解密Druid配置加密后的密码

在公司项目中第一次接触Druid连接池，之前一直连接的阿里云数据库服务器，没觉着与其他的连接池有啥不同，今天想改连本地数据库时报错

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sqlSessionFactory' defined in class path resource [config/spring/spring-applicationContext.xml]: Cannot resolve reference to bean 'dataSource' while setting bean property 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [config/spring/spring-applicationContext.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Failed to decrypt.

无法解密！

以下是我在jdbc.properties文件中修改三个参数：

jdbc.url=jdbc:mysql://localhost:3306/cq_tax_getsjtest?relaxAutoCommit=true&useUnicode=true&characterEncoding=UTF-8&characterSetResults=UTF-8&zeroDateTimeBehavior=convertToNull&autoReconnect=true&failOverReadOnly=false
jdbc.username=root
jdbc.password=hs282314

由于Druid提供了数据库密码加密的功能，并且在配置文件中开启Druid的监控统计功能（druid.filters=config,wall,log4j）与数据库密码解密功能（druid.connectionProperties=config.decrypt=true;config.decrypt.key=xxx），所以需要对数据库密码加密，下面介绍加密步骤：

1.找到druid-1.0.18.jar包

2.在该路径下执行dos命令

java -cp druid-1.0.18.jar com.alibaba.druid.filter.config.ConfigTools 1234567a

（druid-1.0.18.jar:对应的jar包名称，12345678a：对应的数据库密码）

回车，

publicKey与password分别对应jdbc.properties文件中的jdbc.password与publicKey
