SpringBoot整合spring data Redis(掌握)

SpringBoot整合spring data Redis(掌握)

• redis-sb-demo02：pom.xml中添加redis坐标

  <!-- 配置使用redis启动器 -->
  <dependency>
  	<groupId>org.springframework.boot</groupId>
  	<artifactId>spring-boot-starter-data-redis</artifactId>
  </dependency>
  

• 配置信息

  ########################################################
  ###REDIS (RedisProperties) redis基本配置；
  ########################################################
  # database name
  spring.redis.database=0
  # server host1
  spring.redis.host=127.0.0.1
  # server password
  #spring.redis.password=
  #connection port
  spring.redis.port=6379
  # pool settings ...
  spring.redis.jedis.pool.max-idle=8
  spring.redis.jedis.pool.min-idle=0
  spring.redis.jedis.pool.max-active=8
  spring.redis.jedis.pool.max-wait=-1
  # name of Redis server
  #spring.redis.sentinel.master=
  # comma-separated list of host:port pairs
  #spring.redis.sentinel.nodes=
  

• 当SpringBoot整合SpringDataRedis之后，我们使用的对象的是RedisTemplate

第一步：pom

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- 配置使用redis启动器 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

第二步:创建UserController类

package com.youpingou.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/user")
public class UserController {

    //只需要导入springboot-data-redis的启动器，就可以使用当前这个目标，所有的初始化都由Spring帮你完成
    @Autowired
    private StringRedisTemplate stringRedisTemplate;


    @GetMapping
    public ResponseEntity<Object> testReids(){
        //存值
        stringRedisTemplate.opsForValue().set("rt","SpringBoot整合SpringDataRedis案例");
        //取值
        String school = stringRedisTemplate.opsForValue().get("school");
        System.out.println(school);
        return ResponseEntity.ok(school);
    }


}

第三步：启动测试，ok
