i am working in jave, spring, mysql, hibernate environment

I have the following hql it gives me the correct out put

I have two entity classes as follows. The Parachute is the parent object and it has multiple Component objects. I need to have bidirectional @OneToMany implemented here.

Parent Parachute.java class.

I'm trying to make a complete copy of a Snowflake DB into PostgreSQL DB (every table/view, every row). I don't know the best way to go about accomplishing this. I've tried using a package called pipelinewise , but I could not get the access needed to convert a snowflake view to a postgreSQL table (it needs a unique id). Long story short it just would not work for me.

I've now moved on to using the snowflake-sqlalchemy package. So, I'm wondering what is the best way to just make a complete copy of the entire DB. Is it necessary to make a model for each table, because this is a big DB? I'm new to SQL alchemy in general, so I don't know exactly where to start. My guess is with reflections , but when I try the example below I'm not getting any results.

Im trying to make a generic instance mapper from an SQLite DB to my project logic layer. Each entry in the mapper is an instance of some class "DAL< name >" for example DALProduct all in the same package that extends class DALObject with the following structure:

We would like SwaggerUI, which is being generated by Swashbuckle, to show all controllers and methods when debugging as well as on our test environment, but hide some on integration and production environments. Note that the hidden controllers/methods will be functional in all scenarios but won't be documented in SwaggerUI.

To do this I've applied the principal described here.

Which results in following code:

Attribute definition:

** I am implementing role-based access control to my application. There are 3 users(Admin, Teacher, Student) in the application with same attribute so I created a basedUser entity to let them inherit it. I wished to get the user's authority when I select it from the database, so I created a type handler to convert the authority in String type to GrantedAuthority type in the process but I don't know why I keep getting this error: **

I have been looking for answers to this problem but not getting anywhere close, does anyone know how to solve this problem??

Entity

I using CleanArchitecture solution. I have Data layer where ApplicationDbContext and UnitOfWork are located :

I'm trying to move some C# code to F# and I'm struggling to achive that in a specific method. Lack of how to Seq and Pipeline work properly when using reflection.

Here's in C#

I'm getting this error because one of the fields in my domain class is a LocalDate. Stack trace below. Jackson is complaining about Java 8 date/time not being supported by default, but Spring Boot 2.5 comes with com.fasterxml.jackson.datatype:jackson-datatype-jsr310. How do I get Spring Batch to support my LocalDate field in my domain class?

If I change the field to be a java.util.Date it works perfectly.

Thanks!
