2, SpringCloud basic use of the gateway component zuul
Introduction: explain the basic use zuul gateway
1, adding dependence
2, start class add comments @EnableZuulProxy
default integrated circuit breaker @EnableCircuitBreaker
default access rules
http: // gateway: port / service -id / * *
example:? default / the Order-Service / API / v1 / the Order / the Save user_id = 2 & product_id = 1
? custom / xdclass_order / api / v1 / order / save user_id = 2 & product_id = 1
custom routing forwarding:
Zuul:
routes:
the Order -service: / apigateway / **
environmental isolation configuration:
demand: do not want to expose the external interface to the default service
/ order-service / api / v1 / order / save
configurations:
Zuul:
ignored-patterns:
- /*-service/api/v1/order/save
Start
New Project reply before some data before the analog, for example, 2 seconds delay ProductService which here commented.
New Project
You need to sign up to the registry.
Select Gateway Zuul
chose these two
default dependency when creating the project has come in loaded
configuration file format changed yml
need a name to the application from. spring.a will only prompt, select application.name first one will be able to
specify the address registry
start classes annotated
notes of EnableZuulProxy
Start the application
api-gateway is registered to the registry
default access rules
http: // gateway: port / service -id / **
Example:? default / order-service / api / v1 / order / save user_id = 2 & product_id = 1
Custom / xdclass_order / api / v1 / order / save ? user_id = 2 & product_id = 1
this is the address of the service access to the original order
through the gateway access interface service orders. Now is the gateway through Zuul
had direct access productService of
access through the gateway productService
Custom Path Rules
apigateway replaces the order-service
restart the application to test
the default is accessed using the order-service of
replaced apigateway
ignored product-service. Goods and services not provided to the external routing
restart the service
order service is normally accessible
product-service may be original access, access is now less than
ignored: / * - service / **
a * match everything between the two slashes, ** is everything after the match slashes.
Restart the application
to goods and services also add to the mix
of goods and services can also access a list of data interfaces to
directly access the product through the port services is not possible through the gateway. Port 8773
Environmental isolation
Environmental isolation configuration:
Demand: do not want to expose the external interface to the default service
/ order-service / api / v1 / order / save
actually deployed inside and outside the network isolation is the way
