springgboot集成Jasypt 加密

1、加密工具方法（可以自行抽出来打成包运行）：
import org.jasypt.encryption.pbe.PooledPBEStringEncryptor;
import org.jasypt.encryption.pbe.StandardPBEByteEncryptor;
import org.jasypt.encryption.pbe.config.SimpleStringPBEConfig;

/**

 * @Descpription TODO
 */
public class JasyptUtils {
    /**
     * Jasypt生成加密结果
     *
     * @param password 配置文件中设定的加密密码 jasypt.encryptor.password
     * @param value    待加密值
     * @return
     */
    public static String encryptPwd(String password, String value) {
        PooledPBEStringEncryptor encryptOr = new PooledPBEStringEncryptor();
        encryptOr.setConfig(cryptOr(password));
        String result = encryptOr.encrypt(value);
        return result;
    }

    /**
     * 解密
     *
     * @param password 配置文件中设定的加密密码 jasypt.encryptor.password
     * @param value    待解密密文
     * @return
     */
    public static String decyptPwd(String password, String value) {
        PooledPBEStringEncryptor encryptOr = new PooledPBEStringEncryptor();
        encryptOr.setConfig(cryptOr(password));
        String result = encryptOr.decrypt(value);
        return result;
    }

    /**
     * @param password salt
     * @return
     */
    public static SimpleStringPBEConfig cryptOr(String password) {
        SimpleStringPBEConfig config = new SimpleStringPBEConfig();
        config.setPassword(password);
        config.setAlgorithm(StandardPBEByteEncryptor.DEFAULT_ALGORITHM);
        config.setKeyObtentionIterations("1000");
        config.setPoolSize("1");
        config.setProviderName(null);
        config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
        config.setStringOutputType("base64");
        return config;
    }

    public static void main(String[] args) {
        // 加密
        //System.out.println(encryptPwd("EbfYkitulv73I2p0mXI50JMXoaxZTKJ7", "root@1234"));
        // 解密
//        mysql@1234
        //System.out.println(decyptPwd("sunsoft123", "a8fd7i0uUYPHW7ZhLF4uyA=="));

//        root@1234
//        System.out.println(decyptPwd("EbfYkitulv73I2p0mXI50JMXoaxZTKJ7", "tdHzge8YvviOJaiV/+P6uQ9wgB44D1aH"));

        String password = "sunsoft123";
        String data = "123456";

        PooledPBEStringEncryptor encryptor = new PooledPBEStringEncryptor();
        SimpleStringPBEConfig config = new SimpleStringPBEConfig();
        config.setPassword(password);
        config.setAlgorithm("PBEWithMD5AndDES");
        config.setKeyObtentionIterations("1000");
        config.setPoolSize("1");
        config.setProviderName(null);
        config.setProviderClassName(null);
        config.setSaltGeneratorClassName("org.jasypt.salt.RandomSaltGenerator");
        config.setIvGeneratorClassName("org.jasypt.salt.NoOpIVGenerator");
        config.setStringOutputType("base64");
        encryptor.setConfig(config);

        System.out.println(encryptor.encrypt(data));

    }

}

2. pom.xml增加jasypt-spring-boot-starter依赖

       <dependency>
            <groupId>com.github.ulisesbocchio</groupId>
            <artifactId>jasypt-spring-boot-starter</artifactId>
            <version>2.1.1</version>
        </dependency>

3、application.properties使用加密了的配置

spring.datasource.username=ENC(25j23414123FYdxkWJ+YKMZYHl34==)
spring.datasource.password=ENC(25gjpuolmUcBoW343yuyJ+343344==)

4、配置密码

可配置在application.properties文件中（这种方式不安全）

jasypt.encryptor.password=123456

在JVM启动参数中设置

-Djasypt.encryptor.password=123456
