AmazonS3 variable is not getting autowired correctly - java

I am trying to run a Spring Application which works with AmazonS3 but the amazonS3 variable in AmazonS3Abstraction.java is not getting autowired correctly for some reason. It stays null. It keeps throwing an SDK Client Exception: Unable to load AWS Credentials from any provider in the chain.
I want the variable amazonS3 in AmazonS3Abstraction.java to have the exact same value which is getting returned by the bean, initializaAmazonS3(), in ApplicationConfiguration.java.
I am attaching my code and stack trace below. Please help me out. Feel free to add for more details.

You might want to try by giving the bean name as "amazonS3". This seems to be an issue.
#Bean
public AmazonS3 initializeAmazonS3(){
Second, you don't have to create an S3 client bean yourself. Having Spring Cloud AWS on the classpath and providing AWS configurations will auto-create the client for you.
Refer to this section Configurating Credentials

Cannot handle ConstraintViolationException for Cross-Parameter Constraints/Validations

I have gone through many post related to ConstraintViolationException on StackOverflow but couldn't get any help. I am using Spring Boot v2.3.3 web application with spring-boot-starter-validation. I want to validate a password using a custom annotation for Cross-Parameter Constraints. In order to do that, I have followed this Baeldung link. Below is the implementation class which inherits ConstraintValidator:
#SupportedValidationTarget(PARAMETERS)
public class ValidPasswordValidator implements ConstraintValidator<ValidPassword, Object[]> {
private ValidateRequestTypeEnum requestType;
#Autowired
private PasswordValidatorService passwordValidatorService;
#Override
public void initialize(ValidPassword constraintAnnotation) {
this.requestType = constraintAnnotation.requestType();
SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this);
}
#Override
public boolean isValid(Object[] value, ConstraintValidatorContext context) {
SomeUser someUser = (SomeUser) value[0];
try {
passwordValidatorService.validate(someUser, this.requestType);
} catch (ConstraintViolationException e) {
context.disableDefaultConstraintViolation();
context.buildConstraintViolationWithTemplate(e.getMessage()).addConstraintViolation();
return false; // If this is turned true then no exception is thrown
}
return true;
}
}
Now whenever I return false in the isValid() method, I get the ConstraintViolationException, even after handling it in the catch block. The behaviour remains the same even if I throw a different Exception and handle it in the catch block.
Below are my other class implementaions and stacktrace. Any help will be greatly appreciated.
ValidPassword Annotation:
#Constraint(validatedBy = ValidPasswordValidator.class)
#Target({METHOD, CONSTRUCTOR})
#Retention(RUNTIME)
#Documented
public #interface ValidPassword {
String message() default "";
ValidateRequestTypeEnum requestType();
Class<?>[] groups() default {};
Class<? extends Payload>[] payload() default {};
}
Controller class:
#Validated
#RestController
public class SomeController {
#ValidPassword(requestType = CREATE_USER)
#GetMapping("/create-user")
public void createUser(#RequestBody SomeUser someUser) {
System.out.println("Create User Mapping");
System.out.println(someUser.toString());
}
}
SomeUser Model class:
public class SomeUser {
private int id;
private String name;
private String password;
// getters and setters abbreviated
// toString() abbreviated
}
PasswordValidatorService:
public interface PasswordValidatorService {
void validate(SomeUser someUser, ValidateRequestTypeEnum requestType) throws ConstraintViolationException;
}
PasswordLengthValidatorImpl:
#Service
public class PasswordLengthValidatorImpl implements PasswordValidatorService {
#Override
public void validate(SomeUser someUser, ValidateRequestTypeEnum requestType) throws ConstraintViolationException {
switch (requestType) {
case CREATE_USER:
System.out.println("From Create_User block");
if (someUser.getPassword().length() < 8) {
throw new ConstraintViolationException("Password length less than 8", new HashSet<>());
}
break;
default:
System.out.println("---Default switch block---");
}
}
}
Stacktrace:
javax.validation.ConstraintViolationException: createUser.<cross-parameter>: Password length less than 8

Now whenever I return false in the isValid() method, I get the
ConstraintViolationException, even after handling it in the catch
block. The behaviour remains the same even if I throw a different
Exception and handle it in the catch block.
You can actually try this out in an IDE debugger ( like eclipse) and follow the validation path.
The isValid method of ConstraintValidator is a contract between validation engine and your constraint validation logic. If it fails it has to return false.
The actual code that handles it is in org.hibernate.validator.internal.engine.constraintvalidation.ConstraintTree
The stack trace you are seeing is not what you have thrown and caught - rather it's internally generated in org.springframework.validation.beanvalidation.MethodValidationInterceptor

I am getting below error while creating spring maven rest webservice. It works fine when i use postman to test post request on the api for ocbc. But when i tried to do post request for citi, i got the following error: Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.NullPointerException] with root cause. And in my postman it shows error: "Internal Server Error", Status :"500"

}
}
Please advise what is wrong in my code. Thanks in advance.
Also can i ask if there any recommendation ways to encrypt the data value obtained from api before added into the database.
You need to add #Autowired to bankCitiBankDAO too:
#Autowired
private BankOCBCDAO bankOCBCDAO;
#Autowired
private BankCitiBankDAO bankCitiBankDAO;
But as field injection is not the best thing todo (https://www.vojtechruzicka.com/field-dependency-injection-considered-harmful/), you should go with constructor injection:
#Service
public class PaymentServiceImpl implements PaymentService{
private BankOCBCDAO bankOCBCDAO;
private BankCitiBankDAO bankCitiBankDAO;
public PaymentServiceImpl(BankOCBCDAO bankOCBCDAO, BankCitiBankDAO bankCitiBankDAO){
this.bankOCBCDAO = bankOCBCDAO;
this.bankCitiBankDAO = bankCitiBankDAO;
}
...
}
Please add the Proper Annotations in Model Class
that will clear the issues.
Reference
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name="bank_id")
private int bankId;

‘Authentication object cannot be null’ error when query method is performed in open endpoint

I have public method checkProfileToken in AuthenticationController that grabs some information from the Neo4j database using the Neo4jRepository implementation - ProfileRepository.
I’ve ignored Spring Security for this request /check_profiletoken in OAuth2SecurityConfiguration class:
#Configuration
#EnableWebSecurity
public class OAuth2SecurityConfiguration extends WebSecurityConfigurerAdapter {
// …
#Override
public void configure(WebSecurity webSecurity) {
webSecurity.ignoring().antMatchers("/check_profiletoken"); // ingoring WebSecurity for this entry
}
// …
}
Controller (AuthenticationController.java):
#RestController
public class AuthenticationController {
#Autowired
ProfileRepository profileRepository;
// …
#RequestMapping(method = RequestMethod.POST, value = "/check_profiletoken")
public ResponseEntity<?> checkProfileToken(#RequestBody final JSONObject jsonRequest) {
// HTTP response container
HttpHeaders responseHeaders = new HttpHeaders();
responseHeaders.setLocation(ServletUriComponentsBuilder.fromCurrentRequest().buildAndExpand().toUri());
final String token = (String) jsonRequest.get("token");
Integer tokenType = null;
try {
tokenType = (Integer) jsonRequest.get("tokentype");
} catch (Exception e) {
return new ResponseEntity<>(
new ActionResponseDTO(
new ActionResponseItemDTO(ActionResponseTypes.ERROR, ActionResponseCodes.INVALID_DATA,
ActionResponseDomains.PROFILE_TOKEN, null, "Token type is invalid!")),
null, HttpStatus.BAD_REQUEST);
}
ActionResponseDTO actionResponses = commonService.checkProfileToken(token,
ProfileTokenType.getByCode(tokenType));
if (actionResponses.isValid()) {
return new ResponseEntity<>(actionResponses, responseHeaders, HttpStatus.OK);
} else {
return new ResponseEntity<>(actionResponses, responseHeaders, HttpStatus.BAD_REQUEST);
}
}
// …
}
In method checkProfileToken I call getProfileForActivation query method of the ProfileRepository
Repository (ProfileRepository.java):
#Repository
public interface ProfileRepository extends Neo4jRepository<Profile, String> {
// …
#Query("MATCH (p:Profile)-[r:HAS_PARENT]->(g:Group) WHERE p.uuid=$profileId RETURN g.displayName as companyName, p.honorificPrefix as honorificPrefix, p.givenName as givenName, p.familyName as familyName, p.gender as gender")
ProfileActivation getProfileForActivation(#Param("profileId") String profileId);
// …
}
Here is an error that I got when performing query above:

WebSocket Using Spring Integration

I would like to try using Spring Integration Websocket by having a client and server communication. A REST call POST will be sent to the server side which will publish this String name message to the client side through websocket and the client will just print out this name.
As I am new and still trying this out, not sure if I am heading the right way of doing.
This is my code:
Server side
WebSocketConfig
package com.example.websocketserver.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.integration.annotation.IntegrationComponentScan;
import org.springframework.integration.annotation.ServiceActivator;
import org.springframework.integration.channel.DirectChannel;
import org.springframework.integration.config.EnableIntegration;
import org.springframework.integration.websocket.ServerWebSocketContainer;
import org.springframework.integration.websocket.outbound.WebSocketOutboundMessageHandler;
import org.springframework.messaging.MessageChannel;
import org.springframework.messaging.MessageHandler;
#Configuration
#EnableIntegration
#IntegrationComponentScan
public class WebSocketConfig {
#Bean
public IntegrationWebSocketContainer serverWebSocketContainer() {
return new ServerWebSocketContainer("/messages");
}
#Bean
#ServiceActivator(inputChannel = "requestChannel")
public MessageHandler webSocketOutboundMessageHandler() {
return new WebSocketOutboundMessageHandler(serverWebSocketContainer());
}
#Bean
public MessageChannel requestChannel() {
return new DirectChannel();
}
}
Gateway
package com.example.websocketserver.gateway;
import org.springframework.integration.annotation.Gateway;
import org.springframework.integration.annotation.MessagingGateway;
#MessagingGateway
public interface IntegrationGateway {
#Gateway(requestChannel = "requestChannel")
void send(String message);
}
Controller
package com.example.websocketserver.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
import com.example.websocketserver.gateway.IntegrationGateway;
#RestController
public class SendController {
#Autowired
private IntegrationGateway integrationGateway;
#PostMapping("/{name}")
public void send(#PathVariable String name) {
integrationGateway.send(name);
}
}
Client side
WebSocketConfig
package com.example.websocketclient.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.integration.annotation.IntegrationComponentScan;
import org.springframework.integration.channel.DirectChannel;
import org.springframework.integration.config.EnableIntegration;
import org.springframework.integration.websocket.ClientWebSocketContainer;
import org.springframework.integration.websocket.IntegrationWebSocketContainer;
import org.springframework.integration.websocket.inbound.WebSocketInboundChannelAdapter;

import org.springframework.web.socket.client.standard.StandardWebSocketClient;
#Configuration
#EnableIntegration
#IntegrationComponentScan
public class WebSocketConfig {
#Bean
public WebSocketClient webSocketClient() {
return new StandardWebSocketClient();
}
#Bean
public WebSocketInboundChannelAdapter webSocketInboundChannelAdapter() {
WebSocketInboundChannelAdapter webSocketInboundChannelAdapter =
new WebSocketInboundChannelAdapter(clientWebSocketContainer());
webSocketInboundChannelAdapter.setOutputChannel(webSocketInboundChannel());
return webSocketInboundChannelAdapter;
}
#Bean
public IntegrationWebSocketContainer clientWebSocketContainer() {
return new ClientWebSocketContainer(webSocketClient(), "ws://localhost:8001/messages");
}
#Bean
public MessageChannel webSocketInboundChannel() {
return new DirectChannel();
}
}
MessageEndpoint
package com.example.websocketclient.endpoint;
import org.springframework.integration.annotation.MessageEndpoint;
import org.springframework.integration.annotation.ServiceActivator;
import lombok.extern.slf4j.Slf4j;
#MessageEndpoint
#Slf4j
public class WebSocketEndpoint {

I tried running both applications and this is the exception I've gotten in the client side :

When I debug, it looks like userService is not injected successfully
Before I use userMapper, I test it and it works
Change this from ;
#RequestMapping("/getUser")
public String getUserByNameOrEmail(String str) {
return userservice.getUserByNameOrEmail(str).toString();
}
To somthing like this :
#RequestMapping("/getUser/{str}")
public String getUserByNameOrEmail(#PathVariable String str) {
return userservice.getUserByNameOrEmail(str).toString();
}
NullPointerException because "str" was not getting assigned to any value when called and calling toString() on null throws NullPointerException.
Now you can call your endpoint as : /getUser/useroremailidhere
I believe it's giving you NullPointerException because your parameter to that request should not be getting assigned to the argument you've mentioned in the controller. Make sure the parameter that you're passing to the argument through the url should have exact name as the parameter you've mentioned in the UserController class. If you can give the code then I can try running it myself to see what's causing the error
Remove the #Mapper annotation and debug to the controller layer to see if the service is null
