Spring Boot系列教程九：Spring boot集成Redis

一.创建项目

    项目名称为 “springboot_redis”，创建过程中勾选 “Web”，“Redis”，第一次创建Maven需要下载依赖包(耐心等待)

二.实现

properties配置文件中添加配置信息

##########redis############

#redis的IP地址
spring.redis.host=localhost  
#redis的端口
spring.redis.port=6379
#redis的密码
spring.redis.password=123456
#redis默认有16个数据库，使用DB0
spring.redis.database=0

创建RedisComponent类

package com.woniu.RedisComponent;

import org.apache.hadoop.mapred.gethistory_jsp;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Component;


@Component
public class RedisComponent {
    @Autowired
    private StringRedisTemplate stringRedisTemplate;
    
    public void set(String key, String value){
        ValueOperations<String, String> ops = this.stringRedisTemplate.opsForValue();
        boolean bExistent = this.stringRedisTemplate.hasKey(key);
        if (bExistent) {
            System.out.println("this key is bExistent!");
        }else{
            ops.set(key, value);
        }
    }
    
    public String get(String key){
        return this.stringRedisTemplate.opsForValue().get(key);
    }
    
    public void del(String key){
        this.stringRedisTemplate.delete(key);
    }
}

创建WebController类

package com.woniu.controller;

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

import com.woniu.RedisComponent.RedisComponent;

@RestController
@RequestMapping(value="/web")
public class WebController {
    
    @Autowired
    private RedisComponent redisComponet;
    
    @RequestMapping(value="/set/{key}/{value}")
    public String set(@PathVariable String key, @PathVariable String value){
        redisComponet.set(key, value);
        return "set key succ!";
    }
    
    @RequestMapping(value="/get/{key}")
    public String get(@PathVariable String key){
        return redisComponet.get(key);
    }
    
    @RequestMapping(value="/del/{key}")
    public void del(@PathVariable String key){
        redisComponet.del(key);
    }
}

本机安装redis，设置密码为123456，启动redis。
