前期准备

• 创建Spring Boot 工程
  
  

......

---

• Maven 加入必要的依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
    <version>1.5.7.RELEASE</version>
</dependency>

---

• application.properties

spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.password=123456
spring.redis.database=0
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=500
spring.redis.pool.min-idle=0
spring.redis.timeout=0

---

• 启动redis

---

连接redis做相应的数据操作

查看源码可知 redisTemplate 和 StringRedisTemplate已被自动配置，所以我们直接用就可以

org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration.class

---

---

RedisDao.java

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.Repository;

@Repository
public class RedisDao {

    @Autowired
    private StringRedisTemplate template;

    public  void setKey(String key,String value){
        ValueOperations<String, String> ops = template.opsForValue();
        ops.set(key,value);
    }

    public String getValue(String key){
        ValueOperations<String, String> ops = this.template.opsForValue();
        return ops.get(key);
    }
}

---

RedisController.java

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

import com.dao.RedisDao;

@RestController
public class RedisController {
    @Autowired
    private RedisDao redisDao;

    @RequestMapping("/set")
    public String set(String key,String value){
        redisDao.setKey(key, value);
        return "success";
    }
    @RequestMapping("/get")
    public String get(String key){
        return redisDao.getValue(key);
    }
}
