1，redis配置
# REDIS (RedisProperties)
# 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
# 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=250
2，meven配置
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>

3，注解添加
package com.example.demo;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cache.annotation.Cacheable;
import org.springframework.stereotype.Service;
@Service
public class AccountService {
@Autowired
private AccountRepositoryaccountrepository;
@Cacheable(value="account", key ="#username")
public Account find(String username) {
System.out.println("put username in redis catch");
return accountrepository.findFirstByUsername(username);
}
public Account save (Account account) {
accountrepository.save(account);
return account;
}
}
4，继承serilizeable
package com.example.demo;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import java.io.Serializable;
@Table(name="accout")
@Entity
public class Accountimplements Serializable {
private Stringusername;
private Stringpassword;
@Id
@Column(name="USERNAME")
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
@Column(name="PASSWORD")
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String toString()
{
return "this is person:"+"name:"+this.username+"——password:"+this.password;
}
}
