1:在src/conf目录下创建conf.json
{
"http.port" : 8082
}
2:创建Verticle,
config().getInteger("http.port", 8080),将会读取配置文件,是否有http.port,没有就使用8080作为默认,
package verticleTest;
import io.vertx.core.AbstractVerticle;
import io.vertx.core.Future;
public class ConfigVerticle extends AbstractVerticle{
public void start(Future<Void> fut) {
vertx
.createHttpServer()
.requestHandler(r -> {
r.response().end("<h1>Hello from my first " +
"Vert.x 3 application</h1>");
})
.listen(
// Retrieve the port from the configuration,
// default to 8080.
config().getInteger("http.port", 8080),
result -> {
if (result.succeeded()) {
fut.complete();
} else {
fut.fail(result.cause());
}
}
);
}
}
3:打包,发布。使用 -conf 将配置文件读入。
D:\Android\workspace1\Ali>java -jar target/Ali-0.0.1-SNAPSHOT-fat.jar -conf src/main/conf/conf.json
4:访问localhost:8082
