Disruptor的开发应用

        工作时遇到更新大量数据问题简单应用了一下Disruptor。Disruptor被称为一个并发框架，但主要是一个数据队列，想要掌握它，应先学习线程容器：BlockingQueue等知识 ,并清晰的认识:多个生产者---队列---多个消费者的模式。1导jar包2 创建一个基本的包装类`package vinux.web.openApi.controller;

import java.util.List;
import java.util.Map;

import vinux.service.dao.VinuxCenterMemberSellerMapper;
import vinux.service.entity.VinuxCenterMemberSeller;

public class Element {

private  VinuxCenterMemberSellerMapper sellerMapper;private List<VinuxCenterMemberSeller> mdcList ;private Integer type;private Map<String, Object> params;public VinuxCenterMemberSellerMapper getSellerMapper() {    return sellerMapper;}public void setSellerMapper(VinuxCenterMemberSellerMapper sellerMapper) {    this.sellerMapper = sellerMapper;}public List<VinuxCenterMemberSeller> getMdcList() {    return mdcList;}public void setMdcList(List<VinuxCenterMemberSeller> mdcList) {    this.mdcList = mdcList;}public Integer getType() {    return type;}public void setType(Integer type) {    this.type = type;}public Map<String, Object> getParams() {    return params;}public void setParams(Map<String, Object> params) {    this.params = params;}

}
3这是一个添加到队列的类package vinux.web.openApi.controller;

import java.util.List;
import java.util.Map;

import vinux.service.dao.VinuxCenterMemberSellerMapper;
import vinux.service.entity.VinuxCenterMemberSeller;

public class Element {

private  VinuxCenterMemberSellerMapper sellerMapper;private List<VinuxCenterMemberSeller> mdcList ;private Integer type;private Map<String, Object> params;public VinuxCenterMemberSellerMapper getSellerMapper() {    return sellerMapper;}public void setSellerMapper(VinuxCenterMemberSellerMapper sellerMapper) {    this.sellerMapper = sellerMapper;}public List<VinuxCenterMemberSeller> getMdcList() {    return mdcList;}public void setMdcList(List<VinuxCenterMemberSeller> mdcList) {    this.mdcList = mdcList;}public Integer getType() {    return type;}public void setType(Integer type) {    this.type = type;}public Map<String, Object> getParams() {    return params;}public void setParams(Map<String, Object> params) {    this.params = params;}

}
4package vinux.web.openApi.controller;

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import vinux.service.dao.VinuxCenterMemberSellerMapper;
import vinux.service.entity.VinuxCenterMemberSeller;

import com.lmax.disruptor.EventHandler;
import com.lmax.disruptor.WorkHandler;
/**
*
* updateProductWhereC_PRODUCT_COUNT\\
*
* dayStartTime
*
* dayEndTime
* */
public class Handler1 implements EventHandler, WorkHandler {

@Overridepublic void onEvent(Element event) throws Exception {    try {        SimpleDateFormat myFmt1=new SimpleDateFormat("yyyy-MM-dd");         Map<String, Object> params = new HashMap<String, Object>();         VinuxCenterMemberSellerMapper sellerMapper = event.getSellerMapper();        List<VinuxCenterMemberSeller> mdcList = event.getMdcList();        for (VinuxCenterMemberSeller vinuxCenterMemberSeller : mdcList) {            Date calculateDate = vinuxCenterMemberSeller.getCalculateDate();            String format = myFmt1.format(calculateDate);            params.put("dayStartTime", format+" 00:00:00");            params.put("dayEndTime", format+" 23:59:59");            params.put("id", vinuxCenterMemberSeller.getUserId());            sellerMapper.updateProductWhereC_PRODUCT_COUNT(params);        }    } catch (Exception e) {        e.printStackTrace();    }}   @Overridepublic void onEvent(Element event, long arg1, boolean arg2) throws Exception {    this.onEvent(event);  }

}
这里可以看成一个Service 5disruptor的配置和调用 Map
