cloud-provider-payment8001微服务提供者支付Module模块

代码我上传到了github 😦 (点击他)
项目结构:

建表SQL

CREATE TABLE `payment` (`id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'ID',`serial` varchar(200) DEFAULT '',PRIMARY KEY (`id`)) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8

注意:在github 上面的我电脑装了8.0和5.7 我的端口号 自己改了一下

测试

运行主类:
网页访问:

http://localhost:8001/payment/get/31

post请求需要用postman

http://localhost:8001/payment/create?serial=xio

注意()


如果是以下情况:

public CommonResult create(@RequestBody Payment payment)  // 加了 @RequestBody postman 就要 传raw的 json

http://localhost:8001/payment/create

{"serial": "wwu002"
}

出现这个就成功了
