book-store | Example of a book store management with MEAN STACK

I'm working on a spring-boot hibernate JPA personal project book-store. I'm facing a problem that the methods annotated with @Transactional annotation not rolling back transactions even with runtime exceptions. I'm using spring-boot version 1.5.1, hibernate version 5, java version 11 & DB is MySQL. I'm generating run time exception by inserting the book with the same title in books table. In BookServiceImpl's addBook method the store-entry should ideally rollback from the store table when adding the book to books table fails, but, it is currently not happening.

Below is bean config file code:

I try to write an angular app with IndexedDB for a little book-store. I set the index 'isbn' to unique and now I try to provoke the error because I want to tell the User that the isbn has to be unique and want to show the error message.

I can console.log(e) and get following output:

Event

This is my Zuul configuration (.yml file)

I have a project and i have to save all my data in text files.
One of those files is users.txt which contains all my users name
and password.

What i want to do is to read all my records from users.txt , and save them
in List of user, this process should be done when project starts.

The list could be increased or decreased depending on the processes of the project (Add User OR Delete User).

After that i want to save my list to the same file when the project is closed
(or when closing the program)

I hop it is clear to understand the idea of the project.

This my github repo which contain the project code.

User : is a class i have created and it has string username, string password and list of type user same as class name.

Im using the following dockerfile to build and run go application the application name is book-store and it's located under go/src/book-store in my local mac.

I’ve created a docker image and pushed it to docker hub as public repo. When I try to do pull it, I get an error:

I have a page slugged book-store. I want this page to have different sections, namely: category and book. I'd like to use rewrite rules to achieve pretty urls that match the following example routes:

In my vue app, I have an array of objects which I want to render as a list. Within each object, there is a 'parent' property which contains info about who the parent is thereby giving us a hierarchical data structure. However, I am unable to show this hierarichal list. I tried creatin a tree by transforming the data but my code seems bugged.

I'm setting up a newsletter for a client, but it continuously blows up images and won't read container widths. I've tried adding strict widths on every single layer and turing all divs into tables. Does anyone know why Outlook 2013 might not recognize CSS styles for containers? This only seems to happen in Outlook 2013 and I so far haven't been able to find a means of fixing this yet.
