Spring Boot Redis配置示例

1. 依赖管理

在Spring Boot项目中，Redis依赖需要通过Maven仓库添加。以下是推荐的依赖配置：


   
    
    
     org.springframework.boot
    
    
    
     spring-boot-starter-data-redis
    
    
    
     2.0.0
    
    
    
        
     
            
      
       redis.clients
      
            
      
       jedis
      
        
     
        
     
            
      
       io.lettuce
      
            
      
       lettuce-core
      
        
     
    
    
   
   
    
    
     redis.clients
    
    
    
     jedis
    
    
    
     2.8.0
    
   
   
    
    
     com.alibaba
    
    
    
     fastjson
    
    
    
     1.2.47

注意：1.5版本的Spring Boot Redis依赖与2.0版本存在差异，特别是连接池技术的选择。这里使用jedis作为连接池，默认情况下会替换lettuce。

2. Redis配置

spring:
    redis:
        host: 172.30.66.104
        port: 6379
        password: 19e.com.cn
        database: 0
        jedis:
            pool:
                max-active: 5
                max-idle: 10
                min-idle: 0

3. RedisTemplate配置

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;
@Configuration
@AutoConfigureAfter(RedisAutoConfiguration.class)
public class RedisConfig {
    @Bean
    public RedisTemplate
   
     redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate
    
      template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);
        // JSON序列化
        Jackson2JsonRedisSerializer serializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper mapper = new ObjectMapper();
        mapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        mapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        serializer.setObjectMapper(mapper);
        template.setValueSerializer(serializer);
        // 字符串序列化
        template.setKeySerializer(new StringRedisSerializer());
        template.setHashKeySerializer(new StringRedisSerializer());
        template.setHashValueSerializer(serializer);
        template.afterPropertiesSet();
        return template;
    }
}

4. 测试示例

import com.qwe.common.demo.User;
import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
@SpringBootTest
public class RedisTest {
    @Autowired
    private RedisTemplate redisTemplate;
    @Test
    public void redisTest() {
        // 存储字符串
        String key = "name";
        redisTemplate.opsForValue().set(key, "qwe");
        
        // 获取字符串
        String value = (String) redisTemplate.opsForValue().get(key);
        System.out.println("key: " + key + ", value: " + value);
        // 存储对象
        User user = new User("qw", 12);
        String userKey = "qwe";
        redisTemplate.opsForValue().set(userKey, user);
        // 获取对象
        User newUser = (User) redisTemplate.opsForValue().get(userKey);
        System.out.println("key: " + userKey + ", value: " + newUser);
    }
}

以上配置和示例可根据实际项目需求进行调整，确保Redis服务器配置正确并且权限设置适当。
