詳解如何保護SpringBoot配置文件中的敏感信息

更新時間：2023年07月28日 09:26:39 作者：242030

使用過SpringBoot配置文件的朋友都知道，資源文件中的內(nèi)容通常情況下是明文顯示，安全性就比較低一些，所以為了提高安全性，就需要對配置文件中的敏感信息進行保護，下面就為大家介紹一下實現(xiàn)方法吧

1、pom依賴

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.6</version>
        <relativePath/>
    </parent>

        </plugins>
    </build>
</project>

2、配置加/解的密碼

# jasypt加密的密匙
jasypt:
  encryptor:
    password: Y6M9fAJQdU7jNp5MW

3、測試用例中生成加密后的秘鑰

package com.jasypt;
import org.jasypt.encryption.StringEncryptor;
import org.junit.Assert;
import org.junit.jupiter.api.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.SpringRunner;
@RunWith(SpringRunner.class)
@SpringBootTest
class SpringBootJasyptApplicationTests {
    @Autowired
    private StringEncryptor encryptor;
    @Test
    public void getPass() {
        String url = encryptor.encrypt("jdbc:mysql://127.0.0.1:3306/test");
        String name = encryptor.encrypt("root");
        String password = encryptor.encrypt("root");
        System.out.println("database url: " + url);
        System.out.println("database name: " + name);
        System.out.println("database password: " + password);
        Assert.assertTrue(url.length() > 0);
        Assert.assertTrue(name.length() > 0);
        Assert.assertTrue(password.length() > 0);
    }
}

下面是輸出加密字符串：

database url: CCGZpukXHOy7xPMVm6//IZi3kQxJQmZuFdrje1KtshlZD0IiwrHTQWcB4J4l1qKe
database name: +DcWhoH0RuZck93R2FSEEg==
database password: gTVoDqbBeaTe2+omIsoXIA==

4、將加密后的字符串替換原明文

server:
  port: 8080
spring:
  # 數(shù)據(jù)庫相關(guān)配置
  datasource:
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: CCGZpukXHOy7xPMVm6//IZi3kQxJQmZuFdrje1KtshlZD0IiwrHTQWcB4J4l1qKe
    username: +DcWhoH0RuZck93R2FSEEg==
    password: gTVoDqbBeaTe2+omIsoXIA==
  jpa:
    hibernate:
      ddl-auto: update
    show-sql: true
  # 返回的api接口的配置，全局有效
  jackson:
   # 如果某一個字段為null，就不再返回這個字段
    default-property-inclusion: non_null
    date-format: yyyy-MM-dd HH:mm:ss
    serialization:
      write-dates-as-timestamps: false
    time-zone: GMT+8
# jasypt加密的密匙
jasypt:
  encryptor:
    password: Y6M9fAJQdU7jNp5MW
