Features

Quick Start

Create a project with Maven, import core dependency.

<dependency>
    <groupId>top.crossoverjie.opensource</groupId>
    <artifactId>cicada-core</artifactId>
    <version>1.0.1</version>
</dependency>

start class:

public class MainStart {

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

Configuring business Action

Create business Action implement top.crossoverjie.cicada.server.action.WorkAction interface:

@CicadaAction(value = "demoAction")
public class DemoAction implements WorkAction {


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

    private static AtomicLong index = new AtomicLong() ;

    @Override
    public WorkRes<DemoResVO> execute(Param paramMap) throws Exception {
        String name = paramMap.getString("name");
        Integer id = paramMap.getInteger("id");
        LOGGER.info("name=[{}],id=[{}]" , name,id);

        DemoResVO demoResVO = new DemoResVO() ;
        demoResVO.setIndex(index.incrementAndGet());
        WorkRes<DemoResVO> res = new WorkRes();
        res.setCode(StatusEnum.SUCCESS.getCode());
        res.setMessage(StatusEnum.SUCCESS.getMessage());
        res.setDataBody(demoResVO) ;
        return res;
    }

}

Launch and apply access: http://127.0.0.1:7317/cicada-example/demoAction?name=12345&id=10

{
    "code": "9000",
    "dataBody": {
        "index": 1
    },
    "message": "成功"
}

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 void before(Param param) {
        start = System.currentTimeMillis();
    }

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

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

Interceptor Adapter

If you only want to implement one of the methods ,only extends top.crossoverjie.cicada.server.intercept.AbstractCicadaInterceptorAdapter abstract class.

@Interceptor(value = "loggerInterceptor")
public class LoggerInterceptorAbstract extends AbstractCicadaInterceptorAdapter {

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

    @Override
    public void before(Param param) {
        LOGGER.info("logger param=[{}]",param.toString());
    }

}

Performance Test

Test Conditions: 300 concurrency for twice ;1G RAM/one CPU/1Mbps.
