测试接口

  • 新增接口

http://localhost:8001/payment/save?serial=ray123

  • 查询接口

http://localhost:8001/payment/get/130

到此，8001端口通过自测。

复制

import org.springframework.boot.SpringApplication;

public class OrderMain80 {

    public static void main(String[] args) {
        SpringApplication.run(OrderMain80.class, args);
    }
}

测试接口

  • 确保两个端口同时启动
  • 新增接口

http://localhost/consumer/payment/save?serial=ray234

问题：提示插入成功，但是却没有内容

解决：修改 8001 端口的 save 方法

代码语言：javascript
复制
@PostMapping(value = "/save")
public CommonResult save(@RequestBody Payment payment) {
    int result = paymentService.save(payment);
    log.info("新增结果: [{}]", result);

    if (result > 0) {
        return new CommonResult(200, "新增数据成功，ID: " + payment.getId(), result);
    }
    return new CommonResult(500, "新增数据失败", null);
}

在参数前面新增 @RequestBody 注解

  • 查询接口

http://localhost/consumer/payment/get/136
