Zuul代理无法路由，导致com.netflix.Zuul.exception.ZUULException：转发错误

Question

我有简单的服务如下：

TRANSACTIONS-API-SERVICE    n/a (1) (1) UP (1) - 192.168.2.12:transactions-api-service:8083
TRANSACTIONS-CORE-SERVICE   n/a (1) (1) UP (1) - 192.168.2.12:transactions-core-service:8087

@SpringBootApplication

@Controller

@EnableZuulProxy

public class ZuulApplication {

    public static void main(String[] args) {
        new SpringApplicationBuilder(ZuulApplication.class).web(true).run(args);
    }
}

Zuul配置：

===============================================

info:
  component: Zuul Server

server:
  port: 8765

endpoints:
  restart:
    enabled: true
  shutdown:
    enabled: true
  health:
    sensitive: false

zuul:
  ignoredServices: "*"
  routes:
    transactions-api-service: 
    path: transactions/accounts/**
    serviceId: transactions-api-service

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

logging:
  level:
    ROOT: INFO
    org.springframework.web: DEBUG

===============================================

当我尝试用url(http://localhost:8765/transactions/accounts/123/transactions/786)调用transactions-api-service时，我得到了Zuul异常：

2016-02-13 11:29:29.050 WARN 4936---[nio-8765-exec-1]O.S.C.N.Z.Filters.Post.SenderRorFilter：筛选过程中出错

我在Zuul上缺少任何配置吗？

您需要通过在zuul服务器的application.yml中添加此属性来更改zuul执行超时：

# Increase the Hystrix timeout to 60s (globally)
hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 60000
