第一种Jasypt加密

  1. maven依赖

不同的spring boot版本引入的jasypt版本不同

<!-- Jasypt加密 -->spring boot 版本号1依赖<dependency>    <groupId>com.github.ulisesbocchio</groupId>    <artifactId>jasypt-spring-boot-starter</artifactId>    <version>2.0.0</version></dependency>spring boot 版本号2依赖<dependency>    <groupId>com.github.ulisesbocchio</groupId>    <artifactId>jasypt-spring-boot-starter</artifactId>    <version>3.0.3</version></dependency>
  1. 在配置核心减少相干配置
jasypt.encryptor.password=henghe #加密密钥

或者

为了避免salt(盐)泄露,反解出明码.能够在我的项目部署的时候应用命令传入salt(盐)值:

java -jar xxx.jar -Djasypt.encryptor.password=henghe

  1. 将application.yml或配置核心中重要的配置改为加密格局
 password: ENC(tnJpIM6iACWO/wRI//7XsbBqy/Mpx6MG1hXe4S7U4cNWmGhajnUSeXmBmQiniKEU)
  1. springboot程序在启动会自动检测appliction.yml或者配置核心中有ENC(xx)的配置并做解密
  2. 加解密的测试类

第二种，自定义class

实现EnvironmentPostProcessor

从Spring Boot 1.3开始，咱们能够在应用程序上下文刷新之前应用EnvironmentPostProcessor来自定义应用程序的Environment。Environment示意以后利用程序运行的环境，它能够对立拜访各种属性源中的属性，如属性文件、JVM零碎属性、零碎环境变量和Servlet上下文参数。应用EnvironmentPostProcessor能够在bean初始化之前对Environment进行批改

EnvironmentPostProcessor能够在创立应用程序上下文之前，增加或者批改环境配置。

EnvironmentPostProcessor`接口实现代表：`ConfigFileApplicationListener

  1. 创立自定义类，实现EnvironmentPostProcessor
package com.yss.henghe.iris.configuration;import org.springframework.boot.SpringApplication;import org.springframework.boot.env.EnvironmentPostProcessor;import org.springframework.core.env.*;import java.util.*;/** * @Description * @Author 86199 * @Date 2021/12/1 14:05 */public class SafetyEncryptProcessor implements EnvironmentPostProcessor{    public static final String SPRING_DATASOURCE_PASSWORD = "spring.datasource.password";    public static final String PASSWORD_ENABLE_ENCRYPT = "password.enable.encrypt";    public static final String TRUE = "true";    @Override    public void postProcessEnvironment(ConfigurableEnvironment environment, SpringApplication application) {        String enableEncrypt = environment.getProperty(PASSWORD_ENABLE_ENCRYPT);        if (TRUE.equals(enableEncrypt)) {            String password = environment.getProperty(SPRING_DATASOURCE_PASSWORD);            Properties properties = new Properties();            byte[] decode = Base64.getDecoder().decode(password);            byte[] messageDe = new byte[0];            try {                messageDe = RSAEncryptDecrypt.decrypt(decode);            } catch (Exception e) {            }            properties.setProperty(SPRING_DATASOURCE_PASSWORD, new String(messageDe));            PropertiesPropertySource propertiesPropertySource = new PropertiesPropertySource(SPRING_DATASOURCE_PASSWORD,                    properties);            environment.getPropertySources().addFirst(propertiesPropertySource);        }    }}
  1. 在META-INF下创立spring.factories，并且引入CustomEnvironmentPostProcessor 类

图片

spring.factories:

org.springframework.boot.env.EnvironmentPostProcessor=\com.yss.henghe.iris.configuration.SafetyEncryptProcessor
  1. 将加密后的明码写入到配置文件中
spring.datasource.password
  1. 公钥私钥生成办法，利用datax工具，能够生成1024,2048等制订要求的公钥秘钥

maven依赖

<dependency>  <groupId>com.alibaba.datax</groupId>  <artifactId>datax-core</artifactId>  <version>0.0.1-SNAPSHOT</version> </dependency>public static void main(String[] args) throws Exception{     String[] initKey = SecretUtil.initKey();      System.out.printf("%s: %s\n","publicKey",initKey[0]);      System.out.printf("%s: %s\n","privateKey",initKey[1]);}
