【Spring Boot】使用jasypt对数据库用户名密进行加密

有时因为安全问题，在配置文件中配置的数据库用户名和密码需要进行加密处理，Spring Boot下可以使用jasypt进行加密处理

Maven导入:

<dependency>     <groupId>com.github.ulisesbocchio</groupId>     <artifactId>jasypt-spring-boot-starter</artifactId>     <version>3.0.4</version> </dependency>

 配置文件:

jasypt:   encryptor:     password: mykey     algorithm: PBEWithMD5AndDES     iv-generator-classname: org.jasypt.iv.NoIvGenerator

 数据库配置:

spring:   datasource:     driver-class-name: dm.jdbc.driver.DmDriver     url: jdbc:dm://ip:port/xxxx?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8&clobAsString=true     username: ENC(xU9yNLOa0MsHQ054swj93g==)     password: ENC(qYRUoMjLCVFceU+Ybl05E9u37wddzkhb)

 ※username和passw一定要用ENC()包起来

 

启动类注解:@EnableEncryptableProperties

加密方法: 执行方法中的main,即可得到加密后的配置参数

import org.jasypt.encryption.pbe.PooledPBEStringEncryptor;
import org.jasypt.encryption.pbe.config.SimpleStringPBEConfig;

public class JasyptUtil {

    public static void main(String[] args) {
        // 加密
        String encPwd1 = encyptPwd("mykey", "username");
        // 加密
        String encPwd2 = encyptPwd("mykey", "password");
        System.out.println(encPwd1);
        System.out.println(encPwd2);
    }
    /**
     * 加密方法
     * @param password jasypt所需要的加密密码配置
     * @param value    需要加密的密码
     */
    public static String encyptPwd(String password, String value) {
        PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
        SimpleStringPBEConfig config = new SimpleStringPBEConfig();
        config.setPassword(password);
        config.setAlgorithm("PBEWithMD5AndDES");
        config.setKeyObtentionIterations("1000");
        config.setPoolSize("1");
        config.setProviderName("SunJCE");
        config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
        config.setStringOutputType("base64");
        encryptor.setConfig(config);
        String result = encryptor.encrypt(value);
        return result;
    }
}
