端点 returns 大概是云配置

Question

我有这个简单的控制器

@RestController
@RequestMapping("/metrics")
public class MetricsController {

    @GetMapping
    @ApiOperation("Get metrics by source")
    public ResponseEntity<List<Metric>> getMetricBySource(@RequestParam String source) {
        if (source.equalsIgnoreCase("recordings")) {
            return new ResponseEntity<>(MetricsConstants.RECORDINGS_METRICS, HttpStatus.OK);
        } else if (source.equalsIgnoreCase("advertisers")) {
            return new ResponseEntity<>(MetricsConstants.ADVERTISERS_METRICS, HttpStatus.OK);
        } else if (source.equalsIgnoreCase("publishers")) {
            return new ResponseEntity<>(MetricsConstants.PUBLISHERS_METRICS, HttpStatus.OK);
        } else if (source.equalsIgnoreCase("partners")) {
            return new ResponseEntity<>(MetricsConstants.PARTNERS_METRICS, HttpStatus.OK);
        } else if (source.equalsIgnoreCase("products")) {
            return new ResponseEntity<>(MetricsConstants.PRODUCTS_METRICS, HttpStatus.OK);
        } else if (source.equalsIgnoreCase("regular-users")) {
            return new ResponseEntity<>(MetricsConstants.REGULAR_USERS_METRICS, HttpStatus.OK);
        }

        return null;
    }

}

现在，当我尝试通过
访问端点时 localhost:8099/metrics?source=advertisers

代码流甚至没有转到方法（尝试使用调试器）。只有这个新创建的端点存在问题。最后一个错误是

Full authentication is required to access this resource

直到我写了一段配置：

management:
  security:
    enabled: false

我用

springBootVersion = '1.5.3.RELEASE'
springCloudVersion = 'Dalston.RELEASE'

Answer 1

问题出在 Spring Cloud MetricsInterceptorConfiguration。

据我了解，您可以在每个端点上添加后缀路径 /metrics 以查看 Spring Cloud 提供的此端点的指标。所以它只是拦截了我的映射:)

我通过向 bootstrap.yml 添加以下配置解决了这个问题：

endpoints:
  metrics:
    enabled: false

端点 returns 大概是云配置

Endpoint returns presumably cloud config

spring-mvc

spring-cloud
