spring boot 切换redis数据库

查了很多资料都是配置文件的  公司需要随时切换数据库 所以搞了半天我的处理方式如下也许有点笨，自己根绝实际情况封装，大神请绕道

package com.rayclear;

import com.rayclear.common.RedisObjectSerializer;
import com.rayclear.domain.Users;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.List;

/**

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisTest {
    
    @Autowired
    private StringRedisTemplate stringRedisTemplate;
   
    @Autowired
    private RedisTemplate<String, Object> redisTemplate;


    @Test
    public void test() throws Exception {

        //保存对象 springboot 默认是在配置文件里初始化数据库
        Users u = new Users();
        u.setActivities_count(656);
        u.setNickname("对象名zhoushuai");
        redisTemplate.opsForValue().set("users", u);
        u = (Users) redisTemplate.opsForValue().get("users");
        System.out.println(u.getNickname());
       

         //手动改

        JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory();
        redisConnectionFactory.setHostName("127.0.0.1");  
        redisConnectionFactory.setPort(6379);
        redisConnectionFactory.setDatabase(0);
        redisConnectionFactory.afterPropertiesSet();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.opsForValue().set("zhoushuai", "hahahahhahahahhahah");
    }

}

//自己改进后的封装

/**
 * redis 数据库切换
 * @author zhoushuai
 */
public class RedisDbInit {

    
    public static RedisTemplate<String, Object> initRedis(Integer indexDb, RedisTemplate<String, Object> redisTemplate){
        JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory();
        redisConnectionFactory.setHostName("127.0.0.1");  
        redisConnectionFactory.setPort(6379);
        redisConnectionFactory.setDatabase(indexDb);
        redisConnectionFactory.afterPropertiesSet();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        return redisTemplate;
    }
}

上面测试类的方法改为

       redisTemplate = RedisDbInit.initRedis(0,redisTemplate);
        redisTemplate.opsForValue().set("new", "hahahahhahahahhahah");
        System.out.println(redisTemplate.opsForValue().get("new"));
        
        Users u2 = new Users();
        u2.setNickname("u2对象名zhoushuai");
        redisTemplate.opsForValue().set("u2", u2);
        Users users2 = (Users)redisTemplate.opsForValue().get("u2");
        System.out.println(users2.getNickname());
        
        redisTemplate = RedisDbInit.initRedis(1,redisTemplate);
        redisTemplate.opsForValue().set("u3", u2);
        Users users3 = (Users)redisTemplate.opsForValue().get("u3");
        System.out.println(users3.getNickname());
