spring*.xml配置文件明文加密的实现

说明：客户要求spring*.xml中Oracle/Redis/MongoDB的IP、端口、用户名、密码不能明文存放，接到需求的我，很无奈，但是还是的硬着头皮搞

系统架构：spring+mvc（Oracle是用jdbc自己封装的接口）

1.数据库配置文件加密

原xml配置

加密实现过程

思路：继承DruidDataSource，在初始化set值的时候进行解密

/**
 * 数据库连接解密
 * @author: Geoff
 * @create: 2020-12-30 16:46
 **/
public class DataBaseXml extends DruidDataSource {


  /**
   * Log4j logger
   */
  private final static Logger lg = LoggerFactory.getLogger(DataBaseXml.class);

  @Override
  public String getUrl() {
    return this.jdbcUrl;
  }

  @Override
  public void setUrl(String jdbcUrl) {
    if(GEOFF.DATA_BASE_IS_ENCRYPTION) {
      lg.info("数据库【jdbcUrl】解密初始化加载...");
      try {
        jdbcUrl = Encryption.decrypt(jdbcUrl, GEOFF.DATA_BASE_ENCRYPTION_KEY);
      } catch (Exception e) {
        lg.error("数据库【jdbcUrl】密文解密失败...");
        e.printStackTrace();
      }
    }
    this.jdbcUrl = jdbcUrl;
  }

  @Override
  public String getUsername() {
    return this.username;
  }

  @Override
  public void setUsername(String username) {
    if(GEOFF.DATA_BASE_IS_ENCRYPTION) {
      lg.info("数据库【username】解密初始化加载...");
      try {
        username = Encryption.decrypt(username, GEOFF.DATA_BASE_ENCRYPTION_KEY);
      } catch (Exception e) {
        lg.error("数据库【username】密文解密失败...");
        e.printStackTrace();
      }
    }
    this.username = username;
  }

  @Override
  public String getPassword() {
    return this.password;
  }

  @Override
  public void setPassword(String password) {
    if(GEOFF.DATA_BASE_IS_ENCRYPTION){
      lg.info("数据库【password】解密初始化加载...");
      try {
        password = Encryption.decrypt(password, GEOFF.DATA_BASE_ENCRYPTION_KEY);
      } catch (Exception e) {
        lg.error("数据库【password】密文解密失败...");
        e.printStackTrace();
      }
    }
    this.password = password;
  }



}

修改后配置文件

2.Redis配置文件加密

原配置文件

加密实现思路：由于JedisPool使用构造函数来创建，所以继承JedisPool后，在调用JedisPool构造函数的时候，调用static解密方法进行解密

import org.apache.commons.pool2.impl.GenericObjectPoolConfig;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import redis.clients.jedis.*;

/**
 * redis数据库用户名密码解密
 * @author: Geoff
 * @create: 2020-12-30 17:20
 **/
public class JedisPoolXml extends JedisPool{


  /**
   * Log4j logger
   */
  private final static Logger lg = LoggerFactory.getLogger(JedisPoolXml.class);



  public JedisPoolXml(GenericObjectPoolConfig poolConfig, String host, String port, String timeout, String password) {
    super(poolConfig,decryptHost(host),decryptPort(port),decryptTimeout(timeout),decryptPassword(password), 0, (String)null);
  }

  private JedisPoolXml(GenericObjectPoolConfig poolConfig, String host, String port,String timeout, String password, String database){
    super(poolConfig,decryptHost(host),decryptPort(port),decryptTimeout(timeout),decryptPassword(password),decryptDatabase(database));
  }


  private static String decryptHost(String host){
    if(GEOFF.DATA_BASE_IS_ENCRYPTION) {
      lg.info("Redis【host】解密初始化加载...");
      try {
        host = Encryption.decrypt(host, GEOFF.DATA_BASE_ENCRYPTION_KEY);
      } catch (Exception e) {
        lg.error("Redis【host】密文解密失败...");
        e.printStackTrace();
      }
    }
    return host;
  }

  private static int decryptPort(String port){
    if(GEOFF.DATA_BASE_IS_ENCRYPTION) {
      lg.info("Redis【port】解密初始化加载...");
      try {
        port = Encryption.decrypt(port, GEOFF.DATA_BASE_ENCRYPTION_KEY);
      } catch (Exception e) {
        lg.error("Redis【port】密文解密失败...");
        e.printStackTrace();
      }
    }
    return Integer.parseInt(port);
  }

  private static int decryptTimeout(String timeout){
    if(GEOFF.DATA_BASE_IS_ENCRYPTION) {
      lg.info("Redis【timeout】解密初始化加载...");
      try {
        timeout = Encryption.decrypt(timeout, GEOFF.DATA_BASE_ENCRYPTION_KEY);
      } catch (Exception e) {
        lg.error("Redis【timeout】密文解密失败...");
        e.printStackTrace();
      }
    }
    return Integer.parseInt(timeout);
  }

  private static String decryptPassword(String password){
    if(GEOFF.DATA_BASE_IS_ENCRYPTION) {
      lg.info("Redis【password】解密初始化加载...");
      try {
        password = Encryption.decrypt(password, GEOFF.DATA_BASE_ENCRYPTION_KEY);
      } catch (Exception e) {
        lg.error("Redis【password】密文解密失败...");
        e.printStackTrace();
      }
    }
    return password;
  }

  private static int decryptDatabase(String database){
    if(GEOFF.DATA_BASE_IS_ENCRYPTION) {
      lg.info("Redis【database】解密初始化加载...");
      try {
        database = Encryption.decrypt(database, GEOFF.DATA_BASE_ENCRYPTION_KEY);
      } catch (Exception e) {
        lg.error("Redis【database】密文解密失败...");
        e.printStackTrace();
      }
    }
    return Integer.parseInt(database);
  }

}

修改后xml

3.MongoDB配置文件加密（使用的是spring-data-mognodb框架）

原xml配置

加密思路：由于项目使用的时候是获取bean的方式来获取MongoTemplate和mongoDbFactory的，尝试过各种方法来继承后加密，但是最后都不行，后面只能通过手动的方法进行初始化，并将对应MongoTemplate和mongoDbFactory注入到bean中

import com.mongodb.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;

        e.printStackTrace();
      }
    }
    return passWord;
  }

  private String decryptDatabase(String dataBase){
    if(GEOFF.DATA_BASE_IS_ENCRYPTION) {
      lg.info("MongoDB【database】解密初始化加载...");
      try {
        dataBase = Encryption.decrypt(dataBase, GEOFF.DATA_BASE_ENCRYPTION_KEY);
      } catch (Exception e) {
        lg.error("MongoDB【database】密文解密失败...");
        e.printStackTrace();
      }
    }
    return dataBase;
  }




  public void init() {
    MongoClientOptions.Builder build = new MongoClientOptions.Builder();
    MongoClientOptions options = build.build();
    try {

修改后配置文件
