SpringBoot项目集成Redis

一、在pom文件中添加依赖

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

二、在application.yml文件中配置redis

spring:
  redis:
    host: 127.0.0.1 #redis服务器IP地址
    port: 6379 #端口号
    jedis:
      pool:
        max-active: 8 #最大连接数
        max-idle: 8 #最大空闲数
        min-idle: 0 #最小空闲数
        max-wait: 30000 #最大等待时间 ms(毫秒)
    timeout: 50000 #连接超时时间 ms（毫秒）
    database: 0 #连接的数据库

三、创建RedisConfig文件

package com.ruoyi.web.core.config;
import org.springframework.cache.annotation.CachingConfigurerSupport;
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.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.JdkSerializationRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

/**
 * @ClassName RedisConfig
 * @Descrption redis序列配置
 * @Author wm
 * @Date 2020/1/11
 * @Version 1.0
 */
@Configuration
public class RedisConfig extends CachingConfigurerSupport {

    @Bean
    public RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
        //创建RedisTemplate对象
        RedisTemplate<String,Object> redisTemplate = new RedisTemplate<String,Object>();
        //设置连接工厂
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        //序列化对象
        //简单的字符串序列化
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
        //jdk序列化
        JdkSerializationRedisSerializer jdkSerializationRedisSerializer = new JdkSerializationRedisSerializer();
        //Json序列化
        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer  = new GenericJackson2JsonRedisSerializer ();
        //设置String键的序列化方式
        redisTemplate.setKeySerializer(stringRedisSerializer);
        //设置String值的序列化方式
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer);
        return redisTemplate;
    }
}

四、例子

package com.ruoyi.web.controller.test;

import org.springframework.stereotype.Component;

import java.io.Serializable;

@Component
public class Test01 implements Serializable {

    private static final long serialVersionUID = 4332651162911740406L;
    private String userName;
    private String password;
    private String phoneNum;

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getPhoneNum() {
        return phoneNum;
    }

    public void setPhoneNum(String phoneNum) {
        this.phoneNum = phoneNum;
    }
}

TestController

import com.ruoyi.zhibowei.service.attendance.IAttendRecordEmployeeStatisService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpServletRequest;
import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.TimeUnit;

/**
 * @author 
 * @description TODO
 * @create 
 */
@Controller
@RequestMapping("/test")
public class TestTestController {

    @Autowired
    private IAttendRecordEmployeeStatisService attendRecordEmployeeStatisService;
    @Autowired
    private RedisTemplate<String,Object> redisTemplate;
    @RequestMapping("/testqj")
    public void testQJAttend(){

    }


    @RequestMapping("/demo")
    @ResponseBody
    public String[] demo(HttpServletRequest request){
        List<Test01> userList = new ArrayList<Test01>();

        Test01 user1 = new Test01();
        user1.setUserName("风雅颂");
        user1.setPassword("aw916132444");
        user1.setPhoneNum("13874877512");

        Test01 user2 = new Test01();
        user2.setUserName("水雷屯");
        user2.setPassword("xf82652215");
        user2.setPhoneNum("15576758485");

        Test01 user3 = new Test01();
        user3.setUserName("天山遁");
        user3.setPassword("sd555292222");
        user3.setPhoneNum("13515114556");

        userList.add(user1);
        userList.add(user2);
        userList.add(user3);
        redisTemplate.opsForValue().set("userList",userList,60, TimeUnit.SECONDS);
        return null;
    }

    @RequestMapping(value="getValue",method={RequestMethod.GET,RequestMethod.POST})
    @ResponseBody
    public Object getValue(){
        Object object = redisTemplate.opsForValue().get("userList");
        return object;
    }

}

输出结果
