== Spring Boot Example with Camel exposing REST services using Apache CXF
|
||||
|
||||
=== Introduction
|
||||
|
||||
This example illustrates how to use https://projects.spring.io/spring-boot/[Spring Boot] with http://camel.apache.org[Camel]. It provides a simple REST service that is created using https://cxf.apache.org/[Apache CXF].
|
||||
|
||||
|
||||
=== Build
|
||||
|
||||
You can build this example using:
|
||||
|
||||
$ mvn package
|
||||
|
||||
=== Run
|
||||
|
||||
You can run this example using:
|
||||
|
||||
$ mvn spring-boot:run
|
||||
|
||||
After the Spring Boot application is started, you can open the following URL in your web browser to access the list of services: http://localhost:8080/services/ including WADL definition
|
||||
|
||||
You can also access the REST endpoint from the command line:
|
||||
|
||||
List all the users
|
||||
[source,text]
|
||||
----
|
||||
$ curl http://localhost:8080/services/api/user -s | jq .
|
||||
----
|
||||
|
||||
The command will produce the following output:
|
||||
|
||||
[source,json]
|
||||
----
|
||||
[ {
|
||||
"id" : 1,
|
||||
"name" : "John Coltrane"
|
||||
}, {
|
||||
"id" : 2,
|
||||
"name" : "Miles Davis"
|
||||
}, {
|
||||
"id" : 3,
|
||||
"name" : "Sonny Rollins"
|
||||
} ]
|
||||
----
|
||||
|
||||
Retrieve a specific user
|
||||
[source,text]
|
||||
----
|
||||
$ curl http://localhost:8080/services/api/user/1 -s | jq .
|
||||
----
|
||||
|
||||
The command will produce the following output:
|
||||
|
||||
[source,json]
|
||||
----
|
||||
{
|
||||
"id": 1,
|
||||
"name": "John Coltrane"
|
||||
}
|
||||
----
|
||||
|
||||
Insert/update user
|
||||
|
||||
[source,text]
|
||||
----
|
||||
$ curl -X PUT http://localhost:8080/services/api/user --data '{"id":4,"name":"Charlie Parker"}' -H 'Content-Type: application/json' -v
|
||||
----
|
||||
|
||||
The http status code of the response will be https://www.iana.org/assignments/http-status-codes/http-status-codes.xhtml#http-status-codes-1[201]
|
||||
|
||||
Moreover, the input user is validated according to the annotations on the link:src/main/java/org/apache/camel/example/springboot/cxf/User.java[User bean]
|
||||
|
||||
[source,text]
|
||||
----
|
||||
$ curl -X PUT http://localhost:8080/services/api/user --data '{"id":4,"name":"C"}' -H 'Content-Type: application/json'
|
||||
----
|
||||
|
||||
will produce a validation error
|
||||
|
||||
|
||||
The Spring Boot application can be stopped pressing `[CTRL] + [C]` in the shell.
|
||||
