spring boot项目通过jasypt-spring-boot-starter加密配置Demo

1. pom.xml增加jasypt-spring-boot-starter依赖

<dependency> <groupId>com.github.ulisesbocchio</groupId> <artifactId>jasypt-spring-boot-starter</artifactId> <version>2.1.1</version> </dependency>

2.application.properties使用加密了的配置

test.datasource.username=ENC(MncHf2ANrI7ecelmdnHmzg==) test.datasource.password=ENC(vQPa96fd5XhDzpj2ktHRvQ==)

注：红色为密文

3.配置密码

可配置在application.properties文件中（这种方式不安全）

jasypt.encryptor.password=123456

在JVM启动参数中设置

-Djasypt.encryptor.password=123456

附：生成密文的工具代码

package com.example.demo;

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

public class EncryptConfigUtil {

	public static void main(String[] args) {

		String password = "123456";
		String data = "root";

		PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
		SimpleStringPBEConfig config = new SimpleStringPBEConfig();
		config.setPassword(password);
		config.setAlgorithm("PBEWithMD5AndDES");
		config.setKeyObtentionIterations("1000");
		config.setPoolSize("1");
		config.setProviderName(null);
		config.setProviderClassName(null);
		config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
		config.setIvGeneratorClassName("org.jasypt.salt.NoOpIVGenerator");
		config.setStringOutputType("base64");
		encryptor.setConfig(config);

		System.out.println(encryptor.encrypt(data));

	}

}
