7.可选安全的加密操作
数据库加密

数据库密码加密指令,cmd控制台执行 java -cp F:\server\MavenRepository\maven_jar\com\alibaba\druid\1.0.18\druid-1.0.18.jar com.alibaba.druid.filter.config.ConfigTools reiang1227 // java -cp后指向jar包,再指向com.alibaba.druid.filter.config.ConfigTools,最后加上数据库原始密码,会生成加密后的password及生成的秘钥publickey 将jdbc。properties中的数据库密码换掉,然后增加publickey参数配置 datasource.mysql.password=Je0i/vizWGnbgeYaXfuy/js/ZWeSMqnGRtjXbx/NK5pVhyUesUs91oih5W2qZpx6WzXB2ffQzByI/7K7tFlUvg== publickey=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAIliWZYPXkbi6x7hAN7y4zIGqDD3aRSJgmDhWGtrU9cbH3DExXz/BvGoA9CmEkdCGzHAOXKaz1iHw5v4EqJ/hosCAwEAAQ== |
8.访问方式
Ip:端口号/项目名/druid
