# About Spring Cloud and Java Chassis interoperability
2+
3+
In this demo, we build a gateway using spring-cloud-gateway, a microservice `provider-java-chassis` using Java Chassis, a microservice `provider-spring-cloud` using Spring Cloud.
4+
5+
Scenario 1: User -> gateway -> provider-spring-cloud -> provider-java-chassis
6+
7+
Request:
8+
9+
`http://localhost:9090/spring-cloud/sayHello?name=World`
10+
11+
Result:
12+
13+
`"Hello from Java Chassis, World"`
14+
15+
16+
Scenario 2: User -> gateway -> provider-java-chassis -> provider-spring-cloud
17+
18+
Request:
19+
20+
`http://localhost:9090/java-chassis/sayHello?name=World`
21+
22+
Result:
23+
24+
`"Hello from Spring Cloud, World"`
25+
26+
## Using Service Center & Kie
27+
28+
Maven profile and Spring Profile using `servicecomb`.
29+
30+
## Using Nacos
31+
32+
Maven profile and Spring Profile using `nacos`.
33+
34+
>>> Notice: Nacos 2.3.0 and above is required. Because older versions of nacos will not generate instance id for Spring Cloud applications and Java Chassis interoperability needs instance id.
