1、application.properties

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driverClassName=com.mysql.jdbc.Driver
#數(shù)據(jù)庫賬號(hào)
spring.datasource.username=K4NWAGWajCMwIOpm/QUgZwh+kY+dXYaS2C8UbSQlYh7uCsxv8fPPm3j1ObQ==
#數(shù)據(jù)庫密碼
spring.datasource.password=PrV7ZKPAMsHNO+nOyUb6kg44wDdKEL8xrhrEPAv4fXFS2ijLNW044glIQ==

# DataSource
spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
spring.datasource.maxWait=60000
spring.datasource.timeBetweenEvictionRunsMillis=60000
spring.datasource.minEvictableIdleTimeMillis=300000
spring.datasource.validationQuery=SELECT 1 FROM DUAL
spring.datasource.testWhileIdle=true
spring.datasource.testOnBorrow=false
spring.datasource.testOnReturn=false
spring.datasource.poolPreparedStatements=true
spring.datasource.maxPoolPreparedStatementPerConnectionSize=20
#加上config
spring.datasource.filters=stat,wall,log4j,config
#加上config.decrypt=true;config.decrypt.key=${spring.datasource.publickey}
spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000;config.decrypt=true;config.decrypt.key=${spring.datasource.publickey}
#公鑰
spring.datasource.publickey=MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAIWtxv6jBv0l662q/T9UFnQNia92Uht929bH0BrJzSqzMoYMWffmzFdLW9Zp0xJpfER8qCGMc+3zyyPwHe0jYAcCAwEAAQ==
spring.datasource.druid.filter.config.enabled=true

2、數(shù)據(jù)源配置類

        datasource.setUrl(this.dbUrl);
        datasource.setUsername(ConfigTools.decrypt(publickey,username));
        datasource.setPassword(ConfigTools.decrypt(publickey,password));

3、附屬，加密類

import java.security.NoSuchProviderException;
import com.alibaba.druid.filter.config.ConfigTools;
public class DruidEncrypt {
public static void main(String[] args) throws Throwable, NoSuchProviderException {
    //密碼
    String password = "mypwd";
    String username = "myuseraccount";
    System.out.println("加密前的密碼:"+password);
    
    //生成秘鑰對(duì)
    String [] keyPair = ConfigTools.genKeyPair(512);
    //私鑰
    String privateKey = keyPair[0];
    //公鑰
    String publicKey = keyPair[1];
    
    //用私鑰加密后的密文
    username = ConfigTools.encrypt(privateKey, username);
    password = ConfigTools.encrypt(privateKey, password);
 
    System.out.println("privateKey:"+privateKey);
    System.out.println("publicKey:"+publicKey);
    System.out.println("加密后的用戶:"+username);  
    System.out.println("加密后的密碼:"+password);  
    String decryptUsername=ConfigTools.decrypt(publicKey, username);
    String decryptPassword=ConfigTools.decrypt(publicKey, password);
    System.out.println("解密后的username："+decryptUsername);
    System.out.println("解密后的password："+decryptPassword);
    
}
}
