controller

package com.pj.controller;


import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/test")
public class TestController {

    @Autowired
    RedisTemplate redisTemplate;

    @GetMapping("/test")
    public void testOne() {
        redisTemplate.opsForValue().set("name","张一雄");
        String name = (String) redisTemplate.opsForValue().get("name");
        System.out.println(name);
    }

}

测试

http://localhost:8000/redis/test

发现乱码

解决乱码

新增配置类

package com.pj.config;

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.serializer.JdkSerializationRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;


@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory connectionFactory) {
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(connectionFactory);
        // 设置key和value的序列化方式
        redisTemplate.setKeySerializer(new StringRedisSerializer()); // 设置key的序列化器为StringRedisSerializer
        redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer()); // 设置value的序列化器为JdkSerializationRedisSerializer
        redisTemplate.setHashKeySerializer(new StringRedisSerializer()); // 设置hash key的序列化器为StringRedisSerializer
        redisTemplate.setHashValueSerializer(new JdkSerializationRedisSerializer()); // 设置hash value的序列化器为JdkSerializationRedisSerializer
        redisTemplate.afterPropertiesSet(); // 初始化RedisTemplate
        return redisTemplate; // 返回配置好的RedisTemplate
    }
}

在测测试

http://localhost:8000/redis/test

redis API

string

• 存自动过期的字符串

  // 10 秒过期
  redisTemplate.opsForValue().set("key","value",10,TimeUnit.SECONDS );
