Springboot错误处理(Springboot error handling)
我正在开发一个处理登录的示例spring-boot API，但是API工作正常，但在处理错误时遇到问题。 我在教程中看到的所有错误处理都是在控制器中完成的，但是我的逻辑处于服务中，并且在那里我想进行错误处理。
我怎样才能在服务中实现错误处理不同类型的错误，或者是否认为这是错误的做法。 我目前的问题是，我的错误消息如下所示：
{ "message": "Please Activate account before attempting to Sign in", "token": " ", "accountLocked": false, "accountEnabled": false, "status": false, "balance": " ", "profileImage": null, "roles": null, "baraAuthorities": null, "customerNumber": 0, "userEmail": "", "name": "" }不过，我希望只有消息和状态显示并隐藏了答案中的其余部分，我该如何实现这一点：
{ "message": "Please Activate account before attempting to Sign in", "status": false }这是我的LoginService代码：
@Service public class LoginService implements UserDetailsService { @Autowired private UserLoginRepository loginRepository; @Autowired private LoginInformationRepository logininfoRepository; BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder(); String balance, message, pin, token, userEmail, name, profileImage = ""; Boolean status, successStatus, accounState = false; int customerNumber, attempts; List<Roles> userRoles = new ArrayList(); private boolean userNameExist(String username) { UserLogin user = loginRepository.findByUsername(username); if (user != null) { return true; } return false; } public LoginResponse verifyLoginDetails(LoginObject user) throws LoginException { AuthoritiesKeys userAuth = new AuthoritiesKeys(); Merchant searchedMerchant = merchantRepository.findByUserlogin_LoginCredentialsID(userdetails.getLoginCredentialsID()); DateUtility currentDate = new DateUtility(); Boolean status = false; if (userdetails == null) { return new LoginResponse("Unable to Login. Please check login details and try again",status); } else { pin = user.getPassword(); attempts = logininfoRepository.countByTodayDateAndUserLoginLoginCredentialsIDAndLoginSuccessStatusFalse(currentDate.getCurrentDate(), userdetails.getLoginCredentialsID()); if (attempts < 3) { if (bCryptPasswordEncoder.matches(pin, userdetails.getPassword())) { if (userdetails.isEnabled() == true) { if (searchedMerchant != null) { message = "Logged in Successfully"; status = userdetails.isAccountNonLocked(); accounState = userdetails.isEnabled(); userRoles = (List<Roles>) userdetails.getAuthorities(); balance = searchedMerchant.getAccount().getBalance().toString(); successStatus = true; customerNumber = searchedMerchant.getMerchantNumber(); userEmail = searchedMerchant.getEmail(); name = searchedMerchant.getBusinessName(); return new LoginResponse(message, token, accounState, status, userRoles, successStatus, balance, userAuth, profileImage, customerNumber, userEmail, name); } else { return new LoginResponse("Error Merchant Information Error . Please contact the team",status); } } else { return new LoginResponse("Please Activate account before attempting to Sign in",status); } } else { return new LoginResponse("Wrong Username or Password",status); } } else { userdetails.setAccountNonLocked(false); userdetails.setEnabled(false); loginRepository.save(userdetails); return new LoginResponse("Too many attempts account has been locked",status); } } }这是我的LoginResponse代码：
public class LoginResponse { private String message; private String token; private Boolean accountLocked; private Boolean accountEnabled; private Boolean status; private String balance; private String profileImage; List<Roles> roles = new ArrayList<>(); AuthoritiesKeys baraAuthorities = new AuthoritiesKeys(); private int customerNumber; private String userEmail; private String name; public LoginResponse() { } public LoginResponse(String message, Boolean status) { this.message = message; this.status = status; } public LoginResponse(String message, String token, Boolean accountLocked, Boolean accountEnabled, List<Roles> myroles, Boolean status, String balance, AuthoritiesKeys userBaraAuthorities, String profileImage, int customerNumber, String userEmail, String name) { this.message = message; this.token = token; this.accountLocked = accountLocked; this.accountEnabled = accountEnabled; this.status = status; this.balance = balance; this.roles = myroles; this.baraAuthorities = userBaraAuthorities; this.profileImage = profileImage; this.customerNumber = customerNumber; this.userEmail = userEmail; this.name = name; } … // left getter and setters for brevity }这是我的LoginController代码：
@RestController @Api(value = "Login API", produces = MediaType.APPLICATION_JSON_VALUE) public class UserLoginController { @Autowired private LoginService loginService; @RequestMapping(method = RequestMethod.POST, value = "/api/usermanagement/user/login") @ApiOperation("login registered user") @ApiResponses(value = { @ApiResponse(code = 200, message = "OK", response = ResponseMessage.class)}) public LoginResponse Login(@Valid @RequestBody LoginObject credentails) throws LoginException { return loginService.verifyLoginDetails(credentails); } }I am developing a sample spring-boot API that handles login, the API works fine however , I am having a problem during error handling. All the error handling I have seen in tutorials is done in the controller, however my logic is in the service and thats where I would like to do error handling.
How can I achieve error handling of different type of errors in the service or is it considered bad practice to do so. My current problem is that my error message looks like this :
{ "message": "Please Activate account before attempting to Sign in", "token": " ", "accountLocked": false, "accountEnabled": false, "status": false, "balance": " ", "profileImage": null, "roles": null, "baraAuthorities": null, "customerNumber": 0, "userEmail": "", "name": "" }However I would like to have just the message and the status show and hide the rest in the response, how do I achieve this :
{ "message": "Please Activate account before attempting to Sign in", "status": false }This is my code for LoginService :
@Service public class LoginService implements UserDetailsService { @Autowired private UserLoginRepository loginRepository; @Autowired private LoginInformationRepository logininfoRepository; BCryptPasswordEncoder bCryptPasswordEncoder = new BCryptPasswordEncoder(); String balance, message, pin, token, userEmail, name, profileImage = ""; Boolean status, successStatus, accounState = false; int customerNumber, attempts; List<Roles> userRoles = new ArrayList(); private boolean userNameExist(String username) { UserLogin user = loginRepository.findByUsername(username); if (user != null) { return true; } return false; } public LoginResponse verifyLoginDetails(LoginObject user) throws LoginException { AuthoritiesKeys userAuth = new AuthoritiesKeys(); Merchant searchedMerchant = merchantRepository.findByUserlogin_LoginCredentialsID(userdetails.getLoginCredentialsID()); DateUtility currentDate = new DateUtility(); Boolean status = false; if (userdetails == null) { return new LoginResponse("Unable to Login. Please check login details and try again",status); } else { pin = user.getPassword(); attempts = logininfoRepository.countByTodayDateAndUserLoginLoginCredentialsIDAndLoginSuccessStatusFalse(currentDate.getCurrentDate(), userdetails.getLoginCredentialsID()); if (attempts < 3) { if (bCryptPasswordEncoder.matches(pin, userdetails.getPassword())) { if (userdetails.isEnabled() == true) { if (searchedMerchant != null) { message = "Logged in Successfully"; status = userdetails.isAccountNonLocked(); accounState = userdetails.isEnabled(); userRoles = (List<Roles>) userdetails.getAuthorities(); balance = searchedMerchant.getAccount().getBalance().toString(); successStatus = true; customerNumber = searchedMerchant.getMerchantNumber(); userEmail = searchedMerchant.getEmail(); name = searchedMerchant.getBusinessName(); return new LoginResponse(message, token, accounState, status, userRoles, successStatus, balance, userAuth, profileImage, customerNumber, userEmail, name); } else { return new LoginResponse("Error Merchant Information Error . Please contact the team",status); } } else { return new LoginResponse("Please Activate account before attempting to Sign in",status); } } else { return new LoginResponse("Wrong Username or Password",status); } } else { userdetails.setAccountNonLocked(false); userdetails.setEnabled(false); loginRepository.save(userdetails); return new LoginResponse("Too many attempts account has been locked",status); } } }This is my code for LoginResponse :
public class LoginResponse { private String message; private String token; private Boolean accountLocked; private Boolean accountEnabled; private Boolean status; private String balance; private String profileImage; List<Roles> roles = new ArrayList<>(); AuthoritiesKeys baraAuthorities = new AuthoritiesKeys(); private int customerNumber; private String userEmail; private String name; public LoginResponse() { } public LoginResponse(String message, Boolean status) { this.message = message; this.status = status; } public LoginResponse(String message, String token, Boolean accountLocked, Boolean accountEnabled, List<Roles> myroles, Boolean status, String balance, AuthoritiesKeys userBaraAuthorities, String profileImage, int customerNumber, String userEmail, String name) { this.message = message; this.token = token; this.accountLocked = accountLocked; this.accountEnabled = accountEnabled; this.status = status; this.balance = balance; this.roles = myroles; this.baraAuthorities = userBaraAuthorities; this.profileImage = profileImage; this.customerNumber = customerNumber; this.userEmail = userEmail; this.name = name; } … // left getter and setters for brevity }This my code for LoginController :
@RestController @Api(value = "Login API", produces = MediaType.APPLICATION_JSON_VALUE) public class UserLoginController { @Autowired private LoginService loginService; @RequestMapping(method = RequestMethod.POST, value = "/api/usermanagement/user/login") @ApiOperation("login registered user") @ApiResponses(value = { @ApiResponse(code = 200, message = "OK", response = ResponseMessage.class)}) public LoginResponse Login(@Valid @RequestBody LoginObject credentails) throws LoginException { return loginService.verifyLoginDetails(credentails); } }

解决这个问题的一种方法是首先将
Door *关闭。 但是，为了减少这种类型的安全性，你应该使用dynamic_cast<Door *>()。 如果Entity还没有虚拟方法，则可以添加虚拟析构函数。class Entity { //... virtual ~Entity () {} }; void foo (Entity *e) { //... Door *door = dynamic_cast<Door *>(e); if (door) { if (door->isOpen()) { //... } } //... }One way to solve this is with a down cast to a
Door *first. However, in order for this down cast to be type safe, you should usedynamic_cast<Door *>(). IfEntitydoes not already have a virtual method, you can add a virtual destructor.class Entity { //... virtual ~Entity () {} }; void foo (Entity *e) { //... Door *door = dynamic_cast<Door *>(e); if (door) { if (door->isOpen()) { //... } } //... }
