Redis密碼在springboot中自定義加解密實踐

文章介紹了在Spring?Boot項目中自定義配置Redis密碼的加解密方法,通過在`application.yml`文件中配置信息,并在`RedisConfig`類中實現(xiàn)加解密邏輯

Redis密碼在springboot自定義加解密

1.application.yml文件配置信息

spring:
  # redis 配置
  redis:
    # 地址
    host: 192.168.1.xxx
    # 端口，默認為6379
    port: 6379
    # 數(shù)據(jù)庫索引
    database: 0
    # 密碼，DES加密后，有key值，此處只作為例子
    password: 1E903BC217660491
    # 連接超時時間
    timeout: 10s
    lettuce:
      pool:
        # 連接池中的最小空閑連接
        min-idle: 0
        # 連接池中的最大空閑連接
        max-idle: 8
        # 連接池的最大數(shù)據(jù)庫連接數(shù)
        max-active: 8
        # #連接池最大阻塞等待時間（使用負值表示沒有限制）
        max-wait: -1ms

2.RedisConfig中代碼

package com.framework.config;

import com.common.utils.sign.DESUtil;

        String password = environment.getProperty("spring.redis.password");
        //解密密碼并停駕到配置中
        String pwd=DESUtil.encrypt("111111");//此處用于生成加密后的密碼，配置在配置文件中
        redisStandaloneConfiguration.setPassword(DESUtil.decrypt(password));
        return new LettuceConnectionFactory(redisStandaloneConfiguration);
    }

    @Bean

        serializer.setObjectMapper(mapper);

        // 使用StringRedisSerializer來序列化和反序列化redis的key值
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(serializer);

        template.setHashKeySerializer(new StringRedisSerializer());

        template.afterPropertiesSet();
