Repository bean not found for service implementation

I'm new in spring boot, I came across this problem where I couldn't run the app TLDR of the error:

Description:

Parameter 0 of constructor in dev.vianneynara.portoapi.service.ProjectServiceImpl required a bean of type 'dev.vianneynara.portoapi.repository.ProjectRepository' that could not be found.


Action:

Consider defining a bean of type 'dev.vianneynara.portoapi.repository.ProjectRepository' in your configuration.

I have tried debugging it, but I couldn't read and solve the problem, as I've reached with copilot to confirm whether or not I did this right, they even said my structure and annotations seem fine.

response from built in copilot, had to ask it

dan1st•8mo ago

How are you running the application (which class are you running, which package is that in etc)? Can you show your application.properties?

circleOP•8mo ago

Here is the application.properties:

spring.application.name=PortoAPI

# DATASOURCE CONFIGURATION
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/portoapi
spring.datasource.username=something
spring.datasource.password=something

spring.application.name=PortoAPI

# DATASOURCE CONFIGURATION
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

spring.datasource.driver-class-name=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/portoapi
spring.datasource.username=something
spring.datasource.password=something

I excluded the database because I haven't used it previously, but commenting the exclusion doesn't affect anything. I run it using .\mvnw spring-boot:run or with -X

circleOP•8mo ago

It looks just fine to me, the PortoApiApplication is the one to run

dan1st•8mo ago

Can you show the stack trace?

circleOP•8mo ago

Do you want me to put it in a log txt?

dan1st•8mo ago

ideally using a codeblock?

circleOP•8mo ago

alright, it might be if u want to debug. Coming. I cut the spring logo part allong with some uh

dan1st•8mo ago

Why do you have the spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration in your application.properties?

circleOP•8mo ago

I didn't use the database It was raising autoconfig on datasource error

dan1st•8mo ago

But you need the repository? Well you can't use a repository without a valid datasource

circleOP•8mo ago

Not yet, I haven't used it. I wanted to now wait... let me check

dan1st•8mo ago

well ProjectServiceImpl requires it so due to the existence of ProjectServiceImpl, you need a valid DataSource

circleOP•8mo ago

I tried many times now, I have also made the database and table... But the error persists on that problem I might've foudn a clue

circleOP•8mo ago

message.txt

circleOP•8mo ago

This is the chained error, which I assume points out to the bottom of the problem

Caused by: org.springframework.data.repository.query.QueryCreationException: Could not create query for public abstract void dev.vianneynara.portoapi.repository.ProjectRepository.updateProjectById(java.lang.Long,dev.vianneynara.portoapi.model.Project); Reason: Failed to create query for method public abstract void dev.vianneynara.portoapi.repository.ProjectRepository.updateProjectById(java.lang.Long,dev.vianneynara.portoapi.model.Project); No property 'updateProjectById' found for type 'Project'

Caused by: org.springframework.data.repository.query.QueryCreationException: Could not create query for public abstract void dev.vianneynara.portoapi.repository.ProjectRepository.updateProjectById(java.lang.Long,dev.vianneynara.portoapi.model.Project); Reason: Failed to create query for method public abstract void dev.vianneynara.portoapi.repository.ProjectRepository.updateProjectById(java.lang.Long,dev.vianneynara.portoapi.model.Project); No property 'updateProjectById' found for type 'Project'

updateProjectById is being used in a method in ProjectServiceImpl

dan1st•8mo ago

What is updateProjectById supposed to be? Why do you think Spring would allow that?

circleOP•8mo ago

That is also my question, why did I think like that. I think I misunderstood what they meant

circleOP•8mo ago

this works...

circleOP•8mo ago

just by commenting it I'm thinking of a PUT method for this that's why i abstracted the method, which I thought may be required

dan1st•8mo ago

you can also do void save(Project project); I think where the ID is in the project

circleOP•8mo ago

Yea, I saw a repo doing this implementation but I couldn't quite understand how it really works yet. I just read the docs on CrudRepository.save(), so even if it's an existing project, I may also want to use that instead?

dan1st•8mo ago

yes

circleOP•8mo ago

Ah, would this be the right implementation?

    @Override
    public void updateProject(Long id, Project project) {
        Project p = projectRepository.findById(id)
            .orElseThrow(() -> new ResourceNotFoundException("Project with id '" + id + "' could not be found!"));
        p.setName(project.getName());
        p.setDescription(project.getDescription());
        p.setImageUrl(project.getImageUrl());
        p.setTags(project.getTags());
        p.setProjectUrl(project.getProjectUrl());
        projectRepository.save(p);
    }

    @Override
    public void updateProject(Long id, Project project) {
        Project p = projectRepository.findById(id)
            .orElseThrow(() -> new ResourceNotFoundException("Project with id '" + id + "' could not be found!"));
        p.setName(project.getName());
        p.setDescription(project.getDescription());
        p.setImageUrl(project.getImageUrl());
        p.setTags(project.getTags());
        p.setProjectUrl(project.getProjectUrl());
        projectRepository.save(p);
    }

dan1st•8mo ago

yeah you should be able to do something like that and I think you might even do something like

project.setId(id);
projectRepository.save(project);

project.setId(id);
projectRepository.save(project);

though you'd need to test that (especially that this doesn't create a new project with a different ID)

circleOP•8mo ago

Hard to see what it does in the background, I can't find how it works underneath, only points out to the interface when i ctrl click it. I believe by doing that .setId then saving it, the .save method saves by looking up whether it exists or not? If it does exist, then it simply overwrite the previous value with the corresponding id?

dan1st•8mo ago

I think so but you'd need to test it it might be different if you use @GeneratedValue For testing it, you could - enable logging of the SQL statements and check what is executed in the DB - just add an existing one to the DB, change it with that approach and check which elements are in the DB afterwards
