Druid數據庫密碼加密

1 Druid官方提供的數據庫密碼加密

1.1執行命令加密數據庫密碼

在命令行中執行如下命令：

java -cp druid-1.0.16.jar com.alibaba.druid.filter.config.ConfigTools you_password

1.2 配置數據源，提示Druid數據源需要對數據庫密碼進行解密。

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
     init-method="init" destroy-method="close">
     <property name="url" value="jdbc:derby:memory:spring-test;create=true" />
     <property name="username" value="sa" />
     <property name="password" value="${password}" />
     <property name="filters" value="config" />
     <property name="connectionProperties" value="config.decrypt=true;config.decrypt.key=${publickey}" />
</bean>

 

1.3 配置參數，讓ConfigFilter解密密碼

有三種方式配置：
1) 可以在配置文件my.properties中指定config.decrypt=true 
2) 也可以在DruidDataSource的ConnectionProperties中指定config.decrypt=true 
3) 也可以在jvm啟動參數中指定-Ddruid.config.decrypt=true 

2. 自定義數據庫密碼加密方法

1. 實現DBPasswordCallback

package com.netposa.security;

import com.alibaba.druid.util.DruidPasswordCallback;
import org.apache.commons.lang3.StringUtils;

import java.util.Properties;

/**
 * Created by Administrator on 2016/11/7.
 */
public class DBPasswordCallback extends DruidPasswordCallback {
    @Override
    public void setProperties(Properties properties) {
        super.setProperties(properties);
        String pwd = properties.getProperty("password");
        if (StringUtils.isNoneBlank(pwd)) {
            try {
                //這里的password是將jdbc.properties配置得到的密碼進行解密之后的值
                //所以這里的代碼是將密碼進行解密
                //TODO 將pwd進行解密;
                String password = decrypt(pwd);
                setPassword(password.toCharArray());
            } catch (Exception e) {
                setPassword(pwd.toCharArray());
            }
        }
    }

    private String decrypt(String src)
    {
       //解密
    }
}

2、配置Druid的數據庫連接池

<bean id="dbPasswordCallback" class="com.netposa.security.DBPasswordCallback" lazy-init="true"/>

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" destroy-method="close">
        <property name="driverClassName" value="${datasource.jdbc.driver}"/>
        <property name="url" value="${datasource.jdbc.url}"/>
        <property name="username" value="${datasource.jdbc.username}"/>
        <property name="password" value="${datasource.jdbc.password}"/>

        <property name="passwordCallback" ref="dbPasswordCallback"/>
        <property name="connectionProperties" value="password=${datasource.jdbc.password}" />

 

 

 

<property name="passwordCallback" ref="dbPasswordCallback"/>

<property name="connectionProperties" value="password=${datasource.jdbc.password}" />

 

${datasource.jdbc.password}為加密后的密碼
