springboot配置文件属性加密

1.非springboot系统属性加密，也就是自己自定义的属性，可以获取到加密属性之后解密，我用MD5加密演示的解密。

 //获取 application.properties中自定义的 storePassword属性值可以给他加密
@Value("${storePassword}")
    private String password;

// 表示在创建该bean之时自动执行
    @PostConstruct
    public void init() {
        // 调用我们自己的解密方法，这里解密自定义的属性
        password = MD5Util.MD5((password));
    }

2.springboot的系统属性值加密

//给springboot系统属性加密
//如下：
spring.datasource.username={decry}cm9vdA==
spring.datasource.password={decry}SHdqMjAxOCE=

<!--springboot配置系统文件的属性值加密的依赖-->

    //如果属性的字符开头为"{decry}",返回true ，表明属性是加密过的
    @Override

    @Override

    }
