Spring Encrypted DRUID Connection pool (ii)--encryption url,driverclassname, username, password

Why?

The connection information is exposed to the risk in the configuration file

How?

First, ready to encrypt after connection information

Encrypt connection information using Druid Self-tool class Configtools

ImportCom.alibaba.druid.filter.config.ConfigTools; Public classDecryptdruid { PublicDecryptdruid () {Super(); //TODO auto-generated Constructor stub    }     Public Static voidMain (string[] args) {Decryptdruid DP=NewDecryptdruid (); String[] Myuserpass={Url,driverclassname,username,password};  for(inti = 0;i < Myuserpass.length (); i++) {Dp.testdecrypt (Dp.testencrypt (Myuserpass)); }    }    /*** Decryption of words *@throwsException*/     Publicstring Testdecrypt (String encry) {//decryptionString word=encry; String Decryptword=""; Try{Decryptword=Configtools.decrypt (word); } Catch(Exception e) {//Todo:handle ExceptionE.printstacktrace ();        } System.out.println (Decryptword); returnDecryptword; }    /*** Text is encrypted *@throwsException*/     Publicstring Testencrypt (String userpass) {//EncryptString Encryptword = ""; Try{Encryptword=Configtools.encrypt (Userpass); } Catch(Exception e) {//Todo:handle ExceptionE.printstacktrace ();        } System.out.println (Encryptword); returnEncryptword; }}    

Decryptdruid

Second, prepare the decryption method class

Inherit Druiddatasource, override parent class connection information set method

ImportCom.alibaba.druid.filter.config.ConfigTools;ImportCom.alibaba.druid.pool.DruidDataSource; @SuppressWarnings ("Serial") Public classEncryptdruiddatasourceextendsdruiddatasource{@Override Public voidseturl (String url) {Try{URL=configtools.decrypt (URL); } Catch(Exception e) {//Todo:handle ExceptionE.printstacktrace (); }        Super. SetUrl (URL); } @Override Public voidsetdriverclassname (String driverclassname) {Try{driverclassname=Configtools.decrypt (driverclassname); } Catch(Exception e) {//Todo:handle ExceptionE.printstacktrace (); }        Super. Setdriverclassname (Driverclassname); } @Override Public voidSetusername (String username) {Try{username=Configtools.decrypt (username); } Catch(Exception e) {//Todo:handle ExceptionE.printstacktrace (); }        Super. Setusername (username); } @Override Public voidSetPassword (String password) {Try{Password=configtools.decrypt (password); } Catch(Exception e) {//Todo:handle ExceptionE.printstacktrace (); }        Super. SetPassword (password); }}

Third, change the configuration file

Adding encrypted post-connection information to a configuration file

Filters=config

Iv. Changing the DataSource configuration

<bean id= "DataSource" class= "com.**.**. Encryptdruiddatasource "destroy-method=" Close ">

Add to:

<property name= "connectionproperties" value= "config.decrypt=true;"/>

Ok!

However, configuration mybatis will have DatabaseID not found problem, if there is a solution, hope enlighten!
