SpringBoot配置Redis连接详解

1、导入Redis相关依赖

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

2、配置application.yml

server:
  port: 3060
spring:
  redis:
    host: 127.0.0.1
    port: 6379
    password: *********

3、配置config

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class ConfigRedis {
    @Autowired
    private RedisConnectionFactory redisConnectionFactory;

    @Bean
    public RedisTemplate<String, Object> redisTemplate(){
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();

        // 序列化key
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new StringRedisSerializer());

        // 序列化hash
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new StringRedisSerializer());

        // 连接redis数据库
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        return redisTemplate;
    }
}

4、UserPojo

package com.redis.start.pojo;

public class UserPojo {
    private String id;
    private String name;
    private String pwd;

    public UserPojo() {
        super();
    }

    @Override
    public String toString() {
        return "UserPojo{" +
                "id='" + id + '\'' +
                ", name='" + name + '\'' +
                ", pwd='" + pwd + '\'' +
                '}';
    }

    public UserPojo(String id, String name, String pwd) {
        this.id = id;
        this.name = name;
        this.pwd = pwd;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }
}

5、Controller

import com.redis.start.pojo.UserPojo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;
import org.springframework.web.bind.annotation.*;

import java.util.concurrent.TimeUnit;

@RestController
@RequestMapping("/redis")
@CrossOrigin
@ResponseBody
public class Controller {
    @Autowired
    private RedisTemplate<String, Object> redisTemplate;

    @GetMapping("/object")
    public String putObject(){
        UserPojo user = new UserPojo("001", "zhangSan","123456");
        // 序列化对象
        this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(UserPojo.class));
        this.redisTemplate.opsForValue().set("cookie@001", user,30, TimeUnit.SECONDS);
        System.out.print("/Object:");
        System.out.println(this.redisTemplate.opsForValue().get("cookie@001").toString());
        return "1";
    }
    @GetMapping("/list")
    public String putList(){
        this.redisTemplate.setValueSerializer(new Jackson2JsonRedisSerializer<>(UserPojo.class));
        this.redisTemplate.opsForList().leftPush("cookie@001", new UserPojo("001", "zhangSan","123456"));
        System.out.print("/List:");
        System.out.println(this.redisTemplate.opsForList().range("cookie@001", 0, -1));
        return "1";
    }
    @GetMapping(value = "/key")
    public String putKey(String key, String value){
        this.redisTemplate.opsForValue().set(key,value,30, TimeUnit.SECONDS);
        System.out.print("/Key:");
        System.out.println(this.redisTemplate.opsForValue().get(key));
        return "1";
    }

    @GetMapping("/map")
    public String putMap(){
        Map<String, String> myMap = new HashMap<>();
        myMap.put("name", "zhangSan");
        myMap.put("age", "20");
        this.redisTemplate.opsForHash().putAll("map", myMap);
        System.out.print("/Map:");
        System.out.println(this.redisTemplate.opsForHash().get("map", "name"));
        return "1";
    }

}

6、MyRedisApplicationStart启动类

package com.redis.start;

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

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

7、启动测试
