Vertx3入门应用
github地址：https://github.com/vert-x3
private void getConfig(Future
Vertx configVertx = Vertx.vertx();
configVertx.fileSystem().readFile(configDir + File.separator + "config.json",
res -> {
if (res.succeeded()) {
Buffer buf = res.result();
JsonObject config = buf.toJsonObject();
configVertx.close(re -> {
if (re.succeeded()) {
future.complete(config.getJsonObject("config"));
} else {
future.fail(re.cause());
}
});
} else {
future.fail(res.cause());
}
});
}
3、创建vertx集群环境
private void createVertx(Future
VertxOptions options = new VertxOptions();
options.setClustered(true);
ClusterManager mgr = new ZookeeperClusterManager();
options.setClusterHost("10.12.12.210");//本机zk地址
options.setClusterPort(clusterPort);
options.setClusterManager(mgr);
Vertx.clusteredVertx(options, res -> {
if (res.succeeded()) {
vertx = res.result();
future.complete();
} else {
future.fail(res.cause());
}
});
}
4、注册一个编解码器到eventbus：主要用于实体传输时的编解码
vertx.eventBus().registerDefaultCodec(Result.class, new ResultCodec());
5、部署verticle
private void deploy(String name, Handler
if (config != null) {
DeploymentOptions deploymentOptions =
new DeploymentOptions().setConfig(config).setInstances(1).setWorker(true);
vertx.deployVerticle(name, deploymentOptions, result -> {
if (result.succeeded()) {
String deployId = result.result();
handler.handle(Future.succeededFuture(deployId));
System.out.println(name + " 部署成功 ");
} else {
handler.handle(Future.failedFuture(result.cause()));
System.out.println(name + " 部署失败 " + result.cause().getMessage());
}
});
} else {
handler.handle(Future.failedFuture("Config is null"));
log.error(name + " 部署失败 ");
}
}
ManageVerticle
public class ManageVerticle extends AbstractVerticle {
protected Logger log = LoggerFactory.getLogger(this.getClass().getName());
private JsonObject config;

}
private Router configMainRouter() {
mainRouter.route().failureHandler(ErrorHandler.create(true));
/* Session / cookies for users */

mainRouter.route().handler(CookieHandler.create());

//二级子路由

future.complete(r.result());
} else {
future.fail("账号不存在");
}
} else {
future.fail("数据库错误：" + r.cause().getMessage());
}
});
}
}
MyRequestHandler
public class MyRequestHandler{
private Vertx vertx;
private JsonObject config;
public RobotRequestHandler(Vertx vertx, JsonObject config) {
this.vertx = vertx;
this.config = config;
}
public void dispatchRequest(RoutingContext rc) {
String userid = rc.request().getParam("userid");
JsonObject body = rc.getBodyAsJson();
JsonObject request = body.copy();
this.dao.getUser("user", userid, r -> {
if (r.succeeded() && r.result() != null) {
JsonObject user = r.result();
String username = user.getString("username");
HttpServerRequest request=rc.request();
HttpServerResponse response=rc.response();
try {
response.putHeader("Pragma", "no-cache");
response.putHeader("Cache-Control", "no-cache");
response.putHeader("Expires", "Thu, 01 Jan 1970 00:00:00 GMT");
response.putHeader("Content-Type", contenttype + ";charset=UTF-8");
response.end(user.toString());
} catch (Throwable e) {
rc.response().end(e.toString());
} finally {
}
} else {

}
});

1、获取进程PID
[java] view plain copy 在CODE上查看代码片派生到我的代码片
String name = ManagementFactory.getRuntimeMXBean().getName();
String pid = name.split("@")[0];
可以将它保存在文件中，用于动态停止进程
2、获取配置文件

Buffer buf = res.result();
JsonObject config = buf.toJsonObject();
configVertx.close(re -> {
if (re.succeeded()) {
future.complete(config.getJsonObject("config"));
} else {
future.fail(re.cause());
}
});
} else {
future.fail(res.cause());
}
