Springboot如何配置Redis服务连接

配置文件

如果redis设置了密码，一定要写

spring:
  application:
    name: redis-server
    database: 1           # Redis服务器数据库
    host: 127.0.0.1  # Redis服务器地址
    port: 6379        # Redis服务器连接端口
    timeout: 6000ms       # 连接超时时间（毫秒）
    jedis:
      pool:
        max-active: 200   # 连接池最大连接数（使用负值表示没有限制）
        max-wait: -1      # 连接池最大阻塞等待时间（使用负值表示没有限制）
        max-idle: 10      # 连接池中的最大空闲连接
        min-idle: 0       # 连接池中的最小空闲连接

  implementation 'org.springframework.boot:spring-boot-starter-data-redis'
    implementation 'org.springframework.boot:spring-boot-starter-data-redis-reactive'
    implementation 'org.springframework.data:spring-data-redis:2.2.6.RELEASE'
    implementation 'org.springframework.boot:spring-boot-starter-data-redis:2.2.6.RELEASE'

Redis Config配置类

import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;

/**

 */
@Configuration
@EnableCaching
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
        redisTemplate.setConnectionFactory( factory );
        return redisTemplate;
    }

    @Bean
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory factory) {
        StringRedisTemplate stringRedisTemplate = new StringRedisTemplate();
        stringRedisTemplate.setConnectionFactory( factory );
        return stringRedisTemplate;
    }
}

函数代码

采用的是StringRedisTemplate

import com.sap.content.migrationexcel.service.RedisService;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Service;

import java.util.concurrent.TimeUnit;

/**
 * @author : Jenson.Liu
 * @date : 2020/5/14  1:43 下午
 */
@Service
public class RedisServiceImpl implements RedisService {

    private final StringRedisTemplate stringRedisTemplate;
    public static final int expire_time = 60*10*10;


    public RedisServiceImpl(StringRedisTemplate stringRedisTemplate) {
        this.stringRedisTemplate = stringRedisTemplate;
    }

    @Override
    public void setString(String key, String value) {
        stringRedisTemplate.opsForValue().set(key,value,expire_time, TimeUnit.SECONDS);
    }

    @Override
    public String getString(String key) {
        return stringRedisTemplate.opsForValue().get(key);
    }

    @Override
    public void setHash(String key, String hashKey, String hashValue) {
        stringRedisTemplate.opsForHash().put(key,hashKey,hashValue);
        stringRedisTemplate.expire(key,expire_time,TimeUnit.SECONDS);
    }

    @Override
    public String getHashValue(String key, String hashKey) {
        return stringRedisTemplate.opsForHash().get(key,hashKey).toString();
    }

    @Override
    public boolean hasKey(String key) {
        return stringRedisTemplate.hasKey(key);
    }

}
