druid数据库明文密码加密

使用druid提供的com.alibaba.druid.filter.config.ConfigTools和明文密码生成私钥、公钥和加密后的密码

java -cp ${**/druid-**.jar} com.alibaba.druid.filter.config.ConfigTools ${明文密码}

**/druid-**.jar即druid的jar包

运行结果如下：

C:\Users\wukongjian>java -cp E:/workspace/Maven/repository/com/alibaba/druid/1.1.14/druid-1.1.14.jar com.alibaba.druid.filter.config.ConfigTools hello,123

1. privateKey：私钥
2. publicKey：公钥
3. password：加密后的密码

在yml配置文件中添加公钥

# 数据库密码公钥
database-password-public-key: MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAIlE2NRHPEjN1u0h9yS5fBTc2OBDAMCQiGjIXvM4q/71mXmeRc6tvMmYlO9FyamlzrYMIaySqQP3Eh5pBDwOeGsCAwEAAQ==

在yml配置文件中将原先数据库密码改为加密后的密码

spring: # spring配置
  ... ...
  datasource: # 数据源配置
    ... ...
    druid: # druid配置
      ... ...
      password: CiCmoA/LwIt2L/ND5HWVzgP0LX8Aj7UQc9i+nGjWXNcOZqet08Fr0p5x+vkEX8YNO5XQvIg5yuoj+0WLayrslA== # 加密后的密码

... ...代表其余配置

在yml配置文件中添加druid的配置

spring: # spring配置
  ... ...
  datasource: # 数据源配置
    ... ...
    druid: # druid配置
      ... ...
      filters: ... ...,config # 添加config过滤器
      connection-properties: config.decrypt=true;config.decrypt.key=${database-password-public-key};... ... # 设置需要解密和设置公钥

... ...代表其余配置

重启应用看是否可以正常使用
