1. Structure Layout by Features

 +- packagename
     +- projectname
         +- Application.java
         +- User
         |   +- User.java
         |   +- UserController.java
         |   +- UserService.java
         |   +- UserRepository.java
         +- order
             +- Order.java
             +- OrderController.java
             +- OrderService.java
             +- OrderRepository.java

2. Structure Layout by Layer

 +- packagename
     +- projectname
         +- Application.java
         +- models
         |   +- User.java
         |   +- Order.java
         +- controllers
         |   +- OrderController.java
         |   +- UserController.java
         +- services
         |    +- UserService.java
         |    +- OrderService.java
         +- repositories
         |    +- UserRepository.java
         |    +- OrderRepository.java   
         +- configs
         +- utils

In personally follow, Structure by Layout, which is best structure in my opinion. Some description regarding the folders

  1. models – as name, we can keep models/domain
  2. controllers – for keeping all controllers
  3. services – for all services
  4. repositories – keep all repositories
  5. configs – configurations like WebAppSercurity.java
  6. utils – feature specifics

Structure for Resource / Template / Static files in Spring Boot

Now we have created a structured folders for java code, it time for resource folders, where we keep our templates and static files. By default, you get templates and static folder in resources. In static you can create different assets folders and in template different sections like frontend and admin or backend. In templates, if you are using thymeleaf dependency, then you can keep fragments folder, where you keep parts of htmls.

β”œβ”€β”€ java (....)
└── resources
    β”œβ”€β”€ application.properties
    β”œβ”€β”€ static
    β”‚Β Β  └── assets
    β”‚Β Β      β”œβ”€β”€ admin
    β”‚Β Β      └── frontend
    └── templates
        β”œβ”€β”€ admin
        β”‚Β Β  β”œβ”€β”€ dashboard.html
        β”‚Β Β  └── fragments
        └── frontend
            β”œβ”€β”€ 403.html
            β”œβ”€β”€ about-us.html
            β”œβ”€β”€ fragments
