Introduction

Fast, lightweight Web framework based on Netty; without too much dependency, and the core jar package is only 30KB.

If you are interested, please click Star.

Features

  • Clean code, without too much dependency.
  • One line of code to start the HTTP service.
  • Custom interceptor.
  • Flexible parameters way.
  • Response json.
  • Start with jar.
  • Custom configuration.
  • Multiple response ways.
  • Pluggable IOC beanFactory。
  • Support Cookie.
  • File Upload.

Quick Start

Create a project with Maven, import core dependency.

<dependency>
    <groupId>top.crossoverjie.opensource</groupId>
    <artifactId>cicada-core</artifactId>
    <version>x.y.z</version>
</dependency>

start class:

public class MainStart {

    public static void main(String[] args) throws InterruptedException {
        CicadaServer.start(MainStart.class,"/cicada-example") ;
    }
}

Configuring Business Action

@CicadaAction("routeAction")
public class RouteAction {

    private static final Logger LOGGER = LoggerBuilder.getLogger(RouteAction.class);


    @CicadaRoute("getUser")
    public void getUser(DemoReq req){

        LOGGER.info(req.toString());
        WorkRes<DemoReq> reqWorkRes = new WorkRes<>() ;
        reqWorkRes.setMessage("hello =" + req.getName());
        CicadaContext.getContext().json(reqWorkRes) ;
    }

    @CicadaRoute("getInfo")
    public void getInfo(DemoReq req){

        WorkRes<DemoReq> reqWorkRes = new WorkRes<>() ;
        reqWorkRes.setMessage("getInfo =" + req.toString());
        CicadaContext.getContext().json(reqWorkRes) ;
    }

    @CicadaRoute("getReq")
    public void getReq(CicadaContext context,DemoReq req){

        WorkRes<DemoReq> reqWorkRes = new WorkRes<>() ;
        reqWorkRes.setMessage("getReq =" + req.toString());
        context.json(reqWorkRes) ;
    }



}

Launch and apply access: http://127.0.0.1:5688/cicada-example/routeAction/getUser?id=1234&name=zhangsan

{"message":"hello =zhangsan"}

Cicada Context

Through context.json(), context.text(), you can choose different response ways.

@CicadaAction("routeAction")
public class RouteAction {

    private static final Logger LOGGER = LoggerBuilder.getLogger(RouteAction.class);

    @CicadaRoute("getUser")
    public void getUser(DemoReq req){

        LOGGER.info(req.toString());
        WorkRes<DemoReq> reqWorkRes = new WorkRes<>() ;
        reqWorkRes.setMessage("hello =" + req.getName());
        CicadaContext.getContext().json(reqWorkRes) ;
    }
    
    @CicadaRoute("hello")
    public void hello() throws Exception {
        CicadaContext context = CicadaContext.getContext();

        String url = context.request().getUrl();
        String method = context.request().getMethod();
        context.text("hello world url=" + url + " method=" + method);
    }    


}

Cookie Support

Set Cookie

Cookie cookie = new Cookie() ;
cookie.setName("cookie");
cookie.setValue("value");
CicadaContext.getResponse().setCookie(cookie);

Get Cookie

Cookie cookie = CicadaContext.getRequest().getCookie("cookie");
logger.info("cookie = " + cookie.toString());

Custom configuration

By default, the configuration file under the classpath is read.

You can also customize the configuration file.

Just need to extends top.crossoverjie.cicada.server.configuration.AbstractCicadaConfiguration class.

Write the name of the configuration file at the same time.

Like this:

public class RedisConfiguration extends AbstractCicadaConfiguration {


    public RedisConfiguration() {
        super.setPropertiesName("redis.properties");
    }

}

public class KafkaConfiguration extends AbstractCicadaConfiguration {

    public KafkaConfiguration() {
        super.setPropertiesName("kafka.properties");
    }


}

Get configuration information

Get the configuration infomation, follow this:

KafkaConfiguration configuration = (KafkaConfiguration) getConfiguration(KafkaConfiguration.class);
RedisConfiguration redisConfiguration = (RedisConfiguration) ConfigurationHolder.getConfiguration(RedisConfiguration.class);
ApplicationConfiguration applicationConfiguration = (ApplicationConfiguration) ConfigurationHolder.getConfiguration(ApplicationConfiguration.class);

String brokerList = configuration.get("kafka.broker.list");
String redisHost = redisConfiguration.get("redis.host");
String port = applicationConfiguration.get("cicada.port");

LOGGER.info("Configuration brokerList=[{}],redisHost=[{}] port=[{}]",brokerList,redisHost,port);

External configuration file

Configuration files can also be read in multiple environments, just add VM parameters, also ensure that the parameter name and file name are consistent.

-Dapplication.properties=/xx/application.properties
-Dkafka.properties=/xx/kakfa.properties
-Dredis.properties=/xx/redis.properties

Custom interceptor

Implement top.crossoverjie.cicada.example.intercept.CicadaInterceptor interface.

@Interceptor(value = "executeTimeInterceptor")
public class ExecuteTimeInterceptor implements CicadaInterceptor {

    private static final Logger LOGGER = LoggerBuilder.getLogger(ExecuteTimeInterceptor.class);

    private Long start;

    private Long end;

    @Override
    public boolean before(Param param) {
        start = System.currentTimeMillis();
        return true;
    }

    @Override
    public void after(Param param) {
        end = System.currentTimeMillis();

        LOGGER.info("cast [{}] times", end - start);
    }
}

Performance Test

Test Conditions: 100 threads and 100 connections ;1G RAM/4 CPU

Nearly 10W requests per second.
