解决SpringCloud Feign传对象参数调用失败的问题
作者：itdragons
这篇文章主要介绍了解决SpringCloud Feign传对象参数调用失败的问题，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教
SpringCloud Feign传对象参数调用失败
- 不支持GET请求方式
- 使用Apache HttpClient替换Feign原生httpclient
- @RequestBody接收json参数
bootstrap-local.yml
feign:
httpclient:
enabled: true
pom.xml
<!-- 使用Apache HttpClient替换Feign原生httpclient -->
<dependency>
<groupId>com.netflix.feign</groupId>
<artifactId>feign-httpclient</artifactId>
<version>8.18.0</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.5.3</version>
</dependency>
feignClient：
@FeignClient(name = "hd-ucenter-server", fallback = SysTestServerFallbackImpl.class)
public interface SysTestServer {
@RequestMapping(value = "/test/test", method = RequestMethod.POST, consumes = "application/json")
Object test(CurrentUser currentUser);
}
RestController：
@RestController
@PostMapping("/test")
public class TestController {
@RequestMapping(value = "/test")
public Object test(@RequestBody CurrentUser currentUser) {
System.out.printf("调用test\n");
return currentUser;
}
}
SpringCloud中Feign异常无法传递的问题
因为 cloud内部抛出异常不进行处理，Feign获取spring默认包装异常结果如下：
{
"timestamp": "2017-12-27 15:01:53",
"status": 500,
"error": "Internal Server Error",
"exception": "com.keruyun.loyalty.commons.master.exception.BusinessException",
"message": "Request processing failed; nested exception is {\"code\":1000, \"message\":\"test Exception\"}",
"path": "/coupon/cloud/commercial/8469"
}
自定义的异常处理下返回状态
@Slf4j
@RestControllerAdvice
public class GlobalExceptionHandlerResolver {
//内部服务异常处理
@ExceptionHandler(InternalApiException.class)
public ResultResp<?> handleGlobalException(HttpServletResponse response, InternalApiException internalApiException) {
ResultResp<?> resultResp = internalApiException.getResultResp();
log.error(internalApiException.getMessage(), internalApiException);
response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());//返回500异常
response.setContentType(MediaType.APPLICATION_JSON_UTF8.toString());
return resultResp;
}
}
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
