修改proxool配置文件中密码为密文

proxool是不错的连接池，可是配置文件里数据库的密码默认是明文，感觉有点裸奔的感觉。想修改成密文。思路就是把datasource里的class设置为自己写的类，这个类继承org.logicalcobwebs.proxool.ProxoolDataSource；如：<bean id="dataSource" class="com.hclm.agency.db.DataSource">； 
在这个类里取出密码的密文，解密然后重置proxool的密码和url。上代码： 
/** * 重写org.logicalcobwebs.proxool.ProxoolDataSource * 重置数据库密码为明文 * @author Administrator * */ public class DataSource extends org.logicalcobwebs.proxool.ProxoolDataSource { /** * 重置数据库链接信息为明文 */ public void setPassword(String mi) { super.setPassword(mi); String passWord = DesDecode(mi); super.setPassword(passWord); String url = reSetUrl(super.getDriverUrl(), super.getPassword()); super.setDriverUrl(url); } /*替换url的密码为明文*/ public String reSetUrl(String url, String pwd) { int begin = url.indexOf('/'); int end = url.indexOf('@'); String url2 = url.substring(0, begin + 1) + pwd + url.substring(end); return url2; } public String getPassword() { return super.getPassword(); } /* 根据数据库配置文件密码密文得到明文 */ public String DesDecode(String mi) { DESUtil des = new DESUtil(); des.getKey("HUACAIKEYG"); String strDes = des.getDesString(mi); return strDes; } } 加密的类自己写就行了： 上示例： package com.hclm.agency.web.util; /* 字符串 DESede(3DES) 加密 */ import java.io.BufferedReader; import java.io.InputStreamReader; import java.io.UnsupportedEncodingException; import java.security.*; import javax.crypto.*; import javax.crypto.spec.SecretKeySpec; import sun.misc.BASE64Encoder; public class ThreeDes { private static final String Algorithm = "DESede"; //定义 加密算法,可用 DES,DESede,Blowfish //keybyte为加密密钥，长度为24字节 //src为被加密的数据缓冲区（源） public static byte[] encryptMode(byte[] keybyte, byte[] src) { try { //生成密钥 SecretKey deskey = new SecretKeySpec(keybyte, Algorithm); //加密 Cipher c1 = Cipher.getInstance(Algorithm); c1.init(Cipher.ENCRYPT_MODE, deskey); return c1.doFinal(src); } catch (java.security.NoSuchAlgorithmException e1) { e1.printStackTrace(); } catch (javax.crypto.NoSuchPaddingException e2) { e2.printStackTrace(); } catch (java.lang.Exception e3) { e3.printStackTrace(); } return null; } //keybyte为加密密钥，长度为24字节 //src为加密后的缓冲区 public static byte[] decryptMode(byte[] keybyte, byte[] src) { try { //生成密钥 SecretKey deskey = new SecretKeySpec(keybyte, Algorithm); //解密 // Cipher c1 = Cipher.getInstance(Algorithm); Cipher c1 = Cipher.getInstance("DESede/ECB/PKCS5Padding"); c1.init(Cipher.DECRYPT_MODE, deskey); return c1.doFinal(src); } catch (java.security.NoSuchAlgorithmException e1) { e1.printStackTrace(); } catch (javax.crypto.NoSuchPaddingException e2) { e2.printStackTrace(); } catch (java.lang.Exception e3) { e3.printStackTrace(); } return null; } //转换成十六进制字符串 public static String byte2hex(byte[] b) { String hs=""; String stmp=""; for (int n=0;n<b.length;n++) { stmp=(java.lang.Integer.toHexString(b[n] & 0XFF)); if (stmp.length()==1) hs=hs+"0"+stmp; else hs=hs+stmp; if (n<b.length-1) hs=hs+":"; } return hs.toUpperCase(); } public static void main(String[] args) { BufferedReader reader; String input ; int i=0; try{ while(true){ if(i>0){ System.out.println("<<结束请输入exit>>"); } System.out.println("请输入密码明文："); reader = new BufferedReader(new InputStreamReader(System.in)); input= reader.readLine(); // 处理控制台命令 if (input.equals("exit")){ break; }else if(input == null||input.length()<7) { System.out.println("明文字符串不能为空并且长度需要大于6"); continue; }else { i++; input = input.trim(); //添加新安全算法,如果用JCE就要把它添加进去 Security.addProvider(new com.sun.crypto.provider.SunJCE()); final byte[] keyBytes = {0x11, 0x22, 0x4F, 0x58, (byte)0x88, 0x10, 0x40, 0x38 , 0x28, 0x25, 0x79, 0x51, (byte)0xCB, (byte)0xDD, 0x55, 0x66 , 0x77, 0x29, 0x74, (byte)0x98, 0x30, 0x40, 0x36, (byte)0xE2};//24字节的密钥 try { String szSrc = input; System.out.println("加密前的字符串:" + szSrc); byte[] encoded = encryptMode(keyBytes, szSrc.getBytes()); BASE64Encoder base64en = new BASE64Encoder(); System.out.println("加密后的字符串:" + Base64.encode(encoded)); byte[] srcBytes = decryptMode(keyBytes, Base64.decode(Base64.encode(encoded))); // System.out.println("解密后的字符串:" + (new String(srcBytes))); } catch (Exception e) { // TODO Auto-generated catch block dCqB6+nmwnXOECa05SO3tA== e.printStackTrace(); } } } }catch(Exception e){ e.printStackTrace(); } } }
