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