## 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
