我正在尝试获取要在应用程序中使用的数据库用户名和密码值。我正在使用entitymanager,但当打印这些值时,我会用星号将它们隐藏起来。如何将这些值隐藏起来而不使用星号?
控制器类
@Controller
public class AttendanceReportController {
@Autowired
private DepartmentService departmentService;
@Autowired
private ShiftMasterService shiftMasterService;
@Autowired
private EmployeeAttendanceService employeeAttendanceService;
@PersistenceContext
EntityManager entityManager;
@GetMapping("/AttendanceReport")
public String AttendanceReportPage() {
return "attendanceReport";
}
@ModelAttribute("depList")
public List<DepartmentMaster> getAllDeps() throws SQLException {
EntityManagerFactory emf = entityManager.getEntityManagerFactory();
Map<String, Object> emfProperties = emf.getProperties();
String url = (String) emfProperties.get("javax.persistence.jdbc.url");
String user = (String) emfProperties.get("javax.persistence.jdbc.user");
String password = (String) emfProperties.get("javax.persistence.jdbc.password");
System.out.println("URL : " + url);
System.out.println("Username : " + user);
System.out.println("Password : " + password);
return departmentService.getAllDep();
}
}
