修改druid配置文件

1.修改spring.datasource.password

2.新增spring.datasource.publickey

3.修改filters，增加config

4.修改connection-properties，增加config.decrypt=true;config.decrypt.key=${spring.datasource.publicKey}

使用jvm参数进行配置

我用的是druid-1.1.6，修改druid配置没有起作用，仍然报Access Denied错误，通过断点ConfigFilter源码发现没有拿到druid配置，最终使用jvm参数方式解决。

-Ddruid.config.decrypt=true
-Ddruid.filters=config,stat,wall,log4j
-Ddruid.config.decrypt.key=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAMMcdmw/AZYSCv7s78gzR+6wC55Ir7kAUHXNZGaE9o1LG9FHbZs3n29k/DB4/fzh5ID8Tgly/lCWoluKYyaFv5kCAwEAAQ==
