如何在春季创建多Web模块应用程序？

Question

I'm trying to create a multi-web module application in spring. Below is the project structure.

+-- Parent
|---- Java (Which has the controller, models and views)
|---- resources
|---- webapp
|------ web.xml
|------ jsp 
+-- Purchase (Submodule 1)
|---- Java (Which has the controller, models and views)
|---- resources
|---- webapp
|------ web.xml
|------ jsp 
+-- Sales (Submodule 2)
|---- Java (Which has the controller, models and views)
|---- resources
|---- webapp
|------ web.xml
|------ jsp 

I want to build purchase (submodule 1) and sales (submodule2) as separate jar or war and add it to the lib of parent and run the application and access the controllers as

localhost:8080/parent
localhost:8080/purchase
localhost:8080/sales

Could someone let me know the approach that available in spring to achieve the thing it would be helpful

Thanks in advance!

Answer 1

Regarding the structure and responsibility for each project, I would suggest modeling it like

parent

• web-service (only controllers and views, no business logic, delegates to sales and purchase for business logic)
• sales (sales business logic - no controllers and views)
• purchase (purchase business logic - no controllers and views)

You might have to add additional modules for utils / persistence / entities , depending on your specific requirements.

Regarding building per se, there are a couple of options here, the most widely used bing maven and gradle . Both of them support structuring an application in parent - child modules. Both of them support adding dependencies for a child module in another child module (so you are able to add dependencies on sales and purchase in web-service ).

Both maven and gradle will take care to build all needed dependencies for a given module before building that module (so it is guaranteed that sales and purchase will be built before web-service ). Both maven and gradle will fail the build if they are not able to satisfy a dependency.

I think it is about the which web server you use. Just set them different context roots. You should take a look at this answer https://stackoverflow.com/a/32008624/7541163
