springboot+redis

1、直接创建ide项目的话

 

maven依赖:

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis-reactive</artifactId>
</dependency>

　　

pom.xml

# 应用名称
spring:
  application:
    name: redis

#redis配置
  redis:
    host: localhost
    port: 6379
    database: 0



# 应用服务 WEB 访问端口
server:
  port: 8080

 

RedisConfig  配置文件

package com.config;

import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
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.Jackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

import java.net.UnknownHostException;

@Configuration
public class RedisConfig {
    @Bean
    @SuppressWarnings("all")
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException {
        // 自定义 String Object
        RedisTemplate<Object, Object> template = new RedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);

        // Json 序列化配置
        Jackson2JsonRedisSerializer<Object> objectJackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<Object>(Object.class);
        // ObjectMapper 转译
        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        objectJackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // String 的序列化
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        // key 采用String的序列化方式
        template.setKeySerializer(stringRedisSerializer);
        // hash 的key也采用 String 的序列化方式
        template.setHashKeySerializer(stringRedisSerializer);
        // value 序列化方式采用 jackson
        template.setValueSerializer(objectJackson2JsonRedisSerializer);
        // hash 的 value 采用 jackson
        template.setHashValueSerializer(objectJackson2JsonRedisSerializer);
        template.afterPropertiesSet();

        return template;
    }
}

 

 

调用使用

package com;

import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;

import java.util.HashMap;


@SpringBootTest
class RedisApplicationTests {

    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    void contextloads(){
////        删除key
//        redisTemplate.delete("foo222");
        HashMap<String, String> Sites = new HashMap<String, String>();
// 添加键值对
        Sites.put("1", "Google");
        Sites.put("2", "Runoob");
        Sites.put("3", "Taobao");
//        Sites.put(4, "Zhihu");
        System.out.println(Sites);

        redisTemplate.opsForHash().putAll("kkk2", Sites);

    }

 

redisTemplate API调用方法
