# vertxs
对Vert.x框架的封装
# Promise
## 1. 基本使用
```java
Vertx vertx = Vertx.vertx();
Promise.newInstance(vertx)
.then((context, onResult) -> {
context.put("result", "some text to share");
onResult.accept(true);
})
.then((context, onResult) -> onResult.accept(context.containsKey("result")))
.except((context) -> System.out.println("Failure: " + context.encode()))
.done((context) -> System.out.println("Success: " + context.encode()))
.timeout(3000)
.eval();
```
## 2. 多个回调并行
```java
Vertx vertx = Vertx.vertx();
Promise.newInstance(vertx)
.all((context, onResult) -> {
System.out.println("Also 'all' call 1");
onResult.accept(true);
},
(context, onResult) -> {
System.out.println("Also 'all' call 2");
onResult.accept(true);
})
.done((context) -> System.out.println("Success"))
.eval();
```
## 3. Promise Factory
```java
Vertx vertx = Vertx.vertx();
PromiseFactory factory = new PromiseFactory(vertx);
// Promise 1
factory.create().then((context, onResult) -> {
System.out.println("a new promise");
onResult.accept(true);
}).eval();
// Promise 2
factory.createParallel((context, onResult) -> {
System.out.println("a test");
onResult.accept(true);
},(context, onResult) -> {
System.out.println("a test 2");
onResult.accept(true);
}).eval();
```
# AOP
```java
Vertx vertx = Vertx.vertx();
HttpServer server = vertx.createHttpServer();
Router router = Router.router(vertx);
Route route = router.route(HttpMethod.POST, "/some/path");
ProxyHandler proxyHandler = new ProxyHandler(new Handler() {
@Override
public void handle(RoutingContext routingContext) {
HttpServerResponse response = routingContext.response();
response.setChunked(true);
response.putHeader("content-type", "text/plain");
response.write("this is a test route");
routingContext.response().end();
}
});
proxyHandler.withAop(new AopHandler() {
@Override
public void before(Object... args) {
System.out.println("aop before handler");
}
@Override
public void after(Object... args) {
System.out.println("aop after handler");
}
});
route.handler(proxyHandler);
server.requestHandler(router::accept).listen(8080);
```
