SrpingBoot 2.x 整合 Redis （单机版）

本文已参与「新人创作礼」活动，一起开启掘金创作之路。​

本案例使用最新版Spring Boot 2.1.6 进行演示，2.x以后spring-boot-starter-data-redis中已经帮我们封装好。下面看使用方法。

废话不多说！！！

1，导包

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

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

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

1，添加配置文件（这里采用yml格式）

spring:
  redis:
    database: 0
    host: 192.168.1.48
    port: 6379
    password: 123456
    jedis:
      pool:
        max-active: 8
        max-wait: -1
        max-idle: 8
        min-idle: 0
    timeout: 10000

3，编写服务类

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

import java.util.Set;
import java.util.concurrent.TimeUnit;

@Component
public class RedisService {

    @Autowired
    private StringRedisTemplate stringRedisTemplate;

    public void set(String key, Object object, Long time) {
        // 存放String 类型
        if (object instanceof String) {
            setString(key, object);
        }
        // 存放 set类型
        if (object instanceof Set) {
            setSet(key, object);
        }
        // 设置有效期 以秒为单位
        stringRedisTemplate.expire(key, time, TimeUnit.SECONDS);
    }

    public void setString(String key, Object object) {
        // 如果是String 类型
        String value = (String) object;
        stringRedisTemplate.opsForValue().set(key, value);
    }

    public void setSet(String key, Object object) {
        Set<String> value = (Set<String>) object;
        for (String oj : value) {
            stringRedisTemplate.opsForSet().add(key, oj);
        }
    }

    public String getString(String key) {
        return stringRedisTemplate.opsForValue().get(key);
    }

}

4，提供web接口

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashSet;
import java.util.Set;

@RestController
public class IndexController {

    @Autowired
    private RedisService redisService;

    @RequestMapping("/setString")
    public String setString(String key, String value) {
        redisService.set(key, value, 60L);
        return "success";
    }

    @RequestMapping("/getString")
    public String getString(String key) {
        return redisService.getString(key);
    }

    @RequestMapping("/setSet")
    public String setSet() {
        Set<String> set = new HashSet<String>();
        set.add("zs");
        set.add("ls");
        redisService.setSet("setTest", set);
        return "success";
    }
}

5，访问测试

成功
