### 1.创建maven工程，添加依赖，pom文件内容如下 ###

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

                </plugin>
            </plugins>
        </build>
    </project>

### 2.在文件application.properties中添加redis连接池配置 ###

# redis连接池配置
    # Redis数据库索引（默认为0）
    spring.redis.database=0
    # Redis服务器地址
    spring.redis.host=127.0.0.1
    # Redis服务器连接端口
    spring.redis.port=6379
    # Redis服务器连接密码（默认为空）
    spring.redis.password=
    # 连接池最大连接数（使用负值表示没有限制）
    spring.redis.pool.max-active=20
    # 连接池最大阻塞等待时间（使用负值表示没有限制）
    spring.redis.pool.max-wait=-1
    # 连接池中的最大空闲连接
    spring.redis.pool.max-idle=20
    # 连接池中的最小空闲连接
    spring.redis.pool.min-idle=0
    # 连接超时时间（毫秒）
    spring.redis.timeout=60000

### 3.自定义配置类RedisConfig.java ###

package com.szcatic.configuration;
    
    import org.springframework.beans.factory.annotation.Value;
    import org.springframework.context.annotation.Bean;
    import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
    import org.springframework.data.redis.connection.jedis.JedisClientConfiguration;
    import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.serializer.StringRedisSerializer;
    import org.springframework.stereotype.Component;
    
    import redis.clients.jedis.JedisPoolConfig;
    
    @Component
    public class RedisConfig {
    	
        @Value("${spring.redis.database}")
        private int database;
    
        @Value("${spring.redis.host}")
        private String host;
    
        @Value("${spring.redis.port}")
        private int port;
    
        @Value("${spring.redis.timeout}")
        private int timeout;
    
        @Value("${spring.redis.pool.max-idle}")
        private int maxIdle;
    
        @Value("${spring.redis.pool.min-idle}")
        private int minIdle;
    
        @Value("${spring.redis.pool.max-active}")
        private int maxActive;
    
        @Value("${spring.redis.pool.max-wait}")
        private long maxWait;
    	
    	private JedisConnectionFactory jedisConnectionFactory() {
    		return new JedisConnectionFactory(redisStandaloneConfiguration(), clientConfiguration());
    	}
    	
    	private RedisStandaloneConfiguration redisStandaloneConfiguration() {
    		RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration(host, port);
    		redisStandaloneConfiguration.setDatabase(database);
    		return redisStandaloneConfiguration;
    	}
    	
    	private JedisPoolConfig poolConfig() {
    		JedisPoolConfig config = new JedisPoolConfig(); 
            config.setMaxIdle(maxIdle);
            config.setMinIdle(minIdle);
            config.setMaxTotal(maxActive);
            config.setMaxWaitMillis(maxWait);
            return config;
    	}
    	
    	private JedisClientConfiguration clientConfiguration() {
    	    JedisClientConfiguration jedisClientConfiguration = JedisClientConfiguration.builder()
    	    		.usePooling()
    	            .poolConfig(poolConfig())
    	            .build();
    	    return jedisClientConfiguration;
    	}
    	
    	@Bean
    	public RedisTemplate<String, Object> redisTemplate() {
    		RedisTemplate<String, Object> template = new RedisTemplate<>();
    		template.setConnectionFactory(jedisConnectionFactory());
    		template.setKeySerializer(new StringRedisSerializer());
    		template.setHashKeySerializer(new StringRedisSerializer());
    		template.setHashValueSerializer(new StringRedisSerializer());
    		template.setValueSerializer(new StringRedisSerializer());
    		return template;
    	}
    	
    }

### 4.创建测试类RedisConfigTest.java ###

package com.szcatic.test;
    
    import java.util.List;
    
    import org.junit.jupiter.api.Test;
    import org.junit.jupiter.api.extension.ExtendWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.test.context.SpringBootTest;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.test.context.junit.jupiter.SpringExtension;
    
    import com.szcatic.Application;
    
    @Configuration
    @ExtendWith(SpringExtension.class)
    @SpringBootTest(classes = Application.class)
    public class RedisConfigTest {
    	
    	@Autowired
    	RedisTemplate<String, Object> redisTemplate;
    		
    	@Test
    	void testOpsForHash() {
    		redisTemplate.opsForHash().put("hashValue","map1","map1-1");
    		redisTemplate.opsForHash().put("hashValue","map2","map2-2");
    		List<Object> hashList = redisTemplate.opsForHash().values("hashValue");
    		System.out.println("hashList======" + hashList);
    	}
    }

### 5.启动redis单机服务，执行测试方法testOpsForHash，控制台输出结果如下 ###
