Answer

Hi @maliming

Do you mean the project I currently working on? if yes, unfortunatly I can not But I could create sample project which repoduces this issue. I think it will be also easy for you

Steps

  1. Create module project
  2. Create entity with string Title property
  3. Add method SetTile which assigns Title on entity construction and fires local TitleCreated event
  4. Create TitleCreated event handler and make it throw excpetion
  5. Create application service with endpoint which creates Product in memory and saves it via repo. Create controller as well
  6. Create Application project
  7. Reference module in Application
  8. Run application and call endpoint
An exception occurred, but response has already started #953

Adding own abp module to monolith application #925
Answer

Hi @maliming

I have several modules which were inteded to wrok as microservices. These modules communicates with each other using Http API. But now I want put all modules in one application. My question is how to configure application that modules would get injected application services instead of http proxies, which provided by modules in application assembly?

@liangshiwei thanks for your reply. It is I looked for

Communication of modules in monolith #547
Answer

Sorry, but it does not look you answered on my questions. Maybe I understand that wrong. Can you please explain the way how to use 2 modules communicating with each other in monolith and use them again but as microservices (2 solutions using same modules: one as monolith, another one as microservices)? It is clear how modules communicate with each other in microservices - via API and events. But it is not clear how I can use same module (eg blogging module) in monolith. Should communication with built in module still be performed via API (monolith app accessing itself via network)?

Maybe you have some sample project for the monolith best practice? It will help a lot.
