利用Redis构建自定义标签（1）

（1）整体设计

 

 

 

（2）字典模块

 

 

（3）Redis模块

 

（4）加载总控线程

package com.crm.application.main;

import java.sql.Connection;
import java.sql.Statement;
import java.util.concurrent.CountDownLatch;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

import com.crm.application.load.DictionaryLoadThread;
import com.crm.h2.H2Manager;
import com.crm.h2.load.H2LoadThread;
import com.crm.redis.load.RedisLoadThread;

public class MainThread extends Thread {

	private static Log log = LogFactory.getLog(MainThread.class);

	public static final CountDownLatch mainThreadStopLatch = new CountDownLatch(1);

	@Override
	public void run() {
		log.info("-------------------------【总制线程】BEGIN-------------------------");
		
		try {
			log.info("---------------【CRM系统初始化】【01】【H2初始化】---------------");
			Connection conn = H2Manager.getConnection();
			Statement stmt = conn.createStatement();
			stmt.executeUpdate(H2Manager.getCreateCrmTranslateKindSql());
			stmt.executeUpdate(H2Manager.getCreateCrmTranslateMapSql());
			conn.close();
			new H2LoadThread().start();
			
			log.info("---------------【CRM系统初始化】【02】【字典加载】---------------");
			new DictionaryLoadThread().start();
			
			mainThreadStopLatch.await();
		} catch (Exception e) {
			e.printStackTrace();
		}
		
		log.info("---------------【CRM系统初始化】【03】【Redis缓存加载】---------------");
		// 必须等待上面的2个线程执行完成后，在执行Redis
		new RedisLoadThread().start();

		log.info("-------------------------【总制线程】END-------------------------");
	}
