SpringBoot+jasypt-spring-boot-starter实现配置文件明文加密

news2024/11/25 4:01:47

1.使用环境

springboot:2.1.4.RELEASE
JDK:8
jasypt-spring-boot-starter:3.0.2

2.引入依赖

!-- 配置文件加密 -->
<dependency>
    <groupId>com.github.ulisesbocchio</groupId>
    <artifactId>jasypt-spring-boot-starter</artifactId>
    <version>3.0.2</version>
</dependency>


<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.mybatis.spring.boot</groupId>
    <artifactId>mybatis-spring-boot-starter</artifactId>
    <version>2.0.1</version>
</dependency>
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.33</version>
</dependency>

<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <optional>true</optional>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

3.application.properties配置

server.port=8080

### mybatis
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.xx.xx  

### xxl-job, datasource
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/xxx?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=ENC(jGfd15IFYKMjMW5bUYp06BQ8OCdHTXi3zbD4j9tw6U3PPvvA5GS8zn10kgVmgxXY)
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

#加密盐值，获取加密后的值后删除，在vmOptions配置(如下图)
jasypt.encryptor.password=123adf

加密后，可删除jasypt.encryptor.password配置；发版时可在命令行中配置
在这里插入图片描述

4.明文加密

@SpringBootTest
@RunWith(SpringRunner.class)
public class D2ApplicationTests {

    @Resource
    private StringEncryptor jasyptStringEncryptor;
    @Test
    public void contextLoads() {
       String pwd =  jasyptStringEncryptor.encrypt("root");
        System.out.println("pwd:" + pwd);
    }

}

5.所遇问题

org.jasypt.exceptions.EncryptionOperationNotPossibleException:
