druid给数据库登录密码加密

1.pom.xml配置

<dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.2.6</version>
        </dependency>

2.生成加密的key和加密后密码

找到druid jar包在系统的位置，打开终端，执行命令：

java -cp druid-1.2.6.jar com.alibaba.druid.filter.config.ConfigTools 123456(换成你的密码)

执行后，就会生成相应的private-key,public-key以及加密后的password,如下：

xiongzelin@xiongzelindeMacBook-Pro 1.2.6 % java -cp druid-1.2.6.jar com.alibaba.druid.filter.config.ConfigTools 123456

3.修改yml配置

spring:
  datasource:
    name: druidDataSource
    type: com.alibaba.druid.pool.DruidDataSource
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/mango?useUnicode=true&characterEncoding=utf-8
    username: root
    password: vXRaUfOWq9Fza+x1rbtNReY3HRKnQjJatk4DFKrqHcVOE6U6m+xLvArCqaPVTKbU5TLDAO0JZxrGh39BhIoDQw==
    public-key: MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAM2EOO2jvOksiiHRt2bA4kkF3zfwLKDYFdbxPaW7ASZhVV9qh3q75CnqyzzR3tYdxpIw3nR921EMzMMAfQeQ97cCAwEAAQ==
    druid:
      connection-properties: config.decrypt=true;config.decrypt.key=${spring.datasource.public-key}

在yml文件中添加public-key，修改password为加密后的密码，并在connection-properties中添加config.decrypt=true;config.decrypt.key=${spring.datasource.public-key} 来开启和应用druid密码加密
