1.新建Spring Boot项目

添加spring-boot-starter-data-redis依赖

<dependency>

    <groupId>org.springframework.boot</groupId>

    <artifactId>spring-boot-starter-data-redis</artifactId>

</dependency>

本文会根据StringRedisTemplate、RedisTemplate这两个模板来介绍，其中StringRedisTemplate继承自RedisTemplate，只能操作键值都是String类型的数据。在实际开发中建议使用RedisTemplate<K,V>。

查询源码可知RedisTemplate默认使用JdkSerializationRedisSerializer序列化，而StringRedisTemplate则使用StringRedisSerializer。

2.配置redis

在application.properties中配置如下：

 ########################################################

 ###Redis (RedisConfiguration)

 ########################################################

 spring.redis.database=1

 spring.redis.host=127.0.0.1

 spring.redis.port=6379

 spring.redis.password=

 spring.redis.pool.max-idle=8

 spring.redis.pool.min-idle=0

 spring.redis.pool.max-active=8

 spring.redis.pool.max-wait=-1

 spring.redis.timeout=5000

3.编写代码

　　1.创建model

 package com.haq.entity;

 import java.io.Serializable;

 /**

  * Created by on 2017/2/24.

  */

 public class User implements Serializable {

     private static final long serialVersionUId = 1L;

     private String id;

     private String name;

     public User(){

         super();

     }

     public String getId() {

         return id;

     }

     public void setId(String id) {

         this.id = id;

     }

     public String getName() {

         return name;

     }

     public void setName(String name) {

         this.name = name;

     }

     @Override

     public String toString() {

         return "User{" +

                 "id='" + id + '\'' +

                 ", name='" + name + '\'' +

                 '}';

     }

 }

　　2.创建RedisService

 package com.haq.common.redis;

 import org.springframework.beans.factory.annotation.Autowired;

 import org.springframework.data.redis.core.RedisTemplate;

 import org.springframework.data.redis.core.StringRedisTemplate;

 import org.springframework.data.redis.core.ValueOperations;

 import org.springframework.stereotype.Service;

 import javax.annotation.Resource;

 /**

  * Created by on 2017/3/1.

  */

 @Service

 public class RedisService {

     @Autowired

     StringRedisTemplate stringRedisTemplate;

     @Resource(name = "stringRedisTemplate")

     ValueOperations<String, String> valOpsStr;

     @Autowired

     RedisTemplate<Object, Object> redisTemplate;

     @Resource(name = "redisTemplate")

     ValueOperations<Object, Object> valOpsObj;

     /**

      * 根据指定key获取String

      * @param key

      * @return

      */

     public String getStr(String key){

         return valOpsStr.get(key);

     }

     /**

      * 设置Str缓存

      * @param key

      * @param val

      */

     public void setStr(String key, String val){

         valOpsStr.set(key,val);

     }

     /**

      * 删除指定key

      * @param key

      */

     public void del(String key){

         stringRedisTemplate.delete(key);

     }

     /**

      * 根据指定o获取Object

      * @param o

      * @return

      */

     public Object getObj(Object o){

         return valOpsObj.get(o);

     }

     /**

      * 设置obj缓存

      * @param o1

      * @param o2

      */

     public void setObj(Object o1, Object o2){

         valOpsObj.set(o1, o2);

     }

     /**

      * 删除Obj缓存

      * @param o

      */

     public void delObj(Object o){

         redisTemplate.delete(o);

     }

 }

　　3.创建RedisController

 package com.haq.web;

 import com.haq.common.redis.RedisService;

 import com.haq.entity.User;

 import org.springframework.beans.factory.annotation.Autowired;

 import org.springframework.web.bind.annotation.RequestMapping;

 import org.springframework.web.bind.annotation.RestController;

 /**

  * Created by on 2017/3/1.

  */

 @RestController

 @RequestMapping("/redis")

 public class RedisController {

     @Autowired

     RedisService redisService;

     /**

      * 设置Str缓存

      * @param key

      * @param val

      * @return

      */

     @RequestMapping(value = "setStr")

     public String setStr(String key, String val){

         try {

             redisService.setStr(key, val);

             return "success";

         } catch (Exception e){

             e.printStackTrace();

             return "error";

         }

     }

     /**

      * 根据key查询Str缓存

      * @param key

      * @return

      */

     @RequestMapping(value = "getStr")

     public String getStr(String key){

         return redisService.getStr(key);

     }

     /**

      * 根据key产出Str缓存

      * @param key

      * @return

      */

     @RequestMapping(value = "delStr")

     public String delStr(String key){

         try {

             redisService.del(key);

             return "success";

         } catch (Exception e){

             return "error";

         }

     }

     /**

      * 设置obj缓存

      * @param key

      * @param user

      * @return

      */

     @RequestMapping(value = "setObj")

     public String setObj(String key, User user){

         try {

             redisService.setObj(key, user);

             return "success";

         } catch (Exception e){

             e.printStackTrace();

             return "error";

         }

     }

     /**

      * 获取obj缓存

      * @param key

      * @return

      */

     @RequestMapping(value = "getObj")

     public Object getObj(String key){

         return redisService.getObj(key);

     }

     /**

      * 删除obj缓存

      * @param key

      * @return

      */

     @RequestMapping(value = "delObj")

     public Object delObj(String key){

         try {

             redisService.delObj(key);

             return "success";

         } catch (Exception e){

             e.printStackTrace();

             return "error";

         }

     }

 }

4.运行测试

1.StringRedisTemplate

http://127.0.0.1:8080/redis/setStr?key=aa&val=name

http://127.0.0.1:8080/redis/getStr?key=aa

http://127.0.0.1:8080/redis/delStr?key=aa

2.RedisTemplate

http://127.0.0.1:8080/redis/setObj?key=aa&id=1&name=test

http://127.0.0.1:8080/redis/getObj?key=aa

http://127.0.0.1:8080/redis/delObj?key=aa

以上地址都能通过测试，在这里就不一一截图了

后记

可以直接使用redistemplate来保存string类型，不过使用redis client看起来就不太直观，因为JdkSerializationRedisSerializer是使用二进制形式存储数据。

最后希望大家有问题能多多指教，O(∩_∩)O谢谢
