Druid 数据库密码加密

DruidDruiver和DruidDataSource都支持PasswordCallback

Druid对密码的加密解密是自动实现的。

1）对用户名密码加密

java -cp D:/druid-1.0.27.jar com.alibaba.druid.filter.config.ConfigTools root

java -cp D:/druid-1.0.27.jar com.alibaba.druid.filter.config.ConfigTools 123456

执行完成以后会分别生成加密的用户密码以及对应的公钥和私钥。

2）配置DruidConfig

import com.alibaba.druid.filter.config.ConfigTools;
import com.alibaba.druid.pool.DruidDataSource;
import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import javax.servlet.Filter;
import javax.servlet.Servlet;
import javax.sql.DataSource;
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;
