第一种Jasypt加密
- maven依赖
spring boot 版本号1依赖
com.github.ulisesbocchio
jasypt-spring-boot-starter
2.0.0
spring boot 版本号2依赖

jasypt-spring-boot-starter
3.0.3
- 在配置中心增加相关配置
jasypt.encryptor.password=henghe #加密密钥 或者
为了防止salt(盐)泄露,反解出密码.可以在项目部署的时候使用命令传入salt(盐)值:
java -jar xxx.jar -Djasypt.encryptor.password=henghe如果您正在学习Spring Boot，那么推荐一个连载多年还在继续更新的免费教程：http://blog.didispace.com/spr...
- 将application.yml或配置中心中重要的配置改为加密格式
password: ENC(tnJpIM6iACWO/wRI//7XsbBqy/Mpx6MG1hXe4S7U4cNWmGhajnUSeXmBmQiniKEU)- springboot程序在启动会自动检测appliction.yml或者配置中心中有ENC(xx)的配置并做解密

第二种，自定义class
实现EnvironmentPostProcessor
从Spring Boot 1.3开始，我们可以在应用程序上下文刷新之前使用
EnvironmentPostProcessor来自定义应用程序的Environment。Environment表示当前应用程序运行的环境，它可以统一访问各种属性源中的属性，如属性文件、JVM系统属性、系统环境变量和Servlet上下文参数。使用EnvironmentPostProcessor可以在bean初始化之前对Environment进行修改EnvironmentPostProcessor可以在创建应用程序上下文之前，添加或者修改环境配置。EnvironmentPostProcessor`接口实现代表：`ConfigFileApplicationListener- 加密解密工具类

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)) {
