基于SpringCloud的Microservices架构实战案例-配置文件属性内容加解密

使用过SpringBoot配置文件的朋友都知道，资源文件中的内容通常情况下是明文显示，安全性就比较低一些。打开application.properties或application.yml，比如mysql登陆密码，redis登陆密码以及第三方的密钥等等一览无余，这里介绍一个加解密组件，提高一些属性配置的安全性。

jasypt，官方给出的释意是：

Jasypt is a java library which allows the developer to add basic encryption capabilities to his/her projects with minimum effort, and without the need of having deep knowledge on how cryptography works.

simplemall项目也采用此加密组件，结合Spring Boot使用。国外大神Ulises Bocchio写了一个Spring Boot下用的工具包，Github地址：https://github.com/ulisesbocchio/jasypt-spring-boot，下面介绍下jasypt在Spring Boot的用法。

1、引入maven依赖


<dependency>
<groupId>com.github.ulisesbocchio</groupId>
<artifactId>jasypt-spring-boot-starter</artifactId>
<version>1.14</version>
</dependency>

2、配置加密参数

在application.yml 中增加配置

jasypt:
encryptor:
#这里可以理解成是加解密的时候使用的密钥
password: your password

在application.properties中增加配置

jasypt.encryptor.password=your password

此处密码的生成可以通过两种方式生成，写main函数生成和直接采用jar命令方式。本处采用main函数的方式，此代码位于account-serv的test包中。

package com.simplemall.account.test;
import org.jasypt.encryption.StringEncryptor;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import com.simplemall.account.AccountServApplication;
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@SpringBootTest(classes = AccountServApplication.class)
public class Jasyptest {
@Autowired
StringEncryptor encryptor;
@Test
public void getPass() {
String result = encryptor.encrypt("root");
System.out.println(result);
Assert.assertTrue(result.length() > 0);
}
}

3、升级application.properties/yml中相应的配置项

旧有配置

#mysql database config
spring.datasource.url=jdbc:mysql://localhost:3306/micro_account?useUnicode=true&characterEncoding=UTF-8&characterSetResults=UTF-8&zeroDateTimeBehavior=convertToNull
#use jasypt to encrypt username/password
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driverClassName=com.mysql.jdbc.Driver

升级后配置

#mysql database config
spring.datasource.url=jdbc:mysql://localhost:3306/micro_account?useUnicode=true&characterEncoding=UTF-8&characterSetResults=UTF-8&zeroDateTimeBehavior=convertToNull
#use jasypt to encrypt username/password
spring.datasource.username=ENC(BnBr3/idF0PH9nd20A9BXw==)
spring.datasource.password=ENC(BnBr3/idF0PH9nd20A9BXw==)
spring.datasource.driverClassName=com.mysql.jdbc.Driver
