java spring spring-boot maven spring-data-jdbc

Why does HSQLDB and Spring Data JDBC claim my table does not exist?

I posted something similar of the same issue a few days ago but now I think I (with the help of some of the people who commented on the post) narrowed it down to know what I need help with exactly. I am trying to use the Spring Data JDBC in my application with the HSQLDB (am not trying to use a web server). But the driver doesn't support the get/set timeout for connections. Because of that, I cannot even use the database.

Here is the pom.xml:

Here is the schema.sql file:

CREATE TABLE Students (
    id INTEGER IDENTITY PRIMARY KEY,
    fName VARCHAR(50),
    lName VARCHAR(50),
    rank VARCHAR(50)
);

Here is the application.properties file:

logging.level.sql=debug
spring.datasource.generate-unique-name=false

Here is the main class:

package com.example.demo;

import org.springframework.boot.ApplicationRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Bean
    ApplicationRunner applicationRunner(StudentRepo studentRepo) {
        return args -> {
            var s1 = Student.createStudent("John", "Doe");
            s1.setId(1l);
            var s2 = Student.createStudent("Jane", "Doe");
            s2.setId(2l);
            System.out.println(studentRepo.save(s1));
            System.out.println(studentRepo.save(s2));
            System.out.println(studentRepo.findByFName("John"));
        };
    }
}

Here is the StudentRepo interface:

package com.example.demo;

import org.springframework.data.jdbc.repository.query.Query;
import org.springframework.data.repository.CrudRepository;
import org.springframework.data.repository.query.Param;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface StudentRepo extends CrudRepository<Student, Long> {

    @Query("SELECT * FROM Students WHERE fName = :name")
    List<Student> findByFName(@Param("name") String fName);
}

And here is the INFO log statement:

Solution

So after a few tries to reproduce and make it work, i could get it done with the following changes:

In schema.sql:

CREATE TABLE "Student"
(
    "id"    INTEGER GENERATED BY DEFAULT AS IDENTITY PRIMARY KEY,
    "fName" VARCHAR(50),
    "lName" VARCHAR(50),
    "rank"  VARCHAR(50)
);

The first change is to remove the s at the end of Student, the second change is to make the id column autogenerated. I also added double quotes to all names, so that HSQLDB is using case isensitivity here.

In the Student class:

@Data
@Table("Student")
public class Student {

    @Id
    @Column("id")
    private long id;

    @Column("fName")
    private String fName;

    @Column("lName")
    private String lName;

    @Column("rank")
    private String rank;
}

Basically i specified the column and table names, otherwise Spring Data will use the default naming strategy, which will e.g. convert camel case field names using underscore (e.g. for the field name fName the mapped column name would be F_NAME).
I also added the Id annotation to the Id field, so that Spring Data can properly handle the checks if it's a new entity or not (based on that Spring Data will either use Insert or Update statements). Without that annotation, you would have to implement another interface to provide that functionality (i found an explanation here: https://prog.world/how-spring-data-jdbc-determines-when-an-object-is-new/)

In the StudentRepo:

public interface StudentRepo extends CrudRepository<Student, Long> {

    @Query("SELECT * FROM \"Student\" WHERE \"fName\" = :name")
    List<Student> findByFName(@Param("name") String fName);
}

I also removed the suffix s from the table name here and added the double quotes
