when I put debug point below line that define in my service class

I get every value but id variable return id=-1
when I put debug point below line that define in my controller class
return organizationService.updateOrganization(id, organization)
I get same result as above .What is the reason for such type of exception.I never handle any exception ,By default exception handling occurs.

java.util.NoSuchElementException: No value present
at java.base/java.util.Optional.get(Optional.java:141) ~[na:na]
meaning you have invoked Option.get() but the value is null.
You didn't check isPresent() before this line
val address:Address = addressRepository.findById(organization.address.id).get()

I`m trying to learn Spring Boot but am having trouble with Rest API. i'm having a problem with creating restcontroller for my application. I'm trying to read data from database. It works fine when i use commandLineRunner inside main application class. While generating http request this error ocures:

You have a null pointer at line 29, which I guess is the call to the repository, this means that your repository is not injected in the controller. This happens because you haven't allowed spring to inject it. Either make it final and add a constructor that will set it:
#RestController
public class MessageController {
private final CustomerRepository repository;
public MessageController(CustomerRepository repository) {
this.repository = repository;
}
...
Or add #Autowired on the repository field.
#Autowired
CustomerRepository repository;
First option is preferred as you can easily mock the repository in tests and doesn't use reflection to inject the fields.
You are sending an empty array list
#GetMapping(value = "/send")
public List<CustomerUI> findAll(){
List<Customer> customers = repository.findAll();
List<CustomerUI> customerUI = new ArrayList<>();
for (Customer customer : customers) {
System.out.println(customer.toString());
}
return customers;
}

org.springframework.expression.spel.SpelEvaluationException: EL1008E: Property or field 'fastPassId' cannot be found on object of type 'byte[]'

I am following video series from here: https://app.pluralsight.com/course-player?clipId=5133b583-6d21-4f49-b069-95f5ae7a60d8 and last section is not quite working well for me. The only thing I changed is I'm using latest version of Spring Boot 2.7.0.

System.out.println("fastpassid: " + fastpassid);

System.out.println("Customer : "+ customer);
//send message to stream endpoint first
streamBridge.send("generatetollcharge-out-0", new FastPassToll(fastpassid, "1000", 1.05f)); //line-35
//return view name
return "console";
}
}
Almost the code is same
I can't see what's on the video, since i need to sign up but based on the stack trace it appears you are trying to use SpEL on the payload which exists in its raw format byte[]. That is about as much as I can say since I don't have a view into the application.
Consider creating a small sample in Github so we can clone and take a look to avoid the guessing game.

Getting An exception While following a tutorial

I was following this tutorial: https://www.youtube.com/watch?v=BazFP71ju28&list=PLXy8DQl3058OoJqGLFdqoBkBKm2T0kS9B&index=2&ab_channel=LiliumCode & https://www.youtube.com/watch?v=3xloj8KtI8k&list=PLXy8DQl3058OoJqGLFdqoBkBKm2T0kS9B&index=3
In the first video, he creates a person index using annotations instead of creating a json file with the mappings which he does (to create vehicle index) in this part. After that he implements search feature on the vehicle index and says it can be similarly be implemented for the person index. I tried it out but am getting an exception:

I am attaching the changes/functions I created to make the search:
PersonService.java:
#Service
public class PersonService {
private static final ObjectMapper MAPPER = new ObjectMapper();
private static final Logger LOG = LoggerFactory.getLogger(PersonService.class);
private final RestHighLevelClient client;
private final PersonRepository repository;
#Autowired
public PersonService(PersonRepository repository, RestHighLevelClient client) {
this.repository = repository;
this.client = client;
}
//save function
//findById function
public List<Person> search(final SearchRequestDTO dto) {
final SearchRequest request = SearchUtil.buildSearchRequest(Indices.PERSON_INDEX, dto);
if (request == null) {
LOG.error("Failed to build search request");
return Collections.emptyList();
}
try {
final SearchResponse response = client.search(request, RequestOptions.DEFAULT);
final SearchHit[] searchHits = response.getHits().getHits();
final List<Person> persons = new ArrayList<>(searchHits.length);
for (SearchHit hit : searchHits) {
persons.add(
MAPPER.readValue(hit.getSourceAsString(), Person.class)
);
}
return persons;
} catch (Exception e) {
LOG.error(e.getMessage(), e);
return Collections.emptyList();
}
}
}
Endpoint for search in PersonController.java:
#PostMapping("/search")
public List<Person> search(#RequestBody final SearchRequestDTO dto) {
return service.search(dto);
}
Search request through postman:
Proof that 'Jason' exists
The rest of the files (SearchDTO, SearchUtil etc are same as in the videos mentioned above) and the full project can be found at: https://github.com/SiDMerceR1/ES_Test/tree/main/elasticsearch
Versions:
Spring Boot: 2.6.4
Spring Data ES: 4.3.2
ES: 7.17.1
Please help me figure out how to deal with this exception. Thank you.
So I looked at the documentation as suggested by #P.J.Meisch and found this solution:
Defined this method in PersonRepository:
List<Person> findByName(String name);
Defined this in the PersonService:
public List<Person> search(final SearchRequestDTO dto) {
return repository.findByName(dto.getSearchTerm());
}
And now I am getting the result:
Please let me know if this is the correct way to do this.

findByName using Join in JPA #Query

MovieCatalogue contains 2 fields of type MovieData and Rating(let's ignore this for now) respectively,
MovieData contains "String name", "String description" and a JoinColumn for MovieCatalogue.
From table of MovieCatalogue, i want to get Movies by name from table MovieData. For which i join tables of MovieCatalogue and MovieData, compare where primary key = foreign key, i want to get movie name
Kindly guide me what am i missing?
I am getting
ERROR: more than one row returned by a subquery used as an expression
I want to get List of MovieCatalogues where MovieData.name match the queried name.

Here is my function to find the teacher name who teaches Math.
#GetMapping("/exisingMath")
fun getMathTeacher():List<Teacher>{
val existingMath:MutableList<Teacher> = ArrayList(teachRopo.mathTeacher())
existingMath.forEach { e -> println(e) }
return existingMath
}
Define above function in my TeacherController Class
TeacherRepository Class
package com.nilmani.jpqlprojectexample.repository
import com.nilmani.jpqlprojectexample.entity.Teacher
import org.springframework.data.jpa.repository.JpaRepository
import org.springframework.data.jpa.repository.Query
import org.springframework.data.repository.query.Param
interface TeacherRepository : JpaRepository<Teacher,Long> {
#Query("select t.nameOfTeacher from Teacher t where t.subject=1")
fun mathTeacher():List<Teacher>
}
TeacherEntity Class
package com.nilmani.jpqlprojectexample.entity
import com.nilmani.jpqlprojectexample.enum.Subject
import com.nilmani.jpqlprojectexample.enum.University
import javax.persistence.Entity
import javax.persistence.GeneratedValue
import javax.persistence.GenerationType
import javax.persistence.Id
#Entity
data class Teacher(
#Id
#GeneratedValue(strategy = GenerationType.AUTO)
val id:Long=-1,
val nameOfTeacher:String="",
val price:Long=-1,
val subject:Int=Subject.MATH.type,
val university:Int=University.OTHER.type
)
I am using IntelliJ IDEA ultimate2021.1 version as code editor,Mac as os
Can you please try if this helps?
change
#Query("select t.nameOfTeacher from Teacher t where t.subject=1")
Into:
#Query("select t from Teacher t where t.subject=1")
