篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了springboot 中 RedisCacheManager rm = new RedisCacheManager(redisTemplate);我的项目没这个构造相关的知识,希望对你有一定的参考价值。
pom.xml 引入redis 开启缓存<!-- cache -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-cache</artifactId>
</dependency>
<!-- redis -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
application.properties 配置文件
# Redis数据库索引(默认为0)spring.redis.database=0
# Redis服务器地址spring.redis.host=localhost
# Redis服务器连接端口spring.redis.port=6379
# Redis服务器连接密码(默认为空)spring.redis.password=
# 连接池最大连接数(使用负值表示没有限制)
spring.redis.pool.max-active=8
# 连接池最大阻塞等待时间(使用负值表示没有限制)
spring.redis.pool.max-wait=-1
# 连接池中的最大空闲连接
spring.redis.pool.max-idle=8
# 连接池中的最小空闲连接
spring.redis.pool.min-idle=0
# 连接超时时间(毫秒)
spring.redis.timeout=0
添加cache的配置类

测试用的Controller
package www.ijava.com.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import www.ijava.com.service.RedisService;
@RestController
public class DemoController
@Autowired
private RedisService redisService ;
@RequestMapping(value = "/test")
public String demoTest()
boolean result = redisService.set("1","value22222");
Object object = redisService.get("1");
Object name = redisService.get("name");
System.out.println(object);
return result+"-------"+object+" ---"+name;
使用Redis-cli客户端查看 参考技术A springboot 2.x之后没有这个构造了
