Cannot pass a null GrantedAuthority collection

Cannot pass a null GrantedAuthority collection - java

Hey i'm a newbie at Spring Boot i'm trying to make a spring secrity project
but i had this problem and i'm stuck
i will show you samples of the codes:
#Service
public class CustomUserDetailsService implements UserDetailsService {
#Autowired
private UserRepository userDao;
#Autowired
private PasswordEncoder bcryptEncoder;
#Override
public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
List<SimpleGrantedAuthority> roles = null;
DAOUser user = userDao.findByUsername(username);
if (user != null) {
roles = Arrays.asList(new SimpleGrantedAuthority(user.getRole()));
return new User(user.getUsername(), user.getPassword(), roles);
}
throw new UsernameNotFoundException("User not found with the name " + username); }
public DAOUser save(UserDTO user) {
DAOUser newUser = new DAOUser();
newUser.setUsername(user.getUsername());
newUser.setPassword(bcryptEncoder.encode(user.getPassword()));
newUser.setRole(user.getRole());
return userDao.save(newUser);
}
}
#Service
public class JwtUtil {
private String secret;
private int jwtExpirationInMs;
private int refreshExpirationDateInMs;
#Value("${jwt.secret}")
public void setSecret(String secret) {
this.secret = secret;
}
#Value("${jwt.expirationDateInMs}")
public void setJwtExpirationInMs(int jwtExpirationInMs) {
this.jwtExpirationInMs = jwtExpirationInMs;
}
#Value("${jwt.refreshExpirationDateInMs}")
public void setRefreshExpirationDateInMs(int refreshExpirationDateInMs) {
this.refreshExpirationDateInMs = refreshExpirationDateInMs;
}
private Session session ;
public Map<String, String> generateToken(UserDetails userDetails) {
Map<String, Object> claims = new HashMap<>();
Collection<? extends GrantedAuthority> roles = userDetails.getAuthorities();
if (roles.contains(new SimpleGrantedAuthority("ROLE_ADMIN"))) {
claims.put("isAdmin", true);
}
if (roles.contains(new SimpleGrantedAuthority("ROLE_USER"))) {
claims.put("isUser", true);
}
Map<String, String> tokens = new HashMap<>();
String AccessToken = doGenerateToken(claims, userDetails.getUsername());
String RefreshToken = doGenerateRefreshToken(claims, userDetails.getUsername()) ;
tokens.put("AccessToken", AccessToken);
tokens.put("RefreshToken", RefreshToken);
return tokens;
}
private String doGenerateToken(Map<String, Object> claims, String subject) {
return Jwts.builder().setClaims(claims).setSubject(subject).setIssuedAt(new Date(System.currentTimeMillis()))
.setExpiration(new Date(System.currentTimeMillis() + jwtExpirationInMs))
.signWith(SignatureAlgorithm.HS512, secret).compact();
}
public String doGenerateRefreshToken(Map<String, Object> claims, String subject) {
return Jwts.builder().setClaims(claims).setSubject(subject).setIssuedAt(new Date(System.currentTimeMillis()))
.setExpiration(new Date(System.currentTimeMillis() + refreshExpirationDateInMs))
.signWith(SignatureAlgorithm.HS512, secret).compact();
}
public boolean validateToken(String authToken) {
try {
Jws<Claims> claims = Jwts.parser().setSigningKey(secret).parseClaimsJws(authToken);
return true;
} catch (SignatureException | MalformedJwtException | UnsupportedJwtException | IllegalArgumentException ex) {
throw new BadCredentialsException("INVALID_CREDENTIALS", ex);
} catch (ExpiredJwtException ex) {
throw ex;
}
}
public String getUsernameFromToken(String token) {
Claims claims = Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody();
return claims.getSubject();
}
public List<SimpleGrantedAuthority> getRolesFromToken(String token) {
Claims claims = Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody();
List<SimpleGrantedAuthority> roles = null;
Boolean isAdmin = claims.get("isAdmin", Boolean.class);
Boolean isUser = claims.get("isUser", Boolean.class);
if (isAdmin != null && isAdmin) {
roles = Arrays.asList(new SimpleGrantedAuthority("ROLE_ADMIN"));
}
if (isUser != null && isAdmin) {
roles = Arrays.asList(new SimpleGrantedAuthority("ROLE_USER"));
}
return roles;
}
}
#RestController
public class AuthenticationController {
#Autowired
private AuthenticationManager authenticationManager;
#Autowired
private CustomUserDetailsService userDetailsService;
#Autowired
private JwtUtil jwtUtil;
#RequestMapping(value = "/authenticate", method = RequestMethod.POST)
public ResponseEntity<?> createAuthenticationToken(#RequestBody AuthenticationRequest authenticationRequest , TokensRepo tokensRepo)
throws Exception {
try {
authenticationManager.authenticate(new UsernamePasswordAuthenticationToken(
authenticationRequest.getUsername(), authenticationRequest.getPassword()));
} catch (DisabledException e) {
throw new Exception("USER_DISABLED", e);
}
catch (BadCredentialsException e) {
throw new Exception("INVALID_CREDENTIALS", e);
}
UserDetails userdetails = userDetailsService.loadUserByUsername(authenticationRequest.getUsername());
Map<String, String> token = jwtUtil.generateToken(userdetails);;
Session newSession = new Session();
newSession.setTokens(token);
newSession.setSession_date(new Date());
return ResponseEntity.ok(token);
}
#RequestMapping(value = "/register", method = RequestMethod.POST)
public ResponseEntity<?> saveUser(#RequestBody UserDTO user) throws Exception {
return ResponseEntity.ok(userDetailsService.save(user));
}
public Map<String, Object> getMapFromIoJsonwebtokenClaims(DefaultClaims claims) {
Map<String, Object> expectedMap = new HashMap<String, Object>();
for (Entry<String, Object> entry : claims.entrySet()) {
expectedMap.put(entry.getKey(), entry.getValue());
}
return expectedMap;
}
}
When i tested the /authenticate api i got the access tokens and the refresh token
but when i tried to use one of them i got this error

I have seen similar questions but I could not fix my problem.
I have 2 microservices User and Account.
I am trying to send a POST request to add user -
It should add user to the list which I have in UserServiceImpl which you can see below and send a post request to Account-Service that adds an account to the accountList.
Code is attached below for user service -
User Entity (User.java)
public class User {
public Integer userId;
private String name;
private String email;
private Account account;
Account Entity (Account.java)
public class Account {
private Integer accNo;
private Integer accountBalance;
private Integer userId;
All getters setters etc not shown but its there.
My User Service -
#Service
public class UserServiceImpl implements UserService{
#Autowired
RestTemplate restTemplate;
ArrayList<User> userList = new ArrayList<User>(
Arrays.asList(
new User(1311, "Vaibhav Shrivastava", "innomightmail#gmail.com"),
new User(1312, "Varun Shrivastava", "varun#gmail.com"),
new User(1313, "Rajesh Shrivastava", "rajesh#gmail.com"))
);
#Override
public User getUser(Integer id) {
// TODO Auto-generated method stub
System.out.println(this.userList.stream().filter(user -> user.getUserId().equals(id)).findAny().orElse(null));
return this.userList.stream().filter(user -> user.getUserId().equals(id)).findAny().orElse(null);
}
#Override
public List<User> getAllUsers() {
// TODO Auto-generated method stub
return userList;
}
#Override
public <T> ResponseEntity<User> addUser(User user) {
// TODO Auto-generated method stub
userList.add(user);
Account newAccount = new Account(1004, 0, 1314);
this.restTemplate.postForObject("http://account-service/account/add-account/", newAccount, Account.class);
return new ResponseEntity<User>((User)user, HttpStatus.OK);
}
User Controller (UserController.java)
#RestController
#RequestMapping("/user")
public class UserController {
#Autowired
private UserService userService;
#Autowired
private RestTemplate restTemplate;
#GetMapping("/{userId}")
public User getUser(#PathVariable("userId") Integer userId) {
User user = this.userService.getUser(userId);
Account account = this.restTemplate.getForObject("http://account-service/account/user/" + user.getUserId(), Account.class);
user.setAccount(account);
return user;
}
#GetMapping("/all-users")
public List<User> getAllUsers(){
return this.userService.getAllUsers();
}
#PostMapping("/add-user")
public ResponseEntity<Object> addUser(#RequestBody User user) {
try {
User newUser = new User(user.getUserId(), user.getName(), user.getEmail());
this.userService.addUser(newUser);
return new ResponseEntity<>(user, HttpStatus.CREATED);
} catch (Exception e) {
return new ResponseEntity<>(e, HttpStatus.INTERNAL_SERVER_ERROR);
}
}
add account api on Account service is working fine on its own.
When I send post request to add user, it adds user but it does not create account and gives the error -
aborted could not get response in postman and you can see the log.
I want to send a post request on add-user api which will create user and adds it to userList and sends a post request to account service add-account api which creates account and adds to Account List.

Spring-Data-Rest with RoutingDatasource not working because of ResourceMetadataHandlerMethodArgumentResolver throw null pointer

I have one primary database (host) and multiple customer databases (tenant databases) in my application. Configurations are as follows-
Host Database
#EnableTransactionManagement
#EnableJpaRepositories(
basePackages = {"com.sample.dbms.host"},
entityManagerFactoryRef = "hostEntityManagerFactory",
transactionManagerRef = "hostTransactionManager")
public class HostDatabaseConfig {
#Primary
#Bean(name = "hostDataSource")
#ConfigurationProperties(prefix="spring.datasource")
public DataSource hostDataSource() {
return DataSourceBuilder.create().build();
}
#Primary
#Bean(name = "hostEntityManagerFactory")
public LocalContainerEntityManagerFactoryBean hostEntityManagerFactory(EntityManagerFactoryBuilder builder,
#Qualifier("hostDataSource") DataSource dataSource) {
return builder
.dataSource(dataSource)
.packages("com.sample.dbms.host")
.build();
}
#Bean
public PlatformTransactionManager hostTransactionManager(#Qualifier("hostEntityManagerFactory") EntityManagerFactory emf) {
return new JpaTransactionManager(emf);
}
}
Tenant Database
#EnableTransactionManagement
#EnableJpaRepositories(
basePackages = {"com.sample.dbms.ebo"}
)
public class TenantDatabaseConfig {
#Bean(name = "dataSource")
public DataSource dataSource(ApplicationContext context) {
return context.getBean(TenantRoutingDatasource.class);
}
#Primary
#Bean(name = "entityManagerFactory")
public LocalContainerEntityManagerFactoryBean entityManagerFactory(EntityManagerFactoryBuilder builder,
#Qualifier("dataSource") DataSource dataSource) {
return builder
.dataSource(dataSource)
.packages("com.sample.dbms.ebo")
.build();
}
#Bean(name = "transactionManager")
public PlatformTransactionManager transactionManager(#Qualifier("entityManagerFactory") EntityManagerFactory emf) {
return new JpaTransactionManager(emf);
}
}
TenantRoutingDatasource
#Component
public class TenantRoutingDatasource extends AbstractRoutingDataSource {
String migrationPath = "classpath:db";
List<String> migrationFolders = Arrays.asList("table", "index", "proc", "seed");
private final TenantRepository tenantRepository;
private final DataSource hostDataSource;
public TenantRoutingDatasource(TenantRepository tenantRepository,
#Qualifier("hostDataSource") DataSource hostDataSource) {
this.tenantRepository = tenantRepository;
this.hostDataSource = hostDataSource;
Map<Tenant, DataSource> dataSources = new HashMap<>();
Map<Object,Object> tenantMap = new HashMap<>();
tenantRepository.findAllByIsActive(true).forEach(ebo -> {
HikariDataSource dataSource = new HikariDataSource();
dataSource.setDriverClassName(ebo.getDriverClassName());
dataSource.setJdbcUrl(ebo.getJdbcUrl());
dataSource.setUsername(ebo.getUsername());
dataSource.setPassword(ebo.getPassword());
dataSource.setMaximumPoolSize(10);
dataSource.setPoolName("pool_"+ebo.getId());
tenantMap.put(ebo.getId(), dataSource);
dataSources.put(ebo, dataSource);
});
setTargetDataSources(tenantMap);
}
#Override
protected Object determineCurrentLookupKey() {
return TenantHolder.getTenant() == null ? 1 : TenantHolder.getTenant();
}
}
Where TenantRepository is JPA Repository which belongs to the host database.
Which this type of configuration I was trying to use Spring-data-rest but unfortunately when I make the repository as #RestResource and try to hit the URL from postman I got 500 response.
When I debug it then I got the flowing error.

What I understand is that I have some null values in the columns of DB and I am trying to update them. Is there something I am missing? Could someone me help in this regard? Any help will be much appreciated. Thanks

Have you tried this?
TransferDetails td = users.getTransferDetails();
if(td != null) {
TransferDetails _td = _users.getTransferDetails();
if(_td != null) {
_td.setTransferCurrency(td.getTransferCurrency());
} else {
_td = new TransferDetails();
_td.setTransferCurrency(td.getTransferCurrency());
_users.setTransferDetails(_td);
}
}

By reading the code, I see _users.getTransferDetails(). is null. Because, the logger above didn't throw null pointer exception where you're printing users.getTransferDetails().
Set value of TransferDetails only when it is not null like:
// You need to check if the
// `_user.getTransferDetails` is not null,
// then only you can call `setTransferCurrency` of that object.
// Otherwise you'll end up with a NullPointerException.
if(_users.getTransferDetails() !=null)
_users.getTransferDetails().setTransferCurrency(users.getTransferDetails().getTransferCurrency());

I am trying to reach registration page but i am receiving 500 error. the error is about the service layer class epically the save method

What i am trying to do is, when i click on create a user from the login page, it should direct me to the registration form, but it doesn't and i don't see any mistakes. can you please help me?
inside my code:
so I have passed the /registration path in the spring security configure class so I can access this request.
in the UserRegistrationController,
In the Get request, I create the modelAttribute name is "user" and its value is creating an object from UserRegistrationDto and this method showcreateUserForm will return the registration.html
and then in the post request, i passed registrationDto object parameter , and then in the implementation i did >> userService.save(registrationDto);
note :
i tried to see the request without the tag and the page opened so the problem is with the form tags.
the problem is in the Save function in the UserServiceImp, especially the passing role parameter.

I am trying to reach page and I am receiving 500 error

What I am trying to do is, when I click on create a user from the login page, it should direct me to the registration form, but it doesn't and I don't see any mistakes. Can you please help me?
Inside my code I have passed the /registration path in the Spring Security configure class so I can access this request.
In the UserRegistrationController, in the GET request, I create the modelAttribute name is "user" and its value is creating an object from UserRegistrationDto and this method showcreateUserForm will return the registration.html
Then in the POST request, I passed registrationDto object parameter, and then in the implementation I did userService.save(registrationDto);
Note: I tried to see the request without the tag and the page opened so the problem is with the form tags.
The problem is in the Save function in the UserServiceImp, especially the passing role parameter.
My Users class Entity:
#Entity
#Table(name = "users" ,uniqueConstraints = #UniqueConstraint(columnNames = "userName"))
public class Users {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
private String userName;
private String password;
#ManyToMany(fetch = FetchType.EAGER, cascade = CascadeType.ALL)
#JoinTable(
name = "users_roles",
joinColumns = #JoinColumn(
name = "user_id",referencedColumnName ="id"),
inverseJoinColumns = #JoinColumn(
name ="role_id" ,referencedColumnName ="id"
)
)
private Collection<Roles> roles;
public Users(String userName, String password, Collection<Roles> roles) {
this.userName = userName;
this.password = password;
this.roles = roles;
}
public Users()

return "Users{" +
"id=" + id +

}
}
UserRegistrationDto class: this class I will use as a modelAttribute
public class UserRegistrationDto {
private String userName;
private String password;
private Collection<Roles> role;
