redis-手写redis切片和非切片连接池并注入springboot中

spring-data整合了redispool, 并提供redisTemplate使用, 但有时需要用到shradedJedisPool, 就需要手动注入了

手写redispool并注入springboot中

1, redis配置文件

redis.properties

redis.config.ip=192.168.50.37
redis.config.port=

redis.config.maxTotal=
redis.config.maxIdle=
redis.config.maxWaitmillis=
redis.config.testOnborrow=false

2, RedisClientConfig.java, 获取spring注入的属性值

package com.iwhere.learn.redis.java;

import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.PropertySource;
import org.springframework.stereotype.Component;

/**
 * 使用一个专门的类来获取配置文件
 * @author wenbronk
 * @time 2017年4月6日  上午11:11:57  2017
 */

@Component(value="redisClientConfig")
@ConfigurationProperties(prefix = "redis.config")
@PropertySource("classpath:source/redis.properties")
public class RedisClientConfig {

    private String ip;
    private int port;
    private int maxTotal;
    private int maxIdle;
    private long maxWaitmillis;
    private boolean testOnborrow;

    public String getIp() {
        return ip;
    }
    public void setIp(String ip) {
        this.ip = ip;
    }
    public int getPort() {
        return port;
    }
    public void setPort(int port) {
        this.port = port;
    }
    public int getMaxTotal() {
        return maxTotal;
    }
    public void setMaxTotal(int maxTotal) {
        this.maxTotal = maxTotal;
    }
    public int getMaxIdle() {
        return maxIdle;
    }
    public void setMaxIdle(int maxIdle) {
        this.maxIdle = maxIdle;
    }
    public long getMaxWaitmillis() {
        return maxWaitmillis;
    }
    public void setMaxWaitmillis(long maxWaitmillis) {
        this.maxWaitmillis = maxWaitmillis;
    }
    public boolean isTestOnborrow() {
        return testOnborrow;
    }
    public void setTestOnborrow(boolean testOnborrow) {
        this.testOnborrow = testOnborrow;
    }
}

3, RedisClientUtils, 用于生成 jedisPool 并注入spring中

package com.iwhere.learn.redis.java;

import java.util.ArrayList;

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

import redis.clients.jedis.Jedis;
import redis.clients.jedis.JedisPool;
import redis.clients.jedis.JedisPoolConfig;
import redis.clients.jedis.JedisShardInfo;
import redis.clients.jedis.ShardedJedis;
import redis.clients.jedis.ShardedJedisPool;

/**
 * 用于获取redis连接池
 *
 * @author wenbronk
 * @time 2017年3月24日 下午1:43:36 2017
 */

@Component
public class RedisClientUtil {

    @Autowired
    private RedisClientConfig redisClientConfig;

    /** 非切片连接池 */
    private JedisPool jedisPool;

    /** 切片连接池 */
    private ShardedJedisPool shardedJedisPool;

    /**
     * 初始化非切片连接池
     */
    public JedisPool getJedisPool() {
        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxTotal(redisClientConfig.getMaxTotal());
        config.setMaxIdle(redisClientConfig.getMaxIdle());
        config.setMaxWaitMillis(redisClientConfig.getMaxWaitmillis());
        config.setTestOnBorrow(redisClientConfig.isTestOnborrow());

        jedisPool = new JedisPool(config, redisClientConfig.getIp(), redisClientConfig.getPort());
        return jedisPool;
    }

    /**
     * 初始化切片连接池
     */
//    @Bean(name="shardedJedisPool")
    public ShardedJedisPool getShardedJedisPool() {
        // 池基本配置
        JedisPoolConfig config = new JedisPoolConfig();
        config.setMaxTotal(redisClientConfig.getMaxTotal());
        config.setMaxIdle(redisClientConfig.getMaxIdle());
        config.setMaxWaitMillis(redisClientConfig.getMaxWaitmillis());
        config.setTestOnBorrow(redisClientConfig.isTestOnborrow());

        ArrayList<JedisShardInfo> list = new ArrayList<JedisShardInfo>();
        list.add(new JedisShardInfo(redisClientConfig.getIp(), redisClientConfig.getPort(), "master"));

        shardedJedisPool = new ShardedJedisPool(config, list);
        return shardedJedisPool;
    }

    public JedisPool getSingleJedisPool() {
        if (jedisPool == null) {
            synchronized(RedisClientUtil.class) {
                if (jedisPool == null) {
                    return getJedisPool();
                }
            }
        }
        return jedisPool;
    }

    @Bean(name="jedis")
    public Jedis getJedis() {
        return getSingleJedisPool().getResource();
    }

//    @Bean(name="shardedJedis")
    public ShardedJedis getShardedJedis() {
        return shardedJedisPool.getResource();
    }
}

4, 引入注值所需要的依赖和注解

pom.xml中

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-configuration-processor</artifactId>
            <optional>true</optional>
        </dependency>        

入口程序中, springboot环境

package com.iwhere.learn;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.web.bind.annotation.RestController;

import com.iwhere.learn.redis.java.RedisClientConfig;
import com.iwhere.learn.redis.java.RedisClientUtil;

@RestController
@SpringBootApplication
@EnableConfigurationProperties
public class APP {

    public static void main(String[] args) {
        SpringApplication.run(APP.class, args);
    }

}

在使用redis时, 就可以通过 @Autowired 进行注入了
