Zuul + Ribbon 重试 - maxAutoRetries 不起作用，只重试一次
Zuul + Ribbon Retry - maxAutoRetries not working, only retries once
我已经对此进行了一段时间的修改，但我不明白为什么我的功能区重试只重试了一次。我在 localhost:9080 有一个节点服务器服务器 运行，我看到请求进来了。我将它设置为 return 200 每 3 个请求中有一个，否则 500 (200, 500, 500、200、500、500……）。这是我的 application.yaml:
zuul:
hosts:
connect-timeout-millis: 1000
socket-timeout-millis: 2000
routes:
foo:
path: /foo/*
serviceId: foo
bar:
path: /foo/*/bar/
serviceId: bar
retryable: true
add-host-header: true
add-proxy-headers: true
# ribbon-isolation-strategy: thread
ribbon:
eureka:
enabled: false
eager-load:
enabled: true
bar:
ribbon:
maxAutoRetries: 5
maxAutoRetriesNextServer: 0
retryableStatusCodes: 500
listOfServers: http://localhost:9080
foo:
ribbon:
maxAutoRetries: 5
maxAutoRetriesNextServer: 0
retryableStatusCodes: 500
listOfServers: http://localhost:9080
management:
security:
enabled: false
hystrix:
command:
default:
execution:
isolation:
# strategy: THREAD
thread:
timeoutInMilliseconds: 100000
我已验证 retryable: true 正在运行，我没有将其设置为 false 进行任何重试。 listOfServers 也很有效，因为我看到请求进入本地主机。 retryableStatusCodes 似乎也在工作，因为我重试了一次 500。这是我在节点服务器出现两个 500 错误后得到的堆栈跟踪：

使用 Edgware.SR3，spring-cloud-starter-zuul (@EnableZuulProxy) 和 org.springframework.retry:spring-retry:1.1.5.RELEASE 在类路径。
有什么想法吗？
MaxAutoRetries。它区分大小写，并且与我正在使用的其他属性的大小写样式不匹配。这么多小时...
我已经对此进行了一段时间的修改，但我不明白为什么我的功能区重试只重试了一次。我在 localhost:9080 有一个节点服务器服务器 运行，我看到请求进来了。我将它设置为 return 200 每 3 个请求中有一个，否则 500 (200, 500, 500、200、500、500……）。这是我的 application.yaml:
zuul:
hosts:
connect-timeout-millis: 1000
socket-timeout-millis: 2000
routes:
foo:
path: /foo/*
serviceId: foo
bar:
path: /foo/*/bar/
serviceId: bar
retryable: true
add-host-header: true
add-proxy-headers: true
# ribbon-isolation-strategy: thread
ribbon:
eureka:

eager-load:
enabled: true
bar:
ribbon:
maxAutoRetries: 5
maxAutoRetriesNextServer: 0
retryableStatusCodes: 500
listOfServers: http://localhost:9080
foo:
ribbon:
maxAutoRetries: 5
maxAutoRetriesNextServer: 0
retryableStatusCodes: 500
listOfServers: http://localhost:9080
management:
security:
enabled: false
hystrix:
command:
default:
execution:
isolation:
# strategy: THREAD
thread:
timeoutInMilliseconds: 100000
我已验证 retryable: true 正在运行，我没有将其设置为 false 进行任何重试。 listOfServers 也很有效，因为我看到请求进入本地主机。 retryableStatusCodes 似乎也在工作，因为我重试了一次 500。这是我在节点服务器出现两个 500 错误后得到的堆栈跟踪：
