Start your spring boot application like this:

This happens when in your source code doesn't have any API listened, it means there aren't any classes marked with @RestController or @Controller anonation in your source code, SpringBoot at this time just simply build source code run and exit without returning any error messages

I am not sure what Deserializer are you using, but with the Jackson ObjectMapper I solved it changing the method names of the getter and setter for the developers properties: they should be called setDevelopers and getDevelopers. In your code they are called setDeveloper and getDeveloper, without the final S.

To avoid problem like these, I just add Lombok as a dependency and it takes care of creating setters and getters.

With Lombok your Team class would look like this:

Change hibernate configuration

Error message is explicit , this is not correct

I cannot run your code because you only provide a few little snippets, but what I noticed is:

• As for the difference between @target() and @within() in Spring AOP and also in AspectJ, see my answer here.
• Your annotation has @Target({ElementType.TYPE, ElementType.METHOD}), but both your pointcuts only target annotated types, not annotated methods. For that you would need to use @annotation. I.e. your annotated method will never be matched by this pointcut and consequently the advice will never fire.
• Your exception must come from another pointcut/advice pair, not the ones you have shown in your question - probably something global like execution(* *(..)) or within(*) or target(*) which will try to weave into all kinds of Spring components, both your own and internal ones. So you need to limit that other pointcut to something like execution(* my.base.package..*(..)) or within(my.base.package..*) or target(my.base.package..*) or at least exclude internal Spring packages you don't wish to intercept via !within(org.springframework..*).

Edit

Ensure that you update the tags before you save note. Also make sure that the service method saveNote in NoteServiceImpl is also annotated with @Transactional so that rollback will be initiated in case the query gets interrupted for some reason. I was able to reproduce the issue that you faced and guardian is right about how Hibernate handles such situations. You cannot save data to multiple tables in a single SQL command (this is related to Atomicity) but you achieve that using transactions. Here is a fantastic answer related to this.

In your code, you need to change saveNote method in NoteDaoImpl if you still want to save tags while saving data into T_NOTE.
