redis动态切换db,没有效果

[nnnnyyyy]

redis动态切换db,代码不抛错，没有效果，一直写在db0里面.除非手动改application.properties进里面的spring.redis.database
环境:

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

代码：

package com.atguigu.rabbitmq;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;


/**

@SpringBootTest
public class TestCRedis {

    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void t2() {

        for (int i = 0; i <= 2; i++) {

            LettuceConnectionFactory connectionFactory = (LettuceConnectionFactory) this.stringRedisTemplate
                    .getConnectionFactory();

            connectionFactory.setDatabase(i);
            this.stringRedisTemplate.setConnectionFactory(connectionFactory);
            connectionFactory.resetConnection();

            ValueOperations valueOperations = this.stringRedisTemplate.opsForValue();

            valueOperations.set("test" + i, "TEST" + i);

            String test = (String) valueOperations.get("test" + i);

            System.out.println("test:" + test);
        }
    }

}

原因找到了，少了一句. 在重置db之后:connectionFactory.setDatabase(i); 需要将链接刷新:connectionFactory.afterPropertiesSet(); connectionFactory.setDatabase(i); connectionFactory.afterPropertiesSet(); connectionFactory.resetConnection();
