客户端使用RestTemplate.getPostObject（）到服务器，但是@RequestBody无法解析

问题描述 投票：0回答：1

Springboot 2.2.2 + SpringCloud Hoxton SR1

这只是一个订单付款演示。

这是我的代码，用于客户端创建服务器订单：

@Resource
private RestTemplate restTemplate;

@GetMapping(value = "/consumer/payment/create")
public CommonResult<Payment> create(Payment payment){
    return restTemplate.postForObject(PAYMENT_URL + "/payment/create", payment, CommonResult.class);
}

服务器代码

@PostMapping(value = "/payment/create")
public CommonResult create(@RequestBody Payment payment){
    int result = paymentService.create(payment);
    log.info("******result：" + result + "******" + payment + "******");
    if(result > 0){
        return new CommonResult(200, "insert success，ServerPort：" + serverPort, result);
    }else {
        return new CommonResult(444, "insert failed，ServerPort：" + serverPort, null);
    }
}

然后

我用邮递员发送地址：

http://localhost/consumer/payment/create?serial=tom

客户端错误是：

服务器警告为：

Resolved [org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/xml;charset=UTF-8' not supported]

我在服务器端调试了create方法。使用邮递员发送get请求后，我发现未执行create方法，或者未进入函数体，但是在调试客户端时，我发现他已经返回了结果。

当我删除@RequestBody时可以使用，但“付款”的内容为null。

在我看来，@RequestBody拒绝了我的请求并返回了错误消息。

这是我的application.yml

server:
  port: 80

spring:
  application:
    name: cloud-order-service

 eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:7001/eureka/, http://localhost:7002/eureka/

和ApplicatonConfig

@Configuration
public class ApplicationContextConfig {

    @Bean
    @LoadBalanced
    public RestTemplate getRestTemplete(){
        return new RestTemplate();
    }
}

我不知道发生了什么事，请帮我...

@GetMapping(value = "/consumer/payment/create")
    public CommonResult<Payment> create(Payment payment){
        JSONObject jsonObject = new JSONObject();
        jsonObject.put("id", payment.getId());
        jsonObject.put("serial", payment.getSerial());
        HttpHeaders headers = new HttpHeaders();
        headers.add("Content-Type", "application/json");
        HttpEntity<Object> entity = new HttpEntity<>(jsonObject, headers);
        return restTemplate.postForObject(PAYMENT_URL + "/payment/create", entity, CommonResult.class);
    }
