easyExcel如何实现

package com.zh.oukele.listener;

import com.alibaba.excel.context.AnalysisContext;
import com.alibaba.excel.event.AnalysisEventListener;
import com.zh.oukele.model.ExcelMode;

import java.util.ArrayList;
import java.util.List;

/***
 *  监听器
 */
public class ExcelModelListener extends AnalysisEventListener<ExcelMode> {

    /**
     * 每隔5条存储数据库，实际使用中可以3000条，然后清理list ，方便内存回收
     */
    private static final int BATCH_COUNT = 5;
    List<ExcelMode> list = new ArrayList<ExcelMode>();
    private static int count = 1;
    @Override
    public void invoke(ExcelMode data, AnalysisContext context) {
        System.out.println("解析到一条数据:{ "+ data.toString() +" }");
        list.add(data);
        count ++;
        if (list.size() >= BATCH_COUNT) {
            saveData( count );
            list.clear();
        }
    }

    @Override

        saveData( count );
        System.out.println("所有数据解析完成！");
        System.out.println(" count ：" + count);
    }

     * 加上存储数据库
     */
