java spring boot 部署redis
1 先下载依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency>
2 弄下配置环境
#编码格式 spring.http.encoding.force=true spring.http.encoding.charset=UTF-8 spring.http.encoding.enabled=true server.tomcat.uri-encoding=UTF-8 #redis配置 #Redis服务器地址 spring.redis.host=127.0.0.1 #Redis服务器连接端口 spring.redis.port=6379 #Redis数据库索引(默认为0) spring.redis.database=0 #连接池最大连接数(使用负值表示没有限制) spring.redis.jedis.pool.max-active=50 #连接池最大阻塞等待时间(使用负值表示没有限制) spring.redis.jedis.pool.max-wait=3000 #连接池中的最大空闲连接 spring.redis.jedis.pool.max-idle=20 #连接池中的最小空闲连接 spring.redis.jedis.pool.min-idle=2 #连接超时时间(毫秒) spring.redis.timeout=5000
3 弄个redis封装类
package com.example.demo2122; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.stereotype.Component; /** * redis操作工具类.</br> * (基于RedisTemplate) * @author xcbeyond * 2018年7月19日下午2:56:24 */ @Component public class RedisUtils { @Autowired private RedisTemplate<String, String> redisTemplate; /** * 读取缓存 * * @param key * @return */ public String get(final String key) { return redisTemplate.opsForValue().get(key); } /** * 写入缓存 */ public boolean set(final String key, String value) { boolean result = false; try { redisTemplate.opsForValue().set(key, value); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * 更新缓存 */ public boolean getAndSet(final String key, String value) { boolean result = false; try { redisTemplate.opsForValue().getAndSet(key, value); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } /** * 删除缓存 */ public boolean delete(final String key) { boolean result = false; try { redisTemplate.delete(key); result = true; } catch (Exception e) { e.printStackTrace(); } return result; } }
4 测试
package com.example.demo2122; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.RestController; import javax.annotation.Resource; import java.util.*; @RestController public class HelloControl { @Resource private RedisUtils redisUtils; @GetMapping("/hello") public String hello(@RequestParam(value = "name", defaultValue = "World") String name) { redisUtils.set("redis_key", "redis_vale"); String value = redisUtils.get("redis_key"); return value; } }
