Redis密码在springboot中自定义加解密实践_Java

redis密码在springboot自定义加解密

1.application.yml文件配置信息

spring:
  # redis 配置
  redis:
    # 地址
    host: 192.168.1.xxx
    # 端口，默认为6379
    port: 6379
    # 数据库索引
    database: 0
    # 密码，des加密后，有key值，此处只作为例子
    password: 1e903bc217660491
    # 连接超时时间
    timeout: 10s
    lettuce:
      pool:
        # 连接池中的最小空闲连接
        min-idle: 0
        # 连接池中的最大空闲连接
        max-idle: 8
        # 连接池的最大数据库连接数
        max-active: 8
        # #连接池最大阻塞等待时间（使用负值表示没有限制）
        max-wait: -1ms

2.redisconfig中代码

package com.framework.config;
