springboot之redis-优快云博客

本文详细介绍了如何在Spring Boot项目中整合Redis缓存服务。包括在pom.xml中添加依赖，配置yml文件中的Redis参数，创建RedisConfig配置类，以及在Controller层使用StringRedisTemplate进行数据操作。

1、pom.xml文件添加依赖

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-redis</artifactId>
            <version>1.4.3.RELEASE</version>
</dependency>

2、yml文件添加redis

#默认使用配置
spring:
  profiles:
    active: @activatedProperties@
  redis:
    host: 127.0.0.1
    port: 6379
    password:
    lettuce:
      pool:
        max-active: 100
        max-idle: 10
        max-wait: 100000

3、添加配置文件RedisConfig.java

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import redis.clients.jedis.JedisPoolConfig;

@Configuration
@EnableAutoConfiguration
public class RedisConfig {

    @Bean
    @ConfigurationProperties(prefix = "spring.redis.pool")
    public JedisPoolConfig getRedisConfig(){
        JedisPoolConfig config = new JedisPoolConfig();
        return config;
    }

    @Bean
    @ConfigurationProperties(prefix = "spring.redis")
    public JedisConnectionFactory getConnectionFactory() {
        JedisConnectionFactory factory = new JedisConnectionFactory();
        factory.setUsePool(true);
        JedisPoolConfig config = getRedisConfig();
        factory.setPoolConfig(config);
        return factory;
    }

    @Bean
    public RedisTemplate<?, ?> getRedisTemplate() {
        JedisConnectionFactory factory = getConnectionFactory();
        factory.setDatabase(2); #设置保存数据的库
        RedisTemplate<?, ?> template = new StringRedisTemplate(factory);
        return template;
    }

}

4、controller层实现

@Autowired
    StringRedisTemplate redisTemplate;

    @RequestMapping("/showUser")
    @ResponseBody
    public User toIndex(HttpServletRequest request, Model model){
        int userId = Integer.parseInt(request.getParameter("id"));
        User user = this.userService.getUserById(userId);
        redisTemplate.opsForValue().set("user",user.toString());
        return user;
    }

完毕！
