1.创建maven工程，添加依赖，pom文件内容如下

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

  76.             </plugin>
  77.         </plugins>
  78.     </build>
  79. </project>

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

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

3.自定义配置类RedisConfig.java

  1. package com.szcatic.configuration;
  3. import org.springframework.beans.factory.annotation.Value;
  4. import org.springframework.context.annotation.Bean;
  5. import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
  6. import org.springframework.data.redis.connection.jedis.JedisClientConfiguration;
  7. import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
  8. import org.springframework.data.redis.core.RedisTemplate;
  9. import org.springframework.data.redis.serializer.StringRedisSerializer;
  10. import org.springframework.stereotype.Component;
  12. import redis.clients.jedis.JedisPoolConfig;
  14. @Component
  15. public class RedisConfig {
  17.     @Value("${spring.redis.database}")
  18.     private int database;
  20.     @Value("${spring.redis.host}")
  21.     private String host;
  23.     @Value("${spring.redis.port}")
  24.     private int port;
  26.     @Value("${spring.redis.timeout}")
  27.     private int timeout;
  29.     @Value("${spring.redis.pool.max-idle}")
  30.     private int maxIdle;
  32.     @Value("${spring.redis.pool.min-idle}")
  33.     private int minIdle;
  35.     @Value("${spring.redis.pool.max-active}")
  36.     private int maxActive;
  38.     @Value("${spring.redis.pool.max-wait}")
  39.     private long maxWait;
  41.     private JedisConnectionFactory jedisConnectionFactory() {
  42.         return new JedisConnectionFactory(redisStandaloneConfiguration(), clientConfiguration());
  43.     }
  45.     private RedisStandaloneConfiguration redisStandaloneConfiguration() {
  46.         RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration(host, port);
  47.         redisStandaloneConfiguration.setDatabase(database);
  48.         return redisStandaloneConfiguration;
  49.     }
  51.     private JedisPoolConfig poolConfig() {
  52.         JedisPoolConfig config = new JedisPoolConfig(); 
  53.         config.setMaxIdle(maxIdle);
  54.         config.setMinIdle(minIdle);
  55.         config.setMaxTotal(maxActive);
  56.         config.setMaxWaitMillis(maxWait);
  57.         return config;
  58.     }
  60.     private JedisClientConfiguration clientConfiguration() {
  61.         JedisClientConfiguration jedisClientConfiguration = JedisClientConfiguration.builder()
  62.                 .usePooling()
  63.                 .poolConfig(poolConfig())
  64.                 .build();
  65.         return jedisClientConfiguration;
  66.     }
  68.     @Bean
  69.     public RedisTemplate<String, Object> redisTemplate() {
  70.         RedisTemplate<String, Object> template = new RedisTemplate<>();
  71.         template.setConnectionFactory(jedisConnectionFactory());
  72.         template.setKeySerializer(new StringRedisSerializer());
  73.         template.setHashKeySerializer(new StringRedisSerializer());
  74.         template.setHashValueSerializer(new StringRedisSerializer());
  75.         template.setValueSerializer(new StringRedisSerializer());
  76.         return template;
  77.     }
  79. }

4.创建测试类RedisConfigTest.java

  1. package com.szcatic.test;
  3. import java.util.List;
  5. import org.junit.jupiter.api.Test;
  6. import org.junit.jupiter.api.extension.ExtendWith;
  7. import org.springframework.beans.factory.annotation.Autowired;
  8. import org.springframework.boot.test.context.SpringBootTest;
  9. import org.springframework.context.annotation.Configuration;
  10. import org.springframework.data.redis.core.RedisTemplate;
  11. import org.springframework.test.context.junit.jupiter.SpringExtension;
  13. import com.szcatic.Application;
  15. @Configuration
  16. @ExtendWith(SpringExtension.class)
  17. @SpringBootTest(classes = Application.class)
  18. public class RedisConfigTest {
  20.     @Autowired
  21.     RedisTemplate<String, Object> redisTemplate;
  23.     @Test
  24.     void testOpsForHash() {
  25.         redisTemplate.opsForHash().put("hashValue","map1","map1-1");
  26.         redisTemplate.opsForHash().put("hashValue","map2","map2-2");
  27.         List<Object> hashList = redisTemplate.opsForHash().values("hashValue");
  28.         System.out.println("hashList======" + hashList);
  29.     }
  30. }

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