Spring MVC使用Lettuce框架连接Redis

Maven

pom.xml

<!--redis-->
<!--spring支持-->
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-redis</artifactId>
    <version>2.1.6.RELEASE</version>
</dependency>
<!--连接框架-->
<dependency>
    <groupId>io.lettuce</groupId>
    <artifactId>lettuce-core</artifactId>
    <version>5.1.4.RELEASE</version>
</dependency>
<!--连接池-->
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-pool2</artifactId>
    <version>2.6.0</version>
</dependency>

使用注解方式添加Bean

import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisPassword;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.connection.lettuce.LettucePoolingClientConfiguration;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

import java.time.Duration;

@Configuration
@EnableWebMvc
public class RedisConnectionFactory {

    /**
     * Redis 连接配置
     * @return
     */
    @Bean(name = "stringRedisTemplate")
    public StringRedisTemplate init() {
        GenericObjectPoolConfig poolConfig;//连接池
        LettucePoolingClientConfiguration poolingClientConfiguration;//lettuce连接池配置
        RedisStandaloneConfiguration standaloneConfiguration;//spring redis 配置
        LettuceConnectionFactory lettuceConnectionFactory;//lettuce 连接工厂
        StringRedisTemplate stringRedisTemplate;//redis 操作类
        // 连接池
        poolConfig = new GenericObjectPoolConfig();
        poolConfig.setMaxIdle(100);
        poolConfig.setMaxTotal(100);
        poolConfig.setMaxWaitMillis(Duration.ofMinutes(1).toMillis());
        // 连接客户端配置
        poolingClientConfiguration = LettucePoolingClientConfiguration.builder()
                .poolConfig(poolConfig)
                .build();
        // 连接配置
        standaloneConfiguration = new RedisStandaloneConfiguration("127.0.0.1", 6379);//端口和地址
        standaloneConfiguration.setPassword(RedisPassword.none());// 这里的redis没有设置密码
        standaloneConfiguration.setDatabase(0);//默认选第一个数据库
        // 连接工厂
        lettuceConnectionFactory = new LettuceConnectionFactory(standaloneConfiguration, poolingClientConfiguration);
        // 记得应用设置
        lettuceConnectionFactory.afterPropertiesSet();
        // 已经默认了序列化为UTF-8的字符串序列化
        stringRedisTemplate = new StringRedisTemplate(lettuceConnectionFactory);
        return stringRedisTemplate;
    }
}

最后不要忘了在spring的配置文件里面配置包的扫描路径

<context:component-scan base-package="com.example"/>
