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
