springboot2.0.1（目前最新版本）整合redis叢集和多索引庫solr，同時將redis叢集作mybatis的二級快取

WoddenFish發表於2018-05-10

springboot2.0.1版本相對之前的版本來說有較大的改動，所以在配置的時候不太一樣。

7.redis作mybatis二級快取工具類

import javax.annotation.PostConstruct;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import redis.clients.jedis.JedisCluster;

/**

@Component
public class JedisUtils {
	
	@Autowired
	public JedisCluster jedisCluster;
	
	private static String PREFIX="FX2_CACHE";
	
	private static JedisUtils jedisUtils;
	
	@PostConstruct
	public void init() {
		jedisUtils=this;
		jedisUtils.jedisCluster=this.jedisCluster;
	}
	
	public static void set(Object key, Object value) {
		try {
			jedisUtils.jedisCluster.hset(SerializingUtils.serialize(PREFIX),SerializingUtils.serialize(key), SerializingUtils.serialize(value));
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public static Object get(Object key) {
		try {
			byte[] keyBytes = SerializingUtils.serialize(key);

				return SerializingUtils.deserialize(jedisUtils.jedisCluster.hget(prefixBytes,keyBytes));
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		return null;
	}

	public static void del(Object key) {
		try {
			byte[] prefixBytes = SerializingUtils.serialize(PREFIX);
			jedisUtils.jedisCluster.hdel(prefixBytes,SerializingUtils.serialize(key));
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public static void clear() {
		byte[] prefixBytes = SerializingUtils.serialize(PREFIX);
		jedisUtils.jedisCluster.del(prefixBytes);
	}

	public static int getSize() {
		return jedisUtils.jedisCluster.dbSize().intValue();
	}
}

8.二級快取實現cache類

import java.util.concurrent.locks.ReadWriteLock;  

import org.apache.ibatis.cache.Cache;  
import org.apache.ibatis.cache.CacheException;  
  
import cn.fx2.utils.JedisUtils;
/**
 * Title:      MybatisRedisCache

 */
/** 
 * Cache為快取介面,給快取供應商的SPI(Service Provider Interface) 
 * Cache介面的實現類必須有一個具有String型別引數的構造方法，該引數作為實現類物件的id，對其進行唯一標識 
 */  
public class MybatisRedisCache implements Cache {  
  
    private String id;  
  
    public MybatisRedisCache(String id) {  
        this.id = id;  
    }  
  
    /** 
     * 清空快取 
     */  
    @Override  
    public void clear() {  
        JedisUtils.clear();  
    }  
  
    /** 
     * 獲取快取物件的唯一標識 
     */  
    @Override  
    public String getId() {  
        return this.id;  
    }  
  
    /** 
     * 從快取物件中獲取key對應的value 
     */  
    @Override  
    public Object getObject(Object key) {  
        return JedisUtils.get(key);  
    }  
  
    /** 
     * 獲取讀寫鎖 可選的方法，從3.2.6起這個方法不再被框架核心呼叫 任何需要的鎖，都必須由快取供應商提供 
     */  
    @Override  
    public ReadWriteLock getReadWriteLock() {  
  
        return null;  
    }  
  
    /** 
     * 獲取快取物件中儲存的鍵/值對的數量 可選的方法，沒有被框架核心呼叫 
     */  
    @Override  
    public int getSize() {  
        return JedisUtils.getSize();  
    }  
  
    /** 
     * 儲存key/value到快取物件中 key可以是任何物件 
     */  
    @Override  
    public void putObject(Object key, Object value) {  
        JedisUtils.set(key, value);  
    }  
  
    /** 
     * 可選的方法，沒有被核心框架呼叫，移除key對應的value 
     */  
    @Override  
    public Object removeObject(Object key) {  
  
        return null;  
    }  
  
    /** 
     * 重新equals方法 
     */  
    @Override  
    public boolean equals(Object o) {  
        if (getId() == null)  
            throw new CacheException("Cache instances require an ID.");  
        if (this == o)  
            return true;  
        if (!(o instanceof Cache))  
            return false;  
  
        Cache otherCache = (Cache) o;  
        return getId().equals(otherCache.getId());  
    }  
  
    /** 
     * 重新hashCode方法 
     */  
    @Override  
    public int hashCode() {  
        if (getId() == null)  
            throw new CacheException("Cache instances require an ID.");  
        return getId().hashCode();  
    }  
  
}

9.序列化redis的鍵值對工具類(將object型別資料轉換為位元組存入redis)

import java.io.ByteArrayInputStream;  
import java.io.ByteArrayOutputStream;  
import java.io.IOException;  
import java.io.ObjectInputStream;  
import java.io.ObjectOutputStream;  
/**
 * Title:      SerializingUtils
 * @author:    gdq
 * @date       2018年5月10日
 * @version    V1.0
 * Description: redis序列化
 */
public class SerializingUtils {  
      
    public static byte[] serialize(Object obj) {  
        ByteArrayOutputStream bos = null;  
        ObjectOutputStream out = null;  
        try {  
            bos = new ByteArrayOutputStream();  
            out = new ObjectOutputStream(bos);  
            out.writeObject(obj);  
            out.flush();  
        }  
        catch (IOException e) {  
            e.printStackTrace();  
        }finally {  
            try {  
                if(out!=null)out.close();  
            }catch (IOException e) {  
                e.printStackTrace();  
            }  
        }  
        return bos.toByteArray();  
    }  
      
    public static Object deserialize(byte[] data) {  
        ObjectInputStream in = null;  
        Object obj = null;  
        try {  
            ByteArrayInputStream byteIn = new ByteArrayInputStream(data);  
            in = new ObjectInputStream(byteIn);  
            obj = in.readObject();  
        }catch (Exception e) {  
            e.printStackTrace();  
        }finally {  
            try {  
                if(in!=null)in.close();  
            }catch (IOException e) {  
                e.printStackTrace();  
            }  
        }  
        return obj;  
    }  
      
}

10.測試:

import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

import org.apache.solr.client.solrj.SolrClient;
import org.apache.solr.client.solrj.SolrQuery;

		QueryResponse response = null;
		try {
			response = solrClient.query("collection1", query);//solr多索引庫操作只需要變換第一個引數（索引庫名字）即可
		} catch (SolrServerException e) {

		}
		SolrDocumentList results = response.getResults();
