SpringBoot配置文件脱敏

SpringBoot集成Jasypt配置很简单，只需引入依赖，然后配置Jasypt相关属性参数即可：
● Maven

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

1、使用默认加解密方式

● 生成密文

package com.example.jasptytest;

import org.jasypt.encryption.StringEncryptor;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

@SpringBootTest
class JasptyTestApplicationTests {

	@Autowired
	StringEncryptor stringEncryptor;

	@Test
	void contextLoads() {
		final String url = stringEncryptor.encrypt("jdbc:mysql://172.16.156.158:3306/lucene?characterEncoding=utf-8&useSSL=true&serverTimezone=Asia/Shanghai");
		final String u = stringEncryptor.encrypt("wq");
		final String p = stringEncryptor.encrypt("qifeng");
		System.out.println("url: " + url);
		System.out.println("u: " + u);
		System.out.println("p: " + p);
	}

}

2、使用指定加解密方式

● 配置加解密bean

jasypt:
  encryptor:
    algorithm: PBEWithMD5AndDES
    bean: stringEncryptor

● 注册加解密bean

@Bean("stringEncryptor")
public StringEncryptor stringEncryptor(@Value("${jasypt.encryptor.password}") String password){
    StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
    encryptor.setPassword(password);
    encryptor.setAlgorithm("PBEWithMD5AndDES");
    return encryptor;
}

● 生成密文

 public static void main(String[] args) {
        StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
        encryptor.setPassword("sdas$%#^*GHJu");
        encryptor.setAlgorithm("PBEWithMD5AndDES");
        final String url = encryptor.encrypt("jdbc:mysql://172.16.156.158:3306/lucene?characterEncoding=utf-8&useSSL=true&serverTimezone=Asia/Shanghai");
        final String u = encryptor.encrypt("wq");
        final String p = encryptor.encrypt("qifeng");
        System.out.println("url: " + url);
        System.out.println("u: " + u);
        System.out.println("p: " + p);
    }

3、使用

● 配置文件加密
密文使用ENC()包裹

spring:
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    url: ENC(NjKtplPL9XmtxnUCz7ySOM8259+OH3mBf378s5bYNRoogK8hlltoSMOoalABVsRpp+6Q3b7ZsIm3aJERPjv5hSC0lOEJYegyzUNvv3m2Sq0hXZ5qdyLkugNtRhsF7w6seZN7eN/OdVW2QRWchvmCUG7ChLzlMP5NhbBk62/hSFPthLQDMUnHHJv8iT5EB1m8)
    driver-class-name: com.mysql.cj.jdbc.Driver
    username: ENC(4ZqAMYAkPXJmTyBptPa1osuHeD62D4LYtqO1iC70Htd+1ILWTui2ZXW2EDPWkGst)
    password: ENC(b6YpA5JYiWImDqhz5uVeHYLM2K3eJihVbgGfgoaH0hMR3QOljes4Kb0ckvu+xk4s)

● 启动应用时，配置系统属性，idea配置VM选项

java -jar test.jar -Djasypt.encryptor.password=sdas$%#^*GHJu
