#query annotation doesn't work with hibernate-ogm and mongodb in spring boot

#query annotation doesn't work with hibernate-ogm and mongodb in spring boot - mongodb

I wrote a Spring boot,hibernate orm application using mysql database.... But now I want to switch to mongodb... I used Hibernate-ogm for fulfill my requirement. When run the application the console shows successfully switch to mongodb using hibernate-ogm... But the query is not working... I import below packages for my repository to hibernate-orm and these imports works fine with mysql... But in hibernate-ogm #query annotation doesn't work...
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.data.jpa.repository.Query;
This is my model
#Entity
#Indexed
public class User {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;
private String nic;
private String emp;
private String firstName;
private String lastName;
#NotEmpty

Postgresql jsonb doesn't work with Spring Data JPA

I tried to save into a jsonb column but I didn't find any solution of my problem.
Postgresql 15.

With the following TemplateFullConverter class

} catch (SQLException | JsonProcessingException e) {

return po;

this.role = role;
}
public User() {
super();
}
}
I tried to use PostMan and did the following setting, but couldnt reach the UserController. The result from Postman is always 404, NOT FOUND.

Add the annotation #RequestMapping("/") also on class level since Spring requires a mapping for your class also, not only the method.
#RestController
#RequestMapping("/")
public class UserController {
Also you have
#RequestParam("name") String name, #RequestParam("role") String role
but in Postman you pass name and role in JSON body. It is not coded to work like this. You should pass name and role as query parameters in Postman.

#RestController
#RequestMapping("/")
public class UserController {
#Autowired
MongoService db;
#PostMapping("/create")
public User createNew(#RequestParam("name") String name, #RequestParam("role") String role){
User obj = new User(name, role);
User newObj = db.save(obj);
return newObj;
}
}
it is better to use swagger you can get endpoints easily.

Issue :
As per the User entity class , #Id is manually generated.
(I have a CSV file which has Id field which is read in User entity)
So Id is not auto generated
Whenever I call this.userJpaRepository.saveAll(users) and even when there is an User entity with Id already existing , the User entity gets overwritten.
That is , Id with same entity gets overwritten with new data.
It has to throw - Unique index or primary key violation error
However, when I try to insert duplicate entry into H2 database MANUALLY , it throws exception - Unique index or primary key violation
I also tried adding unique=true to Id field in User Entity but its not working
Can anybody please help on resolving this issue please ?

Well as it turns out that the behavior that you are seeing is because of the call to em.merge(...) in the save() implementation. Here is what actually happens:
#Transactional
#Override
public <S extends T> S save(S entity) {
Assert.notNull(entity, "Entity must not be null.");
if (entityInformation.isNew(entity)) {
em.persist(entity);
return entity;
} else {
return em.merge(entity); // Update if the entity is not new
}
}
This is a sample code from SimpleJpaRepository implementation. you can use your own query methods for updating the existing query something like this:
#Modifying
#Query("update User u set u.firstname = ?1 where u.lastname = ?2")
int setFixedFirstnameFor(String firstname, String lastname);

Map domain class to DTO class using Mapstruct and lombok in SpringBoot application with RestController

The below is my main application class.
#SpringBootApplication
#EnableAutoConfiguration
#ComponentScan("com.example.demo")
public class Demo1Application {
public static void main(String[] args) {
SpringApplication.run(Demo1Application.class, args);
}
}
Controller Class.
#RestController
public class JobAppController {
#Autowired
JobApplicationRepository jobApplicationRepository;
//#Autowired
//private JobApplicationMapper mapper;
JobApplicationMapper mapper = Mappers.getMapper(JobApplicationMapper.class);
#GetMapping("/hello")
public String greeting()
{
return "hello Mr";
}
#PostMapping("/save")
public JobApplicationDto save(#RequestBody JobApplicationDto jobApplicationDto)
{
JobApplication jobApplication = mapper.toEntity(jobApplicationDto);
jobApplication = jobApplicationRepository.save(jobApplication);
return mapper.ToDTO(jobApplication);
}
}
Mapper Interface.
#Mapper
#Component
public interface JobApplicationMapper {
//JobApplicationMapper mapper = Mappers.getMapper(JobApplicationMapper.class);
//({ #Mapping(target="employeeId", source="entity.id"),#Mapping(target="employeeName", source="entity.name")})
JobApplicationDto ToDTO(JobApplication jobApplication);
JobApplication toEntity(JobApplicationDto jobApplicationDto);
}

when try to post data/dto (as JSON) into my db table through postman, the data gets inserted as null values
{

"company" : "softInc",
"current_status" : "under review",
"position" : "SE3",
"location" : "Himalayas"
}
the response after insertion is like so
{
"id": null,
"requisition_id": null,
"job_posting_source": null,
"applied_date": null,
"company": null,
"current_status": null,
"position": null,
"location": null
}
There is no error message. not sure what I am missing.
After thorough debug, I realized that there is no issue with the mapper implementation. however since I am using "lombok" for the domain and the dto classes, the getters and setters weren't being generated. So I manually added them now in the code and works as expected now.
PS: I would rate my self as a beginner with this, so any kind of discussion/suggestions are welcome.
I would edit the question now, as the issue is with lombok as to why the getters/setters aren't being generated.

I guess Lombok is missing as annotation processor..
Try:
<annotationProcessorPaths>
<path>
<groupId>org.mapstruct</groupId>
<artifactId>mapstruct-processor</artifactId>
<version>${org.mapstruct.version}</version>
</path>
<path>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>${org.projectlombok.version}</version>
</path>
</annotationProcessorPaths>
Checkout this for a working example.
Please note: there are several issues with Lombok / MapStruct. Both are annotation processors. Lombok generates getters / setters, MapStruct uses them. Timing is essential. Hence, MapStruct introduced an SPI to signify when generation is ready.
