jasypt快速入门

• 引入依赖

java com.github.ulisesbocchio jasypt-spring-boot-starter 2.1.0

• 配置加密/解密秘钥

yaml jasypt: encryptor: password: Y6M9fAJQdU7jNp5MW

• 加密字符串

```java @Test public class DatabaseTest {

@Autowired
private StringEncryptor encryptor;

@Test
public void getPass() {
    String url =        encryptor.encrypt("jdbc:mysql://localhost:3306/mydb&characterEncoding=utf-8");
    String name = encryptor.encrypt("root");
    String password = encryptor.encrypt("123456");

    System.out.println("database url: " + url);
    System.out.println("database name: " + name);
    System.out.println("database password: " + password);
}

} ```

• 替换明文

```yaml spring: datasource: driver-class-name: com.mysql.cj.jdbc.Driver url: ENC(h20YiPrvNnuuTe096APd3bnG3++Yro=) username: ENC(sT6BztXbJEa71eg3pPGYMQ==) password: ENC(MpSZFJ9ftq+3+VUANZjr0Q==)

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

• 为防止加密秘钥泄露，可在项目部署的时候使用命令传入

shell java -jar xxx.jar -Djasypt.encryptor.password=Y6M9fAJQdU7jNp5MW
