Servlet REST and Apache Tomcat example

This example shows how to use Servlet REST to define REST endpoints in Camel routes using the Rest DSL
This example is implemented in both the Java and XML DSLs. By default the Java DSL is in use. You can change this in the src/main/webapps/WEB-INF/web.xml file
For Java DSL the routes are defined in Java code, in the org.apache.camel.example.rest.UserRouteBuilder class. And for XML DSL the routes are define in XML code, in the src/main/resources/camel-config-xml.xml file.

There is a user REST service that supports the following operations

GET /user/{id} - to view a user with the given id
GET /user/final - to view all users
PUT /user - to update/create an user

The view operations are HTTP GET, and update is using HTTP PUT. From a web browser you can access the first two services using the following links

user/123 - to view the user with id 123
user/findAll - to list all users

From the command shell you can use curl to access the service as shown below:

    curl -X GET -H "Accept: application/json" http://localhost:8080/camel-example-servlet-rest-tomcat/rest/user/123
    curl -X GET -H "Accept: application/json" http://localhost:8080/camel-example-servlet-rest-tomcat/rest/user/findAll
    curl -X PUT -d "{ \"id\": 666, \"name\": \"The devil\"}" -H "Accept: application/json" http://localhost:8080/camel-example-servlet-rest-tomcat/rest/user

Notice when trying to get user with id 789 then there is a built-in delay of 0.5-2 seconds, to simulate some slowness in the service.

This example offers an API browser using Swagger which is accessible from the following link

api-docs/user - api of the user REST service
