Druid数据库密码加密：_druid 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）：

3、如果你想使用存在的密钥，可以通过如下方式得到加密后的密码：

package test;
 
import com.alibaba.druid.filter.config.ConfigTools;
import com.alibaba.druid.util.DruidPasswordCallback;
 
 
/**  
 * @Description:    Druid加解密(用一句话描述该文件做什么)

 */  
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);
    }
}
