Java Implementation

运行方式

用./mvnw spring-boot:run运行 h2 database在 localhost:8080/h2-console

cURL测试

用cURL测试/api/v1/product/create curl -X POST -H "Content-Type: application/json" --data '{"name":"product1","price":"1.0","stock":"5"}' http://localhost:8080/api/v1/product/create 返回 {"code":201,"name":"product1","message":"Product created"}

再次用cURL测试/api/v1/product/create使用相同的name 返回 {"code":409,"message":"Product with the same name already exists"}

用cURL测试/api/v1/product/{id} curl -X GET -H "Content-Type: application/json" http://localhost:8080/api/v1/product/product1 返回 {"product":{"price":1.0,"name":"product1","stock":5},"code":200,"message":"Product retrieved"} 用cURL测试/api/v1/product/{id}使用不存在的name 返回 {"code":404,"message":"Product not found"}

代码结构

• controller: 接受请求parameters然后调用service
• service: 调用repository，处理业务逻辑。在必要时throw exception
• repository: 继承JpaRepository，和database交互存储数据
• product: Model class controller不直接调用repository,而是调用service负责业务逻辑。将来如要更改实现方式，只需更改service和repository，不用更改controller
