Mycat1.6.74自定义全局序列号

server.xml

	<property name="sequnceHandlerType">5</property>
	<property name="sequenceHanlderClass">io.mycat.route.sequence.handler.HttpIncrSequenceHandler</property>

sequenceHanlderClass是自定义全局序列号加载类

io.mycat.route.sequence.handler.HttpIncrSequenceHandler的配置

sequence_http_conf.properties

 

url = http://localhost:8067/

post请求的url

 

form的内容

prefixName: GLOBAL
count: 0
limit: -1

 

当count大于limit时候，才会请求服务器

count初始值为0

limiy初始值为-1

响应格式为1,2

1的位置是当前的count

2是limit的值

post实现代码

   OkHttpClient client = new OkHttpClient.Builder()
                        .build();
                RequestBody body = new FormBody.Builder()
                        .add("prefixName", prefixName)
                        .add("count",Long.toString(count))
                        .add("limit", Long.toString(limit))
                        .build();
                Request request = new Request.Builder()
                        .url(url)
                        .post(body)
                        .build();
                final Call call = client.newCall(request);

 

服务端响应参考代码

需要实现根据post的信息返回自定义响应

package cn.lightfish.describer;

import io.vertx.core.MultiMap;
import io.vertx.core.Vertx;
import io.vertx.core.http.HttpServer;

import java.util.concurrent.atomic.AtomicLong;

public class Test2 {
    public static void main(String[] args) {
        AtomicLong count = new AtomicLong(0);
        int batch = 5;
        Vertx vertx = Vertx.vertx();
        HttpServer httpServer = vertx.createHttpServer();
        httpServer.requestHandler(httpServerRequest -> {
            httpServerRequest.setExpectMultipart(true);
            httpServerRequest.endHandler(event -> {
                MultiMap entries = httpServerRequest.formAttributes();
                System.out.println(entries);
                long limit = count.addAndGet(5);
                httpServerRequest.response().setChunked(true).end(limit - batch + "," + limit);
            });
        }).listen(8067);
    }
}
