This example demonstrates how to develop RESTful web service with CDI managed beans and a Servlet 3.0 Web container.
The mapping of the URI path space is presented in the following table:
| URI path | Description | Expected Results |
|---|---|---|
| /cdi-webapp/helloworld | A managed bean with no use of injection whatsoever | Hello World |
| /cdi-webapp/singleton | Shows injection of context objects into the fields of a managed bean. | OK GET /cdi-webapp/singleton |
| /cdi-webapp/singleton/counter | Shows injection of context objects into the fields of a managed bean. | standalone Grizzly (no resource injection support) - 0 initial increment value, that gets incremented with each other request |
| Java EE compliant AS - 42 initial increment value | ||
| /cdi-webapp/other/C/D | Shows injection of context objects and path parameters into the fields of a managed bean. | INTERCEPTED: OK GET /cdi-webapp/other, c=C, d=D |
| /cdi-webapp/echofield/b?a=a | Shows injection of path and query parameters into the fields of a managed bean. | ECHO a b |
| /cdi-webapp/echo/a | A managed bean that uses (but does not inject) a path parameter. | ECHO a |
This example should work on any Java EE 7 compliant application server. It has been tested on a standalone GlassFish 4 instance. The easiest way to get the application running there is to build it and deploy as follows:
mvn clean package
$AS_HOME/asadmin deploy target/cdi-webapp.war
Another option, introduced in Jersey 2.15, is to run this example in Grizzly HTTP server. To get the application running there you just invoke the following command:
mvn clean compile exec:java
Since Weld Servlet support is provided also for Apache Tomcat server,
there is yet another way how to deploy the application. Use the
tomcat-packaging maven profile to get the WAR archive packaged in a
way that makes it ready for Tomcat 7+ deployment:
mvn -Ptomcat-packaging clean package
cp target/cdi-webapp.war $CATALINA_HOME/webapps
After you successfully deploy the application, visit the following URLs:
