数据库密码加密：

数据库密码加密：

1、配置jar包

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.2.8</version>
</dependency>

2、生成密码

在本地找到jar包所处目录，如：

打开cmd，定位到所在目录，执行指令：java -cp druid-1.0.26.jar com.alibaba.druid.filter.config.ConfigTools 你的密码（示例为password）：

Microsoft Windows [版本 6.3.9600]

3、修改配置

此时获取到公钥publicKey，私钥privateKey，以及密码password，将加密的password填入publicKey分别填入druid的配置中

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driverClassName: com.mysql.cj.jdbc.Driver
    druid:
      url: jdbc:mysql://localhost:3306/boost-admin?serverTimezone=Asia/Shanghai&characterEncoding=UTF-8&useSSL=false
      username: root
      password: QImPIH1+jPtqz7fBEFWl3iXngrmbA8m+n/djyvWuE0OJQXOuvQPJGe8/BqLNn3NO7HioBWNX+XpjbgbaDNSJmw==
      # encrypt config
      filters: config
      connect-properties:
        config.decrypt: true
        config.decrypt.key: MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAO46RHV8MLaC0A1sw15q8dNxBurEmgHwFVP1AvA+3+2mKdDL4uzg7tlM1JdgTjV4QOQ79bs8ba1L4ao2I1vvFR8CAwEAAQ==

mybatis:
  mapperLocations: classpath:mapper/*.xml
  typeAliasesPackage: com.heartsuit.springbootmybatis.oa.entity
  configuration:
    map-underscore-to-camel-case: true
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

数据库密码解密：

1. 创建一个测试类(DruidTest)写main方法，继承druid中的DruidPasswordCallback类。
2. 在main方法中引用ConfigTools.decrypt(publickey, password)方法，填入已知的公钥和密码。
3. 打印结果，看是否与上述明文密码一致

   package test;
   
   import com.alibaba.druid.filter.config.ConfigTools;
   import com.alibaba.druid.util.DruidPasswordCallback;
   
   
   /**

    * @version V1.0 
    */  
   public class DruidTest extends DruidPasswordCallback 
   
       public static void main(String[] args) throws Exception 
   	String publickey = "MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAO46RHV8MLaC0A1sw15q8dNxBurEmgHwFVP1AvA+3+2mKdDL4uzg7tlM1JdgTjV4QOQ79bs8ba1L4ao2I1vvFR8CAwEAAQ==";
   	String password = "QImPIH1+jPtqz7fBEFWl3iXngrmbA8m+n/djyvWuE0OJQXOuvQPJGe8/BqLNn3NO7HioBWNX+XpjbgbaDNSJmw==";
   	String pwd = ConfigTools.decrypt(publickey, password);
   
   	System.out.println(pwd);
