springboot 配置文件明文加解密

先引入jar依赖

    com.github.ulisesbocchio
    jasypt-spring-boot-starter
    1.14


    com.github.ulisesbocchio
    jasypt-spring-boot
    1.14

application.yml文件配置如下参数

jasypt:
  encryptor:
    password: 123456

编写测试类生成加密文件

import com.fasterxml.jackson.databind.deser.Deserializers;
import com.ulisesbocchio.jasyptspringboot.annotation.EnableEncryptableProperties;
import org.jasypt.encryption.StringEncryptor;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

@EnableEncryptableProperties
@SpringBootTest(classes=Deserializers.Base.class)
@RunWith(SpringRunner.class)
public class Test {
    @Autowired
    StringEncryptor stringEncryptor;//密码解码器注入

    @org.junit.Test
    public void test() {
        System.out.println("生成加密后的数据库用户名："+stringEncryptor.encrypt("root"));
        System.out.println("生成加密后的数据库密码："+stringEncryptor.encrypt("root"));
    }
}

启动项目后控制台输出：

之后将

数据库密码参数spring.datasource.username=root

配置为生成后的spring.datasource.username=ENC(jAddU0hDWFmN0V+9T6g65g)

数据库密码参数spring.datasource.password=root

配置为生成后的  spring.datasource.password=ENC( jquUppb2TyAUvIPUKLmkHw )

spring:
  datasource:
    url: jdbc:mysql://localhost:3306/Test?useUnicode=true&characterEncoding=UTF-8
    username: ENC(jAddU0hDWFmN0V+9T6g65g==)
    password: ENC(jquUppb2TyAUvIPUKLmkHw==)
    driver-class-name: com.mysql.jdbc.Driver

@Value(“$(参数名)”)获取到的内容就是我们解密之后的内容。

使用jasypt框架处理配置文件参数加密的功能就OK啦
