我不知道为什么会这样。创建名为“jedis ConnectionFactory”的bean时出错

Question

运行应用程序后检测到错误。我找不到任何问题，我需要帮助。

包结构由config和controller组成。

package com.arthur.springbootredis.config;

import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.RedisConnectionFailureException;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.GenericToStringSerializer;

@Configuration
public class RedisConfig {

    @Bean
    JedisConnectionFactory jedisConnectionFactory() {

        JedisConnectionFactory jedisConnectionFactory = null;

        try {
            RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
            redisStandaloneConfiguration.setDatabase(0);
            redisStandaloneConfiguration.setHostName("localhost");
            redisStandaloneConfiguration.setPort(6379);

            jedisConnectionFactory = new JedisConnectionFactory(redisStandaloneConfiguration);

            jedisConnectionFactory.getPoolConfig().setMaxTotal(50);
            jedisConnectionFactory.getPoolConfig().setMaxIdle(50);
        } catch (RedisConnectionFailureException e) {
            e.getMessage();
        }

        return jedisConnectionFactory;
    }


    @Bean
    @ConditionalOnMissingBean(name = "redisTemplate")
    public RedisTemplate<String, Object> redisTemplate() {
        final RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
        template.setConnectionFactory(jedisConnectionFactory());
        template.setValueSerializer(new GenericToStringSerializer<Object>(Object.class));
        template.setEnableTransactionSupport(true);
        return template;
    }
}

您正在尝试使用Jedis3.0.x，它对Jedis2.x提供的API进行了突破性的更改。异常是由JedisConnectionFactory引发的，它是Spring Data Redis的一部分，在撰写本文时，Spring Data Redis仅支持Jedis2.x。对Jedis 3的支持已经实现，但尚未发布。如果您想使用Spring Data Redis，您应该暂时坚持使用Jedis2.x。对Jedis3.0的支持将在Spring Data Redis2.2中发布，这是Spring Data Moore发布系列的一部分，并将包含在Spring Boot2.2中。
