springboot2.0整合redis

一. 简介

           redis搭建请参照笔者的另一篇文章：  linux下安装redis4.0.11

           RedisUtil的封装方法待完善......

二. 代码

2.1 pom.xml

需要引入： spring-boot-starter-data-redis 和 jackson-databind

    4.0.0

    com.example
    redisdemo
    0.0.1-SNAPSHOT
    jar

    redisdemo
    Demo project for Spring Boot

    
        org.springframework.boot
        spring-boot-starter-parent
        2.0.4.RELEASE
         
    

    
        UTF-8
        UTF-8
        1.8
    

    

        
            org.springframework.boot
            spring-boot-starter-web
        

        
            org.springframework.boot
            spring-boot-starter-test
            test
        


        
        
            org.springframework.boot
            spring-boot-starter-data-redis
        

        
        
            com.fasterxml.jackson.core
            jackson-databind
        

    

    
        
            
                org.springframework.boot
                spring-boot-maven-plugin
            
        
    

2.2 application.yml

server:
  port: 8080


# redis相关配置
spring:
  redis:
    database: 0
    host: 服务器IP
    port: 6379
    password: 密码

2.3 RedisConfig

package com.example.redisdemo.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;

/**
 * @author yuanshushu
 * @date 2018/9/1
 * @description REDIS配置类
 */
@Configuration
public class RedisConfig {

    @Bean
    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        // 使用Jackson2JsonRedisSerialize 替换默认的jdkSerializeable序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 设置value的序列化规则和 key的序列化规则
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }


}

2.4 RedisUtil(TODO 待完善)

package com.example.redisdemo.middleware;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Component;

import java.util.concurrent.TimeUnit;

/**
 * @author yuanshushu
 * @date 2018/9/1
 * @description REDIS中间件
 */
@Component
public class RedisUtil {

    @Autowired
    private RedisTemplate redisTemplate;

    /**
     * 添加字符串KEY
     *
     * @param key      字符串KEY
     * @param value    值 可以为对象
     * @param expire   过期时间
     * @param timeUnit TimeUnit中定义的时间单位
     */
    public void addKey(String key, Object value, long expire, TimeUnit timeUnit) {
        this.redisTemplate.opsForValue().set(key, value, expire, timeUnit);
    }


    /**
     * 根据KEY获取VALUE
     *
     * @param key
     * @return value
     */
    public Object getValue(String key) {
        return this.redisTemplate.opsForValue().get(key);
    }

}

2.5 启动类 

package com.example.redisdemo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class RedisdemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(RedisdemoApplication.class, args);
    }
}

2.6 测试类

package com.example.redisdemo;

import com.example.redisdemo.middleware.RedisUtil;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import java.util.concurrent.TimeUnit;

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisdemoApplicationTests {

    @Autowired
    private RedisUtil redisUtil;

    @Test
    public void contextLoads() {

        this.redisUtil.addKey("key1", "value1", 10, TimeUnit.SECONDS);

        String value1 = (String) this.redisUtil.getValue("key1");
        System.out.println(value1);
    }


}

此时可以使用redis desktop manager查看：
