I am going to be upfront, I am a newb in Java, especially with SpringBoot. I've been aping the Vaadin CRM tutorial application with minor custormization for my needs.
When I try to login, it throws the following error, which I cannot figure out, so again, I am just going to copypaste the entire stacktrace:
There was an exception while trying to navigate to '' with the exception message 'Error creating bean with name 'listView' defined in file [C:\Users\nikol\Desktop\vaadin-crm\vaadin-crm\target\classes\com\vaadin\tutorial\crm\UI\views\list\ListView.class]: Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.vaadin.tutorial.crm.UI.views.list.ListView]: Constructor threw exception; nested exception is java.lang.IllegalStateException: Property type 'java.lang.Integer' doesn't match the field type 'java.lang.String'.

Hopefully, you'll tell me how line 63 and 44 are related and what's bugging them, because this particular code monkey is stumped.
The issue is that form1 isn't initialized when you try to add it on line 62.

}
String uuidFile = UUID.randomUUID().toString();
String resultFilename = uuidFile + "." + file.getOriginalFilename();
file.transferTo(new File(uploadPath + "/" + resultFilename));
message.setFileName(resultFilename);
}
}
}
Controller(Rest api):
#PreAuthorize("hasAuthority('user:write')")
#ApiOperation(value = "Saving the message to the database with the data from request body")
#PostMapping(value = "",consumes = MediaType.ALL_VALUE)
public ResponseEntity<MessageSaveResponse> saveMessage(#AuthenticationPrincipal SecurityUser user,
#RequestBody MessageRequest messageRequest,
#RequestParam("file") MultipartFile file) throws IOException {
Message message = messageService.saveMessage(messageRequest, user,file);
MessageSaveResponse messageResponse = messageMap.messageToMessageSaveResponse(message);
return new ResponseEntity<>(messageResponse, HttpStatus.CREATED);
}
Then i try to send request in postman with the file param an body of the message:
And the status is 415 Unsupported Media Type,it works great without the file but i need to attach it to the message

I'm using Vaadin and Spring Boot to build webapp used as registration form.
I'm getting an issue when deploying the webapp inside a Tomcat (but never when lauching directly from Intellij IDE).
The Stacktrace is :

With some research on this error I added the annotation #Autowired and #Qualifier to OktaService construction but did not change anything.
Thank you !
One potential problem could be with your Java package structure. Spring Boot does by default only look for annotated within the Java package (and it's children) that contains the Application class.
If your OktaService is in a location of your package structure, then it won't be found by default. As an example, if you have Application in com.example.myapp.ui and OktaService in com.example.myapp.service, then it won't work. If this is the case, then you can either change your package structure or set the scanBasePackages property in #SpringBootApplication to define a location that covers the entire application.
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"
Error:
Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.NullPointerException] with root cause
java.lang.NullPointerException: null

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;

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.

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
