vert.x 结合JAX-RS

Coding a simple REST Service with Vert-x

We will now run a bit more advanced example which will leverage a REST Service. This service, exposes a @GET Resource which will print out the parameter passed on the PATH URL of your Web application:

package
org.demo.vertx;

import
javax.ws.rs.GET;

import
javax.ws.rs.Path;

import
javax.ws.rs.PathParam;

import
javax.ws.rs.core.Response;

@Path
(
"/"
)

public
class
HelloWorldService {

@GET

@Path
(
"/{name:.*}"
)

public
 
Response doGet(
@PathParam
(
"name"
) String name) {

if
 
(name ==
null
 
|| name.isEmpty()) {

name =
"World"
;

}

return
 
Response.status(
200
).entity(
"Hello "
 
+ name).build();

}

}

Some changes will be required in your Verticle as well to build the JAX-RS controller deployment, adding to the JAX-RS registry the HelloWorldService:

package
 
org.demo.vertx;

import
 
io.vertx.core.AbstractVerticle;

import
 
org.jboss.resteasy.plugins.server.vertx.VertxRequestHandler;

import
 
org.jboss.resteasy.plugins.server.vertx.VertxResteasyDeployment;

public
 
class
 
DemoV
extends
 
AbstractVerticle {

@Override

public
 
void
 
start()
throws
 
Exception {

VertxResteasyDeployment deployment =
new
 
VertxResteasyDeployment();

deployment.start();

deployment.getRegistry().addPerInstanceResource(HelloWorldService.
class
);

// Start the front end server using the Jax-RS controller

vertx.createHttpServer()

.requestHandler(
new
 
VertxRequestHandler(vertx, deployment))

.listen(
8080
, ar -> {

System.out.println(
"Server started on port "
+ ar.result().actualPort());

});

}

}

In order to be able to build it, you need to include resteasy vert-x dependency:

<

<
groupId
>org.jboss.resteasy</
groupId
>

 
<
artifactId
>resteasy-vertx</
artifactId
>

 
<
version
>3.1.0.Final</
version
>

</
dependency

Let's test it!
