SpringBoot连接reids cluster集群（炒鸡简单）

简单讲两句

• 我这里用的springBoot 的版本为 2.2.1.RELEASE
• 搭建redis cluster集群的方法见：点我
• 我的项目直接使用Idea的模板自动生成的

开干，直接贴代码了

• pom.xml （就这两个依赖）

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

• application.properties （就写着一句）

spring.redis.cluster.nodes=\
  192.168.56.117:30001,\
  192.168.56.117:30002,\
  192.168.56.117:30003,\
  192.168.56.117:30004,\
  192.168.56.117:30005,\
  192.168.56.117:30006

• Java代码 （这是所有代码了）

package com.example.demo;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(DemoApplication.class, args);
    }

    private StringRedisTemplate redisTemplate;

    @Autowired
    public void setRedisTemplate(StringRedisTemplate redisTemplate) {
        this.redisTemplate = redisTemplate;
    }

    @GetMapping("/set")
    public String set(String key,String value){
        redisTemplate.opsForValue().set(key,value);
        return "OK！";
    }

    @GetMapping("/get")
    public String get(String key){
        return redisTemplate.opsForValue().get(key);
    }
}

• 记得开启集群redis的外网访问，不然死活连接不上，修改脚本文件 create-cluster，启动参数加上
  –protected-mode no --bind 192.168.56.117
