1 在项目中加密

1.1 导包

<dependency><groupId>com.github.ulisesbocchio</groupId><artifactId>jasypt-spring-boot-starter</artifactId><version>3.0.5</version>
</dependency>

1.2 加密

配置文件

jasypt:encryptor:password: study-demoalgorithm: PBEWithMD5AndDESiv-generator-classname: org.jasypt.iv.NoIvGenerator

获取配置文件信息

package com.sky.properties;import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;/*** 应用配置信息** @author wangs* @date 2024/9/21 14:18*/
@Data
@Component
@ConfigurationProperties(value = "jasypt.encryptor")
public class AppProperties {/*** 加密盐值*/private String password;
}

加密代码

package com.sky;import com.sky.properties.AppProperties;
import org.jasypt.encryption.pbe.StandardPBEStringEncryptor;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;import javax.annotation.Resource;@SpringBootTest(classes = SkyApplication.class)
@RunWith(SpringRunner.class)
public class EncryptorTest {/*** MySQL连接信息*/private final static String HOST_NAME = "主机IP";private final static String USERNAME = "数据库用户名";private final static String PASSWORD = "数据库密码";@Resourceprivate AppProperties appProperties;/*** 加密MySQL数据库*/@Testpublic void mysqlEncryptorTest() {StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();// 加密盐值encryptor.setPassword(appProperties.getPassword());String host = encryptor.encrypt(HOST_NAME);String username = encryptor.encrypt(USERNAME);String password = encryptor.encrypt(PASSWORD);System.out.println("host密文："+host);System.out.println("username密文："+ username);System.out.println("password密文："+password);}
}

1.3 修改配置文件

将 1.2 中生成的密文替换配置文件中的明文信息

  datasource:driver-class-name: com.mysql.cj.jdbc.Driverhost: ENC(5+NRySB3LIsgOI2IEFrLaAt96lB0kvyK)port: 3306database: xxx_xxx_xxxusername: ENC(27L2N1KZZnJWGfYjIXRLcA==)password: ENC(f9Dc9EY6TQqmPMqARsO5/g==)

1.4 问题解决

在使用过程中，遇到了一个问题

failed to bind properties under spring.datasource.druid.password' to java.lang.String

出现这个问题的时候，在配置文件中，我并没有加上最后面的两行，加上后解决问题

jasypt:encryptor:password: study-demoalgorithm: PBEWithMD5AndDESiv-generator-classname: org.jasypt.iv.NoIvGenerator
