Create custom finder with spring

I trying to implement a database with a many-to-many relationship.The database has been built, now we need queries to it. I'm using this article as an example: https://www.bezkoder.com/jpa-many-to-many/. When I create custom finder in Repository - server crushes at running.
I have two Entity: MassageEntity and RstringsEntity. I'm trying to create a method List<MasageEntity> findMasageEntitiesByRstringsEntitiesId(Long string_id);. Without that method server starts.
This is what the error looks like.

I don't see the point in showing the controller, since the error occurs elsewhere.
What's I doing wrong? Maybe I need some settings or dependencies? Or I can solve the problem in a different way?

Your problem is the name of the query method: findMasageEntitiesByRstringsEntitiesId(Long. You need to use the field name from your entity class, not the class name.
I would try findMasageEntitiesByStringsId(Long.... (It's also a bit confusing that you've given the variable one name and the getter method another, not sure if JPA will like that.)
The other methods which returns a list also suffer from the same problem.

Could not create query for public abstract org.springframework.data.domain.Page com.example.repository.DocumentsRepository.findBytypeid

Hello all I have following 2 tables that are related:
CREATE TABLE `documents` (
`id` int(11) NOT NULL,
`date_created` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
`name` varchar(255) NOT NULL,
`type_id` int(11) NOT NULL,
`file` varchar(255) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
CREATE TABLE `documenttypes` (

The models are as following.

}
public void setFile(String file) {
this.file = file;
}
}
Here is the repositories:
document type repo:
package com.example.repository;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import com.example.model.Departments;
import com.example.model.Documenttypes;
#Repository
public interface DocumenttypesRepository extends CrudRepository<Documenttypes, Integer> {
}
And my documents repository
package com.example.repository;
import org.springframework.data.repository.CrudRepository;
import org.springframework.stereotype.Repository;
import java.util.Optional;
import org.springframework.boot.autoconfigure.data.web.SpringDataWebProperties.Pageable;
import org.springframework.data.domain.Page;
import org.springframework.data.jpa.repository.JpaRepository;
import com.example.model.Documents;
#Repository
public interface DocumentsRepository extends CrudRepository<Documents, Integer> {
Page<Documents> findBytypeid(Integer typeid, Pageable pageable);
Optional<Documents> findBytypeidAndDocumentId(Integer typeId, Integer id);
}
After all I am getting the following exceptions:

Please help. I don't even have a clue where I am actually scrooed up.

The thrown exception already explained what happens :
Caused by: java.lang.IllegalArgumentException: Paging query needs to have a Pageable parameter! Offending method public abstract org.springframework.data.domain.Page com.example.repository.DocumentsRepository.findBytypeid(java.lang.Integer,org.springframework.boot.autoconfigure.data.web.SpringDataWebProperties$Pageable)
And the Pageable should come from the spring-data package which its fully qualified name is org.springframework.data.domain.Pageable
So you are simply importing the wrong package for Pageable

getting ***BeanCreationException*** pls suggest a solution to solve this

My requirement is to insert the supplier along with catalogue and I only want to unidirectional mapping. Is there is anyway to resolve it with unidirectional only because I want to fetch catalogues from supplier(supplierId) and I am new to stackoverflow if there is any editing mistake please comment down, I will fix it.

I also want to know how to write search query for for item name in spring boot. Suppose, supplier A have Lays potato chips, banana chips, masala chips, coffee. I want to
search catalog items based on its supplierID and when I search for "chips" then it shows all types of chips supplier A have in catalog then how can I write such queries in CrudRepository/JpaRepository so that I can use it in service layer.

You should annotate with #ManyToOne and #JoinColumn.
#ManyToOne
#JoinColumn
private Supplier supplier;
Update (15/02/21)
As you added that you want an unidirectional relationship, this is the way, in the catalog class:
#Column
private int supplierId;
You can remove the supplier field or mark it as #Transient.
You must save the supplier, get its id (as it is generated by the database), and set it in your catalog.

Spring Data JPA OrderBy don't work [small letter][capital letter] type parameter

Hi~ I was in trouble using Spring Data JPA.
this trouble github url : https://github.com/moregorenine/toyproject/tree/jpa_self_join_save/tree-structure-ztree
Development environment
spring-boot-starter-parent : 2.0.6.RELEASE + JPA + H2
spring data jpa reference : https://docs.spring.io/spring-data/jpa/docs/current/reference/html/
Everything works fine. Except one.
don't work parameter type : [small letter][capital letter]... ex) tId
if change {tId} to {tempId} is good work!!! but I want use {tId}
ZTreeService.java
good work! no problem exmaple!!!
(O) zTrees = zTreeRepository.findAllByOrderById();
(O) zTrees = zTreeRepository.findAllByOrderByName();
(O) zTrees = zTreeRepository.findAllByOrderByIsParent();
don't work! only this type exmaple!!! why~
(X) zTrees = zTreeRepository.findAllByOrderByTId();
tId type parameter possible create, insert from spring data JPA.
But Does 'OrderBy' method not support [small letter][capital letter] type parameter?

Possibly caused by a bug in hibernate 5.2.14: hibernate.atlassian.net/browse/HHH-12332. Upgrading to 5.2.15 or to the latest version should fix it.

I had the same problem. I found out that there was a problem in my entity classes. I had used BigInteger for versioning.
#Version
private BigInteger version
I changed to Integer and problem was solved.

I had an #version annotation at a certain (same named) column in an automatically generated POJO class. After I had removed it, the error had gone.
e: similar to the solution of Ali, but for me it was not the datatype itself.
