9. Creating API to Upload Images in Spring Boot

[@vineethchinna3951]

Hi first of all thanks for the content 😃
have a small question at 7:50 why are we using @ManyToMany, my doubt is one product can have many images so it has be @OneToMany right? those images are only associated with this product right. If we are using @manyToMany those images can be associated to other products also right. I have this confusion can you please explain.

[@LearnProgrammingYourself]

Yes right @OneToMany is the best choice here. thanks for the suggestion

Many thanks for the explanation, I have a question, How can I test my RestAPI in a mock tool and upload the images ? (for example Postman) , the thing is that I haven't created the frontEnd like Angular or React yet. So I don't have a visual forms tool.

[@LearnProgrammingYourself]

need to check, I was getting issues while checking from postman. so I directly tested from angular UI

@@LearnProgrammingYourself Good day hope this finds you well. Please help testing this on post man. I n my case, I have a course with just cover image so i didn't make the separate table for that since its just one image instead added just a column. So when I test with post man using form-data it get error Required part 'course' is not present.]

Below is my code snippet

public Course SaveCourse(@RequestPart("course") Course course, @RequestPart("image")MultipartFile file) throws IOException {
//upload images

String contentType = file.getContentType();

[@haithammuhamad7892]

Excellent explanation ,
i want to ask you why you don't save image in file in the server not in database , becouse if alot of picture or file save in database it make it slowly .
thank you

[@LearnProgrammingYourself]

Yes in the future we can think on that. My current focus is on getting the things to work. But once we get the basic working application then we can think on enhancements
