouchKitHRUI) getCurrent()).employeeService;
}
内部EmployeeServiceImpl.java
@Service
public class EmployeeServiceImpl implements EmployeeService {
@Override
public List<Employee> findAll() {
logger.error("inside employee service impl");
if(employeeRepo.findAll() != null)
return (List<Employee>) employeeRepo.findAll();
else
return (new ArrayList());
}
在UAT中，我得到了空指针异常。它不是在调用服务层。
如何解决此问题。
这是我的代码
